I Was a Run-Only Purist—Until My Knees Told Me Otherwise

I used to think bikes were for people who couldn’t handle the grind. If it didn’t involve lacing up and hitting pavement, I didn’t want to hear about it.

Then my knees had other plans.

After one too many injury layoffs, I finally gave in and jumped on a bike. It wasn’t love at first spin—but I’ll tell you what: cycling saved my running. My legs got stronger, my lungs got bigger, and I stopped breaking down every time I hit peak mileage.

Let’s be clear—cycling isn’t cheating. It’s cross-training that actually builds you up. You can ride hard and still call yourself a runner. If your goal is to run stronger and longer without breaking, here’s how cycling fits in.

Why Runners Should Embrace the Bike

Cycling is the best cross-training tool we’ve got. It gives you all the aerobic work with none of the pounding—and science backs that up.

The proof: In one study, runners who swapped out 50% of their mileage for cycling held their 3K race times and VO₂ max just as well as runners who didn’t. That means you can run less, bike more, and still perform just as well.

Here’s why cycling should be part of your running plan:

Faster Recovery

Post-run soreness? DOMS after hills? Instead of hobbling around, spin it out.

• Easy bike rides boost blood flow
• They flush out junk (like lactic acid)
• They reduce soreness without adding more impact

Elite runners use cycling as “rest day” cardio. And for good reason—it works.

Build Endurance Without Breaking Down

You might hesitate to run 5 days a week for an hour (your knees would scream), but you can cycle for 5+ hours a week and feel fine.

• More aerobic volume = bigger engine
• No pounding = fewer injuries

A seasoned triathlete said it best:

“You can ride for five hours a week and not break. Try running five hours and see what happens.”

Stronger Legs = Better Running

Cycling hammers your quads and glutes—two muscle groups that runners often under-train.

After a few weeks on the bike, I noticed my stride felt stronger, my turnover improved, and hills weren’t so brutal. My cadence got quicker—because my legs learned how to fire faster, without the cost of another run day.

Injury Prevention and Rehab Gold

Got shin splints? Knee pain? Plantar fasciitis? Cycling lets you train hard without the load.

A runner recovering from plantar fasciitis said he cycled 5–6 days a week for a month. When he returned to running, he actually felt stronger—his glutes, core, and upper legs had leveled up.

Cycling keeps your cardio base alive while giving your tendons, bones, and joints a break. That’s huge for staying consistent and healthy.

It’s a Mental Reset

Burned out from pounding the same loops every day? The bike brings variety.

• Ride through a new route
• Try a spin class with music blasting
• Or hit the trainer while watching Netflix

You’ll stay mentally fresher. And that makes a huge difference in long-term training.

One marathoner spent a year doing mostly cycling with some maintenance running. When she returned to racing, she was running 2 minutes per mile faster. That’s not luck—that’s smart training.

Muscle Breakdown: What Works When

Understanding the difference between running and cycling muscles helps you train smarter—and keeps you from being blindsided when switching between them.

Why it matters:

Cycling is low-impact, seated, and quad-heavy. Running is weight-bearing, impact-loaded, and calf-dominant.

That’s why a cyclist hopping into running might be shocked when their calves cramp and feet ache—those muscles never had to deal with impact before. And why runners feel their quads burning out after a few hard hill climbs on the bike.

But When You Combine the Two…

You get the best of both worlds:

• Stronger quads and glutes from the bike
• Durable calves and foot strength from running
• More total aerobic volume with less injury risk
• A fresher brain and a body that recovers smarter

It’s the one-two punch that builds tough, injury-proof legs and keeps you consistent—year after year.

Cycling Safety: What Runners Get Wrong (And How to Get It Right)

When I first started cycling, I figured, “I’ve ridden a bike since I was 10—how hard could it be?” Big mistake.

Within weeks, I had a few close calls that shook me up and made me realize: cycling on the road is a whole different beast than running.

You’re moving faster, sharing space with 2-ton vehicles, and your machine has gears, brakes, and moving parts to manage. Here’s what I learned (sometimes the hard way), and what every runner-turned-cyclist needs to know to ride safe.

1. Follow the Rules Like You’re Driving

On a bike, you’re not a pedestrian—you’re a vehicle. That means:

• Ride with traffic, not against it
• Stop at red lights and stop signs
• Yield when appropriate

Why? Because predictable riders are safer riders. When you follow traffic laws, cars know what to expect from you. That’s how you earn space and respect on the road.

2. Get Off the Sidewalk

Tempting? Yes. Safer? Nope.

Sidewalk riding is riskier than it looks:

• Drivers won’t see you coming at intersections
• You’ll scare pedestrians
• And you’ll likely end up in a car’s blind spot

If you’re nervous around traffic, pick quiet side streets or bike paths. But stay off the sidewalk. Trust me—you’ll be safer on the road where drivers expect you to be.

3. Be Visible. Be Predictable.

Visibility is survival.

• Wear bright gear
• Use a white front light and red rear light at dawn, dusk, or in shade
• Don’t weave between parked cars
• Take the lane when needed, especially if it’s too narrow to share safely
• Use hand signals like you mean them—left, right, slowing down

Think of yourself as a communicator on wheels. When drivers know what you’re doing, they’re less likely to hit you.

4. Learn Your Gears (Before You Need Them)

Coming from running, I didn’t think about gears until I hit my first hill… in the wrong gear. I practically stalled out and almost tipped over. Lesson learned: shift early.

Here’s the rule:

• Downshift before a hill or stop
• Keep a smooth cadence, not a grind
• Don’t wait until your legs are screaming to change gears

Smooth shifting = happy legs.

5. Keep Your Head Up, Always

As runners, we get away with zoning out. On a bike? You do that, you’re toast.

• Scan the road ahead for potholes, glass, car doors, people
• Stay out of the door zone—at least 3 feet from parked cars
• Watch every intersection and driveway
• Make eye contact with drivers when possible
• No texting. And if you listen to music, one earbud max

Riding defensively isn’t being paranoid—it’s being smart.

6. Ride With a Group or a Buddy

If traffic makes you nervous, find a group ride or ride with a friend. You’ll learn:

• How to draft
• Group hand signals
• How to ride in traffic without panicking

And yeah—you’ll be more visible in a pack. I joined a few local rides early on, and I credit those miles for giving me the confidence to ride solo later without fear.

7. Pre-Ride Safety Check

Every time, before you roll:

• Check tire pressure
• Test your brakes
• Lube your chain
• Helmet on, ID in your pocket, cash and phone just in case

Optional but smart: mini first-aid kit (road rash happens).

Doesn’t take long, but it could make all the difference when things go sideways.

Sample Week: Running-Focused With Cycling for Support

So you’re trying to run strong and keep the wheels spinning? Smart move. But here’s the deal—you can’t go hard every day. Running and cycling both beat you up in different ways, and if you treat every day like a workout, your body’s going to push back… hard.

I learned this the hard way after stacking a tough track session on a Tuesday with a 20-mile “easy” ride on Wednesday. Spoiler alert: by Thursday, my hamstrings were plotting revenge. Lesson learned: if you want to train consistently, you’ve got to train smart.

Weekly Focus: Prioritize Running, Use the Bike to Boost Recovery and Build Endurance

This plan works great if you’re prepping for a race or care more about maintaining running performance while letting the bike help you recover smarter and stay injury-free.

Sample Week Breakdown

Monday: Easy Run (30–40 min)

• RPE: 3–4 (comfortable conversation pace)
• Purpose: Shake out the weekend fatigue
• Optional: light core or bodyweight strength work

Coach tip: Keep this truly easy. Save your legs for Tuesday.

Tuesday: Hard Run Workout

• Examples: 6 × 400m at 5K pace, 3 miles at tempo, or fartlek-style intervals
• Purpose: This is your key speed session. Bring the focus.
• NO cycling today unless it’s a lazy spin (10–15 min max)

Coach tip: Quality > quantity. Nail the form, hit the paces, and recover hard afterward.

Wednesday: Recovery Ride (20–30 min spin)

• Effort: Zone 1 (RPE 1–2, embarrassingly easy)
• Cadence: 90+ RPM with zero resistance
• Purpose: Circulation, not training stress

Coach tip: If your ego’s getting in the way of spinning easy, ride indoors where no one can see you. Or skip it. This ride should feel pointless—that’s how you know it’s doing its job.

Thursday: Steady Medium Run (45–60 min)

• Effort: Zone 2 (RPE 5–6)
• Optional finish: A few 20-second hill strides to wake up the legs
• Purpose: Aerobic development and controlled endurance

Coach tip: You should finish this with gas left in the tank. If you feel wiped, you went too hard.

Friday: Moderate Cycling Workout (40–60 min)

• Example: 5 × 3-minute hill climbs with 2 min recovery spins
• Effort: RPE 7–8 on the climbs, Z1/Z2 the rest
• Purpose: Strength without impact

Coach tip: Stay seated, drive through the glutes. Think of this as gym day for your legs—with less risk to your knees.

Saturday: Long Run (75–90+ min)

• Effort: Easy Zone 2 (conversational pace)
• Purpose: Time on feet, build endurance

Coach tip: If you’re looking at your pace, you’re doing it wrong. This is about building the aerobic engine, not proving how fast you can run tired.

Sunday: Rest or Gentle Active Recovery

• Options: Full rest, light yoga, easy swim, or a 15–20 min recovery ride
• Effort: Minimal. Nothing that requires willpower.

Coach tip: Adaptation happens when you let your body breathe. If you always feel “on,” you’re not recovering—you’re just breaking down slowly.

Weekly Mix Recap

• Running: 3–4 days (2 hard, 1 long, 1 easy)
• Cycling: 2–3 sessions (mostly light, with 1 quality day)
• Intensity: Balanced across the week (never back-to-back hard days)

Sample Week 2: 50/50 Balanced Plan

(aka The “Stay Healthy, Still Get Fit” Setup)

If you’re injury-prone, coming back from a strain, or just want to give your joints a break, this kind of week is gold. Half running, half cycling, smartly split. You’re still logging quality, but without beating your legs into the ground.

This plan keeps your aerobic engine revving while reducing impact—and gives your body room to recover and adapt. Let’s break it down.

Weekly Overview

• Goal: Maintain running fitness, reduce injury risk, and build cycling strength
• Structure: 3 run days (1 hard, 1 steady, 1 short/off-bike) + 3–4 bike days
• Intensity: One hard run, one moderately intense ride—rest is aerobic or recovery

Weekly Schedule

Monday – Easy Recovery Ride

• 45 minutes
• Spin easy, Zone 1
• High cadence, low resistance

This isn’t training—it’s flushing out fatigue. Spin the legs, loosen up, maybe toss on a podcast or just zone out. It’s active recovery after a bigger weekend. Keep it super chill.

Tuesday – Quality Run Workout (Speed Play or Intervals)

• ~5 miles total
• Main set: 6 × 2-minute pickups (RPE 8+)

Time to push. With Monday’s ride behind you, the legs should feel primed. Go by effort, not pace. Keep the pickups strong but sustainable—you’re not trying to win a 400m here. Easy jogs between reps. Don’t skip the warm-up and cooldown.

Wednesday – Endurance Ride (Zone 2 Builder)

• 60–90 minutes
• Steady Zone 2 ride, conversational effort

This replaces your typical midweek medium-long run. It builds aerobic capacity without the pounding. Indoors? Load up a podcast or audiobook. Outdoors? Pick a flat or rolling route. You’ll finish feeling worked, not wrecked.

Thursday – Steady Run (Cruise & Optional Strides)

• 40 minutes, easy pace (Zone 2)
• Optional: 4 × 20-second strides post-run

Nothing fancy here. Just log miles, enjoy the movement. This could be a trail day or a soft surface run. Strides at the end keep your form sharp, but skip them if anything feels tight.

Friday – Strength or Light Cross-Training

• Option A: 30 min easy spin, swim, or elliptical
• Option B: Strength or PT work (glutes, core, mobility)

This is prehab day. Do your foam rolling. Hit the hips and core. If you’re rehabbing, this is where your PT homework goes. Don’t go hard—this day is about maintenance, not maxing out.

Saturday – Long Ride + Brick Run (Optional)

• 90-minute bike ride (Zone 2 with optional surges)
• Optional 10–15 minute transition run (slow jog)

Here’s your “combo day.” Start with a solid aerobic ride. In the second half, add some short 1-minute surges every 10 minutes if you feel strong. Then, toss on the running shoes for a short brick jog—just to get that jelly-leg adaptation in. Keep it slow and smooth. If you’re injury-sensitive, skip the run. No shame.

Sunday – Rest & Recovery

• Total rest
• Eat well, walk, stretch

Recharge. Hydrate. Maybe do some light mobility or a chill walk. No structured training today—give your nervous system a full breather.

Training Balance Tips

• Listen to your body.
• If a ride leaves your legs cooked, ease up on your next run.
• If your long run takes more out of you than expected, spin instead of smashing intervals the next day.
• Flexibility > perfection.

Red Flags to Watch

• Morning heart rate +5 bpm above normal?
• Trouble sleeping, constant fatigue, or low motivation?
• Legs feel like lead bricks for more than two days?

Those are signs you’re doing too much. Back off. You won’t lose fitness in a couple of light days, but you’ll lose weeks if you crash.

Endurance Zone 2 Ride – The Aerobic Engine Builder

Who it’s for:
Every runner. Seriously. Whether you’re chasing a marathon finish or just need a low-impact mileage boost, this is your go-to. Perfect for building stamina without beating up your legs. And if you’re new to cycling? This is your no-pressure entry point.

What it improves:
Zone 2 riding builds your aerobic base — the foundation of endurance performance. It boosts your heart’s efficiency, strengthens your lungs, and trains your body to burn fat as fuel. All of that adds up to stronger long runs and faster recovery between workouts.

Oh — and it’s impact-free. So you’re stacking volume without hammering your joints.

How to do it:

• Warm-up: 10 minutes of easy spinning
• Main ride: 45–90 minutes in Zone 2 (60–70% of your max heart rate)
  • That’s about RPE 4–5 — you should be able to talk in short sentences but not sing karaoke.
  • If you’re huffing, you’re going too hard.
• Cadence: 80–90 RPM (smooth, not grindy)
• Cool-down: 5–10 minutes easy spin

Start with 45 minutes and work your way up. Aim for 1–2 Zone 2 rides a week during base training — more if you’re injured or replacing easy runs.

Talk test tip: Can’t finish a sentence? You’re pushing too hard. Can chat nonstop? You’re too easy. Find that sweet spot in the middle — that “I could do this all day” rhythm.

Why it works:
Zone 2 might not feel exciting, but it’s where endurance is built. You’ll finish feeling strong, not smashed — which means you can still run the next day. Over time, you’ll ride (and run) faster at the same heart rate. That’s aerobic progress in action.

Speed Intervals on the Bike – VO₂ Max Booster

Who it’s for:
Time-crunched runners or anyone who wants to train that top gear. If you want to push your VO₂ max and raise your redline — this is your session. Perfect for sharpening fitness without trashing your legs like run intervals can.

What it improves:
Your max aerobic capacity — aka, how much oxygen you can use at full throttle. That translates to faster 5Ks, stronger surges in races, and better endurance at all paces.

Bonus: because cycling targets the muscles a bit differently, you’ll get a killer workout without the impact wear-and-tear.

How to do it:

• Warm-up: 10–15 min easy spin with 2–3 short pick-ups (10 seconds fast)
• Main Set: 6–8 rounds of:
  • 1 minute hard (RPE 9/10 — not a sprint, but dang close)
  • 1 minute easy spin (light resistance, low gear)
• Cool-down: 5–10 minutes easy

If 1 minute feels like too much to start, begin with 30 seconds hard / 30 seconds easy for 10+ rounds. Build up.

Feeling fit? Try 2 minutes hard / 2 minutes easy. Fewer reps, but deeper burn.

Why it works:
These intervals push you into the red zone and teach your body how to handle it. You’ll be breathing heavy, legs burning, maybe questioning life — but that’s where the gains live.

High-intensity work like this has been shown to boost VO₂ max fast. And unlike all-out sprints on a track, your joints get a break. It’s a smart way to add intensity without risking a pulled hamstring.

Over time, expect to feel stronger in your run workouts — especially uphill or in the late stages of races where grit matters.

Tabata Sprints (20:10 HIIT Blitz)

Who it’s for:
Busy runner? Short on time? Tabata’s your no-excuse weapon. This one’s for folks who want maximum intensity in minimum time. Perfect if you’re plateauing, need a new challenge, or just want to fry your lungs in under 20 minutes.

But fair warning: this is not beginner territory. Scale it down if needed.

What it improves:
This classic HIIT format hits both ends of the fitness spectrum—your all-out sprint power and your aerobic engine.

The original Tabata study? Six weeks of 4-minute sessions led to 28% boost in anaerobic capacity and 14% jump in VO₂ max.

For runners, that means:

• Faster recoveries between surges
• Better kick at the end of a race
• A higher ceiling overall

How to do it (Spin Bike or Trainer):

• Warm-up: 10 minutes (toss in a few 20-second efforts to prep legs and lungs)
• Find a hard gear or bump the resistance
• Go: 20 seconds full send — RPE 10+, gasping for air by the end
• Recover: 10 seconds easy pedal (or full stop if needed)
• Repeat: 8 times = one brutal 4-minute round

You’ll hate it by round 5. That means it’s working.

Full session layout:

• Warm-up: 10 min
• Round 1: 8 × 20s on / 10s off
• Recovery: 2 min easy spin
• Round 2: same
• Recovery: 2 min
• Optional Round 3 (only if you’re hitting true effort)
• Cool-down: 5–10 min

Start with just one round if you’re new. Add a second once you stop seeing stars afterward. If your third round is half-hearted? Don’t bother—quality > quantity.

During sprints:

• Keep a tall posture
• Drive hard through the legs
• Engage the core, don’t rock your upper body
• Pedal in smooth circles — push and pull

Use a Tabata timer or app — trust me, you won’t be able to count once the burn kicks in.

Do this once a week, max. Not before a long run or hard workout. Your legs and lungs will need a breather.

Hill Climb Repeats (Strength Training on Wheels)

Who it’s for:
If you dread hills on runs—or just want bulletproof legs—this is your jam. Hill repeats on the bike build climbing power, mental toughness, and muscular endurance with zero pounding on your joints.

They’re great for:

• Prepping for a hilly race
• Subbing in for a leg day at the gym

What it improves:
Targets the big movers:

• Quads
• Glutes
• Hamstrings

Plus your cardiovascular system works overtime to push against gravity (or resistance). You’ll climb stronger and run faster flat-out just from the strength boost.

Option 1: Outdoors

• Find a steady hill (5–8% grade works great)
• Warm-up, then climb 3–5 minutes at RPE 8 (hard but not maxed)
• Stay seated as much as possible — feel glutes and quads doing the work
• Stand up for 15–20 pedal strokes if you want to simulate an attack
• Use the downhill for full recovery (2–4 minutes easy spin)
• Repeat 4–6 times
• Cool down on flat roads or easy spin home

💡 Bonus: Builds “real-world” confidence for hilly terrain.

Option 2: Indoors (Trainer or Spin Bike)

• Warm-up: 10 min easy
• Intervals: 5 × 4 minutes at high resistance (60–70 RPM = uphill grind)
• Recover: 2–3 minutes between sets at low resistance
• Stay mostly seated, hands relaxed, back straight
• Add 15 seconds out of the saddle each interval to simulate a burst
• Cool down: 5–10 min

Form focus: smooth pedal strokes, full-circle motion, no wild thrashing.

How it feels:
Hard. Like hundreds of weighted step-ups — but your knees will thank you. Strength work in disguise. Expect soreness in your quads and glutes the next day, not your joints.

How to schedule it:

• Once a week is plenty
• Don’t stack it before a big long run or speed workout
• Use it as a substitute for a lower-body strength day or as a finisher on cross-training day

Recovery Spin — “The Flush Ride”

Who it’s for:
Everyone. Beginners, elites, banged-up runners, overtrained weekend warriors — everyone can benefit from this one. If your legs feel wrecked after a long run or a tough race, this is the fix. Think of it as a moving massage, not a workout.

What it does:
A recovery spin clears the junk out of your legs. It boosts circulation, speeds up muscle repair, and helps you bounce back faster — all without beating your body up. You’re not training fitness here. You’re helping your last workout sink in.

It’s the cycling version of an easy jog — only even gentler.

Studies show active recovery helps clear out lactate and soreness better than sitting on your couch. And honestly, it just feels good. I’ve used these flush rides the day after long runs, and my legs feel noticeably fresher afterward. If I ran instead, I’d just pile on more fatigue.

How to do it:
Ride stupid easy. Like, “this barely counts” easy.

• Time: 20–45 minutes
• Effort: RPE 1–2 out of 10
• Heart rate: Zone 1 (<60% of max)
• Power (if you’ve got a meter): <50% of FTP
• Cadence: Moderate to high (80–90 rpm)
• Surface: Flat pavement, bike path, trainer — whatever’s smooth and chill

You should be able to hold a conversation and breathe through your nose the whole time. If you finish and feel more tired? You did it wrong.

Coach tip: Ride alone. “Recovery rides” with friends often turn into accidental races. And avoid Strava-fueled ego traps. Average speed means nothing here — how your legs feel afterward is the only thing that matters.

Bonus Tricks to Keep It Easy:

• Ride out on a slight downhill so you cruise back slower
• Throw on a chill playlist or an easy TV show indoors
• Use the spin as meditation — focus on breathing and loosening up
• Ride on grass or trails to naturally keep your speed low

For Injured Runners:
These spins are gold. If you’re recovering from a calf, hamstring, or foot issue, but can still bike pain-free, these light rides keep the blood flowing without irritating the injury.

Just make sure your bike fit isn’t stressing the wrong area. If it hurts — stop.

Summary:
If a recovery ride feels pointless, you’re probably doing it right.

It’s not about data. It’s not about distance. It’s about letting your body breathe and reset for the next hard session.

I’ve bounced back faster from 20-milers doing a slow 30-minute spin the next day than from just sitting around.

So when in doubt? Spin easy. Recover faster.

“Ride slow to run fast.”
That’s not just a cycling cliché — it’s a recovery rule for smart runners, too.

How to Adjust Your Schedule to Avoid Burnout

Blending running and cycling is powerful — but it’s also a trap if you’re not careful. I’ve been there: stacking workouts back-to-back, thinking biking was “free” because it’s low-impact… and then wondering why I was fried and grumpy all the time.

Here’s how to do it right — without digging yourself into a recovery hole.

1. Coordinate Hard and Easy Days

This is non-negotiable. Your body doesn’t care whether the pain came from a 10K tempo or a 45-minute bike interval session — stress is stress. You can’t keep hammering.

Rule of thumb:
If today was a hard run, tomorrow is either:

• an easy spin
• a total rest day
• or a very gentle shakeout run

Same thing in reverse — hard bike today? Tomorrow’s run better be easy.

Pro coaching tip: No more than 3–4 total “intense” sessions per week, across both sports. That could be:

• 2 hard runs + 2 hard rides
• 3 runs + 1 ride
• Or whatever mix fits your goal

But once you start doing 5+ hard sessions a week, you’re not adapting — you’re just accumulating fatigue.

Rest = Gains

Don’t skip this: you get stronger from rest, not just the workout.

The work tears you down. The recovery builds you back.

So schedule rest with the same intention you plan your long runs. It’s not lazy — it’s essential.

If your resting heart rate is creeping up, your sleep sucks, and you’re irritable? That’s your body begging for rest. Not another “bonus ride.”

2. Watch for the Red Flags of Overtraining

Be your own coach. That means paying attention when your body’s waving the caution flag.

Overtraining isn’t always dramatic — it usually creeps in. If you catch it early, you can adjust and keep moving forward. But if you ignore it? That’s when the wheels come off.

Here’s what to watch for:

• Elevated Resting Heart Rate
  If your usual morning pulse jumps by 5–10+ beats and stays there for days? That’s a sign your system’s under stress.
• Chronic Fatigue
  Not “a little tired from yesterday’s workout.” This is heavy-leg, brain-fog, “I need four cups of coffee just to function” fatigue.
• You’re Slowing Down (Despite Working Hard)
  Training hard but racing slower? Legs never feel sharp? Could mean your body hasn’t had enough recovery.
• Mood Shifts
  Snapping at people? Dreading runs? Feeling anxious or flat? Overtraining hits your mood as much as your muscles.
• Sleep or Appetite Goes Haywire
  Wide awake at 2 a.m. for no reason? Appetite spiking or vanishing? System overload.
• Nagging Aches or Getting Sick More
  If little injuries keep showing up, or you’re catching every cold in town, your immune system might be waving the white flag.

Bottom line: don’t ignore these signs. Take a rest day. Drop intensity. Sub in an easy ride or chill. A few smart adjustments now can save your season later.

3. Add Volume Gradually

When you first add cycling, it might feel like free fitness. No sore legs? No problem, right?

Not so fast.

Fatigue from the bike builds just like run mileage — it just hides better.

Stick to a 10–20% increase in total training load per week.

Rough guide: 1 mile of running ≈ 3 miles of biking in training stress.

So if you’re running 30 miles a week, jumping into 100-mile bike weeks is asking for trouble. Ramp up slow and track how you feel.

4. Periodize Like a Pro

You can’t train at peak for both sports all year. That’s a fast path to burnout.

You’ve got to cycle your training focus — literally.

• Race phase? Keep the bike easy. Use it for recovery, not crushing.
• Base phase? Go heavier on the bike to build aerobic strength.
• Winter/off-season? Flip the focus. Give running legs a break.

Think of it like shifting gears. You’re not slamming both pedals at once — you’re using the right gear for the right terrain.

5. Track Your Workload (and Your Body)

You don’t need a $500 watch to train smart — just a log and some honesty.

Write down:

• Resting HR
• Sleep quality
• How you felt that day (“dragging,” “decent,” “snappy”)
• Any soreness or weird twinges

Over time, you’ll spot patterns.

Like, “Every time I do a long run followed by a hard bike session the next day, I crash.” That’s your training log giving you gold.

Apps like TrainingPeaks, Garmin Connect, or even a notes app can track combined stress. But even a notebook and three smiley faces can work if you’re consistent.

Personal Story – Less Can Be More

One runner I coached picked up cycling during a foot injury. After she healed, she tried to go full beast mode — high-mileage running and long bike sessions every week.

A month later? Wiped out and plateauing.

We pulled her back to 3 runs + 2 bike sessions + 2 rest days, and boom — energy shot up, and she PR’d a 10K within weeks.

Lesson? “More” only works when your body can handle it. Smart wins every time.

Spin Classes for Runners: Worth It? Absolutely—Here’s Why

Not into dodging traffic or crafting your own bike intervals? No worries—spin class has your back.

For runners, it’s one of the smartest ways to cross-train. I’ll admit, I used to think spin classes were just flashy music and people pretending to ride mountains. But after a few sessions, I was hooked. It’s structured, sweaty, and deceptively brutal in the best way.

Show Up, Zone In: No-Brainer Training

The beauty of spin is that you don’t have to think. Just show up and let the instructor guide the ride.

Sprints, climbs, fast flats, recovery spins—it’s all built in.

You’re not out there grinding intervals alone in a cold parking lot. You’re in a room with pumping music, someone yelling cues, and a dozen other people sweating alongside you.

You’ll push way harder than you would solo—and somehow, the time flies.

Aerobic & Anaerobic Gains, No Impact

Most spin sessions sneak in HIIT without you even realizing it. Every song is basically a new interval—hard push, recovery, repeat.

You’re working aerobic endurance and anaerobic power at the same time. Like a fartlek workout on wheels.

I know runners who hit spin hard twice a week and come back faster on the trails.

One spin instructor I trained with used to drop us all on hills—and she credited her bike sessions 100%. It’s that grinding leg strength from high-resistance intervals that makes the difference.

And here’s the best part: zero impact. You can go full-throttle without pounding your joints.

That’s a game-changer if you’re dealing with foot pain, shin splints, or just need a break from the daily run grind.

Motivation on Tap

Let’s be honest—cross-training can feel like a chore. But spin has this weird power to hype you up.

Dim lights. Loud music. One instructor yelling “Add resistance!” just as the beat drops.

Suddenly, you’re climbing out of the saddle like your life depends on it.

I’ve shown up to 6am spin classes half-asleep and left dripping sweat, fully alive, and wondering why I don’t do it more often.

If you’re someone who slacks during solo cross-training, this might be your fix.

First Spin Class? Here’s How to Crush It

1. Get There Early
Tell the instructor you’re new. They’ll help adjust your seat and handlebars. Proper fit = zero knee pain later.

2. Bring Water & A Towel
You’re gonna sweat. Like… a lot. Hydrate before, during, and after.

3. Ease Into Resistance
You’ll hear “add a turn” or “find your hill.” Don’t max out too soon. Use just enough tension to feel it without bouncing in the saddle.

4. Push Outside the Comfort Zone (But Don’t Die)
Sprint when the group sprints. Climb when the beat drops. But if your lungs are in revolt? Back off. You’ll get stronger every class.

5. Nail Your Form

• Don’t death-grip the bars
• Shoulders relaxed, core tight
• When standing: hips back slightly, smooth pedal strokes
• Think “circles with your feet,” not piston mashing

These tweaks go a long way in avoiding soreness where you don’t want it (like your back, wrists, or knees).

6. Let It Be Fun
The first class might feel like a punch in the gut. But once you get the flow, it gets addictive.

The music, the group, the sweat—it starts to feel like a celebration of effort.

A break from pounding pavement, but still tough as hell.

Are Spin Classes Worth It for Runners?

Short answer? Yes. If you use them right.

Spin classes are one of the best bang-for-your-buck cross-training tools for runners—especially if you struggle with motivation on solo rides or want to cycle without messing with traffic and bike maintenance.

You get a killer workout in a controlled setting, no matter the weather, no gear needed. Just show up and get your sweat on.

And let’s be honest—on days when the idea of one more treadmill run makes your soul groan, a good spin class with thumping music can shake you out of the monotony and give you that endorphin rush you didn’t know you needed.

Why Spin Works for Runners

• Built-in intensity: The class structure forces you to push when you might otherwise coast.
• Safe and accessible: No road hazards, no helmet, no clipped-in panic.
• Cadence booster: Spin naturally emphasizes faster leg turnover, which can carry over to your running.
• Time-efficient: You can squeeze in 45 minutes of focused cardio without overthinking it.

Some marathoners even use spin classes as recovery rides. It pumps blood to your legs and helps flush out soreness without the pounding. Just be smart about where it lands in your training week.

One Caution: It’s Still a Hard Workout

Don’t let the dim lights and pop music fool you—spin can wipe you out just as fast as a tempo run.

Slot it in like you would any hard session. That means:

• Don’t spin hard the day after intervals
• Don’t treat every spin like a race
• Give yourself time to recover

Many spin instructors teach multiple classes a week—but most of us aren’t built for that load. Respect the effort, and your legs will thank you.

Pro tip: Nervous about your first class? Pick a bike in the second row. You’ll see the instructor and experienced riders without feeling like you’re on display. And truthfully—everyone’s too busy sweating to care what you’re doing.

The Bike Saved My Running

I didn’t believe in bikes until my body forced me to. Too many aches. Too many breakdowns. I finally caved and clipped in.

And here’s the truth: cycling made me a better runner.

My stride got smoother. My legs got stronger. My recovery improved. And my motivation—after years of burnout—finally came back.

Recap: Why Cycling Helps Runners

• Less impact, more aerobic volume
• Builds stronger glutes and quads (hello, better hill running)
• Fights burnout with variety
• A recovery tool that actually works
• Cross-trains muscles you didn’t know were weak

You don’t have to go full “cyclist.” You don’t need Lycra kits or carbon bikes. Just swap one weekly run for a ride—outdoors, spin class, whatever you’ve got.

Even one low-key ride per week can unlock better recovery and a fresher mind. Add a second, and you might start noticing faster paces on fewer running days.

Your Move

Still skeptical? That’s fair. But consider this your nudge:

• Try one spin class this week
• Or hop on the gym bike for a 30-minute low-key session
• Or borrow a friend’s bike and go chase some wind

You might be surprised at how different—but good—your next run feels.

Running and cycling aren’t rivals. They’re teammates. Use both, and you’ll be stronger, more resilient, and probably a lot less banged up.

Let’s get to it!

What Is a 50K Ultramarathon?

Let’s start with the basics.

A 50K is an ultramarathon, which is just a fancy way of saying it’s any race longer than a 26.2-mile marathon.

In miles, that’s 31.07 miles.

It might sound intimidating, but trust me—50K is often the first ultramarathon distance that new ultra-runners tackle.

The “feel” at ultras is totally different from a road marathon.

Picture less of that ‘big city race’ feeling and more of an ‘adventure on the trails’ kind of vibe.

Many 50Ks are run on trail courses, which means you’ll probably be jogging up mountains, sloshing through mud, and hopping over roots or scrambling across rocks.

Let me explain what I mean…

Not yet ready for an ultra? Try my marathon plan.

Trail vs. Road Challenges

Now, if you’re coming from road marathons, here’s the kicker: trail ultras are a whole different beast.

Road marathons are usually spot-on in terms of distance and pace. Aid stations hand out gels and water every few miles.

In trail ultras, things get… wild.

A “50K” might actually turn out to be closer to 55K or 56K. Surprise, right? And the terrain? It can slow you down big time.

Take my experience in the Bromo Desert Marathon 50K, for example. Instead of running on smooth, flat roads, I found myself tackling volcanic sand dunes and steep climbs at high altitude.

One minute, I was running, and the next, I was power-hiking up a freaking crater! Trail ultras often demand that you slow down or even take hiking breaks—especially on those steep uphills.

And that’s totally fine! Walking breaks? Yeah, they’re actually part of a smart 50K strategy. That’s why ultra trail runners are often dubbed power walkers – we do more walking than running, truth be told.

The trails are unpredictable—rocks, mud, rivers, crazy weather. You’ve got to be ready for anything. But that’s what makes ultramarathons so much fun—just the adventure of it all.

Elevation = Extra Challenge

Let’s talk about elevation for a second. Many trail 50Ks come with some serious vertical gain. We’re talking hills, hills, and more hills. And it can make a HUGE difference in your race.

Here’s a trick: for every 100 meters of climbing, you can think of it like adding a whole kilometer to the effort. So, if you’re doing a 50K with tons of elevation, it could feel like running a much longer race.

During my Bromo Desert 50K, I had almost 1800 meters of climbing. Compared to other events, the elevation isn’t too much but for a first-timer, I’d to be careful and pick a a beginner-friendly ultra event (more on this later).

And it took me hours longer to finish than it would have on a flat course.

But that’s the deal with trail ultras—terrain and elevation make all the difference, so don’t worry too much about pace. The goal is to keep moving and take in the scenery. It’s all part of the experience.

To give you an idea, here’s the course profile for the bromo 50K event:

P.S Yes, that’s me being featured on the main page of the website. Famous right? Na. Just by accident

50K Race Times: World Records and Average Joes

Now, you might be wondering—how fast can 50K runners really go? Let me tell you, the pros make it look easy (even though it’s anything but). The men’s 50K world record? That’s CJ Albertson, who ran it in 2:38:43—31 miles at a crazy-fast 5:07 per mile pace! And for the women, Desiree Linden set the record at 2:59:54—she was the first woman to break 3 hours for a 50K. That’s insane!

But let’s be real here, that’s elite level. For most of us regular folks, a 50K is gonna take a lot longer than that. A solid amateur might finish in 5 to 6 hours on a good day.

Most people? They’re looking at finish times in the 6 to 7-hour range. And that’s totally okay! In fact, most 50Ks have 8-10 hour cut-off times, and plenty of runners take the full time to finish.

And here’s a fun fact: ultramarathons? Experience counts for a lot. Peak performance for a 50K tends to hit around 39-40 years old. So even if you’re not in your 20s, there’s a good chance you’ll be getting faster as you age!

P.S. Please keep in mind that these world records were performed on road, usually on indoor tracks. Not your typical trail course with elevation and treacherous terrains.

Trail vs Road Times

If you’re coming from marathons, expect to be slower in a 50K. It’s normal to run each mile 10 to 30 seconds slower than your marathon pace, even on a good day.

For example, if you run 8:00 minute miles in a marathon, your 50K pace might fall around 9:00-10:00 per mile.

That might add another hour or so to your time.

If the trails are technical or hilly, add more time to that.

For my first 50K took me about 8 hours, even though I had run a 3.5-hour marathon before. The sandy dunes, the slippery hills, the scorching heat and the mental aspect of running beyond 26.2 miles made it a whole new challenge.

Remember this: in ultras, it’s not about finishing fast. It’s about finishing strong.

Don’t stress about your time. As a first-timer, the main goal is to get across that finish line with a smile on your face.

And hey, sometimes being on the trail longer just means more time to fuel up, enjoy nature, and soak it all in.

Training Principles for a 50K Ultramarathon

Training for a 50K is a lot like marathon training, but with a few extra challenges thrown in.

The main things you need to focus on are building your endurance (lots of mileage and those long runs), running on terrain that matches race day, taking recovery seriously, and getting used to being out there for hours.

Let’s break it down into some solid principles.

Build Your Mileage Base (Consistency is Key)

To finish 31 miles, you need to have a solid base.

This isn’t about cramming in a few massive workouts. It’s all about consistency.

Start slow and build up gradually. Think of it like this: the more time you spend running, the more you teach your body and mind to handle the long hours on the trails.

Before your 50K, aim to reach a peak mileage of 50-60 miles per week. This isn’t a one-week wonder — it’s about steadily increasing your mileage until your body is ready to handle it.

If you’re just getting started and are newer to running, it might take up to a year of steady training.

But if you’re already running around 40 miles a week, six months of focused ultramarathon training should get you there.

Don’t stress about speed work for your first ultra. Throw in some strides or tempo runs for variety, but the real focus is just time on your feet.

One ultramarathon coach put it this way: “A 50K is a slower marathon.” The basic principles are the same as marathon training, but your focus should be on time on your feet, handling terrain, and fueling during those long runs.

My best advice?

Your first goal for a 50K? Simple — just finish. Forget about setting time goals. Your main focus is building that base and staying healthy. The biggest mistake I see in rookies is ramping up miles too quickly and ending up injured or burned out. Stick to the classic “10% rule” or listen to your body — increase gradually, and don’t forget to take recovery weeks when needed.

The Long Run 

Long runs are your bread and butter for ultramarathon training.

They’re going to feel like your best friend and, at times, like a challenge you want to throw out the window. But no matter how hard they get, these long runs teach your body how to keep going when it feels like it can’t.

For marathons, long runs peak around 20 miles, but for a 50K, you’re going to stretch that further.

Aim for your longest run to be between 20 and 26 miles. Some plans even recommend running a full marathon as part of your training. But honestly, hitting 20-22 miles is plenty, especially if you’re doing back-to-back long runs (more on that later).

When I was gearing up for the CTC 50K, my longest training run was 24 miles on trails, and it took me nearly 5 hours.

It was exhausting, but it gave me serious confidence: “Okay, I can handle being on my feet for hours.” Those first long runs will break you down, but they’ll build you up too.

I’d break the run into mental chunks: “Just get to the next mile,” “Make it to the top of this hill,” “Just reach the next water stop.” It made those long, grueling hours feel a little more manageable.

Back-to-Back Runs:

One trick I used in my training was back-to-back long runs.

For example, I’d do a long 18-mile run on Saturday and then follow it up with 10-12 miles on Sunday.

It was tough at first, but it simulated running on tired legs — which is basically what an ultra feels like. A good rule of thumb from coaches is to get in 30-40 miles over two days when you’re training for a 50K.

That one weekend where I did 20 miles on Saturday and 12 miles on Sunday really changed my mindset.

Sunday’s run was tough at first, but I realized I could still keep going on tired legs — a huge confidence boost for race day because when you hit that halfway point in an ultra, your legs are already begging you to stop.

Train on Terrain (Hills & Trails are a Must) 

If you’re training for a 50K trail race, here’s a piece of advice that’ll make all the difference: train on terrain that’s as close as possible to your race.

If your race has mountains, then find hills.

If it’s a technical trail, look for some gnarly paths to run on.

Running on trails isn’t the same as pounding pavement—it’s a whole different ball game.

You’ll be using muscles you never knew you had (I’m talking about those stabilizers and your ankles). It’s tougher, and your body’s going to feel it, so it’s important to get it used to the challenge.

When I was gearing up for Bromo, I didn’t just run any trails—I sought out the steepest, most challenging ones I could find. I even did hill repeats on a local trail until I was crawling up it.

But you know what? That paid off big time on race day when I faced those endless climbs. Train the way you race—it makes all the difference.

Now, let’s talk hills. When you’re facing big climbs in training (or race day), hiking is completely fine. In fact, it’s often the best way to get up those steep sections without burning out.

During my second ultra, the CTC 50K, the hikes were much more brutal. During the event, my mantra became: hike the ups, run the flats and downs.

Whenever I saw a big hill coming, I gave myself permission to power-hike it.

Guess what? I passed a lot of folks who tried to run up those hills, only to blow up halfway.

And don’t forget to train for those “extras” you might encounter on race day: running in the dark (ever tried a night run with a headlamp? If your race starts early or like CTC, at 10 PM, this is a must ), running in the heat, or even training in sand if your race happens in the desert. The more familiar race day feels, the better.

If you’re running a flat road 50K, don’t worry about the major elevation training, but still try to get in some soft-surface runs. You want to reduce the pounding on your legs. And yes, make sure you’re doing some long runs on flat pavement so your legs get used to that constant repetitive motion. You’ll need it come race day.

Recovery: Rest Hard, Run Hard 

Let’s face it, ultra training is no joke.

It’s tough on your body. As you increase your mileage and long-run distance, recovery becomes just as important as the training itself. You’re pushing your muscles, joints, and even your immune system to the limit, so you need to prioritize rest just like you do with your runs.

Here’s what I’ve learned about recovery that keeps me coming back stronger:

• Sleep: Aim for 8+ hours of sleep per night. Your body does most of its repair work while you’re asleep. I always treated sleep like it was part of my training. Honestly, it’s the easiest “workout” ever. All you have to do is nothing, and your body gets stronger for it.
• Rest Days: Take at least one or two rest days a week. No running, no excuses. Let your legs fully recover. If you need to move, go for a gentle walk or do some stretching or yoga. But don’t push it on rest days.
• Listen to Your Body: If something feels off or you’re dealing with a nagging pain, don’t just push through it. Take a step back if you need to. I learned this the hard way after running through Achilles pain. I had to take an unplanned week off, and it wasn’t fun. Now, I respect rest like I respect my longest runs.
• Nutrition for Recovery: After those long runs, you need to refuel. Your body needs protein and carbs to rebuild those muscles. For me, a big smoothie or a solid meal always hits the spot. My go-to recovery snack is chocolate milk and a turkey sandwich—simple, but it works every time.

Put It All Together: A Sample Week 

To give you an idea of what a peak training week might look like for a 50K, here’s what it could look like:

• Monday: Rest or easy cross-training (yoga, cycling, etc.)
• Tuesday: 5-mile easy run
• Wednesday: 8-10 mile run (moderate pace, maybe add in some hills or tempo work)
• Thursday: 5-mile recovery jog (super easy pace)
• Friday: Rest day
• Saturday: Long run – 20-22 miles on trails, go slow, and practice fueling
• Sunday: Second long-ish run – 10 miles easy (on tired legs from Saturday)

This comes out to about 50 miles for the week. The next week, you might cut back for a “down week” to recover, then build back up again. Everyone’s plan will vary, but the key parts are: one long run, maybe a back-to-back, and mostly easy-paced running.

Training for a 50K isn’t just about logging miles. It’s about listening to your body, training smart, and putting recovery just as high on the list as the running. You’ve got to run hard, but you’ve got to rest hard, too.

Hydration

Start early when it comes to hydration. Drink consistently throughout the race, not just when you’re thirsty. I made this mistake early on, but it’s especially important if it’s hot, like it was during my Bromo Desert 50K, where temps hit 30°C (86°F). I drank about 500-750 ml of water per hour and carried electrolyte tablets to avoid dehydration and cramping.

But here’s the key: Don’t overdo it. Too much water can actually be harmful. There’s something called hyponatremia, and you definitely don’t want that. So, listen to your body. Drink when you’re thirsty, but don’t drown yourself. Keep sipping, stay ahead of your hydration, and you’ll be good.

Practice Your Fueling in Training

The best time to figure out your fueling strategy is during your long runs. I practiced with gels, bars, and electrolytes every 30 minutes during a 20-mile training run. By the time race day came around, I knew exactly what my stomach could handle. And trust me, there’s nothing worse than trying to figure out your fueling plan during a race.

Test everything during training. Your body will thank you when race day comes around.

Gear Essentials: What You’ll Need for a 50K

Gear can make or break your race. After my first ultra, I knew exactly what I needed to feel comfortable and get through the race. Here’s the gear I swear by:

• Trail Running Shoes: You need the right shoes for grip and support on rocky, uneven terrain. Don’t make the mistake of showing up with shoes that aren’t broken in. Trust me, you don’t want blisters on race day.
• Hydration Pack or Belt: You’ll need to carry your own water and snacks. Aid stations might be spaced out, so a hydration vest or belt is your best friend.
• Headlamp: If your race starts early or ends late (like my CTC 50K did), you’ll need a headlamp to see where you’re going.
• Clothing: Moisture-wicking clothes are a must. You want to stay dry, not drenched. Bring a jacket or vest just in case the weather changes.
• Electrolyte Supplements: I always carry electrolyte tablets to keep my sodium and potassium levels in check. These really help prevent cramps.

Don’t forget a small first-aid kit, sunscreen, and chapstick. Trust me, those little things go a long way on race day.

Start Slow, Finish Strong

Here’s something I can’t stress enough—start slow. I know the race day excitement makes you want to go fast, but ultramarathons aren’t sprints. When I ran my first 50K, I took it easy at the start, and it paid off. I didn’t burn out in the first half, which gave me enough in the tank to pick up the pace later.

On the downhills, push the pace. On the uphills, take it slow—don’t be afraid to hike. It’s all about pacing. The key to finishing strong is managing your effort. Walk when you need to, and make sure you’re not going too hard early on.

Remember my mantra: hike the ups, run the flats and downs.

Pace Yourself: “Be the Fastest Tortoise”

When you’re gearing up for a 50K, forget obsessing over mile splits like you would in a marathon. Here, it’s all about the effort. There’s this saying in the ultra world: “Be the fastest tortoise.” Start slow, and try to keep it that way. You’re not racing to set a record in the first few miles – you’re setting yourself up for the long haul.

Run by Effort, Not Pace

For me, trail ultras are all about listening to my body. Sometimes I wear a heart rate monitor, but it’s mostly about the feeling. I use RPE (Rate of Perceived Exertion) – if I can talk, I’m in the sweet spot. If I’m gasping for breath, I dial it back. I want to save my energy for the long grind.

During my first 50K, I kept reminding myself: “If it feels slow, slow down some more.” I know, it sounds counterintuitive, but it works. During the CTC 50K, I saw a ton of runners take off like they were in a sprint, only to fade hard later.

I stuck to my plan, kept it steady, and ended up passing a bunch of those same runners in the second loop. Slow and steady? Definitely wins the race.

Pacing Mantras That Keep You Going

I’ve got a few mantras that keep me grounded on race day:

• “Your slowest pace matters more than your fastest.” This one’s big. You’re in it for the long haul, so don’t blow yourself out in the first few miles just to impress anyone. Keep it steady, and you’ll stay stronger longer.
• “Race the second half.” This one’s my favorite. I don’t push for speed until I’m well past the halfway point. In the first half, I let others zoom past. But come the second half? If I’ve still got legs under me, I start reeling people in. That’s when it’s really fun.

The Bromo Desert had two big loops, and I was pacing myself by walking the steep climbs and taking the downhills at a light shuffle. The first loop, I watched people zoom ahead, and I could feel the temptation to chase them.

But then I heard my coach’s voice in my head: “If it feels slow, slow down some more.” That advice saved me. By the second loop, I was passing runners who had started too fast.

Embrace the Ultra Mentality

Let’s face it: Ultras are mostly mental. While 50Ks might be 10% physical, that other 90% is all about your mind.

There will be moments when you’re feeling beat up and questioning why you’re out there. But this is where the mental game is won.

Here’s how I push through:

• Break it down into sections: Looking at the full 31 miles can be overwhelming. Instead, focus on small wins – the next aid station, the next gel, the next mile. I’ve done long runs where I just told myself, “Get to the next hill.” That’s all you need to think about.
• Positive self-talk: Sounds cheesy, but trust me, it works. I’ve used mantras like “One foot in front of the other” or “You’ve got this” when things get tough. I remember mile 28 during the Bromo Ultra – I was running on fumes, and all I could think was, “You didn’t come this far to only come this far.” It kept me going.
• Expect the lows, but know they’ll pass: There will be times when you feel like absolute garbage. But, just like life, things change. I hit a serious low during the CTC Ultra at 3 AM. The rain was pouring down, my headlamp failed me, my legs were wrecked, and I was exhausted. I told myself, “Just make it to the next aid station.” Once I got there, I had some hot Indomie (noodle soup), a little Coca-Cola (honestly, magic), and I was back on my feet.

Final Thoughts – You Can Do This! 

Training for a 50K is a journey, no doubt. There’s no magic shortcut – just time, patience, and the grind. It’ll challenge you physically and mentally, but trust me, you’ll come out stronger than ever. Remember: it’s about consistency. Even when it sucks, just keep going. When you cross that finish line, you’ll know it was all worth it.

I’ll never forget the Bromo Desert 50K. I was nervous as hell at the start – doubts swirling in my mind. But once I settled into my rhythm, I was in the zone. I finished exhausted but proud, with a grin on my face. And honestly? It was one of the best feelings ever.

And you? Whether your goal is just to finish, or to crush it, your 50K will be one of the most rewarding experiences you’ll ever have. Let’s go – get out there and start training. You’ve got this.
