Ultra Training

The first time I started looking up 50K finish times, I made the same mistake a lot of runners make.

I wanted one clean answer.

One number. One normal finish time. One simple way to know where I’d fit.

But that’s not really how a 50K works.

You’ll see one runner knock it out in 5 hours and make it look almost casual. Then you’ll see someone else out there for 8, 10, even 12 hours on the same distance, fighting through climbs, heat, stomach problems, cramps, and whatever else the trail decides to throw at them. And the strange part is… both efforts can be completely legit.

That’s what makes ultrarunning so confusing at first.

The distance stays the same, but the experience changes wildly depending on the course, the weather, the elevation, your fueling, your pacing, and how badly you mess things up in the first half without realizing it yet. A flat road 50K is one thing. A hilly trail 50K is a completely different animal. Same 31 miles on paper. Not even close in real life.

I learned that pretty quickly.

At first I thought a 50K was just a marathon with a few extra miles added on top. That sounds reasonable until you’re deep into one, holding a sticky gel, climbing something steep, and realizing your legs have stopped negotiating with you. That’s usually where the race starts teaching you what it actually is.

So if you’re here trying to figure out what a good 50K time looks like, I want to make this simple.

Yes, there are averages. Yes, there are rough benchmarks. But context matters more than almost anything else. Because in ultras, the finish time by itself tells a very incomplete story. A slower time on a harder course can be the better run. A “good” 50K time for one runner might be a complete disaster for another. And for a first-timer, the smartest goal is usually not chasing some impressive number.

It’s finishing strong enough that the whole thing doesn’t fall apart in the last stretch.

That’s the real conversation.

And once you understand that, 50K times start making a lot more sense.

The 50K Numbers You Need To Know

Most recreational runners finish a 50K somewhere in that 4 to 6 hour range if it’s on the road or a smoother trail.

But when you zoom out and look at larger datasets, the overall average lands closer to 7–8 hours, mostly because tougher courses and back-of-pack finishes pull that number up.

Elites might come through in around 3½ to 4 hours on a fast course.

On the other end, a lot of first-timers—especially on trails—are in that 6 to 8+ hour range, sometimes longer depending on how the day goes. You’ll see some runners cruise under 4 hours “no problem,” and others out there for 8, 10, even 12 hours on the exact same course.

Trail ultras change everything.

It’s common to lose 1–2 minutes per mile compared to road pace just from terrain. On smoother dirt, the difference might be small. But once you add hills, rocks, or technical sections, that gap grows quickly.

At that point, your finish time depends less on your 5K speed and more on things like terrain, elevation, weather, pacing, fueling, and how well you manage your ego over a long day.

Why 50K Times Are So Confusing

This is where most new ultrarunners get stuck.

You ask a simple question—what’s a normal 50K time—and you get answers that are all over the place. Some people say 5 hours. Others say 8. Both sound confident. Both sound right.

And somehow that makes it worse.

Terrain & Elevation (This Changes Everything)

The biggest factor is the course.

A flat 50K on the road or a smooth dirt path can feel like a long marathon. You might only be slightly slower per mile than your marathon pace.

Take that same distance into the mountains, though, and it’s a completely different experience.

Rocks, roots, mud, long climbs, technical descents—each one slows you down in ways that don’t show up on a simple pace chart.

I’ve run a flat 50K in about 5 hours, then a year later ran a hillier one in over 7 hours, even though I was fitter.

That’s how much terrain matters.

And it messes with your head, because the time alone doesn’t tell the story. A slower finish on a harder course can actually be the better performance.

That’s something you have to learn the hard way sometimes.

Pacing & Bonking (Where It Usually Goes Wrong)

The next factor is pacing.

This is where most first-timers get caught.

You feel good early on. Fresh legs, good energy, everything seems under control. So you run a bit faster than you probably should. Nothing crazy, just slightly ahead of what feels sustainable.

Then around 30K, things start to shift.

And by mile 25 or so, you’re hanging on.

I’ve lived that.

You go from thinking you’re having a great race to just trying to survive the last stretch. It’s not subtle either. It hits all at once.

There’s research showing that the runners who perform best in ultras aren’t the fastest early on. They’re the ones who slow down the least over time.

That’s a big difference.

Because it means the goal isn’t to go fast early. It’s to avoid falling apart later.

And that takes restraint.

Fueling & Hydration (The Quiet Mistake)

Fueling is another one that sneaks up on you.

In shorter races, you can sometimes get away with not eating enough. In a 50K, that doesn’t work.

If you don’t stay on top of calories, you eventually hit that low-energy state where everything slows down. Not just physically, but mentally too. It turns into this long stretch of just trying to keep moving.

I’ve had runs where I got this wrong.

Started fine, felt okay for a couple of hours, then suddenly everything dropped. Pace slowed, focus disappeared, and it became more about not stopping than actually running.

Hydration adds another layer.

Too little fluid, and things start to break down. Too much without electrolytes, and that causes its own problems. I’ve had a run where I got this wrong in the heat, and by the later miles I was lightheaded and struggling to stay steady on the trail.

Those mistakes don’t show up right away.

They show up late, when you don’t have much left to fix them.

Data Confusion (Why Everything Online Feels Off)

Then there’s the data you see online.

Strava, forums, race reports—most of it shows the good days.

You see someone’s 50K time where everything went right. What you don’t see are the races where they struggled for 8 hours or more.

So it creates this skewed picture.

You start thinking everyone is running 50Ks in 4–5 hours, and if you’re not there, something’s wrong.

But that’s not reality.

A lot of runners are finishing much later, especially on harder courses. They just don’t talk about it as much.

I remember reading discussions where people argued about what “average” meant. Some said 5–6 hours. Others said 7–8. Both were right, just talking about different kinds of races.

That’s what makes it confusing.

You’re comparing numbers without context.

The Real Issue

The problem isn’t that the times are inconsistent.

It’s that we expect them to be consistent.

A 50K isn’t a fixed experience.

It changes depending on the course, the conditions, and how you handle everything over those hours.

Once you accept that, the numbers stop feeling so confusing.

They start making sense.

The Science Behind Your 50K Effort 

Let’s step away from stories for a bit and look at what’s actually happening in your body during a 50K.

Because once you understand this part, a lot of things start making sense. The slowdown, the fatigue, that feeling of being completely drained late in the race—it’s not random. It’s not you being “off.” It’s your body doing exactly what it’s supposed to do under that kind of stress.

Intensity — Why a 50K Feels Slower (But Isn’t Easier)

A 50K is not run at the same intensity as shorter races.

For most recreational runners, you’re sitting somewhere around 65–75% of your VO₂max. In simpler terms, that’s a moderate effort. You can talk a bit, you’re not sprinting, but you’re definitely working. It usually lines up with around 70–80% of your max heart rate.

That’s a big shift from something like a 10K or half marathon, where you’re pushing much closer to your limit.

In a 50K, you can’t hold that kind of intensity for hours.

So your body settles into something more sustainable.

And this is where the fuel system changes.

You rely more on fat as a fuel source. It burns slower, but there’s a lot more of it available. That’s why people talk about “fat adaptation” in ultras. But that doesn’t mean carbs don’t matter. They still do. Even at lower intensity, you’re burning a mix of fat and glycogen.

If that glycogen runs out completely, everything falls apart.

I think of it like a hybrid engine.

You’re running on both systems. If one drops too low, the whole thing struggles.

The 30K Wall (Where Everything Catches Up)

This is where things usually shift.

Around 30K, give or take, a few things tend to hit at once.

First, glycogen starts running low. Most people have roughly enough stored energy for around 20 miles. After that, you’re relying more heavily on whatever you’re taking in during the run. If you’ve been under-fueling, this is where it shows up.

It’s not gradual either.

You go from feeling okay to suddenly feeling empty.

I’ve had runs where it felt like someone flipped a switch. Same pace, same effort, and then suddenly nothing was there. Legs heavy, mind foggy, everything slowed down.

That’s not a lack of toughness.

That’s fuel.

At the same time, muscle damage is building.

Every step, especially downhill, puts stress on your muscles. Over time, that creates tiny tears. You don’t notice it early, but by the later miles, your legs start to feel stiff and unresponsive.

That “concrete legs” feeling?

That’s part of it.

Then there’s the coordination side.

Your nervous system starts to fatigue too. You might notice your form slipping, your posture collapsing a bit, maybe even tripping more than usual. That’s not clumsiness. That’s your system getting tired of sending the same signals over and over.

Put all of that together, and it’s not surprising that pace drops in the final stretch.

It would actually be strange if it didn’t.

Why Small Mistakes Get Bigger Later

This is the part that catches people off guard.

Something small early on—going a bit too fast on a climb, skipping a gel, not drinking enough—doesn’t feel like a big deal at the time.

But later, it grows.

Because by the second half of the race, your margin is gone.

I’ve seen it in myself and in runners I’ve worked with. Everything feels manageable early, then suddenly it isn’t. Not because something new happened, but because everything from earlier caught up at once.

That’s why ultras feel unpredictable.

They’re not really unpredictable.

They’re just delayed.

Age & the “Ultra Prime”

This one surprised me when I first came across it.

Peak performance in ultras often shows up later than in shorter races. Late 30s, early 40s, sometimes even beyond that. There’s data showing peak speed around age 40 for 50K runners.

And when you think about it, it makes sense.

You need endurance, patience, pacing awareness, and the ability to handle long stretches of discomfort. Those things tend to improve with experience, not just raw fitness.

I’ve coached runners who didn’t start ultras until their 40s or 50s and still improved year after year.

You also see it in races.

You’ll be out there struggling late, and someone older, moving steadily, passes you without much drama. Not fast, not flashy, just consistent.

That’s experience showing up.

The Runner’s High (Not What You Think)

Before I ran ultras, I had this idea that I’d feel amazing for most of it.

Like I’d just settle into a rhythm and ride that feeling all the way through.

That’s not how it works.

You do get moments.

Early on, maybe mid-race, there are times where everything feels good. You’re moving well, maybe even smiling without realizing it. That’s real.

But it doesn’t last.

As fatigue builds, as hydration and fueling get harder to manage, that feeling fades. The body starts sending stronger signals. Discomfort, tiredness, that sense of being worn down.

I’ve had races where I felt great at mile 15 and completely done by mile 28.

Same race.

That’s normal.

The mistake is expecting the good feeling to carry you through.

It won’t.

What carries you through is having a plan for when it doesn’t.

Eating when you don’t feel like it. Slowing down when you need to. Talking yourself through the rough patches without overreacting to them.

The Bigger Picture

Once you understand what’s happening under the surface, the whole experience makes more sense.

You stop taking the slowdown personally.

You stop thinking something’s wrong just because things got hard.

Because they’re supposed to get hard.

Your body is running low on quick fuel, your muscles are taking damage, your system is getting tired. That’s the cost of going that far.

And the goal isn’t to avoid it.

It’s to manage it.

Stay steady early. Fuel consistently. Respect the distance.

Because when everything starts to stack up late in the race, that’s what keeps you moving.

How to Train & Pace for Realistic 50K Times 

Now we get into the part that actually matters when you’re out there doing it.

Because understanding the science is one thing, but it doesn’t help much if you don’t know how to apply it. A 50K isn’t something you can wing. You don’t cram for it the last few weeks and hope it works out. It’s built over time, slowly, with a lot of small decisions that either help you later… or come back to bite you around mile 25.

1. Train Smart (Not Just Hard)

You can’t rush this.

The biggest mistake I see, and I made it myself, is trying to jump too far too quickly. If your longest run is 15 miles, you don’t suddenly go to 25 the next week. That’s how you end up tired, injured, or both. A gradual build works better. Something like a 10% increase per week is a good ceiling, not a target.

Most solid 50K plans will bring your long runs into that 20–22 mile range. You don’t need to hit the full 31 miles in training, but you need to get close enough that race day doesn’t feel completely foreign.

What helped me more than anything was back-to-back long runs.

Something like 16 miles on Saturday, then 10–12 on Sunday. That second run feels rough at first. Legs are heavy, everything feels off, and you question why you’re doing it. But that’s the point. It teaches you how to move when you’re already tired, which is exactly what the second half of a 50K feels like.

The first time I did it, I hated it.

By race day, I understood why it mattered.

Terrain matters too.

If your race is on trails, train on trails. I learned that the hard way. I trained mostly on roads for a trail 50K once, and while my endurance was there, my ankles and stabilizers weren’t ready for uneven ground. I ended up rolling my ankle mid-race.

After that, I stopped guessing.

You train for the surface you’re going to run on.

The Mistake I Made (And See All the Time)

I used to treat every long run like it was a race.

I’d go out trying to hit strong splits, pushing the pace just to prove I could. It felt productive. It felt like I was getting faster.

What it actually did was wear me down.

I was always a little too tired, sometimes slightly injured, and I never really learned how to pace an ultra. So when race day came, I did exactly what I had practiced—I went out too fast.

And I paid for it later.

That’s the thing.

Training teaches you habits.

If you always push, you’ll push on race day.

If you practice patience, you’ll have it when it matters.

2. Pacing Strategy (Where Most Races Are Won or Lost)

The best advice I ever got was simple.

Start slower than your ego wants to.

And honestly, slower than that.

The first part of a 50K feels easy. Almost suspiciously easy. You’ll think you’re holding back too much. That’s exactly where you want to be. If it feels even slightly hard in the first hour, you’re probably going too fast.

A rough way to think about it is adding 10–15% to your marathon pace, assuming similar terrain. So if you’re around a 4-hour marathoner, your 50K pace might sit somewhere around 10:00–10:30 per mile, before you even factor in hills or technical sections.

And if it’s hot or the course is tough, you slow down even more.

I’ve learned to treat the first half of a 50K as a setup.

If I get to halfway and feel controlled—legs okay, breathing steady—I know I did it right. If I get there already struggling, I know I made it harder than it needed to be.

Walking (The Thing That Feels Wrong Until It Doesn’t)

This one took me time to accept.

Walking felt like failure.

But in ultras, it’s just another gear.

Walking steep hills often costs you very little time compared to trying to run them, but it saves a lot of energy. That energy shows up later, when everyone else is slowing down.

The first time I leaned into this, I had a moment that stuck with me. I was hiking a climb around mile 20, moving steadily, and passed someone who was trying to run it but barely moving faster. I got to the top feeling okay, while they were completely spent.

That race ended up being one of my better ones.

Not because I ran harder.

Because I managed my effort better.

How I Break It Down Mentally

I don’t think of a 50K as one long race.

I break it into sections.

First half is just getting there feeling good.

Second half is where the work starts.

And the final 10K… that’s where you deal with whatever you’ve got left.

Most people don’t speed up at the end of a 50K.

The goal is to slow down as little as possible.

And that comes from being patient early.

3. Fuel & Hydration (This Decides Your Race)

If pacing is the structure, fueling is what keeps it from collapsing.

You need to eat.

Not when you feel like it.

Before that.

A good starting point is around 200–300 calories per hour, mostly from carbs. That can be gels, chews, sports drink, or real food. It doesn’t matter what, as long as it works for you and you can keep it down.

I usually set a loose schedule.

Every 30–40 minutes, I take something.

Early on, you won’t feel like you need it.

That’s when it matters most.

Because once you feel depleted, it’s already too late to fully fix.

Hydration works the same way.

Small, steady sips. Not big swings.

In cooler conditions, maybe around 500 ml per hour. In heat, it can be double that. And electrolytes matter. I’ve learned that the hard way too. One humid run, I relied on water alone, and by the later miles I was cramping and feeling off.

Now I don’t skip electrolytes.

The Mistake You Only Make Once

I tried skipping gels once in a race.

Felt good early, thought I could get away with it.

I didn’t.

Everything fell apart later. Pace dropped, energy disappeared, and I spent the last part of the race just trying to finish.

That’s when it really sticks.

You don’t skip fueling.

4. Rest & Recovery (The Part People Ignore)

Training isn’t just what you do when you run.

It’s also what you do when you don’t.

I build in easier weeks every few weeks, cutting volume by about 20–30%. It feels like you’re doing less, but that’s when your body actually catches up and adapts.

Without that, you’re just stacking fatigue.

Sleep matters more than most people want to admit.

I’ve had small issues hang around for weeks, then disappear once I backed off and slept more. It’s not complicated, but it’s easy to ignore.

Recovery work helps too.

Stretching, foam rolling, light movement. Nothing extreme, just enough to keep things from tightening up too much. After long weekends, I’ll spend some time loosening up, maybe legs up against the wall for a bit. It’s simple, but it helps.

The Bigger Point

You don’t need perfect training.

You need consistent, honest training.

Build gradually. Stay patient. Fuel properly. Rest when you need it.

Because a 50K doesn’t reward the runner who pushes the hardest early.

It rewards the one who can keep going when everything starts to stack up.

And that comes from how you train.

Not just how hard you train.

Nuance, Limits & Personal Reality  

Before wrapping this up, it’s worth pulling things back a bit.

Because there’s a lot of advice out there, and not all of it applies equally to everyone. Some of it sounds clear and confident, but once you dig into it, there’s always context behind it.

The “Average Time” Trap

People love asking for the average 50K time.

And on paper, you’ll see numbers like 7 hours.

But that number doesn’t mean much on its own.

A flat road 50K with good conditions might have an average closer to 5–6 hours. A technical mountain race might average 8 hours or more.

I’ve run a 50K in 5 hours and placed mid-pack.

I’ve run another in 7 hours and placed much higher.

Same distance.

Completely different effort.

So chasing an “average” doesn’t really help.

It just creates expectations that don’t match your race.

Body, Background & Reality

Every runner shows up with a different starting point.

Body weight, injury history, training background, even things like heat tolerance or altitude exposure—they all play a role.

A heavier runner might expend more energy per step. An older runner might need more recovery. Someone with a long endurance background might handle the distance better even without speed.

And that’s fine.

You’ll see all kinds of runners in ultras.

Some built for speed, some built for endurance, some just stubborn enough to keep going.

And they all find a way to finish.

Conflicting Advice (And Why It Happens)

If you read enough, you’ll notice something.

Advice often contradicts itself.

Run by feel. Follow strict pacing.

Walk hills. Never walk.

Eat constantly. Eat only when needed.

So which one is right?

It depends.

I’ve tried strict pacing plans before. Detailed splits, heart rate targets, everything mapped out. Then the race didn’t match the plan—weather changed, terrain felt different—and I stuck to the plan anyway.

That didn’t end well.

On the other hand, I’ve also gone too far the other way and just run by feel, only to realize later that adrenaline tricked me into going too fast early.

The middle ground works best.

Have a plan, but adjust when things change.

What Actually Works

The best approach is the one that fits you.

Not what worked for someone else, not what sounds impressive, but what keeps you moving and finishing strong.

Some runners do better with structure.

Others do better with flexibility.

Some need more volume.

Others break down if they push too far.

You figure that out over time.

That’s why I always tell runners—take advice, but pay attention to your own patterns.

Because in the end, you’re the one running the race.

The Bigger Picture

There isn’t one right way to run a 50K.

There are principles that help—pace conservatively, fuel consistently, respect the terrain—but how you apply them will always be a little different.

And that’s not a problem.

That’s part of it.

Because the goal isn’t to follow a perfect plan.

It’s to find a way that works for you… and gets you to the finish.

FAQ  

1. What finish time should I expect for my first 50K?

It depends more than most people want it to.

If you’re coming from a marathon background—say around a 4-hour marathon—you can use that as a rough anchor. Add somewhere around 10–25% to your pace per mile, then layer in whatever the course throws at you. So if you’re running around 9:00 per mile in a marathon, you might land closer to 10:00 pace in a 50K on similar terrain, which puts you just over 5 hours.

That’s the cleaner version.

The messier, more realistic version is this.

Most first-timers, especially on trails, end up somewhere in the 6 to 8 hour range. And that’s not a sign something went wrong. That’s just what happens when you combine distance, terrain, fueling, and time on feet. Aid stations slow you down, hills slow you down, small decisions add up.

Finishing a 50K is the main thing.

The time is just a number attached to it.

2. How do I pace a 50K using my marathon time?

The simplest way is to start slower than your marathon pace.

Not slightly slower. Noticeably slower.

Something like 10–15% slower per mile is a good starting point. If your marathon pace is 8:00, you’re probably better off starting closer to 9:00 pace in a 50K, then adjusting for hills and terrain as you go.

But here’s where it gets different.

Pacing in a 50K isn’t steady the way a marathon is. It moves around. You might be running 9-minute miles on flats, hiking hills at 13-minute pace, then moving faster again on descents. That’s normal.

The goal isn’t even pace.

It’s effort.

If the effort stays controlled early, you give yourself a chance later. And if you get to the last 10K feeling okay, that’s when you can decide if you want to push a bit more.

3. Should I be worried if I’m walking a lot?

No.

And honestly, this is one of the biggest mental shifts.

Walking in ultras isn’t something that happens when things go wrong. It’s part of how the race is run. Even strong runners walk at times—steep climbs, technical sections, while eating or drinking.

I’ve seen people power-hike hills at almost the same speed as someone trying to run them, but using less energy. Then they get to the top and keep moving while the other runner needs to recover.

That’s the difference.

If you’re walking, do it with intent. Keep moving, stay engaged. It’s not a break, it’s just a different gear.

And once you accept that, the whole race feels more manageable.

4. How much should I eat and drink during a 50K?

You need to eat more than you think.

A good starting point is around 200–300 calories per hour, mostly from carbohydrates. That could be gels, chews, sports drink, or even real food if your stomach handles it well. The exact source doesn’t matter as much as consistency.

Start early.

Within the first 30–45 minutes, even if you don’t feel like you need it yet. Because once you feel depleted, you’re already behind.

Hydration works the same way.

Small, steady sips instead of big swings. In cooler weather, maybe around 500 mL per hour. In heat, it can be closer to a liter or more. Electrolytes matter too, especially if you’re sweating a lot.

And this part matters more than anything.

Practice in training.

You don’t want race day to be the first time you try something new.

5. Will I lose weight during a 50K?

Not in the way most people think.

You might lose a bit of weight during the race, but it’s mostly water and glycogen, not actual fat. And sometimes, the opposite happens. You finish, and the next day you weigh more.

That’s inflammation.

Your body holding onto fluid to repair itself.

I’ve seen it happen, and it throws people off.

The bigger point is this.

A 50K isn’t a weight-loss tool.

If anything, your body needs more fuel during this kind of effort, not less. Trying to restrict calories during a race is a fast way to end up struggling late.

Focus on finishing.

The rest takes care of itself.

6. How long should I train before running a 50K?

Longer is usually better.

If you already have a solid base, something like 3 to 6 months of focused training works for most people. Closer to 6 months gives you more room to build gradually and adjust when things don’t go perfectly.

Shorter builds—10 to 12 weeks—can work if you’re already in good shape, but there’s less margin for error.

Key parts of training stay pretty consistent.

You build your long runs into that 20–22 mile range. You might include back-to-back long days to simulate fatigue. And if your race is on trails, you spend time on trails.

You also practice the small things.

Carrying gear, fueling, maybe running in the dark if your race might stretch that far.

All of that takes time to figure out.

So if you’re unsure, give yourself more time.

It usually makes the whole experience smoother.

Final Coaching Takeaway  

The real win in a 50K isn’t the number on your watch.

It’s getting to the finish line at all.

When you cross it, you’re not thinking about pace charts or averages.

You’re thinking about everything it took to get there.

The early mornings. The long runs where things didn’t go well. The moments during the race where you weren’t sure you could keep going, and then somehow you did.

You’ll be tired. Probably sore in places you didn’t expect. Maybe a little sunburned. Maybe holding back tears or not bothering to hold them back at all.

And it feels… worth it.

Not because of the time.

Because you did something that, at some point, felt out of reach.

I remember finishing one of my ultras and not even looking at my watch right away. I just stood there, trying to process it. All the training, all the doubt, everything that led up to that moment.

That’s what stays with you.

The time is just the record.

The experience is the part that changes you.

And once you go through it, something shifts.

You stop thinking in terms of “can I do this?”

You start thinking, “what’s next?”

Because whether it took you 5 hours or 9, you still covered the same 50K.

And that counts for everything.

It was 9 PM on a wet, sticky Bali night when I ran the fastest 50K of my life.

No big crowd. No huge finish-line moment. No music blasting. Just darkness, sweat drying on my skin, a headlamp cutting through the mist, and me trying to hold myself together over the last stretch of a very long race.

When I crossed the line and saw 4:48, I honestly just stood there for a second and stared at my watch like it was lying to me. At 42 years old, in that kind of heat and humidity, that was my best 50K ever. And the strange thing is… it didn’t feel flashy. It felt controlled. Calm. Like I had finally learned how to respect the distance instead of trying to bully my way through it.

That wasn’t how my first 50K went.

The first time I tried it, I made the classic mistake a lot of men make. I treated it like a marathon with a little bonus suffering at the end. I went out too fast, fueled badly, ignored the warning signs, and spent the final part of the race falling apart one piece at a time. I finished, sure, but it was ugly. The kind of ugly that makes you swear you’re never doing this again.

Then, like most runners, I did it again anyway.

And over time, I started to see something. The 50K is not just about fitness. It’s about patience, control, fueling, terrain, and keeping your ego from wrecking the whole day before the race has even started. That lesson hit me through my own mistakes first, then again and again through coaching other runners who made the exact same ones.

So in this article, I want to break down what a 50K really does to the male body, why so many men get this distance wrong, and what actually helps if you want to run it well instead of just survive it. Because the 50K does not reward swagger. It rewards respect. And if you give it that, it can give you one of the best race experiences of your life.

Why 50K Bites So Many Men

The Male Ego Trap. Let’s just say it straight. Male ego shows up a lot in ultras. I don’t mean that as a stereotype, just something I’ve seen over and over, including in myself.

The race starts, and suddenly it feels like a 10K. Guys take off hard, chasing position early like it matters. I’ve done it too—charging up the first hill just to pass someone, breathing harder than I should be that early in a 31-mile race.

There’s this quiet urge to win something in the first hour. To feel strong, to not look like you’re struggling. But the race isn’t decided there. Not even close.

I’ve seen runners fly past me in the first 10K and then later, around 40K, they’re bent over, cramping, barely moving. That early effort always shows up somewhere.

The problem is we tell ourselves we can push through anything. So we ignore the early signals—a small twinge, a bit of nausea, that feeling that the pace might be slightly off. We keep going because backing off feels like losing.

Then the 50K finds that weakness and leans into it.

The runners who avoid this are usually the ones finishing well. They let others go early, settle into their own rhythm, and slowly move through the field as the race unfolds.

Common issues in male 50K attempts. Another pattern I see is a kind of overconfidence in preparation. Some runners skip longer or more specific training runs because they’ve done a marathon before and assume that covers it.

It doesn’t.

If your longest run was 20 miles on flat roads, and you show up to a hilly 50K, your legs are going to feel it. I learned that myself when I tried a trail 50K after mostly road training. The descents alone were enough to wreck my quads.

Fueling is another big one. I’ve heard so many versions of the same thing: “I don’t like gels, I’ll just figure it out at aid stations.” That usually doesn’t end well.

I had a friend who drank beer the night before his race for carbs and then ran the whole 50K on water alone. No electrolytes. By mile 28 he was cramping so badly he had to stop completely.

Cramps usually come from a mix of fatigue, dehydration, and electrolyte imbalance. Not enough sodium combined with too much plain water just makes things worse. You dilute what little sodium you have.

I’ve made that mistake too. I once skipped bringing salt tablets to a hot race and ended up dealing with full-body cramps that turned my stride into something awkward and barely runnable.

There are also training gaps that show up later. A lot of runners avoid slow, steep trail work because it feels uncomfortable, then sign up for mountainous races. On race day, the climbs and descents expose that immediately.

Back-to-back long runs are another thing people skip. One long run a week feels like enough, but ultras stack fatigue. If you’ve never practiced running on tired legs, the final third of the race can feel like something you weren’t prepared for at all.

There’s also a mental side to this. Some runners treat the 50K like a test of toughness instead of something that requires constant adjustment. The race rewards people who pay attention, who slow down when needed, who deal with small issues early before they become bigger ones.

Ignoring everything and just pushing through sounds tough, but it usually leads to a slow shuffle or not finishing at all.

Time & terrain mismatch. Another issue that comes up a lot is expectation. People compare road times directly to trail times and assume they should be close.

I’ve had runners ask me, “I ran a 4-hour marathon, so maybe 4:10 for a 50K?”

On a flat road, maybe something like 4:30. But on trails, especially tough ones, it can be completely different.

I’ve seen strong runners, even sub-3 marathoners, take over 6 hours on mountainous 50Ks because the climbs were relentless. Terrain can easily add one, two, even three hours.

Now I always look at a course before committing to any expectations. Elevation gain, altitude, how technical the trails are—rocks, roots, all of it matters.

A 4-hour 50K might make sense on a smooth path. On a rugged mountain course, it might not even be realistic for the same runner.

A lot of men underestimate that difference. They go in expecting something close to their road pace, and the race ends up being much longer and harder than they imagined.

So yeah… knowing the course matters. And adjusting your expectations to match it matters just as much.

 What a 50K Does to a Male Body

This distance isn’t just a mental thing. It’s a full-body beatdown. I didn’t really understand that at first. Not until I went through it myself a few times, and then later actually looked into what’s going on under the surface. It’s one thing to feel wrecked after a race. It’s another to realize there are actual physiological reasons why everything starts falling apart if you’re not prepared.

Glycogen depletion & fueling. Running 50 kilometers, even at what feels like a steady, controlled pace, burns through glycogen fast. That’s your stored carbohydrate, sitting in your muscles and liver. Most men have enough glycogen for maybe two to three hours at a steady effort. After that, things start getting shaky if you’re not putting anything back in.

I remember one of my earlier ultras, somewhere around the four-hour mark, where everything just changed. My legs didn’t feel like legs anymore. More like something hollow and unreliable. My head felt foggy. Simple thoughts took effort. That’s the moment where your body has burned through most of its quick fuel and is trying to switch over to fat. And yeah, we all have plenty of fat, even the lean runners, but it doesn’t come through as fast. The energy release is slower. So what happens is you slow down, your effort feels way higher than it should, and mentally you start drifting toward “why am I doing this?”

There’s actual research behind this. Ultra runners are generally advised to take in somewhere around 150–300 calories per hour, mostly from carbohydrates . In real terms, that might be a gel every 30–40 minutes, or some chews plus sports drink over the hour. It’s not exact. Some guys can handle a lot of carbs, 60 grams an hour or more, others struggle to get even half of that down without their stomach turning.

But the worst approach is just… nothing. Or “I’ll eat when I feel like it.” I’ve tried that. It doesn’t work. I once held back on fueling because I didn’t feel hungry early on, and by halfway I was already light-headed. Now I don’t treat fueling as optional. It’s part of the run. Whether I feel like it or not.

When you keep feeding your body, even small amounts, you slow down glycogen depletion and keep your blood sugar from dropping off a cliff. And that’s usually the difference between holding pace late in the race… or turning into that slow, uneven shuffle you see everywhere in the final stretch.

Muscle damage & pacing. Another thing that creeps up on you is how much damage builds over time. It’s not always obvious in the moment, especially early on. But it accumulates.

If you’ve ever struggled to walk downstairs after a marathon, you already know the feeling. A 50K can take that and stretch it out even further. Every step, especially on trails, comes with eccentric muscle work. That’s your muscles acting like brakes, particularly your quads when you’re going downhill. Thousands of those contractions add up.

Studies on ultramarathon runners show that markers of muscle breakdown, like creatine kinase and myoglobin, rise significantly after these races . You don’t need the lab data to feel it though. I remember one mountainous 50K where the next day I literally had to walk down stairs backwards because my quads couldn’t handle the load going forward. That’s not something you forget.

Downhills are the tricky part. They feel easy on your lungs, but they’re brutal on your legs. If you go hard on those early, it feels free at the time. Later, it isn’t.

Pacing ties directly into this. If you start too fast, you recruit more fast-twitch fibers, generate more force, and basically beat your muscles up earlier than necessary. I’ve tested that on myself enough times to stop pretending otherwise. A fast start feels good for maybe 20K. Then the bill shows up around 40K.

When I hold back early, even if it feels too easy, my legs hold together longer. Not perfectly, but enough that I can still run late instead of just surviving. It’s not exciting, but it works.

Male vs female differences (briefly). People sometimes ask if men and women handle this distance differently. Physiologically, not in any dramatic way when it comes to muscle damage or fueling. Those things are more about body size, training, and individual variation.

But pacing… that’s where things get interesting. Data from larger events shows men tend to go out faster and slow down more in the second half, while women are generally more even. In marathon data, men slow down about 14% in the second half on average, women around 11% . In longer ultras, that gap gets even smaller, and in very long races women sometimes outperform men beyond extreme distances like 195 miles .

I don’t look at that as one being better than the other. It just shows how much pacing matters. And honestly, I’ve learned from it. Every time I’ve started slightly slower and stayed consistent, I’ve had a better race. The times I’ve blown up? Those were the classic mistakes. Starting like I had something to prove, then paying for it later.

Mitochondria & the aerobic engine. Underneath everything, there’s the engine. That’s really what a 50K tests.

When I first got into longer distances, I was still thinking like a shorter-distance runner. More speed work, less focus on long easy runs. It felt productive at the time. It wasn’t.

The science around endurance training points to something pretty simple. Long, easy running builds more mitochondria in your muscles. Those are the parts of the cell that produce energy. It also builds more capillaries, which help deliver oxygen to your muscles.

More of both means you can keep going longer without things breaking down.

A 50K isn’t about how fast you can run a short distance. It’s about how long you can keep moving at a steady effort without falling apart. That’s a different skill.

Over time, I had to shift how I trained. More volume. More easy miles. Longer runs that didn’t feel impressive but built something underneath.

VO₂max still matters. Lactate threshold matters. Running economy matters. But in simple terms, it comes down to this: can you keep moving at a steady pace without burning yourself out?

When you build that base, you rely more on fat for fuel at a given pace, you spare glycogen, and you don’t hit that wall as hard or as early.

It took me a while to accept that. Slowing down in training didn’t feel right at first. It felt like I wasn’t doing enough.

But over time, it changed how I handled races.

The 50K doesn’t reward the runner who can sprint. It rewards the one who can just keep going.

Training & Race Strategy for a Solid 50K Time 

So… how do you actually train for a 50K and run something in that 4–6 hour range, or whatever your goal is, without completely falling apart halfway through? This is where things get a bit less clean. There’s no perfect plan. What I’m laying out here is just what I’ve seen work, through my own mistakes, coaching others, and paying attention to what actually holds up over time.

Weekly training structure (for a sub-5h to sub-6h finish). There isn’t a one-size-fits-all plan, but there is a pattern that shows up a lot. For a reasonably trained male runner, the week usually revolves around a few key pieces that repeat over time.

The long run sits at the center of everything. That’s your anchor. Every one to two weeks, you’re building that out toward somewhere in the 20–26 mile range (32–42 km). If your race is on trails, that long run should feel like the race terrain, not just smooth roads. That’s where you learn what hours on your feet actually feel like. I’ve also split long efforts into back-to-back days before, like 18 miles on Saturday and 12 on Sunday. It’s not pretty, but it teaches you how to move when your legs are already tired. And if it’s a trail race, I’ll include hiking during those runs. Not as a fallback, but as part of the plan. Power-hiking is real. It saves you.

Then there’s the mid-week quality session. Just one. You don’t need more. That might be hill repeats or some kind of steady effort. Something like 6–8 repeats of a 3-minute hill at a hard but controlled effort, or maybe two blocks of 20 minutes at what feels like your 50K effort. Not sprinting. Not jogging. That middle ground where you can hold it, but you know you’re working. I’ve always liked doing these on rolling terrain because it feels closer to what race day actually gives you.

A medium-long run usually fits somewhere in the week as well. Maybe 90 minutes to 2 hours. Not as long as the main long run, but it adds up. It builds endurance quietly. That might fall mid-week or right after your harder session, depending on how you structure things.

Then you’ve got your easy runs filling the gaps. Shorter runs, 30 to 60 minutes. Nothing fancy. These are just there to keep things moving, build volume, and help you recover. The older I get, the easier these runs get. There’s no point turning everything into a workout.

Strength training sits in the background, but it matters more than people think. One or two sessions a week focusing on glutes, hamstrings, core, and single-leg work. Lunges, step-ups, squats, deadlifts, planks. Nothing complicated. Just building strength so your form doesn’t fall apart late in the race. I’ve skipped this before and paid for it with knee issues and tight IT bands when fatigue kicked in.

In terms of volume, a lot of recreational male runners do well peaking around 35–45 miles per week (56–72 km). If you’re pushing for a stronger time, maybe 50–70 miles (80–110 km). My best 50K results came when I was consistently sitting around 50–60 miles per week, but I’ve also run a decent race off about 40 miles per week by being consistent and specific. That’s the part people overlook. It’s not about one big week. It’s about stacking weeks together without breaking.

I like to include a dress rehearsal about four or five weeks out. Either a long run in the 25–28 mile range (40–45 km) or a tough back-to-back weekend. Not at race pace, just steady. The point is to practice everything—fueling, gear, pacing, all of it. I’ve done this before and caught issues early, like a drink mix that didn’t sit well. That’s something you want to find out in training, not halfway through your race.

Fueling & “magic Coke.” Fueling is its own skill. Before the race, I start increasing carbs a day or two out. Nothing extreme. Just leaning meals toward things like rice, potatoes, bread, fruit. I keep fiber lower the day before to avoid stomach issues, and I stay on top of hydration, especially if it’s going to be hot.

During the race, you’re looking at around 30–60 grams of carbs per hour, roughly 120–240 calories, sometimes up to 300 depending on the runner . That might come from gels, drinks, chews, or real food. Usually a mix. The key is practicing it beforehand. Race day is not the time to experiment.

Early in the race, I stick to simpler carbs. Later on, I start wanting something more solid or salty. That’s where things like small sandwiches, bananas, or potatoes come in. You listen to your body a bit, but you don’t wait until it’s too late.

And yeah… the “magic Coke” thing is real. Late in the race, a small cup of Coca-Cola can feel like a reset. Sugar plus caffeine. I remember one race where I was fading around mile 26, took in some cola, and within minutes I felt more alert, more willing to move again. It’s not magic, but in that state it feels like it.

That said, it’s not your main fuel. It’s just a boost. And caffeine needs to be tested too. It can help, but it can also mess with your stomach if you’re not used to it. I usually save it for later in the race so I don’t burn through that boost too early.

Hills, technical skills & night running. If your race has hills, you need to train on hills. Sounds obvious, but a lot of people skip it and then wonder why race day feels impossible. If you don’t have hills nearby, you fake it with a treadmill or stairs. It’s not perfect, but it helps.

Both uphill and downhill matter. Uphill teaches you how to move efficiently, sometimes by hiking. Downhill teaches your legs how to absorb impact. I’ve done hill repeats, and I’ve also spent time just hiking up and jogging down repeatedly. It’s not glamorous, but it works.

Technical terrain is another thing. Rocks, roots, uneven ground. That takes practice. Early on, I tripped a lot because I wasn’t used to it. Over time, your balance improves, your ankles get stronger, and you move more naturally over rough ground.

If your race involves darkness, you should train in the dark at least a few times. It feels different. Your depth perception changes. Everything feels slower. I’ve done early morning runs and late-night runs just to get used to that feeling. It’s not comfortable at first, but it becomes normal.

And small things matter. Like making sure your headlamp actually works. I’ve had one fade out mid-run before, and suddenly everything becomes a lot harder.

All of this adds up. Long runs, hills, fueling, strength work. It’s not about perfection. It’s about building enough experience so that when something goes wrong on race day—and something always does—you don’t panic.

Because that’s really what the training gives you. Not just fitness, but some level of calm when things start getting messy.

Coach’s Notebook

Over the years of running and coaching, I’ve built up a lot of observations. Some written down, most just stuck in my head from seeing the same patterns over and over. When it comes to men tackling 50Ks, certain things just keep repeating. Same mistakes. Same breakthroughs. Different runners, same story playing out in slightly different ways.

Patterns in male 50K runners. There are two types I keep seeing in that mid-pack range. The first one is what I think of as the pace-chaser. This guy is locked into his watch. He has a number in mind, something like 6 minutes per kilometer, and he’s going to hold it no matter what. He’ll often start right on that pace, sometimes even faster, trying to get ahead of it early.

It can work for a while. But usually somewhere around 35K, things start slipping. The pace fades, the effort spikes, and the race turns into damage control. I’ve been that runner myself. Staring at the watch, trying to force the numbers, ignoring what the course or conditions were telling me. It usually ends the same way.

The second type is what I’d call the tolerance-builder. This runner cares less about the exact pace and more about what they can sustain. They spend time building up long runs, practicing fueling, getting used to being uncomfortable for hours.

On race day, they might look slow early on. Almost too relaxed. But they keep moving, steady, and later in the race they start passing people. I’ve got a friend like this. Not the fastest guy if you look at short races, but in a 50K he’s dangerous late. He just keeps coming. His whole approach is simple—steady effort, solve problems as they show up, don’t panic.

That approach tends to work better. Not just for time, but for how the race actually feels.

Another pattern that shows up is how age changes things. Younger runners, especially in their 20s or early 30s, often come in with something to prove. They look for shortcuts. They experiment with things that promise an edge. Sometimes that’s just too much caffeine. Sometimes it goes further than that.

They’ll push early, convinced they can hold it. Sometimes they can. A lot of times they can’t.

Then you look at runners in their 40s and beyond. There’s a shift. Not always, but often. They’ve been humbled a few times. They’ve blown up before. They’ve bonked enough to know it’s coming if they don’t respect the distance.

So they pace differently. They’re more willing to walk the hills. They stay on top of fueling because they’ve learned what happens when they don’t. I see a lot of those runners finishing strong, sometimes ahead of younger guys who had more raw speed but less patience.

Experience shows up late in the race.

Mistakes I see over and over. One of the biggest ones is treating a 50K like a slightly longer marathon. Guys who’ve done road marathons assume they can follow the same training and just stretch it a bit.

That usually doesn’t go well.

Trail races, especially, demand something different. If you don’t train on similar terrain, your legs will notice. If you don’t prepare for longer time on your feet, your body will notice.

Fueling is another one. Marathoners can sometimes get through on gels alone. In a 50K, after four or five hours, that can start to fall apart. Some runners need real food. If you haven’t practiced that, race day becomes the experiment, and that’s not where you want to be figuring things out.

I made that mistake once. Grabbed pretzels at an aid station, something I had never eaten during a run before. Dry mouth, no water ready, and suddenly I’m struggling just to swallow. Had to stop and sort myself out. Small mistake, but in that moment it felt bigger than it should have been.

Another mistake is not preparing mentally for the last part of the race. I’ll ask runners, “What’s your plan for the final 10K when everything hurts?” A lot of them don’t have an answer. Or it’s just, “I’ll push through.”

That’s not really a plan.

By 40K, your head can go in strange directions. Negative thoughts, doubts, that urge to slow down more than you should. I’ve been stuck at an aid station before, longer than I needed, just because I wasn’t ready for how it would feel.

Now I break things down. One mile at a time. One aid station at a time. Sometimes even smaller than that. I remind myself that everyone else is dealing with the same thing, even if it doesn’t look like it.

I also try to simulate that feeling in training. Finishing long runs with something hard. A climb, a push when I’m already tired. Not to prove anything, just to get familiar with that state.

Another mistake that keeps showing up is assuming your marathon time translates directly to a 50K. It doesn’t, especially if terrain is involved.

I had a runner frustrated after a 7-hour 50K because his marathon time suggested something closer to 4.5. But the course had heavy climbing and technical sections. Once you factor that in, the result made sense.

Context matters more than numbers.

Coaching wins and lessons. One runner I worked with stands out. Mid-30s, busy job, had already done a 50K in 6 hours 20 minutes and felt like he could do better. When we broke it down, the same patterns were there. Went out too fast. Trained mostly on roads. Barely fueled during the race.

We didn’t change everything. Just adjusted a few things. Added one trail run per week. Some hill work. Slowed down the long runs and extended them. Practiced fueling properly, mixing gels with some real food.

Race day, the plan was simple. Start slower than he wanted to. About 15–20 seconds per kilometer slower. He didn’t like that idea at first. No one does.

But he stuck to it.

By halfway, he felt good. Then he started passing people. Stayed consistent with fueling, around 200 calories per hour. In the final 10K, he was hurting, but still running.

He finished in 5 hours 50 minutes. Under his goal, but more importantly, in control. Not just surviving.

That’s the kind of result that sticks.

I’ve had moments like that myself too. One race, I told my wife I’d be home around a certain time, maybe a bit late. I ended up much later than that. Covered in mud, completely spent, but smiling like an idiot.

Turned out I had placed in my age group. Nothing major, just a small podium, but it meant something. Not because I chased it, but because I executed well.

That day wasn’t about speed. It was about not messing it up.

And sometimes… that’s enough.

Skeptic’s Corner

Now… I love ultras. I really do. But I’m not blind to the nonsense that floats around this space either. There’s a lot of hype, a lot of half-truths, and sometimes people just repeating things that sound good without really thinking them through. So yeah, this part… this is where I step back a bit and look at things with a more skeptical eye. The stuff people don’t always want to hear, but probably should.

Terrain, elevation & reality checks. I’ve said this before, and I’ll keep saying it because people still ignore it. Comparing 50K times without context is pointless.

You’ll see questions like, “Is a 5-hour 50K good?” And honestly… that question doesn’t mean anything on its own.

Because what kind of 50K are we talking about?

Flat road, cool weather, no real obstacles? Yeah, a solid amateur might run something like 4:00 to 4:30 without being elite. Take that same runner and drop them into a mountain course, technical terrain, heat, long climbs… suddenly that same effort turns into 6, maybe 7 hours.

I’ve lived that myself. Ran a flat 50K in about 4:40 once and felt decent. Not amazing, but controlled. A few months later, did a mountain 50K and it took me 7 hours. Completely wrecked by the end. And weirdly… I was more proud of that 7-hour race.

Because I knew what it took.

So when someone throws out a fast 50K time, I always want to know more. Road or trail? How much climbing? What was the weather like?

Not to tear it down. Just to understand it.

Because otherwise, you’re comparing things that aren’t even close to the same.

Conflicting advice on taper & volume. This is another one where you’ll see completely different opinions depending on who you ask.

Some coaches say you barely need a taper for a 50K. Maybe just ease off for a week, keep your mileage fairly high so your legs don’t lose that “used to running long” feeling.

Others treat it more like a marathon. Two-week taper. Cut volume by 30–50%. Keep things light.

I’ve tried both. And honestly… neither extreme worked that well for me.

What I’ve landed on, and what I usually suggest, is somewhere in the middle. About a 10-day taper.

Two weeks out, you do your last big long run. Then you start backing off. Drop mileage to maybe 60–70% of peak in that final full week. Keep a bit of intensity—some short efforts, a few strides—just enough so your legs don’t feel dead.

Race week, you’re running, but not much. Short runs. Easy. Maybe one small session just to wake things up.

The goal is to show up feeling rested… but not flat.

I’ve seen guys go too far with tapering. They basically stop running, thinking they’re saving energy. Then race day comes and everything feels off. Heavy legs, no rhythm.

On the other side, I’ve seen people train hard right up to race week and carry fatigue into the race.

So yeah… there’s no perfect formula. You have to find what leaves you feeling right. But for most people, some kind of taper helps. Just don’t overdo it.

The “ultra on keto” and beer debates. This one always gets people going. Diet and beer. Somehow those two always show up.

First, the keto thing. Low-carb, high-fat. You’ll hear guys say it gives them steady energy, fewer stomach issues, better endurance.

And yeah, there are examples. Some runners have done really well on it.

But for every success story, there’s another one where it didn’t work at all. Guys saying they felt flat, like they had no top-end speed, like they could just grind but not actually run strong when it mattered.

From what I’ve seen—and from what the research suggests—carbs still matter. Especially when the effort picks up. Even runners who go low-carb often still take in carbs during the race.

I tried a lower-carb phase once. Didn’t suit me. Training felt harder, even though on paper it looked fine. Other people thrive on it.

So I don’t buy into the idea that keto is “the answer.” It’s just one option. Might work. Might not.

And definitely not something you try right before a race.

Then there’s beer. Because somehow beer and ultras go together.

A lot of races have it at the finish. And yeah, after hours out there, the idea of a cold beer sounds pretty good.

One beer after finishing? Usually fine. Honestly, it can feel great in that moment. Not the best recovery drink, obviously, but it’s part of the culture.

But drinking before the race… or during? That’s where things go sideways.

I remember reading about a guy who had a beer at mile 20 for the calories. Said it made the last 10K a mess. Nauseous, wobbly, everything off.

No surprise.

Alcohol messes with hydration. It messes with sleep. Both things you really don’t want to mess with before or during an ultra.

My rule’s pretty simple. Finish first. Rehydrate. Eat something real. Then, if you want, have one beer.

And yeah… I’ve learned the hard way that more than one isn’t a great idea either. Recovery takes a hit. Sleep gets weird. Next day feels worse than it needs to.

Moderation. That’s it.

 Data & Predictions 

I’m a bit of a numbers person. Not obsessive about it, but I like having a rough idea of what’s realistic going into a race.

So I’ll sometimes look at someone’s marathon time and try to estimate what that might look like for a 50K. It’s not exact. Never is. But it gives you something to work with.

Let’s say you’ve got a 3:30 marathon. That’s around 5:00 per kilometer pace. On a flat road 50K, you might be looking at something like 4:15 to 4:45.

That accounts for the extra distance and the fatigue that builds up.

Now take that same runner and put them on a trail course with some hills. Suddenly you’re looking at 5:00 to 6:00. Maybe more if it’s technical.

I’ve seen it happen plenty of times.

I had a friend who ran a 3:00 marathon. Pretty fast. He ran a flat 50K in just under 4 hours. Then did a mountain 50K and it took him 5:45.

Same runner. Very different outcomes.

Another guy I know runs around 4:00 for a marathon and usually lands somewhere between 5:30 and 6:00 in local trail 50Ks.

So yeah… the course changes everything.

When I’m planning my own races, I sometimes break things down into chunks. Like thinking in 10K segments instead of the full distance.

If I’m aiming for 5 hours, that’s roughly 1 hour per 10K. But that’s only if things were perfectly even… which they never are.

You factor in climbs, descents, terrain. Maybe the first half is faster, maybe it’s slower. Depends on the course.

I try not to stress too much if the first half isn’t exactly where I thought it would be. In trail ultras, perfect pacing is rare. What matters more is avoiding that big collapse later.

One thing I do pay attention to is calories per hour.

In one of my better races—finished in 4:48—I was consistently taking in around 250 calories per hour. My splits weren’t perfect, but they stayed fairly steady.

In a race where I struggled, I looked back and realized I had dropped to around 100 calories in the hour before things went bad. And yeah… everything fell apart right after that.

It’s not a perfect science, but you start to see patterns.

The runners who fade hard often go out too fast or don’t eat enough. The ones who stay steady usually manage both pacing and fueling pretty well.

If you like numbers, you can use simple multipliers. Take your marathon time and add maybe 5–15% for a flat 50K. More if it’s a tough course.

So a 3:30 marathon might translate to around 4:10 to 4:15 on a flat course. On trails, maybe 5:00 or more depending on difficulty.

But honestly… all of that only gets you so far.

Because eventually you’re out there, dealing with whatever the course throws at you. Mud, heat, climbs, just a bad day.

And in those moments, the numbers don’t really matter.

You just keep moving. And the clock… it ends up being whatever it ends up being.

Final Takeaway 

A 50K… it’s not just five extra miles after a marathon. It doesn’t feel like that at all. It’s a different kind of race.

Those extra miles, and everything that comes with them—terrain, time on your feet, fatigue—they expose things. Gaps in training, mistakes in fueling, even your mindset.

I’ve learned that the hard way more than once.

But that’s also why it’s worth doing.

For most men, a solid 50K finish lands somewhere between 4 and 7 hours. That range is wide for a reason. Road and trail races can feel like completely different sports.

So comparing times without context… it doesn’t really help.

What matters more is how you run your race.

Train consistently. Get used to the distance. Practice fueling. Pay attention to the small things.

And manage your ego. That part matters more than people admit.

Too much ego, and you go out too fast. You refuse to walk when you should. You push when the smart move is to hold back. And then later… it catches up.

But if you keep it in check… if you stay steady… you give yourself a chance to actually finish strong.

That’s the goal.

I’ve grown to like the 50K distance because it sits in that space where it’s hard enough to test you, but still manageable if you respect it.

You learn something every time. Usually something you didn’t expect.

So yeah… respect it. But don’t be afraid of it either.

You might surprise yourself.

And when you cross that finish line—after everything, after all those hours—it sticks with you.

Not just the time.

The whole experience.

Now let’s talk settings. Most trails don’t need your lamp on full blast the whole time. Medium brightness usually does the job. Save high-beam for technical sections. If your light has reactive settings (it adjusts automatically), that’s golden. Just don’t forget extra batteries or a backup lamp—because nothing wrecks your race faster than a dead light at 2 a.m.

And aim matters. Don’t point the beam right at your feet—it kills your reaction time. Don’t shine it too far ahead either—you’ll miss the stuff under your nose. I aim about 20 to 30 feet ahead. That gives my eyes enough warning, and my feet enough heads-up.

Foggy night? Headlamp glare will blind you. Pro move: drop the beam lower—like around your neck or use a handheld to light under the mist.

Bonus: red light mode preserves your night vision and keeps you from blinding your pacer or aid station volunteers. But red light ain’t for running. Stick to white when you’re moving fast.

One last tip: comfort counts. If your lamp strap digs into your skull after hour six, you’ll go nuts. I usually wear a Buff or a cap to cushion it.

And hey—be cool out there. If you’re passing someone, angle your light down. Nobody likes a retina blast when they’re halfway hallucinating about a talking squirrel.

Fueling When Sleepy Brain Says “Nah”

Running all night? Your body’s like, “What are we even doing, bro?” It wants to be sleeping—not chewing carbs at mile 60. That’s why so many folks crash hard after midnight.

Here’s the deal: if you’re starting to feel groggy or off, it might be low blood sugar—not just sleepiness. I’ve had those weird sleepy-bonk moments where a gel or candy perked me up within 10 minutes. Magic? No. It’s biology.

A solid tip: eat even when you’re not hungry. Set a timer if you have to. Every 30-45 minutes, toss something in your stomach. Warm broth, noodles, mashed potatoes—whatever you can stomach. That late-night “midnight snack” at the aid station? It’s not a treat—it’s a weapon. It keeps your energy steady and your mind out of the dark place.

And yeah, caffeine helps. But don’t go full espresso hammer at 10 p.m. or you’ll be jittery and puking by 2 a.m.—or wired for 12 hours and unable to sleep post-race. Instead, drip-feed it. I like a small dose every couple hours—maybe 50mg at a time. Some folks use caffeinated gels or chews—easy and effective.

Also—hydration! Just ‘cause it’s cool out doesn’t mean you get a pass. You’re still sweating, and still need to drink. Maybe not as much as in the heat of the day, but don’t slack. Dehydration sneaks up fast at night.

Struggling with nausea? Ginger ale, crackers, or a juicy orange slice can work wonders. I’ve puked, rallied, and kept moving with nothing but fizzy sugar water and a handful of pretzels. Not pretty. But it works.

When Short Naps = Time Gains

Look, I get it. Stopping to sleep mid-race feels like surrender. You’re thinking, “If I stop, I lose time.” But here’s the truth: when you’re dragging at 2 mph, stumbling like a sleep-deprived zombie, a 15-minute nap might be the smartest move you can make.

I’ve seen it firsthand—and lived it. In 100-milers that stretch over 30 hours (or the monstrous 200+ mile beasts), sleep isn’t optional. It’s a weapon. You’re either crawling through the night, micro-napping while walking (yes, it happens), or you shut down for 10–20 minutes and come back moving at 4 to 5 mph. That’s not just rest—it’s a damn time machine.

Researchers have backed this up too. Studies show that short naps improve cognitive function and reaction time—exactly what you need when your brain is melting at mile 80. I’ve taken trail naps right beside a rock, watch alarm set to 17 minutes, and boom—came out of it able to run again. Not jog. Run.

The key? Keep it short and sharp. Don’t let yourself fall into that deep-sleep black hole—you’ll wake up groggy and worse off. Set a timer or have your pacer nudge you. Hell, even five minutes with your eyes closed and legs up can reboot the system a bit.

Now, if it’s a multi-day race, yeah, you’ll need longer rest eventually—maybe an hour or two every 24 hours. But for most single-night ultras, you can gut it out with well-timed power naps and caffeine hits.

And safety—don’t mess around here. If you’re hallucinating hard, stumbling, or nearly walking off the trail, that’s your brain waving the white flag. You don’t win races by sleepwalking into a ditch.

Some runners plan ahead: “Okay, mile 75 has an aid station with cots—I’m ahead of schedule, I’ll cash in 20 minutes and finish strong.” That’s smart. And even if you don’t fully crash out, lying down for a few minutes—feet up, eyes shut—can take the edge off and lower your heart rate.

Got a pacer? Use ‘em. Talk to stay awake. Mental tasks help too—like recounting your favorite movie scene or arguing with your pacer about pineapple on pizza. Stay sharp.

 

Hallucinations: The Ultra’s Freakshow Companion

Ah, the infamous ultra hallucinations. You’re not crazy, you’re just cooked.

It’s usually night two when things start getting weird—though I’ve had people tell me they saw stuff the first night if they were pushing too hard. I once saw a couch in the woods. Spoiler: there was no couch.

According to studies and ultra lore, your tired brain starts filling in blanks—tree stumps become animals, rocks look like people, and twinkling lights in the valley trick you into thinking you’re almost at an aid station (you’re not).

It’s just brain static. One runner told me, “The first time, it freaked me out. Now, I just wave at the hallucinations and keep moving.” Legendary.

Best move? Acknowledge it. Laugh at it. Don’t give it power. If you’re seeing ghost puppies, thank them and carry on (seriously—Doug Mayer did that).

But if stuff gets creepy or starts pulling you off course, time to act. Low blood sugar and dehydration can make things worse, so fuel up. And if it gets really bad? A 20-minute nap often clears the fog.

Another trick: don’t go looking for hallucinations. If you start ghost-hunting in your brain, you’ll find ghosts. Keep your eyes moving, stay alert, and—if you’ve got a pacer—lean on them. They’ll call BS when you point at a “row of houses” in the forest.

Running solo? Talk or sing to yourself. Stay grounded. And if it really rattles you, sit down, drink water, breathe. Reset. Music can help too—distract your brain from creepy sounds in the woods.

Only worry if it’s leading you to danger—like trying to shortcut through a bush that looks like a road. That’s your signal: get help, get rest.

As I like to say: “When you start seeing things, congrats—you’ve made it deep into the pain cave. Just don’t let the furniture eat you.”

Daylight God, Midnight Ghost

Ultras are weird, man. One moment you’re flying high, feeling like a trail god—sun on your back, legs strong, grinning like a maniac. Then 2 a.m. hits and bam: you’re a ghost.

That contrast is brutal. Day one, you’re waving to volunteers and soaking in the scenery. By nightfall, you’re a shadow—cold, invisible, barely hanging on. That’s the beauty and the beatdown of ultras. You live five lives in one race.

Here’s what I always tell my runners: both the god-mode and ghost-mode are illusions. When you feel like a superhero—don’t go full send and blow up. Respect the course. And when you feel like quitting at mile 85 in the dark? Hold on. The sun’s coming.

There’s something magical about that pre-dawn rebirth. Birds chirping. Sky lightening. It’s like someone flipped a switch in your brain. You’re back. You can run again.

That sunrise? It’s saved a lot of finishes. Just knowing it’s coming can get you through the darkest miles.

So if you’re out there, mid-race, cold, lonely, and half-asleep—hang tight. You’ll be a god again by morning.

People love to joke that ultras are “90% mental.” I think that undersells it.

Because out there — when your legs are trashed, your stomach hates you, and everything hurts in that dull, all-over way — your mind isn’t just part of the race. It is the race.

I’ve had moments deep in ultras where my body felt completely wrecked… and then, somehow, an hour later I was moving smoothly again, like someone flipped a switch. Same legs. Same blisters. Same fatigue. Different headspace.

That’s the weird, beautiful, terrifying thing about ultras: how fast things can change.

One minute you’re convinced you’re done. The next you’re running downhill, grinning, wondering what the hell you were so dramatic about.

The runners who finish aren’t the ones who never hit those lows. They’re the ones who learn how to sit with them without panicking. Who don’t believe every dark thought just because it shows up loud and convincing.

This section isn’t about being “mentally tough” in some chest-thumping way. It’s about learning how to ride the waves — how to break the race down, calm your nervous system, reset your brain when it spirals, and delay quitting long enough for the fog to lift.

Because in ultras, the mind quits first… and it also comes back online way faster than you think.

If you can learn to work with that — instead of fighting it — you give yourself a massive edge when the race really starts.

Break the Beast Into Chunks (Like a Real Coach Does)

Here’s the deal—standing at the start of a 100-miler and thinking “I gotta run 100 miles” is like standing at the base of Everest and saying “I’m just gonna jump to the top.”

Nope.

That’s a meltdown waiting to happen. So, break it down. Segment it. This mental trick is a game-changer. Ten-hour race? Cool. That’s ten mini races. Get through one, reset, and go again.

Personally, I like to chunk ultras by aid stations.

That’s how I coach folks too. Say the next one’s 8 miles away? That’s the only race I care about in that moment. Forget mile 92—we’re not there yet.

I’ve had athletes frame a 50-miler as five 10-mile blocks. Some go by terrain: “Climb the hill (Block 1), cruise the downhill (Block 2), survive the flats (Block 3),” and so on.

One study in the Journal of Strength & Conditioning Research actually backs this up—breaking a big challenge into smaller chunks keeps your brain from going into panic mode.

Think of it like this: it’s easier to run 1 mile 100 times than to run 100 miles once—at least for your brain.

Top runners get this. At mile 50, they stop looking ahead and start counting down. Some reset completely every few hours—like starting a fresh race. And when you’re deep in the suck, even saying “just get to that tree” works.

I’ve used landmarks, songs, and even the idea of a cold Coke at the next station. Trust me—when your legs are toast, your brain needs breadcrumbs to follow.

The Toolbox: Mantras, Breathing, and Head Games

Ultras mess with your head. That’s why you need mental gear just like you need shoes and gels. I call it the “toolbox”—the tricks that keep you from unraveling when the wheels fall off.

Mantras: Little Words, Big Punch

These are tiny phrases that keep you moving when everything says stop. My go-tos? “Keep grinding.” “Strong body, stronger mind.” And sometimes just “relentless.” One time, I ran an entire loop just repeating “One more step” out loud like a crazy person—and it worked.

Pick a mantra that means something to you. Make it yours. Scott Jurek once used “Sometimes you just do things”—simple, weird, but powerfully Zen. Humor helps too—say something ridiculous if it breaks the tension. I’ve even muttered “Don’t puke, don’t puke” on steep climbs. (Spoiler: I puked.)

Breathwork: Calm the Chaos

When your heart’s racing and you’re on the verge of freaking out, go back to the breath. Inhale for three steps, exhale for three. It’s like a metronome for your brain. I’ve used this during climbs when my legs were jelly and my chest was thumping like a jackhammer. Slow breath = calm mind.

Deep belly breaths also help with nausea or that spinny, out-of-body feeling you sometimes get late in races. You’re basically telling your body, “We’re good. Chill.”

Visual Anchors: Mind Movies That Work

Visualization isn’t just for pre-race prep—it can work mid-race too. I’ve imagined I was just running to meet a buddy at the park instead of dying at mile 70. I’ve pictured finishing strong so many times in training that, during races, I know the finish line in my mind before I ever see it.

Pro runner Devon Yanko has a cool tactic: she gives each race loop a theme. No music on loop one, tunes for loop two, pacer magic on loop three. That kind of mental shift can freshen the brain when the legs can’t carry the load alone.

I’ve even given myself “missions”—like “On this stretch, count how many squirrels you see.” Sounds goofy? Maybe. But it works. It keeps you from spiraling into “I hurt, this sucks, why am I doing this?” mode.

The Bonk

Look, if you’re toeing the line at an ultra, you’re going to bonk. That’s not a maybe. It’s a “when.” I don’t care how dialed your training was or how clean your nutrition plan looked on paper—at some point, your body’s going to slap you with that low-battery warning. That’s the bonk. It’s not the end—it’s the cover charge.

Unlike in a marathon where a bonk can nuke your PR dreams, in ultras, it’s more like a mid-race gut check. A lot of the time, it’s just your blood sugar flatlining. You fix that with fuel. Doesn’t matter if your stomach’s being a diva—get some sugar and salt down. Gels, Coke, gummy worms—whatever you can keep down. Then give it 10, maybe 15 minutes. Boom—zombie runner turns human again. Seen it happen hundreds of times. Lived it, too.

I’ve watched runners crawling at mile 50 come back swinging at mile 55 after a hit of soda and some salty chips. One dude I coached bonked so hard at mile 62, he sat on a rock talking nonsense—but 20 minutes later he was passing people like nothing happened. That’s the game.

It’s Supposed to Suck 

You don’t get to mile 70 without flirting with some darkness. And that voice in your head whispering, “This hurts, maybe you should stop”? Yeah, that guy’s gonna get loud. But he’s not the boss. He’s just scared.

Ultrarunners have a few mantras for these moments. My favorite: “It’s gonna hurt no matter what, so I might as well keep going.” Another gem: “This too shall pass.” You start to expect the suck. And once you expect it, it loses its bite.

Some runners even laugh when everything starts falling apart. Gallows humor, man. One time I was hobbling through mile 78 with a blister the size of a grape and I just started cackling. Why? Because I knew I was earning something. You don’t get that kind of grit without wading through some pain.

Your Mind Will Quit First — But It’ll Also Reboot Fast

Here’s the crazy part: the mind breaks before the body. That’s backed up by research too. The “central governor theory” says the brain pulls the emergency brake way before your legs are actually toast. So when your brain screams “I’m done,” your body still has miles in the tank.

And the flip side? The mind also rebounds faster. I’ve had mental breakdowns at mile 40, thinking there’s no way I can keep going—then 30 minutes later, I’m chasing the sunrise at mile 50 feeling reborn. It’s wild. One bad hour doesn’t mean the day’s over. Ride the wave.

If you’re stuck in the suck, don’t treat that voice like gospel. Instead, tell yourself: “Let’s reassess at the next aid station.” Often by then, things have shifted. Sun’s out. Legs warm up. You find rhythm again. That “I want to quit” moment? Just a speed bump.

DNFs Aren’t the End — They’re Training in Disguise

Let’s be real. Sometimes, you’ll pull the plug. DNF (Did Not Finish). Feels like a gut punch. But guess what? Most of my runners who crush their next big ultra do it on the back of a DNF. Those “failures” teach you more than smooth finishes ever will.

Maybe you blew up your pacing. Maybe you didn’t eat enough. Maybe your reason for running wasn’t strong enough that day. It’s all info. And next time, you show up smarter—and hungrier.

I had a brutal DNF at my first 100K. Missed a key fueling window, cramped so hard I thought both hamstrings exploded. But the next race? I nailed every checkpoint. Because pain taught me what spreadsheets couldn’t.

Ride the Lows, Surf the Highs

This is the paradox of ultrarunning. Your brain’s gonna fold long before your quads give out. But that same brain can be coaxed back in—faster than you think. Sit for five minutes. Eat something. Watch the sunrise. You can go from “I’m done” to “Let’s go” in less than a mile.

So when you first think, “I’m quitting,” don’t act on it. Bargain with your brain. Say, “Okay, we’ll check again in 20 minutes.” Half the time, by the next aid station, you’re a new runner. That’s the trick—stretching the space between “I want to quit” and “I’m actually stopping.”

Every time you push through that moment, you build the mental calluses that make you tougher next time. That’s how you grow. That’s how you earn it.

Ultras don’t reward “perfect plans.”

They reward problem-solvers.

Because no matter how fit you are… no matter how dialed your training is… at some point in an ultra, something is going to go wrong. That’s not negativity — that’s just the sport.

Your stomach will do something weird.

Your gear will betray you.

Your quads will start filing complaints.

Your brain will get dramatic at 3 a.m. and start pitching the idea of a nap in a ditch like it’s a luxury resort.

And the most dangerous part? None of this feels like a “small issue” while you’re in it. Everything feels like the end of the race. Everything feels urgent.

That’s why the best ultrarunners aren’t the ones who avoid problems — they’re the ones who stay calm when the chaos shows up.

I’ll never forget seeing a guy duct-taping his shoe mid-race with a grin on his face, like it was just part of the course.

He looked at me and said something like:
“Ultras aren’t about avoiding problems — they’re about solving them while still moving forward.”

That hit me. Because it’s true.

So this article is your “what now?” guide.

• What to do when your gut turns on you.
• How to handle cramps without turning it into a full-blown emergency.
• How to deal with gear fails, wrong turns, and that downhill death march.
• And how to tell the difference between normal suffering… and the kind of warning sign you don’t mess with.

Let’s get to it…

Gut Bombs, Cramp City & That Lovely Puke Moment

Your stomach is gonna take a beating. You’re pushing food, sugar, salt, and fluids into a system that’s running a marathon every few hours—sometimes at altitude, often in heat. It’s a mess down there.

Feeling nauseous? First thing: back off the gas. Drop your pace, let that heart rate chill. Most times, the gut freak-out is because you’re going too hard or eating too much too fast.

Here’s what I keep in my vest when I feel the nausea creeping:

• Ginger chews or candied ginger (a lifesaver)
• Saltines or pretzels—bland, but they work
• A couple of Tums (yep, old-school, but magic for minor acid reflux)

If you feel like you’re gonna hurl, guess what? Let it fly. Seriously. I’ve coached runners who puke at mile 40, rinse their mouth, sip water, and finish strong. It’s like hitting reset on your system. One study even showed that mild vomiting can improve perceived exertion afterward. Weird, right?

But—if you can’t keep anything down for hours, that’s a red flag. Dehydration is creeping in. You need to stop, sip broth, chew some ice if they have it, and regroup.

Cramping? Stretch if you can, but don’t force it. Walking it off often works better. Salt tabs, pickle juice, or even a shot of mustard (I know, gross) can shut cramps down fast. There’s research behind this—pickle juice’s vinegar triggers a nerve reflex that tells the cramp to knock it off.

Pro tip: If you start feeling both nausea and cramps, think low sodium. That’s your clue to get broth or salt-heavy snacks in ASAP.

Gear Fails, Getting Lost, and the Downhill Death March

Stuff breaks. Be ready to improvise.

• Shoelace snaps? Tie it off or pin it with your race bib safety pin.
• Sole peeling off? Wrap it in duct tape—carry some around your pole or water bottle.
• Bladder leaks? Switch to bottles if you can, or ask around at aid. There’s always someone with extra gear or batteries.

One time, my headlamp died on a mountain pass. No moonlight. I stumbled upon a bunch of campers who gave me their backup batteries. 

Take a wrong turn? Welcome to ultrarunning. If you haven’t seen a marker in 10-15 minutes, stop and think. Don’t go further hoping it’s right—backtrack to the last flag. It sucks, but it beats adding miles to an already brutal course.

I always say: “No wrong turns, just scenic detours.” Keeps the panic away.

Quads destroyed? Oh yeah, that happens. Especially if you didn’t train enough downhill. If every descent feels like a crime against your legs, shift your focus:

• Use poles if you’ve got ‘em
• Take shorter steps—think baby shuffle
• Hike the downhills if needed
• Sometimes salt and calories help spark the legs again

Next time, train the descents. But in the race? Survive the downhill and save your fight for the flats.

Emotional Spirals & Mental Freakouts

Let’s talk about the mental demons. You’re 9 hours in, nothing feels good, and you start asking:

“Why am I even doing this?”

Totally normal. I’ve cried on trail. I’ve been pissed at trees. I’ve cursed at rocks. But you can’t quit at your lowest moment. That’s the rule.

If you’re melting down:

• Cry. Seriously, let it rip. Then keep moving.
• Give yourself a countdown—“Okay, I can sulk ‘til the next tree, then game face on.”
• Dedicate the next mile to someone who can’t run, or who got you into this crazy sport

One of my mantras when it gets dark (literally or mentally):

“This is the part I paid for—the pain, the test, the moment I find out what I’m made of.”

It works. Flip the script. Make the suffering meaningful.

When to Drop—and When to Dig Deep

Let’s be real—sometimes you gotta DNF.

It’s not weakness, it’s wisdom.

I’ve been there. Limping on a jacked-up tendon isn’t “tough”—it’s begging for months on the injured list.

If you’re showing real signs of heat stroke (like confusion or you stop sweating), or your lungs are feeling funny from hyponatremia, or maybe you flat-out missed the cut-off time—then yeah, it’s time to call it. That’s not quitting. That’s survival. You live to run again.

And hey, life hits too—maybe your crew’s down sick, or you’re stuck waiting for help. That’s just how ultras roll.

But here’s the truth most runners won’t admit out loud: usually, when you feel like quitting… your body still has gas in the tank. It’s your brain screaming louder than your legs.

That’s where the magic happens—knowing the difference between the kind of pain you push through, and the kind you absolutely don’t mess with.

• Good pain? That’s fatigue, sore muscles, blisters yelling at you—hurts like hell, but won’t take you out of the game. You’ll wake up sore, not sidelined.
• Bad pain? That’s sharp, stabbing stuff. It’s getting worse the longer you move. It changes how you run. You start limping weird, maybe your knee locks up or that ankle blowout starts screaming louder each mile. That’s your body waving a red flag.

One time I rolled my ankle on a trail—it ballooned up like a grapefruit. Tried jogging it off… didn’t work. Another runner had what looked like the same injury and still finished. That’s the thing—it’s personal. Know your body.

If you’re dizzy, can’t focus, or feeling chest pain? Stop. Sit. Talk to medical. That’s a no-brainer.

But if you’re just crushed and everything feels impossible? That’s often the storm before the breakthrough. Fuel up. Walk it out. I’ve had death-march moments turn into finish-line sprints (well, maybe slow shuffles… but you get me).

And race med staff? They’re there for a reason. Let ‘em check your vitals—blood pressure, hydration levels, the whole nine. If they say you’re done, trust ‘em. That’s not weakness—it’s being smart.

Now, if you’re still safe and upright, ask yourself: What’s my “why” for this race? If finishing means everything—and I mean everything—dig deep. It might be slow. It might be ugly. But you can still get there.

But if finishing now means you’ll miss a key race next month due to injury? Maybe pulling the plug is the power move. Strategic, not soft.

Every ultra-runner has a DNF somewhere on their record. It’s a rite of passage, not a scarlet letter. But before you throw in the towel mid-race, ask this: “Will I regret this tomorrow?” If the answer’s even close to yes—keep moving. Delay the decision. Give it another aid station.

I love this saying: “It’s okay to want to quit. It’s not okay to quit unless they pull you or you’re broken.” That’s intense, but there’s truth in it.

And if you do DNF? Don’t bury it—break it down. Why’d it happen? Fix it. Come back meaner and smarter. That’s how you turn a DNF into a PR next season.

You can run a marathon and feel like you’ve conquered the world.

You can run an ultra and realize the world is bigger, wilder, and tougher than you ever imagined.

This isn’t just “a little longer than 26.2.” Ultras are a different animal—part survival test, part eating contest, part mental war you fight in the dark with sore feet and a stubborn heart.

You’ll walk when it’s smart, run when it’s possible, and hurt the entire time. And you’ll love it.

In a road race, the clock is your enemy.

In an ultra, it’s your partner—you just need to keep moving until you run out of it.

There’s no hiding from the terrain, the weather, or the doubts.

But with the right training, gear, fueling, and mindset, you’ll not only finish—you’ll own the trail.

This guide? It’s the ultramarathon blueprint. Everything from your first 50K to your first 100-miler, with the gear, fueling, and mental grit it takes to go the distance.

What Makes Ultras Different 

Let’s be clear: ultras aren’t just longer marathons—they’re a whole different beast.

In a road marathon, you’re glued to your splits, obsessed with shaving 10 seconds off your pace.

In ultras? Toss that mindset out. Success is about staying upright and moving. For hours. Sometimes days.

It’s not about speed. It’s about staying in the game.

You’ll walk hills—on purpose. Even front runners do it. You’ll shuffle flats, stumble downhills, maybe curse every root and rock.

That’s not failure. That’s strategy.

You learn quick that conserving energy is the name of the game, and walking isn’t weakness—it’s survival.

In road races, walking feels like giving up.

In ultras, it’s a power move. You’re in it for the long haul, not the highlight reel.

You’re not racing your last 5K split—you’re racing your ability to keep going when everything else says “Stop.”

Terrain, Sleep, Weather: Pain from All Angles

You ever go from sunburn to frostbite in the same race? Ultra runners have.

In a road marathon, the course is flat-ish, the weather’s a factor, but not the villain.

In trail ultras, everything is the villain. The ground fights you—roots, rocks, switchbacks that never end. You bake under exposed ridges at noon, then freeze your butt off on a mountain at 2 a.m.

Take Western States 100. You can roast in 100°F canyon heat by day and then shiver with hypothermia by night.

The course wants to break you.

The sleep deprivation? That’s real too.

After 20+ hours awake and moving, your brain starts doing weird things.

One study said about a third of runners in multi-day events hallucinate. Trust me, I’ve seen it, and it wasn’t’ “there”.

It’s not just your legs. It’s your feet swelling until your shoes feel two sizes too small.

Your shoulders ache from your hydration pack.

Your stomach? Probably staging a rebellion.

Blisters, chafing, sunburn, nausea—ultras aren’t about avoiding pain.

They’re about learning to run with it.

I’m drawing a really dark picture of ultra racing, but bear with me…there’s is light down the tunnel.

 

Breaking Down Ultra Distances (a.k.a. Where Pain Gets Creative)

Let’s get one thing straight: not all ultras are cut from the same cloth.

A 50K ain’t just “a little longer than a marathon,” and a 100K isn’t just a pit stop on the way to 100 miles.

Every distance brings its own flavor of hell — and sometimes it’s the middle ones that mess with your head the most.

The 50K Trap: “Only” 5 More Miles… Until It Breaks You

On paper, 50K sounds chill — just 5 more miles than a marathon.

How bad could it be? Here’s the trap: a lot of runners come in with marathon brain, thinking they’ll just hold their usual pace a bit longer.

But those extra miles? They hit different.

By mile 26, you’re usually hanging on for dear life, and then boom — you’ve still got 5 more miles of hills, mud, and trail tantrums.

On my first 50K race (Bromo desert race), I hit a pain I didn’t even know existed at mile 19. I couldn’t even walk up the hills. – and most the course was hilly.

Why? Because many 50Ks are on trails with serious elevation. They’re slower. They demand more patience.

And if you don’t respect the terrain — if you treat it like “marathon-plus” — you’ll learn humility real quick in the last 90 minutes.

Why 100K Hurts in All the Wrong Ways

Here’s a truth bomb that throws a wrench into the ultra logic: some runners say the 100K is worse than 100 miles.

Yeah, I said it.

How can 62 miles suck more than 100?

One word: pace.

In a 100 miler, you know it’s going to be a death march at some point.

So you settle into a slow grind early. But 100K? It’s short enough that people push harder. They think, “I can race this.” And that mindset wrecks people.

You hit mile 40 thinking you’ve got this, and then suddenly your legs are junk and your brain is asking, “Why didn’t we slow the hell down earlier?”

Let me break it down for you in simple words: Running a flat 100K in under 8 hours hurts way more than pounding a 100 miler in 30.

That’s the truth. One’s intensity; the other’s endurance.

Plus, 100K is a weird mind game. You might finish near sunrise, sick and shattered, and think, “I still would’ve had 40 miles left in a 100-miler.

What the hell?”

You go through the dark night of the soul, but don’t get the full glory of 100 miles. It’s a mental trap — not long enough to slow down, not short enough to stay sharp.

Stage Races: Fatigue Stacked on Fatigue

Think ultras are rough? Try doing them back-to-back-to-back on trashed legs.

Stage races — like Marathon des Sables (6 days through the Sahara) or multi-day 200 milers — are their own beast.

You run a ton each day, then wake up and do it again.

And again.

And again.

There’s no “recover fully and bounce back” here. You’re constantly just a little more wrecked than the day before.

That hot spot on your heel from day 1? Now it’s a deep, oozing blister by day 4.

Those sore quads? Now they feel like meat tenderized by a mallet. You’re chasing recovery that never comes.

Research even backs this up: multi-day ultras cause more long-term muscle damage than doing the same mileage in one go.

Why? Because the body never gets a full break. You’re layering damage on damage.

And mentally? It’s war. Every morning you drag yourself out of a warm sleeping bag, slide on crusty socks, and convince your brain that yes, we are doing this again today.

The upside? You get sleep. And camp camaraderie is real. Misery loves company, and swapping stories by the fire each night helps you forget how much your legs hate you.

Timed Ultras: Racing the Clock, Not the Course

Let’s talk about a different kind of sufferfest: timed races.

We’re not talking 50Ks or 100-milers with a finish line waiting to hug you.

This is about chasing time, not distance—6-hour, 12-hour, 24-hour, even multi-day ultras where the goal is simple (and savage): run as far as you can before the clock hits zero.

No banner. No big finish chute. Just you and the seconds ticking away.

I’ll be real—this format messes with your head. You can’t DNF unless you completely stop, which sounds freeing, right?

But there’s a dark side: the urge to quit once you’ve hit a “good enough” number is brutal.

Because there’s no official end—you decide when it ends. The mind games? Next level.

And don’t get me started on the loops.

Most timed events are on short courses—think one-mile loops or even 400m tracks. Yeah, you read that right.

Top runners break the day into chunks. One hour at a time. Mini-goals. Crew check-ins. Reset the mind often. Almost like meditation with blisters.

Trail-Specific Beatdowns: Welcome to the Jungle

Take a seasoned road marathoner, put them on a gnarly mountain trail, and they’ll look like Bambi on ice.

Trail ultras don’t play nice. They come with a grab bag of chaos: rocks, roots, rain, mud, 5,000 ft climbs, mystery descents, and maybe a few hallucinations thrown in. It’s not just about going longer—it’s about running smarter, rougher, and more aware.

Lemme explain more…

Technical Terrain = Welcome to Muscle Confusion

On the road, you repeat the same motion over and over.

On trails? You’re side-stepping roots, leaping puddles, sliding on scree, and trying not to face-plant into a pinecone.

Your stabilizers—hips, glutes, ankles—go into overdrive.

Most roadies are sore in muscles they didn’t even know they had after a single trail run.

I’ve seen 2:45 marathoners humbled by a 50K with rocks and 6,000 feet of climbing.

Pure speed won’t save you if your ankles can’t handle cambered trail or your brain can’t handle 10 hours of constant focus.

Trails Demand Your Full Attention

One second of zoning out? Bam. You’re kissing dirt.

Technical trails force you to stay in the moment. Every step has to be deliberate.

That mental fatigue? It hits way before your legs give out.

That’s why trail runners train not just their bodies, but their footwork and reaction time.

Downhills Will Torch You

On the road, you cruise downhill. On trails, it’s breakdancing while trying not to die. If you go timid, you brake every step—and destroy your quads. Go too bold, and your risk of eating rock skyrockets. It’s a fine line.

Want to master descents? Practice. Develop that flow. Trail running isn’t just running—it’s trail skill, and it takes time to build.

---

Training for the Pain Cave

Let’s be real—trail ultras are a different beast. You’re not just jogging through the woods. You’re climbing thousands of feet, bombing down sketchy descents, dodging roots and rocks, sometimes in the middle of the night. Road PRs don’t matter out here. The trail doesn’t care about your 5K split—it wants to chew you up and spit you out.

But if you train smart and respect the mountains, you can learn to thrive out there. Here’s what it takes.

---

Vert Training & “Quad-Proofing” for the Downhills

Climbing is hard, sure—but it’s the downhills that’ll wreck you.

I’ve had races where I flew up the uphill portion only to get reduced to a stiff-legged shuffle on the way down.

Why? It’s those brutal eccentric contractions—your muscles lengthening while under load, especially in the quads.

That’s the kind of damage that turns your legs into “moldy jello” (actual coach quote I’ll never forget).

And it’s not just soreness. A review in the European Journal of Physiology showed that downhill running causes “severe lower limb tissue damage,” with blood markers of muscle breakdown spiking like crazy.

You don’t want to learn this the hard way at mile 42.

Here’s the fix: train for it. You’ve got to earn your downhill legs.

Do descents in training. S

tart with mild grades, then hit the steep stuff. Your quads will scream at first—but here’s the magic: your body adapts.

It’s called the “repeated bout effect,” and it means your legs get tougher the more they face that kind of load.

Mix in strength work too—hammer those quads, glutes, and calves.

Squats, lunges, step-downs. Trail runners aren’t just runners—we’re mountain athletes.

A few other tricks:

• Trekking poles help share the load on long descents (especially late in a race).
• Cushioned shoes or rockered soles can ease some of the impact.
• But at the end of the day? You’ve gotta build the calluses. Nothing replaces leg time on real descents.

Miss your vert training, and the trail will punish you for it.

Weather Mayhem: It’s Coming for You

One minute it’s foggy and chilly, the next you’re baking under the sun on an exposed ridge, then BOOM—hailstorm.

Welcome to the world of trail ultras.

Out here, weather is chaos, and it doesn’t care if you’re 20 miles from the nearest aid station.

I’ve started races in freezing rain and ended them dehydrated in 90°F canyon heat. Some events—like UTMB or Western States—are notorious for throwing every season at you in 24 hours.

It’s not about if the weather turns, it’s when.

Here’s is my golden rule for ultra survival: pack like your life depends on it—because sometimes, it does.

• Lightweight waterproof jacket? Always in the vest.
• Gloves, buff, dry socks? Do it.
• That extra layer you hope you won’t need? You probably will at 3 a.m. on some cold mountain pass.

Western States warns runners about “extremes of heat and cold” for good reason.

Hypothermia and heat stroke are very real. I’ve seen people wrapped in space blankets shivering their soul out at mile 70. Don’t be that guy. Gear up.

 

Getting Lost Sucks – Learn Navigation

Trail ultras don’t have neon arrows or cheering crowds every quarter mile.

You’re in the woods, and those tiny course flags? Easy to miss, especially in the dark or when your brain is mush at mile 45.

Learn to navigate.

• Practice reading course markings.
• Know how to use your GPS watch or a map.
• Always carry a headlamp—even if you think you’ll finish before dark. (Ask the guy who turned a 50K into a 90K survival hike in Canada when he got lost for 10 hours with no light.)

That story’s not an exaggeration. That runner got lucky. Don’t count on luck.

Bring a whistle, emergency layer, and the mindset that you are responsible for yourself out there. This is not a road race where medical is a few blocks away. You’ve got to be your own safety net.

I’ve written a guide on how to avoid getting lost on the trails. Check it out here.

Gear Weight: The Trail Tax

Unlike road races where you show up with shoes and good vibes, trail ultras mean carrying gear. And it adds up fast—pack, water, snacks, poles, jacket, first aid, etc. You’ll feel it in your shoulders, lower back, and stride.

Train with your gear. Wear your vest on long runs. Figure out where it rubs. Dial in where stuff goes. Water bottle bouncing off your ribs at mile 20 is not fun.

Drop bag tip: Think ahead. Pack by time of day, not just mileage.

• Expect to hit mile 50 around sunset? That’s where your headlamp goes.
• Climbing a monster hill after that? Poles go in that bag too.
• Changing shoes or socks? Plan it. Practice it. Label everything.

Every single item you plan to race with should be tested—hard—in training.

That includes your headlamp (can you change batteries with frozen fingers at 2 a.m.?) and your socks (blisters will eat your soul if you don’t get this right).

Nothing new on race day. Ever.

The Trail Don’t Care About Your VO2 Max

Here’s the truth a lot of roadies find out the hard way: running skill means jack if your ankles roll on the first rock, or you freeze up when you lose the trail.

Trail ultras are survival events. You need:

• Strong legs.
• Tough feet.
• Mental flexibility.
• A deep well of grit.

The fastest 10K runner might still DNF because they blew out their quads or melted down in the dark. The trail is the great equalizer. It rewards preparation, adaptability, and pain tolerance more than top-end speed.

Be smart. Be tough. Be ready.

From Marathoner to Ultrarunner: Here’s Your Wake-Up Call

So you’ve crushed a few marathons and now you’re eyeing the big leagues — 50Ks, 100Ks, maybe even a 100-miler.

Respect. But listen close: if you bring your marathon brain into an ultra, it’ll chew you up and spit you out by mile 30.

Ultras are a different beast. It’s not just about stretching your long run.

It’s about retraining your head, your legs, and maybe most importantly, your ego.

Let’s rewire your mindset.

---

Why Marathon Pace Will Wreck You in an Ultra

Marathoners are pace-obsessed.

I get it.

You spend months chasing that perfect split — tempo at X:XX, intervals at Y:YY, long runs at MP+20 seconds.

That kind of structure works great when you’re running on smooth pavement for 26.2 miles.

But in ultras? Throw it out.

Trail ultras laugh at your pace charts. Your mile splits will swing like a yo-yo — one minute you’re cruising an 8-minute downhill, the next you’re crawling a 20-minute uphill that feels like death.

If you’re locked into marathon pacing, you’ll crash hard and early.

Ultra veterans — and smart coaches — say it straight: train by effort, not pace. Use RPE or heart rate. Trust your gut, your breath, your legs. Not your Garmin.

And stop avoiding slow running. I’ve coached plenty of fast marathoners who felt “wrong” running at 12:00/mile on trails.

Newsflash: that’s normal in ultras. And necessary. Slower doesn’t mean weaker — it means smarter. It means you’re playing the long game.

Want to prep for ultras? Add this to your playbook:

• Practice walking (yeah, we’ll talk more about that).
• Do long, slow runs — like, glacial slow.
• Stop checking your splits and start listening to your body.

This ain’t a speed test. It’s an endurance war.

Building Your Base for Ultra

Let’s talk about the long game. Whether you’re coming from the 10K world, marathons, or you’re brand-new to endurance running, here’s what you need to know:

You can’t fake your way through an ultra.

Not a 50K.

Definitely not a 100-miler.

You need a base. A real one.

We’re talking 3 to 6 months of steady, mostly easy running—before you even start your official training plan.

This is where you build the engine. No shortcuts.

This phase is less about speed and more about consistency.

It’s the slow grind that strengthens your tendons, builds aerobic capacity, and teaches your body how to burn fat efficiently. This is what lets you finish the race later.

Ballpark Weekly Mileage Goals:

• Training for a 50K? Work up to a consistent ~30 miles/week.
• 50-miler? Around ~40 miles/week.
• 100-miler? ~50–70 miles/week during peak base-building.

And before you panic: these aren’t strict rules.

Every runner’s different. I’ve coached ultra runners who peaked at 45 miles/week and still finished the course unscathed—because they trained smart, rested well, and didn’t get greedy with the numbers.

During base phase:

• Focus on frequency: 5–6 runs/week if possible.
• Prioritize time on feet over pace.
• Consider two-a-days (doubles) to boost volume without hammering one long run.
• Mix in hiking if you’re training for hilly terrain. Hiking builds strength and endurance without the impact.

This base phase builds your “chassis”—the structural strength that will carry you through the hellish miles later on.

---

Hike Like Your Race Depends on It

Let me give it to you straight: hiking isn’t just something you do when you’re too tired to run—it’s your ultra training cheat code.

If you’re eyeing a trail ultra, you better start respecting the hike.

I’m talking long, sweaty, leg-burning climbs where your glutes scream and your calves wake up to the reality of vertical gain. That’s not “wasted” time—it’s money in the endurance bank.

Here’s why hiking works really well:

• Low-impact strength builder: Power hiking hits your hips, glutes, and calves hard—but without the pounding of a long run. You’re still grinding, just smarter.
• High aerobic payoff: Push the pace on an incline and your heart rate climbs fast. It’s like stealth cardio.
• It’s race-specific: Newsflash—you’re gonna hike in an ultra. A lot. Training for that is just common sense.

In other words: Hiking is more sustainable than running, and it builds the same kind of fitness—just with less damage.

Long Hikes Count (Seriously)

You don’t need to run 30 miles to build base. A 4-hour mountain hike with a pack? That’ll make you tougher than any treadmill session. It’s not just physical—it trains your head to stay locked in when hours tick by and the trail doesn’t care how tired you are.

Even some of the Euro elites—Kilian freakin’ Jornet included—do hiking-only sessions. If it’s good enough for Kilian, it’s good enough for us.

The Math Adds Up

If you can take your hiking pace from 20 minutes per mile to 15–16 minutes per mile on steep grades, you could save hours on race day.

HOURS.

And the best part? Hiking adds variety. It saves your joints, toughens your feet, and breaks the running-only grind that wrecks so many bodies during base season.

 So don’t just “fit in” hikes—schedule them.

Do vert hikes.

Do treadmill incline walks. Do hill rucks with a pack. Treat them like gold.

That power-hiking beast flying past runners late in the race? That can be you.

---

Back-to-Backs 

Alright, now we’re getting into the juicy stuff: back-to-back long runs—aka the most misunderstood weapon in the ultrarunning world.

These are the cornerstone of smart base training.

Instead of trying to blast through a single 30-mile death march on the weekend (and spend the next week limping), you break it up: long run Saturday, another long-ish one Sunday.

Why They Work

• They simulate race fatigue without breaking your body in one go.
• They train your mind to push through when you’re running on fumes.
• They let you stack volume realistically for folks with 9-to-5 jobs.

Let’s say you’re prepping for a 50-miler.

Instead of a 35-mile grind that wrecks your legs and family weekend, you hit 20 miles Saturday and 15 Sunday.

You still bank 35—but smarter, safer, and with way better recovery.

---

Don’t Screw This Up

Biggest mistake? Going too hard on day one and trashing yourself for day two.

👉 The goal isn’t pace—it’s time on feet. Easy miles, steady grind.

Start small in base phase: maybe 10 + 10 or 2 hours + 2 hours. Later, when your engine’s stronger, yeah—you might go for 20 + 25. But only if your body and life can handle it.

Elite coaches suggest that for 100K or 100-mile races, you don’t need one giant long run.

A pair of runs that total slightly more than your race distance spread across two days is enough to supercharge endurance without wrecking your joints.

---

Pro Tips for Back-to-Back Mastery

• Don’t do them every weekend—these are special weapons, not your default. Use ‘em in build phases.
• Recover hard afterward. You’re putting stress on your system, and that needs to be respected.
• Midweek miles matter less—shift your big runs to weekends if that’s what your schedule allows.

And yeah, it’s a confidence boost like no other.

If you can run 20 miles on Sunday after 25 on Saturday? You’re ready for race day.

You already know how it feels to run on tired legs—and you didn’t quit.

Volume Traps & Injury: Don’t Let Ego Write Checks Your Body Can’t Cash

Here’s the thing no one tells you when you’re ramping up for ultras: enthusiasm is sneaky-dangerous.

It can push you to double your mileage in a month, chase your buddy’s 80-mile week on Strava, or tack on “just a few more” long run miles when you’re already fried.

That’s how people end up with busted IT bands, stress fractures, and months of bitter DNS regret.

Let me say it loud for the runners in the back: more isn’t always better.

And just because elites can survive 100-mile weeks doesn’t mean you should try to match them.

Most of us have full-time jobs, families, and—let’s be honest—not the genes of a mountain goat. Trying to copy pro training with an amateur lifestyle is a fast track to burnout.

Here’s another one of my golden rules: It’s way better to show up a little undertrained than broken.

Find Your Volume Ceiling—Then Respect It

Want to train smart? Figure out your personal mileage ceiling—that invisible line where your body stops bouncing back.

How do you know where it is? Watch for red flags:

• You’re always sore, even after rest days.
• You’re sleeping like crap.
• Your morning heart rate is creeping up.
• You’re dreading runs you used to enjoy.

That’s your body throwing a red flag. It’s not weakness—it’s biofeedback. For some, 60 miles a week is fine.

Others start unraveling at 40. And guess what? That’s okay.

Ultra training is individual.

The base phase isn’t a pissing contest—it’s about building a foundation that won’t collapse the moment you hit race pace.

The Other Trap: Skipping Recovery

Another classic mistake? Skipping rest like it’s optional.

Spoiler: that’s when you actually get stronger.

Every 3–4 weeks, cut back your volume 20–30%. Let your body absorb all the stress you’ve stacked up.

These “cutback weeks” are where the magic happens.

And if you’re older, injury-prone, or just tired of pounding pavement every day, cross-training is your best friend.

Hop on the bike, swim some laps, row a bit.

You’ll still boost your aerobic engine—without wrecking your joints.

Masters runners: You’re not 22 anymore. I say that with love. Back in the day, maybe you handled 70-mile weeks on pure stubbornness. Now? Smart beats stubborn.

Also—don’t ignore little pains. That tight ankle or cranky knee?

If you keep stacking miles on it, it’ll blow up. Stretch. Strengthen. Get it looked at early. Protect the machine.

Ultra Running is Full-Body Work

Here’s something that sneaks up on folks coming from the marathon world: ultras beat up your whole system.

Not just your lungs or your quads—but ligaments, tendons, stabilizers, joints.

Running 5 hours over rocky terrain isn’t just cardio—it’s a test of your body’s durability. And that stuff—Achilles, knees, hip flexors—takes way longer to adapt than your heart and lungs. Just because you feel “cardio strong” doesn’t mean your body’s ready for that extra 15 miles.

Think long term. I’m talking multi-year development. Some of the strongest ultrarunners I know built up slowly over 2–3 years. And now? They’re unbreakable.

Trust me: There’s no prize for finishing an 80-mile week and skipping the race due to injury.

Consistency beats mileage. Always.

Hill Training: Build Those Mountain Legs

If your race has climbs, your training better have climbs. Hill work isn’t optional—it’s how you build real strength, grit, and climbing power.

let me show you how:

• Hill repeats: Pick a steep climb. Power-hike up for 5–10 minutes. Jog down. Repeat till your legs whimper. This builds that uphill hiking engine you’ll need when running isn’t efficient.
• Uphill tempos: Hard, steady effort uphill. Like a 30-minute grind up a ski slope. Brutal, but it builds aerobic capacity and mental steel.
• Hiking intervals: One of my favorites. On a long hill, go 2 minutes hard hike, 1 minute run, and repeat. Teaches you how to switch gears and keep moving efficiently on rolling terrain.

But wait David, I don’t have any hills where I live.ù

No problem. Time to get creative:

• Treadmills with incline.
• Stair machines.
• Parking garages. Yes, seriously.

Downhill work has its place too. Controlled descents at a steady pace condition your legs for the pounding. But go easy—downhill speed work is where overuse injuries love to hide.

 

Tired-Leg Running: Train the Mind, Not the Ego

Not every run in your plan will feel fresh. In fact, a lot of them shouldn’t.

Fatigue runs are where the real ultra mental reps happen.

I talked about back-to-backs, but this also includes:

• Short recovery runs the day after a big session.
• Two-a-days (one run AM, one PM).
• Midweek slogs where you’re running on fumes.

These aren’t junk miles—they’re gold.

You’re teaching your legs to move through the fog.

You’re teaching your brain that pain isn’t the boss.

You’re developing the ability to dissociate from discomfort and lock into rhythm.

But this is where runners get cocky and screw it up.

Fueling for Ultras 

Ultras?

They’re not just long races — they’re moving buffets with timing chips.

That old joke about ultramarathons being glorified eating contests?

There’s real truth there. If you don’t eat right, your legs don’t matter.

Your training doesn’t matter.

You’ll be curled up at mile 70 with a sloshing gut and no gas in the tank.

I’ve seen it happen — strong runners, shredded quads, but zero calories left upstairs. Lights out.

You simply can’t out-run an empty fuel tank. Not in a race where hours stretch into double digits.

You have to feed the machine — early, often, and smart. Let’s break down how to do that without puking your guts out at mile 90.

Golden Rule: Eat Early, Eat Often

Here’s the truth bomb: if you wait until you’re starving or bonking, it’s already too late. Your brain and gut slow down together, and once you’re in the hole, digging out takes forever — if you can even recover at all.

That’s why the mantra is always: “Eat early, eat often.” Start fueling within the first 30–60 minutes, even if you feel fresh.

Especially then. Don’t trust your hunger cues — they go haywire during long efforts. And as you might already know, exercise suppresses hunger so if you wait to feel hungry, you’re already behind.

Pro move: Set a watch alarm every 30 minutes. When it beeps, you fuel. No debate. Gels, drink mix, banana bites — whatever your gut likes, get it in.

Aiming for 200–300 calories per hour is pretty standard. That’s about 40–60g of carbs, give or take.

Some elites can handle up to 90g/hr, but don’t force it. Work your way up. Most folks can start with one gel every 30–45 min. That’s about 100 cal, 25g of carbs. Add in sips of drink mix and maybe a snack, and you’re in the zone.

 

When Things Go South, Improvise Like a Pro

Look, not everything you planned will work. That’s why I tell runners to always have a Plan B… and a Plan C. Hell, have a backup for your backup.

If X food doesn’t sit right? Go with Y.

Can’t do gels? Drink calories.

Sweet stuff make you gag? Salt that potato like a truck stop fry basket.

Some runners even do a small bit of fat or protein later in the race — peanut butter, a bite of cheese — only if they know their stomach can handle it. (Test this in training — or regret it later.)

🛑 But be careful with caffeine. Coke and Mountain Dew can help, but too much can give you the jitters — or worse, a rebound crash. Use it like a weapon.

Small sips, late in the race when your brain’s going foggy.

Hydration & Electrolytes: Terrain, Sweat, and Survival

Listen up—hydration isn’t just about guzzling water.

It’s about balance.

And when the heat’s on or the trail’s long, getting it wrong can wreck your race faster than bad pacing.

I’ve seen it all—runners cramping like they’re doing the worm on the side of the trail, others nauseous and foggy-headed because they overdrank and flushed out all their sodium.

One of my training buddies kept drinking water like it was his job. By mile 40, he was slurring his words and stumbling.

Classic hyponatremia—he diluted his blood sodium so bad he couldn’t function. Scary stuff.

Now here’s what you need to know:

In hot or humid races:

• You sweat more.
• You lose more salt.
• You need more fluids and more electrolytes.

Salt tabs, electrolyte drink mixes, sports drinks—use them. A common ballpark is one electrolyte tab or salt capsule per hour if you’re sweating buckets. But don’t just follow a rule—watch your body.

In cold weather:

You might not feel thirsty.

You might not sweat much.

But don’t fall into the trap of overdrinking just because you “think you should.”

That’s where people screw up in cooler races—chugging water when they’re not sweating much, then ending up bloated and low on sodium.

Even the Western States folks warn against this: “Don’t drink at every aid station just because it’s there.” Sip when you’re thirsty. Balance it with electrolytes.

Sweat-Test Yourself

Do this during training: Weigh yourself before and after a 1-hour run in the same kind of conditions you’ll race in.

Every pound lost = ~16 oz of water.

That gives you a baseline of how much you need per hour.

Example: You drop 2 pounds on a hot run? You probably need 30–32 oz/hour on race day in similar heat.

If your sweat rate is high, aim to replace about 75% of that per hour—not all.

Why? Because food gives you some water too (like watermelon, soups, etc.), and your body produces metabolic water when burning fuel.

The goal isn’t to replace 100%. It’s to stay in the sweet spot—not dehydrated, not sloshing like a waterbed.

Electrolytes = More Than Just Salt

Sodium is the big dog—it keeps nerves firing, helps fluid absorption, and wards off nausea.

But potassium and magnesium matter too, especially for cramp prevention.

You don’t need a chemistry set—just eat smart and use balanced hydration. Sports drinks, bananas, broth, pretzels… they all help.

A study showed that ultrarunners who kept sodium balanced had less GI distress. Makes sense—blood sodium helps keep your gut moving and keeps you from getting that nasty “slosh and bloat” combo.

Check your pee:

• Light yellow = good
• Dark yellow = drink more
• Clear like tap water + peeing every 30 min? Ease off the water. Add salt.

Ultra Training Plans by Distance

Alright, let’s cut the fluff.

Training for ultras ain’t magic—it’s mileage, sweat, and time on feet. And yeah, the training plan for a 50K won’t look the same as a 100-miler. Duh. But the bones of the beast stay the same: build gradually, don’t get hurt, and make your long runs count.

The longer the race, the bigger the build. But here’s the kicker—not everyone needs to run 100+ kilometers a week. If your body can’t bounce back from that kind of volume, guess what? It’s not helping. Running isn’t just about stacking miles—it’s about stacking smart miles.

How Long Should You Train?

You’ll need time to build that engine. If you’ve already got a base, you can be race-ready for a 50K with 12-16 weeks of focused training. For a 100-miler? That’s often a 20-24 week haul, on top of years of base-building.

Mileage Goals (The “Realistic” Edition)

Let’s talk numbers—because I’ve coached folks who obsess over weekly mileage like it’s a scoreboard. Here’s a rough guide that lines up with what a lot of experienced coaches (and real-world finishers) go by:

• 50K: Minimum peak ~30 miles/week to finish. Want to feel strong? Get to 50+ miles/week.
• 50M/100K: Bare minimum 40 miles/week. Solid performance kicks in around 60+.
• 100M: You can survive on 50 miles/week if you’re smart about your training. Want to go big? Some do 70–80, even 100+ at peak. But careful—more isn’t always better. Plenty of strong 100-mile finishers hang in the 50–70 range.

One of my athletes once tried to hit 120 miles/week like the elites. He ended up hitting the orthopedic table instead. Lesson? Don’t let your ego write checks your recovery can’t cash.

Don’t Skip the Climbing

If your ultra has vertical gain (spoiler: it probably does), your training better reflect that. There’s a simple rule of thumb I love: over one week, hit at least as much vert as your race has total.

• Got a 50K with 5,000 feet of climbing? Try to build up to a week with 5,000+ ft.
• Training for something gnarly like Hardrock (33,000 ft over 100 miles)? That’s trickier unless you live in the mountains—but you can simulate it with a few “vert-heavy” weeks or a DIY training camp.

Long Run Realities

This is where people get nervous: how long should your long runs be?

• 50K: A single 20-22 miler (or 3-4 hours) is usually enough. Heck, some folks do a 26-30 mile run to mimic race day. But I tell runners—spend time on trails and practice fueling more than obsessing over distance. A 50K is just a marathon with dirt and snacks.
• 50M/100K: Back-to-back long runs shine here. Example: a Saturday 30 miler, then Sunday 15-20. Or toss in a 50K race as a tune-up 4-6 weeks out. That’ll humble you fast—but it builds serious grit.
• 100M: Now we’re talking crazy-town. Some do a single 40+ miler. Others go time-based—like an 8-hour effort, then another long one the next day. My take? A 50-60 mile long effort (usually in a race setting) can be a confidence booster—but it’ll beat you up. Do it right or don’t do it at all.

One runner I coached did a 50K/20-mile weekend block. Said it was the hardest training weekend of his life—but come race day, he was ready for that 3 a.m. suffering.

Taper Smart—Don’t Blow It

Don’t screw this part up.

A well-timed taper can boost your race performance by 3–6%, according to studies in the Journal of Strength & Conditioning Research. That’s free speed. You just have to not be a bonehead and overtrain.

• For a 50K: A 7–10 day taper usually works.
• For a 100M: Take 2–3 weeks to cut volume ~50%, keep a little intensity, and rest like it’s your job.

Remember: you don’t get stronger during the race—you get stronger during recovery. Don’t ignore the taper just because you “feel great.”

Key Workouts: It Ain’t Just About Going Long

Look, just because ultras are long and “slow” doesn’t mean you get to skip the hard stuff.

If you wanna last for hours out there—and finish strong, not crawling—then you need to train smart.

Every solid ultra plan I’ve seen (and coached through) includes a few non-negotiables: long runs to build that diesel engine, hills to make your legs bulletproof, and yep—speedwork.

I know, it sounds weird. Why run fast for a slow race? Because boosting your VO2 max and running economy means you can cruise at a faster pace while still feeling chill.

Trust me, that pays off big time when you’re grinding at mile 40.

When I was training for my first 50K, it looked a lot like marathon prep—but with more dirt and way more hills.

I’d hit a weekly tempo run (say, 5 to 8 miles at a steady but tough effort) and mix in intervals like 6×1 mile at a hard pace.

You gotta keep those legs snappy.

But for the long beasts—100K or 100-milers—you don’t need all-out speed.

You shift into what I call “grind gear”: longer tempo chunks or “cruise intervals” tucked right inside your long runs.

Like 3×20 minutes at a strong effort during a 3-hour run. You’re learning to push when you’re already tired. That’s gold.

And if you’re aiming at a 100-miler? Welcome to the world of overnight runs.

That’s right—some of us hit the trail at 10 p.m. just to simulate race conditions.

You gotta get your body (and mind) used to running when it’s dark and your brain’s begging for bed.

I’ve had athletes tape headlamps to hats, forget snacks, get lost—it’s all part of the process.

Customize for Real Life (Not Instagram)

Forget what you see pros doing online. You don’t need to run 75+ miles a week unless your body—and life—can handle it. If you’ve got a demanding job, kids, and you’re barely sleeping? That’s stress, and it counts toward your training load too.

I’ve coached runners who finished 100-milers on 40–50 miles per week, sprinkled with smart workouts, strength training, and a few monster weekends. One guy even podiumed at UTMB averaging just 42 miles a week. Outlier? Sure. But proof you don’t need to break yourself chasing someone else’s volume.

Training plans aren’t commandments. They’re suggestions. Listen to your body. If you’re toast, take a rest day. Swap in cycling or swimming if you need less impact.

There’s this line I love: “If you can’t recover from it, it doesn’t matter if it’s in the training plan.” Boom.

Gear for Ultra Trail Running (The No-Nonsense Version)

Look, you don’t need a closet full of high-tech toys to finish an ultra. But some gear? Non-negotiable. It’s not about looking like a catalog model. It’s about not getting wrecked out there.

In a 10K, you can show up in a pair of beat-up shoes and a cotton tee and survive. But in a 100K through the mountains? That same attitude might earn you a DNF, or worse. So let’s break down the gear that actually matters—shoes, packs, poles, headlamps, drop bags, and clothing.

And no, you don’t need the newest carbon-plated super shoes or $300 vests. What you need is gear you’ve tested, gear you trust. Race day is not the time for experiments. That’s how you end up limping home with shredded feet and a busted ego.

---

Shoes: Grip, Cushion, and the Right Fit

Shoes are make-or-break. I’ve seen runners soar and others drop—all because of what they had on their feet.

For gnarly, technical trails—think roots, rocks, vertical gains—you want something with serious traction and protection. We’re talking aggressive lugs, solid fit, and a rock plate or thick sole that keeps your feet from feeling like they’ve been tenderized with a hammer. I’ve used La Sportiva Bushidos and Salomon Speedcross for stuff like that—great grip, but yeah, they’re not plush.

On smoother, faster terrain, or mixed surfaces? You’ll want something lighter, a bit more flexible. Think Saucony Peregrine or Nike Terra Kiger. They ride closer to a road shoe, so you can actually open up your stride a bit. Some courses have road sections too—nothing wrong with rocking a hybrid shoe if you’re confident in the grip.

Big tip: size up. A half or full size bigger than your usual. Your feet are gonna swell like balloons after 30 miles. That snug fit you loved at mile 10? Might turn into a medieval torture device by mile 80.

Pro move? Keep a backup pair that’s a half-size up in your drop bag. Add some extra cushion if you can. I’ve seen plenty of folks change shoes at Foresthill (62 miles into Western States) because their feet were trashed from the earlier miles. I’ve done the same—it’s like getting a second wind, but for your toes.

And always, always test the shoes with the socks you’ll race in. Seams + long miles = blisters from hell. Stickier rubber if you’ve got wet rocks or mud, smoother outsoles for dry terrain. And unless you’re flying, carbon-plated trail shoes are probably overkill for rugged trails.

Moral of the story? Run long in your race shoes before race day. If they pass the test, they’re in. If not, ditch ’em.

What about you—what shoes have been your go-to? Ever had a blowout mid-race?

---

Packs, Poles & Headlamps: Your Ultra Survival Kit

This ain’t a 5K. You’re gonna need to carry stuff.

Most of us rock a hydration vest or pack for anything longer than a marathon, especially on remote trails.

The key is snug fit—zero bounce—and pockets you can actually reach on the move.

Load it up during training runs. Jacket, first aid, food, water… the works.

If it rubs your shoulders raw at mile 15, fix it now, not mid-race.

Now, trekking poles—absolute game-changer for serious climbs.

Most European ultras? Everyone’s using them. They give your legs a break and help you stay upright when the trail turns sketchy.

But don’t wing it. If you haven’t trained with poles, they’ll just piss you off.

Learn how to stash and deploy them smoothly.

I keep mine in a drop bag for late-stage climbs when my legs are toast. If you’ve got steep ascents early on, consider starting with them—but know it means you’ll be using your upper body too. It’s a trade-off.

Headlamps. Don’t screw this up.

If your race goes into the dark (or starts before sunrise), you need a solid, bright headlamp.

Not your kid’s camping light.

Many races require a minimum lumen rating (200+). I’ve got a Petzl that I trust with my life—but I always pack spare batteries. Cold weather drains them fast.

Some swear by using two lights—head and waist. That combo helps with depth perception by throwing shadows that show the dips and bumps better. Worth trying in training.

Here’s a mistake I’ll never repeat: showed up to a night race once with “fresh” batteries… that died 40 minutes in. I was blind in the middle of a forest. Had to use my phone to show me around then heavy rain started pouring.

Nightmare scenario.

Don’t be that guy. Double-check your light. Always bring a backup.

Drop Bags: Pack Like Your Race Depends on It (Because It Does)

Let’s get one thing straight—drop bags aren’t just “nice to have.”

Done right, they’re your secret weapon. Think of them as your personal pit stops.

It’s like having your own mini aid station stashed out there, full of exactly what you need when things go sideways. And trust me, in ultras? Things will go sideways.

Now, I’ve seen runners get saved by a single pair of dry socks—or crash and burn because they didn’t pack an extra gel when the aid station ran out of the good stuff. So here’s what I always tell folks I coach (and what I’ve lived myself):

Pack for when you’ll need stuff, not just where.

That bag at mile 75? That’s not just another checkpoint.

That’s likely where you’re hurting, cold, and half convinced this race is a dumb idea. That’s when you want your comfort foods, blister kit, a caffeine jolt, and maybe a note to yourself that says “You’ve trained for this. Let’s go.”

I’m talking real-deal survival mode: extra headlamp or batteries (because darkness hits harder than you think), meds like salt tabs or ginger chews (been there, barfed that), and always—ALWAYS—a pair of socks.

Even if you don’t swap ’em, just knowing they’re there is like mental armor. I’ve had runners hobble in with trench-foot toes, change socks, and leave that aid station like they just got new legs.

 

Layering for Ultras 

Ultras don’t play fair. You might start sweating in the sun, and six hours later be frozen on a mountain pass wondering how you got there.

That’s why layering isn’t just smart—it’s survival.

At the bare minimum, carry an ultralight windproof layer. Even a cheap plastic poncho weighs nothing and can save your race when things go south.

Add a real rain jacket—especially if your ultra’s in the mountains. Those “water-resistant” jackets some brands love to sell? Might as well wear tissue paper.

You want taped seams and something that’s actually been in the rain.

Test it. Don’t just read reviews—wear it on a rainy run and see if it holds up.

Same goes for your legs.

Cold rain? Pull on tights or waterproof pants.

Even a trash bag skirt with a neck hole can buy you time in a storm. No shame—just smart.

Gloves and a beanie? Always in my kit. I’ve had more races turn around just by warming my fingers and ears than any caffeine ever could. And if it’s hot? Flip the script—sun hat, UV shades, maybe arm sleeves you can soak in creek water to cool down.

Bottom line? You’re out there a long time, moving slow, burning through calories and body heat.

Temps at 3 a.m. feel 20 degrees colder because your body’s toast. Don’t be the runner shivering and sobbing under a Mylar blanket. Dress smart from the start.

Gear Wisdom: Run With What You Know

You ever see that runner at the start line decked out in brand-new gear from head to toe? Yeah, that’s the one you’ll probably pass later, blistered and pissed off because their fancy vest chafed them raw.

I don’t care if your jacket cost $300 or $30—if you haven’t tested it, it’s a liability.

At Leadville one year, a guy picked up a brand-new high-lumen headlamp at the expo, used it for the first time during the race… and it failed.

He was stumbling in the dark until someone handed him a backup. Guess what? His trusty old one was still at home.

I’ve seen it all. Carbon poles breaking. $250 shoes that never saw a trail before race day.

Runners too distracted by their new GPS toy to remember to eat. Don’t be that runner.

Test everything in training. Your vest should feel like a second skin. Your shoes should have mud on them. Your nutrition? Know exactly how it hits your gut at mile 50, not just what the packet says.

 

Race Day Systems: Don’t Let Logistics Wreck Your Race

Here’s the truth—when you’re out there grinding through an ultra, it’s not just your legs doing the work.

It’s your brain, your crew, your prep, your whole dang system.

In a 10K, you might not even blink at the aid table.

But in a 100-miler? You’ll spend real time at aid stations, fiddling with gear, managing food, switching socks, and maybe crying into a banana.

If you don’t have your race-day systems dialed, you’ll leak minutes like a busted hydration bladder.

Worse—you’ll unravel.

Lemme break it down for you so you know exactly what to do:

Aid Stations: Enter Like a Ninja, Exit Like You Stole Something

Picture this: You’ve been on your feet for 5 hours.

You roll into an aid station and it feels like Christmas—cheering volunteers, salty snacks, maybe even your crew waving like lunatics.

But this is where a lot of runners screw up.

Veterans have a phrase: “Beware the chair.” Because once your butt hits it, you might not get up. Time disappears.

The fix? Have a freaking plan.

About 5–10 minutes before you hit the station, start talking to yourself—out loud if you need to: “Refill both bottles. Grab three gels. Two salt caps. Banana chunk. Headlamp from drop bag.”

I found that proper planning keeps things smooth. So please think a checklist. Burn it into your brain. Some runners even count the number of tasks. That way, when you get there, it’s in and out.

If you’ve got a crew, treat them like your pit team. Tell them ahead of time what to hand you, what to swap, what to say. The best runner-crew duos can flip an aid stop in under a minute if nothing’s broken.

No crew? Still no excuse to linger. Walk in with purpose. Hit your targets—water, drop bag, fuel—and bounce. Don’t stand there scanning the snack buffet like you’re at a wedding. Know ahead: “I’m grabbing fruit and chips,” and that’s it.

 

Crew & Pacer Chaos: Plan It or Pay the Price

If your race allows pacers (most 100-milers do), they’re not just moral support—they’re your second brain when yours turns to oatmeal.

Same with your crew. They’re not there to hold your hand—they’re there to keep your race on track.

Set it up ahead of time: Who’s meeting you where? What gear are they handing you? What time windows are they expecting you?

I’ve seen top crews roll in with laminated cards or spreadsheets that list every aid station and exactly what their runner needs. That’s not overkill—it’s smart.

No signal? Yeah, that happens. So have a backup plan. What if you arrive before your pacer? Do you wait? Keep going? Make that call before race day.

When you roll into a station, yell what you need before you even stop. “New socks! Refill! More salt tabs!” That gives your crew time to prep instead of fumbling. I’ve used color-coded bags—boom, just hand me the red one and I’m off.

And don’t let your crew waste time either. It’s not a social visit. Tell them to keep it tight. Your crew should be like a NASCAR team—one swaps bottles, one hands you food, one checks your brain.

Drop Bags by Time, Not Just Distance

Here’s something I learned the hard way in my first 100-miler: don’t just think in miles—think in moments.

When will you hit that aid station? Morning? Night? Midday heat? That’s how you decide what to stash in your drop bag.

If a bag’s at Mile 70 but you’re hitting it at 2 a.m., pack for the cold. Jacket, gloves, beanie, even a mini Red Bull or caffeine gel can be game changers. I once tossed a can of coffee into a night bag—best call I made all race.

On the flip side, if your next drop is midafternoon and it’s blazing out there, load it with a hat, sunscreen, extra fluids, salt tabs. Run smart.

And if you’re anything like me, you slow down late. That’s normal.

So, stash extra snacks in those later bags—just in case aid stations run dry or you roll in after hours.

In 200-milers or 24+ hour events, you might even plan to sleep. 

Yep, real naps. Some races even require you to lie down if you’re hallucinating. So maybe toss a bivy sack or a space blanket into one of your late-stage bags. Pro tip: bring a tiny alarm or tell your pacer to wake you in 20 minutes.

Dirt naps (5-15 mins) can bring you back to life—I’ve seen it firsthand.

Real-Time Problem Solving: Don’t Let the Small Stuff Break You

Let’s get one thing straight—something will go wrong. Doesn’t matter how dialed in your training is.

You’ll chafe, blister, puke, or drop a water bottle in a porta-potty (don’t ask).

The key isn’t to be perfect—it’s to fix stuff fast and keep moving.

Got a hot spot forming? Stop. Tape it. Change your socks. Don’t wait till it’s a full-blown blister from hell. Chafing? Hit the Vaseline—every aid station’s got it. Ask. They won’t judge. We’ve all lubed up in weird places.

Stomach going sideways? Been there. Slow down, walk a bit, sip broth, chew a ginger candy or Tums. Crackers can help too. And yeah, sometimes you gotta hit the bushes.

Always carry TP in a Ziplock. Trust me—it’s a race saver.

Gear fails too. Headlamp dies? Stick with someone till the next station or whip out that mini backup you smartly taped to your pack. Shoe blowing out mid-race? Duct tape is your new best friend. I wrap a few feet around my trekking poles or bottle. MacGyver mode.

 

Know the Medical Risks (Especially in Self-Supported Races)

Some ultras—especially out in the mountains or deep desert—don’t mess around. You’re hours from help. That’s why they make you carry a foil blanket, whistle, and a tiny ER kit. They’re not being dramatic.

The Western States 100 literally warns that runners “may be subjected to extremes of heat and cold, risk of hypothermia, hyperthermia, dehydration, hyponatremia, disorientation…” Yeah—basically, your body can go haywire out there.

You have to know the signs.

• Heat stroke? Stop sweating, can’t think straight? You need shade. Now. Dump water on yourself. Get out of the sun.
• Hyponatremia? Headache, hands puffing up like mittens, or brain fog? Ease up on plain water. You need salt—caps, broth, something. And maybe hold off fluids a bit until you level out.
• Dehydration? Dizzy, no pee, heart’s thumping like a drum solo? Get fluids—slow and steady. Don’t chug. And yeah, an IV at the medical tent might help… but usually means you’re out of the race.
• Hypothermia? Shivering? Hands like ice blocks? Feeling… strangely chill about it all? That’s a warning sign. Put on gear. Keep moving to build heat. Get to the aid station, grab something warm.

Disoriented? Stop. Sit. Get your bearings. This is how “I got a little lost” turns into a search party.

Carry the damn whistle. Blow it three times if you’re in trouble. It could save your butt.

Bottom line: Don’t risk your life for a finisher’s medal. Push through discomfort? Sure. Push into legit danger? Don’t be a hero. Be alive to tell the story.

That said, if you prep smart, listen to your body, and know when to ask for help—chances are, you’ll be just fine.

---

Embrace the Chaos – Solve the Problems

Here’s my favorite truth about ultras: They’re not if something goes wrong. They’re what do you do when it does.

This changes everything. Now every blister, wrong turn, bonk, and stomach revolt becomes a puzzle to solve. You’re no longer “failing”—you’re figuring it out.

Instead of “I screwed up,” it becomes, “This happened… so I did this… and kept going.” You become a damn MacGyver with your gear, snacks, and stubbornness.

I once lost a bottle mid-race—just vanished. Refilled from a mountain stream and kept going. Another time, I teamed up with a random runner when I got spooked by rustling in the woods (don’t judge—we’ve all thought mountain lions were stalking us).

The most satisfying races? Not the perfect ones. It’s the ugly, gritty ones you finished anyway. You earn those finishes with grit, not luck.

So yeah—things will go sideways. That’s the whole point. Adapt. Problem solve. Stay in the game.

Because at the end of the day, you and the trail are co-creating the story. And some of the best chapters are written when things go off script.

Recovery After an Ultra

You crossed that finish line. You’re done, right?

Wrong.

Your legs might’ve stopped running, but your body is still screaming behind the scenes.

Muscles shredded. Glycogen tanked. Hormones out of whack. And your brain? Probably still somewhere out on the trail.

Recovery isn’t just something you should do after an ultra—it’s the last phase of your race.

And if you skip it or screw it up, don’t be surprised when injury or burnout knocks on your door a week later.

The “Bounce-Back” Window: 7 to 21 Days (Give or Take)

Here’s a loose rule: one day of recovery for every 10K raced. Some folks say a day per mile. Which sounds bonkers for a 50K (31 days off?), but let’s be real—most runners feel semi-human again within 10–14 days after a 50K or 50-miler.

For a 100-miler, give it closer to three weeks.

That said, recovery isn’t a fixed number.

I’ve seen elite 50K runners toe the line again seven days later (I’m not one of them).

And I’ve coached newer runners who needed a full month before they even looked at their running shoes again.

If you’re a regular runner like me and not living off beet juice and massage guns, take at least one solid week off.

No workouts. Just move gently—walk, stretch, spin the bike. That first week should be all about TLC, not “bouncing back.”

Research backs this up: studies show muscle damage markers, inflammation, and hormonal chaos can linger for over a week. Some folks feel off emotionally too—like you trained for something big, hit the goal, and now feel…meh. That’s normal. It’s called post-race blues. You’re not broken, you’re just human.

So yeah—sleep a ton, eat real food (not just cookies), and hydrate like your life depends on it. Because it kinda does.

If you’re itching for a run after a week? Start with a short, easy shuffle. No speedwork, no hill repeats, and absolutely no long runs yet. For 100-milers, most coaches will yell at you if you touch anything strenuous for at least two weeks. Listen to your body and your resting heart rate. If climbing stairs still feels like Everest, you’re not ready yet.

Try the “hop test”: if you can hop on one foot without pain or soreness, you might be ready to jog.

Oh—and don’t be shocked if you catch a cold. Your immune system takes a hit after ultras. So steer clear of sick coworkers and pack your meals with fruits and veggies. Vitamin C isn’t a gimmick after a 100-miler—it’s armor.

---

Sleep, Protein, and Hydration 

Let’s talk basics. You don’t need fancy supplements or recovery boots. You need these three pillars locked in:

Sleep: The Real Performance Enhancer

This is where your body does the real rebuilding. But after a race, you might feel jacked up on stress hormones—adrenaline, cortisol, all that stuff that kept you moving through the pain cave. It might mess with your sleep for a few nights.

Been there. Post-race insomnia is real. Strange dreams, restlessness, night sweats—I’ve seen it all.

Set up your sleep like you set up your aid station:

• Dark room
• Cool air
• No phone
• Maybe a magnesium supplement to calm your nerves

Lost sleep during an overnight race? You can’t fix that with one night in bed. Plan for extra hours all week. And yeah—don’t be a hero. Take a day off work if you can.

Protein & Real Food

Some runners crush a burger at the finish line. Others can’t keep down a single bite for hours. Either is normal. But once your stomach is back online, you’ve got work to do.

You need protein—about 1.2 to 1.7 grams per kilo of bodyweight per day while recovering. That’s like 20–30 grams of protein per meal for most of us. Mix in some anti-inflammatory foods too:

• Fish, nuts (omega-3s)
• Berries, greens, turmeric
• Basically, stuff your grandma would approve of

Don’t slash calories because “the race is over.” Your body is literally rebuilding torn muscle. It needs fuel.

That said, don’t go on a junk food rampage either.

A donut or beer to celebrate is fine.

But heavy sugar and alcohol right after can jack up inflammation and delay healing.

You might be dehydrated, your kidneys are working overtime, and you’re likely still on NSAIDs—don’t stack booze on top of that. Wait a day or two before partying.

Hydration: More Than Just Water

You lost a ton of fluid out there—maybe pounds of it. Even if you drank like a camel mid-race, you’re likely still in the hole.

Check your pee. Pale yellow = good. Dark like tea? Keep drinking.

• Use electrolyte drinks for at least a day
• Eat salty foods
• Replenish minerals: magnesium, potassium, etc.

Bananas, leafy greens, electrolyte tabs—all good options.

Had brown pee during the race? That could’ve been rhabdo (muscle breakdown spilling into your kidneys). Hydrate like it’s your job and maybe see a doc. Skip the Tylenol, skip the IPA.

Oh, and some people get a little puffy post-race—swollen feet, hands, or ankles. That’s your body juggling water retention and inflammation. It usually goes away in a few days.

The “Ultra Blues” Are Real (And You’re Not Broken)

Alright, let’s get something straight: just because you crossed that finish line doesn’t mean you’re gonna be riding high forever. In fact, don’t be surprised if, a few days after your race, you feel a little… off. Maybe even downright low.

We call this the post-ultra blues. And yeah, it’s real. I’ve felt it. Almost every ultra-runner I know has too.

You pour months—sometimes years—into one massive goal. Then boom, it’s over. Suddenly there’s a void. No more long runs to anchor your week. No next big milestone staring you down.

It’s like your brain’s been firing on all cylinders—endorphins, dopamine, adrenaline—and then someone pulls the plug.

Cortisol levels, which were sky-high during your training and race, can swing the other way. You feel tired, cranky, maybe even a little hollow.

Sound familiar? Good. That means you’re human.

I’ve had athletes hit a finish line with tears of joy, then text me three days later wondering why they feel low and unmotivated.

That crash? Totally normal. Not a personal failing. It’s biology. It’s emotion. It’s the rollercoaster we all ride after chasing something big.

So what can you do?

• Celebrate properly. Don’t skip this. Reflect on what you just pulled off. Write a race report. Or just journal about it. Even if the race sucked or didn’t go to plan, process it. You earned that right.
• Talk it out. Share your story with other runners. Post it, vent it, laugh about the sh*t show that was mile 87. Trust me, you’ll find a crowd that gets it.
• Move, but don’t train. A chill walk, some yoga, or a short nature hike can lift your mood. But don’t you dare start chasing pace or mileage just yet.
• Reconnect with life. Remember hobbies? Family? Friends? Dive into those. You’ve probably put a lot on hold—now’s the time to lean into the rest of your world.
• Don’t chase another race… yet. I know the temptation. But signing up for another ultra just to fill the post-race hole can backfire. Give your body and brain time to breathe.

Sometimes there’s more going on under the hood—your hormones might still be rebalancing.

Guys might notice dips in testosterone, women sometimes see shifts in their cycle.

This stuff takes a few weeks to even out. And if the low mood sticks around for more than a few weeks? Talk to someone. A doc, a counselor, whatever works. No shame in that game.

When To Train Again (And When To Chill The Hell Out)

Let me tell you the biggest lie in running: “I feel fine, so I’m ready.”

Nah. Just because your quads aren’t screaming doesn’t mean your body’s 100%.

Your muscles may bounce back in days. Your connective tissue—tendons, ligaments, bone—needs a hell of a lot longer. And your brain?

Might still be stuck between “What just happened?” and “Do I ever want to run again?”

So here’s how to know you’re not ready:

• You’re still sore
• Your sleep is wrecked
• Your resting heart rate is up
• You feel zero motivation to lace up (and you’re usually all about it)

On the flip side, you might be ready when:

• You wake up feeling rested
• Your body feels solid, not sluggish
• The thought of a run actually excites you a little

Even then—ease back in. Try a 20-minute jog, not a 15-miler. Test the waters, don’t cannonball into them.

There’s an old-school saying: “It takes as long to recover as you spent training.”

Might be a stretch, but the idea is sound. If you trained hard for 4 months, give yourself a solid month to ramp down. Chill. Breathe. Let your fire re-ignite naturally.

Jason Koop—legendary ultra coach—says you’re ready to train when you’re excited to train. That hits hard. If the idea of hill repeats makes you gag, it’s probably not time yet.

Also: rushing it means you’re flirting with injury. I’ve seen it too many times—runners jump back in, body’s still fragile, boom: stress fracture, tendon flare-up, total burnout.

Embrace the Off-Season (Yes, Even You Type-A Runners)

This part is hard for the overachievers: do less. Better yet, do nothing for a bit.

You’ve earned an off-season. And I mean that literally. Sleep in. Hit the trails with no GPS. Grab a beer and skip the early alarm. Do stuff for fun.

Be a human again.

Run when you want. Skip it when you don’t. Maybe bike, hike, hit the gym, or just chill. If you feel that itch creeping back—the one that says “let’s plan the next cycle”—great. That’s when you know it’s time to get serious again.

Want a checkpoint? Book a massage a week post-race. It’s like telling your body, “You made it, now let’s reset.”

Rest Is Training

Let me leave you with this: recovery is not the absence of training—it’s where your training sinks in and becomes strength.

If you skip recovery, all you’re doing is digging deeper into fatigue. It’s like stacking bricks on a foundation that hasn’t cured yet. Eventually, it cracks.

Think long-term. Think years of healthy running—not just one race. And remember: the same discipline you used to hit your workouts? Use it now to rest.

You earned this pause. Own it.

Final reminder: Would you rather take a few restful weeks now—or be forced into months off from injury later?

So, you’re officially in for your first 50K? Hell yeah — that’s a big move.

When I toed the line at the Bromo Desert Ultra for the first time, I was wondering if my legs would give out by mile 30.

Turns out, the race didn’t care — it just kept coming.

That’s the truth about ultras: they’ll test every part of you, from your lungs to your gut to your mind.

But if you pace it right and prep your head for the rough spots, you’ll get through it — and maybe even cross the finish line smiling.

Let me share with you my best pacing tips and guidelines:

Pacing 101: Don’t Burn the Matchbook Early

When it comes to ultra running, I’ve one golden rule: Start slower than you want.

When the race kicks off, adrenaline will lie to you. You’ll feel fresh, fast, maybe even unstoppable.

That’s the trap.

If you’re cruising through the first hour thinking, “Damn, this feels easy,” that’s perfect — don’t change a thing.

According to Ultra Running Magazine, going out hot might feel like you’re racing, but it’s usually how runners end up sitting on the sidelines with a busted race.

You can’t win an ultra in the first half, but you sure as hell can lose it.

Lock in your “all-day” pace.

This is about managing energy, not showing off.

A smart ultra pace is often 1 to 3 minutes per mile slower than your road marathon effort — especially on technical trails.

If you normally run 8-minute miles on the road, expect 10s or 11s in a 50K — and that’s totally fine.

According to MyMottiv, most trail 50Ks fall in the 10–14 min/mile range, depending on terrain.

You should be able to chat comfortably in the early miles. If you’re breathing like you’re finishing a 5K, back off.

PrecisionHydration said it best: “It’s gonna get hard anyway. Why rush to that pain cave?”

When I ran the Mantra Ultra in Java, the first few miles felt ridiculously slow. But I kept my ego in check and held back.

Later, when others were cooked, I still had legs. That’s the game.

Run your own race.

Let the fast starters go. Seriously.

Wave and let them fly by.

You might see them again when they’re bent over at mile 22.

Research shows the most successful ultra finishers are the ones who slow down the least — not the ones who start the fastest.

In one 100K study, the best runners only dropped pace by 15% at the end. The rest? Over 40%. That’s a huge drop.

The goal is steady, steady, steady — not blow up and survive.

Keep telling yourself: “Patience now = power later.”

Hills: Climb Smart, Descend Smarter

Hike the damn hills.

No shame here. Even elite runners hike the big climbs.

I used to think power-hiking was weak until I saw a pro do it during a race and still finish top three.

In ultras, hiking is strategic.

According to iRunFar, walking the steep stuff helps save glycogen and lowers your heart rate.

If you push hard on those climbs early on, you’ll pay for it later.

Fast hike, pump your arms, stay efficient. It’s not about pride — it’s about keeping your engine running.

Go easy on the descents.

Yeah, downhills are fun — until your quads start screaming.

In one race, I bombed a long downhill just to pass a few runners.

Felt like a champ… until mile 18 when my legs turned to jelly and those same runners cruised by while I was kneeling on the trail massaging cramps.

Never again.

Here’s what I do now:

• Small, fast steps.
• Soft knees.
• No heel striking.
• Let gravity help — but not take over. That pounding adds up.

The fact is: downhill damage is a major reason people DNF ultras.

You want to feel smooth, not slammed.

Negative Splits: The Ultra Cheat Code

Running negative splits in an ultra? Sounds wild, right? But it’s actually one of the smartest ways to race — especially your first 50K.

Here’s the idea: finish faster than you started. It’s hard in a long race, but even trying gets you to run smarter early.

Ultrarunner Nick Coury has tested this approach over and over, from 50Ks to 100-milers.

His take? Going out easy lowers the odds of anything going wrong — fewer stomach issues, fewer cramps, fewer mental meltdowns. And recovery is smoother.

After one 100-miler, he said he felt like he’d only run 50. That’s the power of restraint early on.

Now look, running a perfect negative split isn’t easy — even the pros slow down a little. But the goal isn’t perfection. It’s to avoid blowing up and crawling in.

For your first 50K, just try to keep the second half close to your first. That alone separates you from the pack.

Here’s something I do: around mile 22 or 23, I tell myself, “If I feel okay, pick up the pace just a touch.” It doesn’t need to be a sprint — just a little more rhythm, a little more drive.

Having that plan makes you feel in control. It also makes the finish line feel like a reward, not a relief.

Oops, I Went Out Too Fast – Now What?

Let’s be real — this happens.

You’re hyped at the start line, the crowd’s buzzing, and suddenly you’re cruising like you stole something.

Then, bam — around mile 15, it hits you. Legs feel like cinder blocks, breathing’s gone rogue, and you realize you’ve been burning fuel like a rookie.

I’ve been there. Many of us have.

But listen — you haven’t ruined your race. You’ve just got to course correct, fast.

Back off and get your head right.

The first step? Ease up. Like now.

Drop the pace, let yourself jog or even walk for a bit. Don’t worry about what others are doing — this is your race.

Think of it as flipping the switch into “damage control mode.” Your only job is to calm your breathing and keep moving smart.

The faster you get your heart rate down and your head straight, the better shot you’ve got at salvaging the rest.

Fuel up like your finish depends on it — because it does.

If you went out hard, odds are you skipped a gel or ignored your thirst because you “felt great.”

Classic mistake.

Now it’s time to catch up.

Grab whatever your stomach tolerates — a gel, some chews, part of that bar you stuffed in your vest.

Get fluids in too. Electrolytes, water, whatever you’ve got.

I always tell runners: don’t be the person who skips an aid station thinking the next one’s close.

That’s the exact kind of thinking that ends with you curled up in a ditch.

Ditch Plan A if you have to.

Your “perfect” finish time might be out the window — and that’s fine.

This sport rewards runners who can adapt on the fly.

Maybe now it’s about finishing steady instead of fast.

Maybe it’s about just crossing that line with no more meltdowns.

That’s still a win, especially for your first 50K. And funny enough? Easing off early sometimes sets you up to pass folks later when they’re blowing up.

Stay patient. Stay in the game.

The Final Miles: Smashing Through “The Wall”

Let’s talk about that part of the race — where your body’s screaming, your energy’s gone, and your brain starts whispering,
“Why not just quit?”

That’s the wall. And it hits different in a 50K. Sometimes around mile 20. Sometimes 30. Sometimes multiple times. And yeah, it sucks.

But here’s the truth: It’s 100% normal.

The good news? It doesn’t last.

Get tunnel vision.

When it hits, zoom in. Forget how many miles are left — that’ll crush your spirit. Just focus on the next thing: one foot, one tree, one rock at a time.

I like to do a little form check when I’m deep in the pain cave.

Straighten up. Swing my arms. Maybe even force a smile. (Seriously — research shows smiling can lower your perceived effort. It’s weird but it works.)

That’s the truth. Pain, doubt, fatigue — they’re just passing through.

Your job is to keep moving until they leave.

Silence the head trash.

Late-race miles come with a lot of mental garbage.

Your brain will serve up every excuse in the book:

• “My knees are done.”
• “This is stupid.”
• “I’m not built for this.”

All lies.

I don’t trust anything my brain tells me after mile 25. It’s like a drunk friend at a bar — entertaining but not to be taken seriously.

Hold tight to your reason.

When the pain sets in deep, anchor to your “why.”

You didn’t train for months to bail now.

Whether it’s to prove something to yourself, honor someone, or just cross that finish line for the first time — remember that.

I keep a mental reel of mine:

• Every long run.
• Every sunrise workout.
• Every sacrifice.

I remind myself I’m not wasting all that effort. And I visualize that finish line — the relief, the pride, the “damn I did it” feeling.

That’s what keeps me going.

Mental Toughness Toolbox: Stay Strong to the Finish

Let’s not sugarcoat it — running a 50K will beat you up mentally just as much as it does physically.

That’s why you need more than legs and lungs to finish strong.

You need a toolbox full of mental grit tricks.

Here’s what’s helped me — and the runners I coach — push through when the wheels start coming off:

Talk to Yourself Like You Mean It

When your legs are trash and your stomach’s flipping, your inner voice better be on your side.

Negative self-talk is a race killer. You’ve got to be your own hype crew.

That’s not just a cute line — it’s a survival rule for ultrarunners.

You can also keep it simple:

• “Strong and steady.”
• “One more mile.”
• “Don’t stop now.”

Heck, I’ve dedicated my final miles to my dad, my younger self, even a coaching client who’s grinding through something tough.

The point is — find your fuel. When it gets dark out there, you better have a flashlight in your head.

Need proof this works?

According to Healthdirect, the right self-talk can carry you through the darkest spots.

And I’ve seen it firsthand — both in my own races and in athletes I coach.

Make Peace with the Pain

Pain isn’t the enemy — it’s part of the deal.

You signed up for this.

Instead of whining “Why does this hurt so much?” flip the script. Say:

“This is what I trained for. This is the hard I came to conquer.”

Ultrarunning isn’t about feeling perfect the whole way. It’s about staying calm when things get uncomfortable.

Some of the best runners I know actually welcome the discomfort like an old friend.
They say, “Alright pain, let’s do this.”

Here’s what helps:

• Scan your body — feet ache? Quads screaming? Cool. Don’t judge it, just notice it.
• Keep moving. Don’t argue with it.
• Smile if you can — it actually helps.

According to TrailRunnerMag, accepting discomfort without labeling it as “bad” can keep you grounded and mentally stronger.

I’ve used this trick more times than I can count.

When you stop fighting the pain, it loses power.

And when you move with it — not against it — you unlock another level of toughness.

50K Ultramarathon FAQs – Real Talk Before the Big Day

Let’s tackle some common questions I hear from runners gearing up for their first 50K.
These aren’t just generic tips — this is what I’ve seen work (and fail) out in the real world, for myself and for runners I’ve coached.

Q: What should I eat before a 50K?

A: Think of it like this — you’re not “carb loading” to the point of needing to unbutton your jeans.

You’re just topping off the tank.

According to current guidelines, you want around 8–12 grams of carbs per kilo of bodyweight per day, starting 36 to 48 hours before your ultra.

If you weigh about 150 pounds (68 kg), that’s roughly 550g of carbs per day — about 2,200 calories just from carbs.

But don’t go crazy.
Stick to simple, familiar foods that your gut knows how to handle:

• White rice
• Pasta
• Bread
• Oats
• Bananas
• Potatoes

Don’t experiment with anything wild now.

This isn’t the time to try a vegan sushi burrito or down three protein shakes.

• The day before the race:  Eat normally but focus on balance. You want carbs, yes, but not so much that you feel like a bloated beach ball. Keep the fiber and fat low. Skip the giant salads and greasy dinners. Trust me, I’ve made that mistake and paid for it the next morning.
• Race morning: Eat something solid about 90 minutes to 2 hours before the start. I usually go for toast with peanut butter and banana, or oatmeal with honey and some nuts. Around 300–500 calories does the trick. Nothing too fibrous.

Here’s the full guide to fueling your 50K race.

Q: How should I pace a 50K—especially my first one?

A: One word: slow.

Slower than you think.

Slower than that.

That first hour?

It should feel almost boring. You’re holding back while your adrenaline screams “Go!” That’s the trap.

Most first-timers get sucked into the early rush and then crash hard by mile 20.

The golden rule I give my runners:

Run the first third stupid-easy, the second third smart, and if you’ve got anything left in the final third, use it.

If you’re running trails, hike the steep climbs.

Everyone does it — even elites.

Don’t destroy your legs trying to be a hero on the uphills. Let gravity help on the downhills, but don’t hammer so hard that you wreck your quads.

Use Rate of Perceived Effort or heart rate to stay in that “I could do this all day” zone. If your breathing is labored early on, you’re probably going out too hot.

Q: What if I hit the wall mid-race? How do I push through when everything hurts?

A: Hitting the wall happens. The trick is how you handle it.

First, check the basics:

• Fuel: Are you eating enough?
• Hydration: Dehydration will crush your energy.
• Salt: Cramping or dizzy? Pop some electrolytes.
• Pace: Might be time to ease up a notch.

If you’re feeling totally drained, take in some sugar — gel, fruit, sports drink — whatever’s on hand.

Walk a bit. Regroup.

I’ve had races where I felt destroyed at mile 20, but after a short walk and some snacks at an aid station, I got a second wind and cruised the final stretch.

Some mental tricks that work:

• Break the race into chunks. “Just make it to the next aid station.”
• Talk to yourself. I do it all the time — out loud. “You’ve been through worse. Just move your damn feet.”
• Music? Save your best playlist for mile 40. I’ve blasted 90s rock through my phone speaker in the middle of nowhere to stay in the game.

And remember why you signed up in the first place.

Think of the training you’ve done. The people cheering you on.

That stuff matters more than perfect pacing.

Q: How long should I taper before a 50K?

A: About two weeks is the sweet spot for most runners.

If you’ve been running big mileage or feel worn down, give yourself three weeks.

Your last really long run should be about 3 weeks out.

Here’s your taper plan:

Two weeks out: Cut mileage to 60–70% of your peak.

Race week: Drop to 30–50%, mostly short, easy runs.

So if your peak was 50 miles/week:

• Drop to around 30–35 miles two weeks out,
• Then 15–20 miles (plus the race) the final week.

Some folks like to keep a bit more volume. Others feel better resting more.

Listen to your body.

It’s normal to feel cranky or sluggish during taper. I call them “taper tantrums.”

You start doubting your fitness. You feel like a couch potato.

Don’t worry — you’re not losing gains.

You’re just recharging the system.

You can toss in a few strides or short tempo bursts to stay sharp, but don’t go beast mode.

Use the down time to:

• Prep your gear
• Plan race logistics
• Get mentally dialed in

I always feel like a caged lion the day before an ultra — and that’s how I know the taper worked.

What about you?

• What’s your go-to pre-race meal?
• Have you ever bonked hard in a long race?
• How do you mentally push through when your legs want to quit?

Drop your answers or questions in the comments — I read everything.

Let’s trade war stories and get stronger together.

So, you’ve logged the miles for your 50K ultra race, hammered out those back-to-backs, and dragged yourself through some gnarly trail runs.

Now race day’s breathing down your neck.

And here’s the truth: if your nutrition, hydration, or gear setup is off, it doesn’t matter how fit you are—you’ll suffer.

A 50K isn’t just about running. It’s about managing your energy, keeping your gut happy, and staying comfortable hour after hour.

Let’s break it down—what to eat, how to hydrate, and what gear you better not mess up.

Fueling for the Long Haul 

You’ve probably heard the joke: “Ultras are just eating contests with some running in between.”

It’s funny because I honestly believe it’s the truth.

In a half marathon, maybe you can get away with a couple of gels and some water.

But for a 50K? Nope. If you show up with just a gel or two in your shorts pocket, you’re setting yourself up for a bonk-fest.

You need a fueling plan—and you need to practice it in training.

Why You Need to Eat

Once you’re running longer than two hours, your body starts running low on stored carbs (aka glycogen). Keep pushing without refueling, and your legs are gonna quit on you.

In a 50K, you’re likely out there for 5 to 8 hours—or more—so skipping calories isn’t an option.

How Much to Eat

The general rule: shoot for 30–60 grams of carbs per hour. That’s about 120–240 calories per hour.

If your stomach can handle it, some athletes even push closer to 90g/hour (360 calories), but you’ve gotta train your gut for that.

When I first started ultra training, I could barely stomach 30g/hour—one gel and maybe a few sips of sports drink.

I worked my way up by testing different combos: gels, chews, sports drinks, bananas, mini sandwiches… some of my long runs felt more like a buffet than a workout.

Practice Eating Like It’s Race Day

Here’s the golden rule: nothing new on race day.

Use your training runs to test what sits well—and what sends you sprinting for the bushes.

For example, I couldn’t stomach anything sweet early on. Gels started tasting like syrupy glue.

Luckily, I had practiced with salty stuff: peanut butter pretzels, tiny boiled potatoes, even cheese crackers. That variety saved my stomach—and my race.

And it’s not just me. Research backs this up: studies show that as runners go longer, they often lose the desire for sweet foods and crave salt or umami instead.

Trust your tastebuds—they’ll start yelling when it’s time to switch things up.

Eat Early, Eat Often

One study on ultramarathon nutrition found that finishers were consistently hitting 250+ calories per hour, while those who DNF’d were only managing under 200.

That stat hit home. Now, I set a timer on my watch to nudge me every 30–40 minutes: “Eat something—even if you’re not hungry yet.” Because once you feel like you need food, you’re already behind.

Stay on Top of Hydration 

Food matters, but so does water. And if you mess this up, you won’t just feel tired—you could cramp, overheat, or worse. Dehydration is brutal.

How Much to Drink

The usual range is about 500–750 ml of fluids per hour (around 2–3 cups), depending on the weather and how much you sweat.

But it’s not one-size-fits-all. Your thirst cues, the humidity, and your sweat rate all play a part.

You might’ve heard “drink to thirst.”

That advice is now pretty common, and it works well—for some.

In fact, experts now agree that for many runners, letting your body guide you is enough to stay properly hydrated.

But… that doesn’t always apply during ultras.

When you’re tired or cold, thirst cues can shut off.

Coach Jason Koop has warned about this—he says you can’t just trust thirst, especially when running at altitude or in extreme conditions.

His advice? Figure out your sweat rate during training and aim to replace about 90% of what you lose.

What I Do

Personally, I drink every time I fuel. It keeps things simple: gel + a few sips.

And if it’s hot or dusty like that desert stretch I ran in Bromo? I up the intake.

I was easily downing 600–700ml/hour on that course just to keep up.

In the mountains, with cooler temps, I might drink half that.

But I always make sure I’m sipping regularly.

Don’t Skip the Electrolytes

Here’s where some runners mess up.

If you sweat buckets and only drink water, you risk flushing out your sodium levels.

That can lead to something dangerous called hyponatremia. Not fun.

So include electrolytes—whether through sports drinks, drink tabs, or salty snacks.

I personally don’t use salt pills. Instead, I mix electrolyte tabs into my bottles and eat things like pretzels or crackers. That combo has kept me balanced on the trails.

Race Day Nutrition: Fueling for the Long Haul

Look, running 50K isn’t just about strong legs — it’s about fueling smart.

You’re out there for hours, and if you don’t eat and drink right, your engine’s going to sputter.

This isn’t the time to wing it. If you’ve trained for this, you’ve already tested what works.

Now it’s go time.

Pre-Race Fueling: The Night Before & Morning Of

The night before the race is not the time for culinary experiments. Think simple, carb-heavy, and easy on your stomach.

On my first 50K I downed a bowl of pasta, a bit of grilled chicken, and kept it bland on purpose.

I wasn’t trying to win MasterChef — I just wanted fuel that wouldn’t fight me mid-race.

The science backs it up too: carbs fill your muscles with glycogen — your body’s main fuel for long-distance stuff.

According to research by Johns Hopkins Medicine, topping off your carb stores 1–3 days out helps you last longer and push harder.

Morning of?

Keep it light and 2–3 hours before the gun goes off. Here’s what’s worked for me and my runners:

• Oatmeal + banana + drizzle of honey — solid carbs, goes down easy
• Peanut butter toast — fat and carbs combo that sits well if you’re used to it
• Banana-spinach smoothie with a scoop of protein — if you’re not big on solid food early

Skip the greasy stuff and high fiber unless you enjoy port-a-potty detours.

Coach’s Tip: Practice this in training. Race day isn’t the time to “try something new and exciting.”

Hydration: Sweat Smarter, Not Just Harder

Dehydration will wreck your race faster than any hill.

Shoot for 500–750 ml of fluids per hour — more if it’s hot or you sweat like crazy. That’s 2–3 cups every hour.

But don’t just guzzle — sip as you go.

And plain water? Not enough.

You lose sodium, potassium, magnesium — all the good stuff.

I always pack electrolyte tablets or powder in my vest.

Most aid stations offer them, but I trust my own mix.

During the Bromo Desert 50K, I made sure to sip electrolytes every 30 minutes. It saved me when the sun started cooking us alive.

Tip: Set a hydration alarm on your watch. Or use your fueling breaks as your drink cue.

Fueling During the Race: Feed the Fire

Once the gun goes off, the clock starts ticking on your glycogen stores.

Don’t wait until you feel drained — it’s already too late.

I eat something every 30 to 45 minutes. That’s usually 30–60 grams of carbs per hour.

A gel here, some banana there, maybe a salty snack if I’m feeling off.

Here’s my go-to stash for a 50K:

• Energy gels — easy, quick sugar. I use these early when my stomach’s still happy
• Bananas — carbs + potassium. Nature’s endurance snack
• Pretzels — salty, crunchy, and they keep my gut happy
• Chews or bars — good for when I need something to chew on

Note: Don’t overdo it.

I’ve coached runners who hit every aid station like a buffet. Their stomachs shut down halfway in.

Find your rhythm and test your race-day menu in long runs.

I even keep a timer on my watch to buzz every 40 minutes — not because I forget to eat, but because in the middle of a race, everything becomes a blur.

Real Talk: You Can’t Fake Fueling

Running a 50K takes more than guts. It takes a plan—and your fueling is part of that plan.

You can train hard for months, but if you mess up your nutrition, your legs won’t save you.

So, practice it. Refine it. Stick to what works.

Lemme start this with a hot take: If you’re gunning for a 50K, mileage alone isn’t enough.

Yes, mileage can only take you so far.

Now it’s time to get serious about the course itself0

Why?

Because whether it’s packed with steep mountain climbs or just long, soul-sucking stretches of flat trail, the way you train your long runs and handle terrain can make or break your race.

Worry no more.

In this article, I’m gonna share with you everything I wish someone had told me before I signed up for my first ultra.

Sounds like a good idea?

Let’s get to it.

The Long Run: Where the Real Work Happens

If there’s one thing that makes or breaks a 50K, it’s the long run.

I used to think speed workouts or back-to-backs were the secret.

They help—but nothing replaces the long run.

This is where you harden your mind and body for what 31 miles really feels like.

When I trained for my first ultra, anything over 20 miles sounded like madness.

But guess what? That’s the stuff that made me tougher—not just physically, but mentally.

You don’t wing an ultra. You train for it, one long effort at a time.

How I Structured My Long Runs

Here’s exactly how I did it—and how I coach my runners to do it too:

Start Small. Add Slowly.

Don’t try to be a hero on week one. I began with 10–12 milers and added a mile or two per week, tops.

No ego. Just steady growth.

Your body needs time to adjust, and blowing up too soon means injury—or worse, quitting halfway through training.

Fuel Early, Fuel Smart.

Let me say this loud: If you don’t eat during your long runs, you’re not preparing for race day—you’re just suffering.

I trained myself to take in something every 30–45 minutes. Gels, pretzels, bananas—test it all.

Figure out what your stomach can handle before you toe the line. And don’t skimp on fluids or electrolytes either.

One missed sip and you could be crawling through the final miles.

Play the Mental Game.

When I hit mile 16 or 18, my brain would start playing tricks—telling me I was done.

That’s when I’d chunk the miles.

“Just 5 more miles to the next gel. Then walk a bit.”

Keep breaking it down. The full 50K might seem like a beast, but if you take it piece by piece, it becomes doable.

Think Time on Feet, Not Just Distance.

It’s not just about how many miles you run. It’s about being on your feet for 4, 5, 6 hours.

Walk if you have to.

In fact, walking up hills during training taught me how to conserve energy. And guess what?

I still passed people in the final stretch who burned out trying to run everything.

Test Everything You’ll Wear or Eat on Race Day.

Your long runs are like dress rehearsals.

If your socks rub or your hydration vest bounces weird, you want to know that before race day.

I once realized my old trail shoes made my toes go numb at mile 18. Swapped them out the next week—game changer.

Elevation & Hills: Embrace the Suck

Let’s talk hills.

If your 50K has climbs, don’t pretend you’ll just wing it.

You need to train for those climbs. Period.

When I ran the CTC 50K, I hit a wall around mile 20. The course had relentless climbs that made my quads scream.

But I was ready—because I trained on elevation weeks in advance.

Here’s how I prepare for hills:

Hill Repeats (Hate Them, But They Work)

Find a hill. Charge up. Walk or jog down. Repeat until your legs say “enough.”

These sessions build serious strength—and toughness.

Think of it as gym day with a view.

Power Hiking is Not Cheating

I used to be stubborn and run every climb. Bad move.

At my first ultra, I burned out my legs by mile 15 trying to “run everything.”

Once I embraced power hiking, it saved my race.

Don’t wait until race day to practice it—train your hiking legs now.

Add Elevation to Long Runs

Don’t just do hill workouts midweek—get vertical in your long runs too.

I purposely picked trails with brutal climbs, even if it meant driving an hour to get there.

Come race day, I was ready for anything the course threw at me.

Technical Terrain: Mud, Rocks, and Surprises

Not every 50K is packed with hills, but almost all of them throw curveballs: mud, rocks, roots, and maybe a river crossing or two.

At Bromo, my first ultra, I hit everything from volcanic rock to deep sand. I learned quick: you can’t zone out.

Trail running demands attention, rhythm, and light feet.

Here’s what helped me:

Train Your Feet Like a Ninja

Don’t just stomp through trails.

Watch your footing, stay loose, and always keep your eyes a few steps ahead.

The more alert you are, the fewer faceplants you’ll have.

Strength Work Is Mandatory

You want ankle rolls and slips? Skip strength training.

But if you want to stay upright and steady, do your squats, lunges, core drills, and balance work.

Trust me—it pays off when your foot lands sideways on a root mid-race.

Run the Tough Stuff Before Race Day

Seek out trails with mess—roots, sand, rocks, all of it.

I did loops on technical terrain just to build confidence.

The more you train in it, the less it’ll rattle you when the real thing hits.

Long Runs on Technical Terrain 

You can run all the miles you want, but if your 50K has gnarly trails, loose rock, or ankle-twisting terrain, you’d better be ready for it.

The best way to prep? Get out there and suffer a little on technical long runs.

Nothing else builds the same kind of race-day grit.

Here are some of the tough lessons I picked up along the way:

1. Pace Doesn’t Matter—Effort Does

The first time I took my long run to a rooty, muddy trail, my pace tanked. It was humbling.

But here’s the truth: pace means nothing when the trail is fighting back.

What matters is staying steady and moving with purpose.

So forget your watch. Focus on effort, rhythm, and staying upright.

2. Expect Chaos—and Roll With It

Trails will mess with your plans.

One second it’s smooth singletrack, the next you’re hopping over branches or sliding down a hill that looks like a Slip ‘N Slide.

That’s part of the game.

Stay loose, stay alert, and don’t let surprises shake you.

In ultras, the ones who adapt are the ones who finish strong.

3. Train Your Brain, Not Just Your Legs

Technical runs mess with your momentum.

One minute you’re cruising, then—bam!—a rock field kills your flow.

That’s when mental training kicks in.

In the Bromo Desert Ultra, the volcanic ash felt like running on a soft beach for hours.

Brutal.

But instead of fighting it, I learned to keep moving, soak in the challenge, and shift my mindset from: “This sucks” to “This is what I signed up for.”

That mental shift saved me.

Final Thoughts: Build for the Fight, Not Just the Finish

Training for a 50K isn’t just about going longer—it’s about getting tougher.

Yes, the long runs matter.

But learning how to move through rough terrain, handle surprise climbs, and push through fatigue when the trail throws everything at you? That’s next-level prep.

You can’t wing a technical 50K.

You’ve got to put in the hours, both mentally and physically.

You’ve got to respect the terrain and train like you’re racing—not just jogging through the motions.

And hey, those gritty miles on sketchy trails?

They make crossing that finish line feel even sweeter.

So you’ve signed up for a 50K? Damn right you did.

Welcome to the wild world of ultramarathons.

Now before you let panic take over, breathe. You’re not alone.

When I signed up for my first ultra, I was staring at the confirmation email thinking, “What did I just do?”

But here’s the truth: a 50K isn’t just about being fit—it’s about being stubborn.

It’s about pushing past the voice in your head screaming, “Quit!” and answering back, “Hell no.”

Let’s break it down so you know exactly what you’re getting into—and how to show up with the right mindset.

What Exactly Is a 50K?

A 50K race clocks in at 31.07 miles.

Yep, it’s roughly five miles longer than a marathon. On paper, it might look like “just a bit more.”

But don’t let that number fool you.

Here’s the thing—most 50Ks aren’t flat road races.

These are usually trail ultras, and that changes the entire game. We’re talking technical terrain, mud, rocks, elevation gain that’ll make your quads cry, and weather that doesn’t care about your race plan.

When I ran the Bromo 50K in Indonesia, I figured, “Okay, I’ve done marathons. I’ve got this.”

Nope.

The volcanic sand, steep climbs, and blazing heat humbled me fast. I wasn’t just running—I was surviving.

So yeah, that “extra” five miles? On trail? Feels like ten. Maybe more.

Trail Ultras Are a Whole Different Animal

A 50K is less about splits and finish times—and more about the experience.

It’s about getting dirty, lost in the wild, and battling demons in your head.

It’s about that stretch where you’re climbing a mountain with a dry mouth, thinking, “I paid money for this?”

And yet, you keep going. Because there’s magic in these races.

You’ll see jaw-dropping views you never would’ve discovered otherwise.

You’ll meet trail weirdos (like me) who will cheer you on like lifelong friends.

And you’ll finish with a kind of pride that no road race has ever given me.

Mental Game: This is Where Ultras Are Won

Let me level with you: your legs will hurt. Your stomach might turn on you. But what really breaks runners in a 50K is the voice in their head.

During my first trail ultra, I started questioning everything halfway. “Why am I doing this? Am I even cut out for this stuff?”

But instead of fighting those thoughts, I started accepting them.

Here’s the lesson: In ultras, tough isn’t a surprise. Tough is the point.

Once I made peace with the pain, I stopped panicking and started grinding. When it gets hard—and it will—that’s not the time to doubt yourself.

That’s the moment to dig in.

Set Your “Why” Before You Set Foot on the Trail

If you want to survive a 50K, get crystal clear on your why.

Why are you running this thing? What’s pulling you toward it?

For me, it was simple: I wanted to see how far I could go.

I’d done plenty of marathons, but I needed to push the ceiling.

I wanted to test the machine. When things got brutal—like scrambling through sand in the heat—I reminded myself of that.

It was about proving something to myself.

What’s your why? Write it down. Say it out loud. You’ll need it when the wheels start falling off mid-race.

When It Gets Ugly, Talk to Yourself Like a Coach

One of the best tricks I’ve learned for race day? Positive self-talk. And no, I don’t mean cheesy affirmations in front of a mirror.

I mean mantras that actually hit.

In my last 50K, I started whispering, “Just make it to the next aid station.” Over and over. And when my quads were locking up, I told myself, “You’ve done harder things. This is just today’s fight.”

Corny? Maybe. But it worked. Your brain believes what you tell it.

So instead of thinking, “I’m dying,” start saying, “I’m moving.” Instead of, “I can’t,” say, “Let’s see what happens.” Tiny shifts. Big payoff.

Mental Tricks That Saved My Race

These aren’t hacks—they’re survival tools I’ve used in every ultra.

1. Break the Race into Bite-Sized Chunks

Don’t think of it as 31 miles. That’ll break you before you even hit mile 10.

I split my first 50K into 5-mile sections. Just get to the next checkpoint. Then reset. One aid station at a time. Mentally, it felt doable.

If I thought “only 5 more miles,” I could keep going. Repeat that mindset and you’ll be shocked at how far you go.

2. Progress Over Perfection

You’re not here to win Strava. You’re here to finish, to grow, and maybe surprise yourself.

In my first ultra, I got passed by runners 10–15 years older than me. At first, it stung.

But then I realized: I’m out here grinding just like them.

That’s the win.

Focus on your race. Your story. The finish line doesn’t care about pace.

3. Get Comfortable with Discomfort

Ultras hurt. If you’re hoping for a “feel-good” day, you’re in the wrong sport.

During my CTC 50K in Java, I hit mile 20, and everything hurt—knees, feet, ego. But here’s what I told myself:

“The pain is proof that I’m doing something hard. This is the price of growth.”

The pain doesn’t mean stop. It means keep showing up.

Day Before & Race Morning: Lock in the Mental Edge

Visualize Your Victory

A few days before the race, I always take 10–15 minutes to see the race in my head.

I picture the terrain. The start line. The part where I want to quit. And the finish.

That way, when race day comes, I’ve already “been there.” It calms the nerves and builds belief. I’ve seen myself win before I even lace up.

Try it. Just close your eyes and walk through the day in your head.

Training for Your First 50K: Building Your Mileage Base

I’ve coached plenty of runners through their first ultra, and here’s the thing most folks overlook: consistency beats hero workouts every time.

Yeah, speed is fun. But a 50K doesn’t care how fast you can sprint—it wants to know if your legs can keep going after three or four hours on the move.

When I was prepping for my first 50K, I already had some marathon training under my belt.

I wasn’t starting from scratch, but I still had to crank up the weekly volume.

And honestly? It took time. My knees groaned a bit, my calves complained, and I doubted myself on more than one long run.

But showing up week after week? That’s what changed everything.

Let’s talk mileage.

How Much Mileage Should You Build?

Here’s the golden rule: Don’t rush it. Runners who jump from 20-mile weeks to 50-mile weeks overnight usually end up injured—or burned out.

Instead, build it brick by brick. Here’s the mileage roadmap I recommend:

Phase 1: Base Building (12+ weeks out)

• Start small and build up: If you’re used to 20–30 miles per week, aim to bump it up gradually to 40.
• Run 4–5 times a week: Forget about pace. These miles are about getting your body used to being out there longer.
• Make the long run count: Each week, stretch it out. Start around 10–12 miles and slowly add from there.

Phase 2: Peak Training (6–12 weeks out)

• Push toward 50–60 miles per week, depending on where you’re at physically. No need to chase someone else’s numbers—listen to your body.
• The long run is your anchor: You’ll want to build up to a peak long run between 20–26 miles. That distance will test you, but it’s also what’ll give you the mental and physical confidence to toe the line on race day.

Phase 3: The Taper (Final 2–3 weeks)

• Ease off smartly: I usually cut my mileage by 20–30% each week leading into race day. Trust me, you’ll want that rest.
• You’re not losing fitness—you’re letting your body absorb the work.

Real talk: My first 50K training cycle looked like this—4 runs a week, one of them long, and a whole lot of “just get it done” attitude.

By the final month, I was logging 50-mile weeks and could handle a 26-mile training run without totally falling apart.

That kind of buildup doesn’t just prepare your body—it reprograms your brain.

Long Runs: The Bread and Butter of Ultra Prep

You want to know what separates ultra training from regular training? It’s the long run.

This is where you teach your legs to keep grinding even when they’re begging you to stop.

This is where the magic (and misery) happens.

How to Handle Your Long Runs

Think of your long runs like dress rehearsals for the big day.

Don’t treat them like Sunday strolls. Use them to learn, suffer a bit, and test everything from shoes to snacks.

1. Add Distance Gradually

Increase by 1–2 miles per week. When I first got into ultra mode, I started with a 12-mile long run and built up to 26 at a slow pace with plenty of walking breaks.

The goal isn’t to run the full 50K before race day—it’s to build enough strength and endurance so that when race day comes, your body doesn’t revolt at mile 30.

2. It’s All About Time on Feet

Forget pace. Seriously. If you’re checking your watch every two minutes, you’re missing the point. Long runs are about getting comfortable being uncomfortable.

You should be able to hold a conversation during these runs. If you’re wheezing after a few miles, back off.

3. Practice Your Race-Day Fueling

Try your nutrition plan now—not on race day. That means testing gels, bars, drinks, or whatever weird combo works for your stomach.

I found out, after a few trials, that some energy chews don’t sit well after 2 hours in the heat.

Find what works before it really matters. Pro tip: fuel every 30–45 minutes. Even if you don’t feel hungry, keep the tank topped off.

4. Prioritize Recovery

You’re not invincible. After your long runs, treat recovery like part of the plan. Stretch, eat real food, hydrate, and—yes—take a rest day if needed.

I usually schedule something super chill the next day. Easy ride, walk, or full-on couch time with ice packs.

Back-to-Back Long Runs: Build Toughness, Not Just Miles

This is where things get spicy.

Adding back-to-back long runs—like 18 miles on Saturday followed by 12 on Sunday—will teach you to run on tired legs.

That’s gold when you’re deep into your ultra and your quads are screaming.

I didn’t start with back-to-backs right away. I added them mid-cycle, once I had enough mileage in the tank.

The first few were brutal. But over time, I got better at managing fatigue. And that mental edge? It carried me through the last 10K of the actual race.

Here’s an example of a peak weekend:

Saturday: 18 miles (long, slow, steady)

Sunday: 12 miles (recovery pace, just keep moving)

It’s not about speed—it’s about stamina and learning to grind.

Don’t Sleep on Rest (Literally)

If you’re training for a 50K and skipping rest, you’re shooting yourself in the foot. No joke—rest is as crucial as your long runs. I know some runners wear exhaustion like a badge of honor, but here’s the truth: your body gets stronger during recovery, not during the grind.

Here’s how I plan my recovery:

Sleep Like It’s Your Job

You want results? Start with 8–9 hours of quality sleep, especially during big mileage weeks.

That’s when your body repairs all the damage from pounding the trail.

I notice a massive difference in my energy and mood when I shortchange sleep—don’t make that mistake.

Take a Real Rest Day

I plan for at least one full day off every week. No running. No guilt. Just letting the body breathe.

Funny thing is, I usually come back feeling more fired up after that break. It’s like hitting reset.

Stretch & Foam Roll (Even When You Don’t Feel Like It)

Post-run, I hit the mat. A few minutes of stretching and foam rolling saves me from tight quads and those annoying calf knots that creep up when you’re ramping mileage.

I’ve skipped this before and paid the price. Now it’s a non-negotiable, especially after long runs.

Refuel Right

Recovery isn’t just what you do—it’s what you eat. After my long runs, I slam a smoothie or a banana-peanut-butter sandwich.
Why? Because protein rebuilds the muscle you just broke down, and carbs refill your gas tank. It’s that simple.

Example Training Schedules for Your First 50K

You don’t have to guess your way through this.

Here’s what a smart week looks like—one at the beginning of training, and one once you’ve built a solid base.

Week 1: Just Getting Started

• Monday – Rest (full recovery day; maybe plan your week or do light mobility)
• Tuesday – 5 miles easy (chat pace—you should be able to talk the whole time)
• Wednesday – 4 miles easy (same deal, but stay super relaxed)
• Thursday – 5 miles moderate (push just a little, but don’t chase speed)
• Friday – Rest (get ready for your long run)
• Saturday – 10-mile long run (keep it easy, and try your fueling plan)
• Sunday – Rest or cross-train (bike, swim, walk, yoga—whatever feels good)

Total: 24 miles

Week 8: Mileage Creeps Up, But You’re Ready

By now, your body should be handling volume better, and your confidence is up.

• Monday – Rest (stretch, hydrate, sleep well)
• Tuesday – 6 miles easy (form-focused, chill effort)
• Wednesday – 6 miles moderate (just outside your comfort zone)
• Thursday – 8 miles moderate (hold your effort steady)
• Friday – Rest (prep for the monster weekend)
• Saturday – 18-mile long run (simulate race day—gear, pace, fueling)
• Sunday – 10-mile recovery run (slow jog, but don’t skip it—it trains fatigue resistance)

Total: 48 miles

How to Tweak the Plan for YOU

• Run Smart, Not Hard: This isn’t a speed race. Run at a pace you can sustain. Walk if you need to.
• Check in With Your Body: A little fatigue is normal. Sharp pain or exhaustion? That’s a red flag.
• Train Where You’ll Race: Hills, trails, heat—if that’s in your 50K, your training should match it.
• Consistency Wins: Don’t chase miles. Just show up week after week. That’s how you get strong.

Final Words: It’s Not About Being Perfect

Training for your first 50K is about momentum, not perfection.

I’ve had weeks where I nailed every run—and others where I was happy just to finish a few.

But every step counted.

When I finally crossed that finish line, it wasn’t because I had flawless training. It was because I kept showing up.

So forget perfection. Go build grit. That’s what carries you to the finish.
