How Many Miles Can You Run Without Losing Muscle?

by

Let’s set the record straight.

Running alone doesn’t torch muscle like people love to fear-monger. The body’s main fuel sources are carbs and fat.

Unless you’re doing back-to-back marathons with zero calories in you, your muscle isn’t going anywhere fast.

In normal conditions—well-fed, running under 90 minutes—you can log your miles without watching your muscles disappear.

That whole “running kills gains” myth? It’s lazy thinking.

The real culprits are poor recovery, lack of strength work, and under-eating.

Let’s dig into what’s really going on—and how to protect your strength.

Does Running Really Burn Muscle?

Runners often ask me: “Will running make me skinny and weak?” And I get it.

No one wants to lose their squat PR just because they’re chasing a sub-20 5K.

Here’s the science-backed truth: running itself isn’t a muscle destroyer.

As long as you’ve got glucose in your system, your muscles won’t be touched.

That’s what a Runner’s World nutrition expert points out—carbs come first. But once you torch through all your glycogen—say you’re fasting or running for hours without food—then yeah, your body might dip into muscle protein for fuel.

Let me rephrase it.

Running under 90 minutes while properly fueled won’t cost you muscle.

But go past that point, especially without carbs, and your body starts getting creative: it taps into fat and even breaks down muscle fibers to keep going.

That’s “hitting the wall” in real-time.

And don’t forget about cortisol—that sneaky catabolic stress hormone.

Go too hard, too long, too often, and cortisol shoots up.

A study from the Journal of Exercise and Nutrition showed elevated cortisol after long cardio sessions, which encourages muscle breakdown.

That means if you’re constantly running on empty, stressed, and skipping meals—yeah, your muscle will suffer.

Why Runners Lose Muscle

Let’s be real—it’s rarely the miles alone that do the damage.

It’s the combination of:

  • Low fuel and calories: If you’re under-eating or running fasted, you deplete glycogen. Once that’s gone, your body pulls from muscle for fuel. One study even showed muscle protein breakdown doubled when athletes trained in a carb-depleted state.
  • High cortisol & inflammation: Long runs and brutal workouts crank up cortisol, and if that hormone stays high (especially with poor sleep and life stress), it leads to more muscle loss.
  • No lifting stimulus: Muscle needs a reason to stay. If you ditch the gym and go full-cardio, your body stops “seeing the need” for lean mass. It’s the classic “use it or lose it” deal.

This is why I tell every runner I coach: Don’t blame running. Fix your food. Fix your lifting. Fix your recovery.

How Much Running Is “Too Much” for Muscle?

There’s no perfect number, but from experience—both personal and with clients—here’s how I break it down:

  • 10–25 miles/week: You’re safe. Eat right and lift, and you’ll stay lean and strong. Great for general fitness.
  • 25–50 miles/week: Here’s the tipping point. You’ll gain running fitness, but only if you stay on top of nutrition and recovery. I can hang around 30–35 with no issues, but only if my diet is locked in.
  • 50+ miles/week: Now we’re in elite territory. At this point, recovery becomes a job. You need 8+ hours of sleep, plenty of food, and 2–3 strength sessions weekly to maintain muscle. Most people skipping any of these will shrink over time.

Personal note: My sweet spot is 25–30 miles/week with two lifting sessions. Once I pushed past 40, it felt like my muscles were rebelling—my lifts dipped, I lost fullness, and I felt like I was chasing fatigue every day.

Warning Signs You’re Losing Muscle

If you’re running a ton and starting to feel… off. I know most of these are dead giveaways, but here’s what to watch for:

  • Flat muscles: No post-workout pump, especially in upper body. Shirts feel looser.
  • Strength dips: You go to bench, and your old weight feels like a max attempt. Rows, squats, pull-ups—everything just feels heavier.
  • Chronic fatigue: You’re tired even after rest days. Legs feel heavy. Mind feels foggy. Recovery is slow or nonexistent.
  • “Skinny-fat” weight loss: You drop scale weight, but your body looks softer or less defined. You’re not losing fat—you’re losing mass.

And it’s not just anecdotal.

One study on marathoners found significant muscle protein breakdown in those who ran full-distance.

The damage was measurable—and it matched what I see in runners who push too hard without a plan.

10 Ways to Run Without Losing Muscle

This is for my fellow runners who don’t want to look like a deflated balloon after upping their mileage.

You can run strong and stay jacked—if you’re smart about it.

Here’s how I (and the athletes I coach) pull it off.

1. Lift Heavy Twice a Week—No Excuses

When my running load goes up, I don’t quit lifting—I just trim it down.

I hit full-body compound lifts twice a week, around an hour each. Think squats, deadlifts, rows, bench—all the good stuff.

I’d also recommend sticking to the 4–10 rep range to help keep that muscle-building signal strong.

Check some of my guides:

2. Eat a Bit More Than Maintenance (On Purpose)

Back in the day, I thought eating less would make me a faster runner.

Instead, I felt like I was dragging a sandbag through every mile.

Here’s the truth: if you’re trying to build or even just keep muscle, running on a calorie deficit is a bad idea.

These days, I bump up my intake by about 200 calories on heavier weeks.

So I add a snack or pile my dinner plate a bit higher—not to bulk up, but to recover properly.

3. Protein = Non-Negotiable (1g per Pound)

This is one hill I’ll die on.

If you want to keep muscle while running, you have to hit your protein target.

The American College of Sports Medicine suggests 0.5–0.9g per pound. I go higher—closer to 1g per pound, especially on training days.

At 165 pounds, that means I’m getting 165–180g protein.

It sounds like a lot, but once you’re in the habit—chicken, eggs, Greek yogurt, whey shakes—it adds up fast.

I even stash jerky and yogurt in my bag so I’m never caught without fuel. Marathon Handbook backs it: no protein, no muscle repair.

4. Don’t Run Long on an Empty Stomach

I used to think fasted runs were hardcore.

Then one morning during a 2-hour run, my legs started shaking so bad I had to sit down on the sidewalk. Never again.

Running long without fuel forces your body to break down muscle for energy.

Runner’s World confirms it.

Now, before any run over an hour, I eat something with carbs and protein—like oatmeal and a scoop of whey or a banana smoothie.

It’s simple, but it makes all the difference.

5. Fuel During Runs Over 60 Minutes

If you’re going longer than an hour, don’t just bring water.

Your body needs carbs to keep going—and to protect your muscle.

Most experts suggest 30–60g of carbs per hour.

I used to skip this. Big mistake.

On one 2-hour run in college, I bonked hard with nothing but water. These days, I start fueling around mile 7 with gels or sports drinks.

My energy stays up, and my muscles don’t get chewed up for fuel.

6. Don’t Stack Hard Lifts and Hard Runs

I’ve tried squatting right after a tough track session.

My legs felt like overcooked noodles—and the next day, I was useless. Lesson learned.

Now I space things out.

If I run in the morning, I’ll lift in the evening. Or I alternate days.

That way, each session gets the energy and focus it deserves.

If you have to double up, eat a solid meal in between.

7. Sprints and Hills Keep Your Legs “On”

All that slow, steady mileage won’t kill your muscle—but it won’t grow it either.

That’s where sprints come in.

Short, explosive work lights up your fast-twitch fibers—the ones that grow.

Once a week, I add short hill sprints (8×15 seconds) after my run.

The ASICS muscle-building guide says these sprints send a stronger growth signal than long, easy runs.

I’ve found they keep my legs looking and feeling powerful—even deep into marathon training.

8. Sleep Hard, Stress Less, Recover Like You Mean It

Muscle builds while you rest, not while you grind.

I protect my sleep like it’s part of my training.

On high mileage weeks, I shoot for 8+ hours a night in a dark, quiet room.

Years ago, I thought I could survive on 5 hours.

Didn’t take long for my workouts to fall apart.

Now? Naps, off days, and chill time are part of my routine.

Less stress = less cortisol = better recovery.

9. Take the Right Supps (Creatine, Whey, D, Omega-3s)

I don’t chase every magic powder, but some supplements are worth it.

Creatine is one of them.

It helps with power, recovery, and keeping your muscles full—even if you’re logging long miles.

I take whey protein daily and keep fish oil and vitamin D in rotation.

When Bali’s heat starts draining me, creatine helps me stay on top of hydration and muscle volume.

These aren’t miracle pills—but they do help me bounce back faster.

10. Refuel Fast After Tough Runs

That post-run window? Still matters.

I try to get carbs and protein in within 30 minutes.

A quick shake, chocolate milk, banana and Greek yogurt—doesn’t have to be fancy.

Studies say this kickstarts recovery and helps muscle rebuild faster.

Personally, I’ve felt the difference.

If I refuel fast, I’m ready to hit the gym or trails again the next day.

If I wait? Everything feels heavier.

Coach’s Note:

Every one of these tips saved my gains at some point.

One time I skipped pre-run fuel (mistake #4), and I was wrecked for two days.

These aren’t just theories—they’re hard-earned habits. Use them.

Weekly Hybrid Plan: How I Balance Lifting & Mileage Without Falling Apart

Here’s a weekly setup I’ve used (and coached others through) to juggle both strength and running.

It’s not magic — just consistency and smart sequencing. You can tweak the mileage and lift intensity based on your current shape, but don’t mess with the structure too much.

  • Monday – Upper-body strength (45 min) + short easy run (3–5 miles)
  • Tuesday – Rest or active recovery (mobility, yoga, walk the dog)
  • Wednesday – Medium run (6–8 miles steady or tempo) + core work
  • Thursday – Lower-body strength (45 min) + optional shakeout jog
  • Friday – Short run or full rest + light mobility (think foam roller and breathing work)
  • Saturday – Long run (10–15 miles — fuel mid-run)
  • Sunday – Full recovery: sleep, stretch, eat extra protein

This setup gives me two strong lifting sessions, spaced out enough to avoid frying my legs before long runs. And it works.

One of my clients who followed a plan like this told me, “I didn’t just keep my muscle — my running actually felt easier because I was stronger.”

That’s the sweet spot.

💡 Want to shift days? Go ahead.

Maybe you move Sunday’s rest to Friday, or flip strength to Tuesday. Just don’t cut the lifting entirely. That’s where runners mess up.

Quick Story

I train in phases.

When I’m deep in a run block, I’ll ramp up to 35–40 miles a week and keep strength work light — maintenance mode.

In a lift block, I’ll drop mileage to 15–20 and go heavier in the gym.

This toggling helps me build both engines — strength and endurance — without burning out either.

When Running Eats Your Muscle Alive (Yes, It Happens)

Let’s talk truth.

Running can absolutely chew through muscle if you’re not paying attention.

Here are four ways runners sabotage their gains:

1. Running on Fumes (Big Calorie Deficit)

This one burned me hard.

I tried intermittent fasting while running 30+ miles a week. Dumb move.

I dropped 4 pounds — not of fat, but muscle.

Your body isn’t a fan of starvation cardio.

If you’re not eating enough (especially post-run), it’ll tap into muscle to stay upright. Don’t let that happen.

2. Going Long & Fasted

Ultrarunning on an empty stomach? That’s a muscle massacre.

Anything over 60 minutes while fasted turns catabolic.

You might feel “disciplined,” but your body’s just tearing itself down for fuel.

If you’re cutting weight or skipping breakfast often, beware.

3. Ditching Lifting Altogether

Tried a 30-day “no weights” challenge once — only running.

Week one? Felt light and zippy.

Week four? Shoulders disappeared, and my legs had no pop.

That strength loss is real.

If you’re not giving your body a reason to keep muscle, it won’t.

4. Overtraining + No Recovery = Disaster

Running hard daily, skipping sleep, and stressing like crazy?

Welcome to cortisol hell.

I saw it in a buddy training for an ultra — 70 miles a week, sleeping 5 hours a night.

By week six, he looked like a skeleton.

We had to reset everything: food, sleep, recovery. He eventually bounced back, but barely.

🧠 Moral of the story: Muscle loss isn’t random. It shows up when you stop feeding, lifting, or resting right.

Nail those three, and your strength will stick around.

Real Talk FAQs: Muscle Gains While Running

Q: Can you run every day and still gain muscle?

Technically? Maybe. Practically? Probably not.

Daily running with no rest crushes your recovery window. Even elite pros don’t go 7-for-7 year-round.

If you’re lifting and fueling like a beast, 5–6 running days can work — especially if two are sprint or strength-focused.

That’s my current setup: six running days, but two double as leg days or speed work.

Q: Is 30 miles a week too much for muscle?

Depends on how you run it.

30 miles of easy runs + smart eating? That’s a green light.

But 30 intense miles + bad sleep + low protein? That’s where hypertrophy dies.

I consider 30 miles the upper limit for lifters trying to stay lean and strong.

Key is recovery — and not turning every run into a hammer session.

Q: Is HIIT safer for muscle than slow jogging?

Absolutely.

Sprint work and hill repeats spike hormones like HGH and testosterone.

Long, slow runs? They can signal your body to go into “lean machine” mode — great for endurance, but not muscle.

That’s why sprinters look jacked and marathoners look… well, you know.

Toss in some explosive efforts if muscle matters to you.

Q: Should I drink a protein shake after running?

Yes. Especially after long runs (60+ minutes).

I chug a shake with 25–30g of protein and a bit of carbs — chocolate milk or whey smoothie, whatever I can stomach.

I don’t always feel like it, but trust me, the next day I’m less wrecked.

Timing is key: shoot for 30 minutes post-run.

Even a banana + two boiled eggs beats waiting hours.

Q: Best pre-run meal for muscle maintenance?

Combo of carbs + protein, but keep it light.

Toast with peanut butter and banana. Oats with fruit and a scoop of whey.

Something to top up glycogen and give you amino acids before you hit the road.

If I’m running early, half a shake and a banana 30 minutes before is enough to keep my body from raiding muscle for fuel.

Final Thoughts: You Don’t Have to Choose

You can keep your miles and your muscle.

You just have to train smarter, not harder. Run like a runner. Lift like a lifter. Eat like an athlete.

As someone who runs trails in Bali, lifts heavy twice a week, and has coached dozens through this balance, let me tell you — the two don’t cancel each other out.

They make each other better.

You just need a plan and the discipline to stick with it.

My rule? Track your strength like you track your pace.

If your lifts start sliding or your legs feel like noodles on the run — it’s time to reassess calories, sleep, or lifting frequency.

To my younger self:

Let some muscle go in base phase if you’re chasing a running PR.
But earn it back with a strength block after.

Always eat like your training matters — because it does.

You can run strong.
You can stay strong.
Just don’t wing it.

Why Does My Throat Burn When I Run?

by

Suffering from burning throat while running? Then worry no more.

As a coach, I’ve seen this over and over. Doesn’t matter if you’re brand new or have been running for years—this kind of throat burn can sneak up on anyone.

The good news? There are clear reasons behind it. And even better? There are real, doable fixes.

Whether it’s how you breathe, the weather, what you ate, or how hydrated you are—each piece can be worked on. No rocket science here—just practical stuff that works.

So in this article, I’ll walk you through exactly why your throat burns when you run—and more importantly, how to stop it.

I’ll break it down using science, stuff I’ve seen in my own coaching, and yes, even tips from from different coaches and sources.

By the end, you’ll know what to tweak so you can focus on the good part: actually enjoying your run.

1. Mouth Breathing & Overexertion 

Let me be straight—I used to start every run like I was racing the clock. Way too fast.

Within minutes, I’d be gasping through my mouth, and my throat would feel like sandpaper.

Mouth breathing seems like the natural go-to when you’re pushing hard, but it’s also a fast track to that raw, dry, burning throat.

Here’s the problem: your nose is built for breathing. It warms and moistens the air before it hits your lungs.

Your mouth? Not so much.

And please don’t take my word for it.

According to study, nose breathing is better during exercise exactly because it filters and humidifies the air. Mouth breathing skips all of that and brings in cold, dry air.

That’s what dries your throat out and makes it sting.

And here’s something I’ve noticed as a coach—when you’re mouth breathing, it often means you’re going too hard too early.

One Reddit runner nailed it: “If your throat burns a few minutes into a run, you’re going too fast.”

I agree. If you’re struggling to breathe or talk early on, you’ve got to dial it back.

I always say: run smart, not just hard. The goal isn’t to finish gasping—it’s to build a rhythm.

Try running at a conversational pace—if you can say a sentence without sucking wind, you’re doing it right.

One tip from the running community? Make sure you can talk for at least 80% of your run. It’s basic, but it works.

Once you’ve got your pace under control, start paying attention to how you breathe.

Try this: breathe in through your nose, out through your mouth—especially during warm-ups or easy runs.

At first it might feel weird (I used to feel like I had a cold even when I didn’t), but your body adjusts. And it’s worth it.

Less throat burn, smoother breathing, more control.

Again, even medical experts back it—Mount Sinai recommends nose breathing during exercise.

Now, I get it—on hills or sprints, nose-only might not cut it. That’s cool. I switch it up too:

  • Inhale deep through the nose when I can
  • Exhale through the mouth
  • Avoid shallow, rapid gasps

Here’s a pattern that works: breathe in for 3–4 steps, out for 3–4 steps. It slows things down and keeps you steady.

One Reddit runner said it made all the difference for their dry throat.

Also, don’t forget the basics—keep your mouth and throat from drying out in the first place.

Chewing gum helps produce saliva, which keeps things moist. I’ve done it on longer runs—just make sure you’re not chewing like a maniac while sprinting.

Small sips of water work too.

I usually start runs hydrated and keep a bottle nearby for longer efforts.

Even swishing water around your mouth helps sometimes.

2. Cold, Dry Air

If you’ve ever gone for a run on a freezing morning and felt like someone lit a match in your throat, yeah, I’ve been there.

Even though I live in Bali now, I still remember the shock of my first cold-weather run. I was visiting a friend in Europe, laced up at sunrise—5°C outside—and boom, throat burn within minutes. Not from effort. Not from pushing too hard. Just the air.

Cold air is dry air. And when you suck it in fast through your mouth, it strips the moisture from your throat like a sponge. There’s no magic shield—just raw, dry air scraping away your throat’s natural lining.

According to Runner’s World, this drying effect messes with your mucous membrane and triggers pain signals from the nerves in your throat.

That burning? It’s your body’s way of screaming, “Too dry! What the hell!”

Now toss in mouth breathing—common when you’re running hard—and it’s a perfect storm.

Your nose is designed to warm and moisten air before it hits your lungs.

But in the cold? We default to gulping through our mouths, especially on tempo runs or hills. And that icy air goes straight to your throat like a blade.

Doctors agree: when you skip nasal breathing in freezing weather, you’re letting dry air smack your throat’s protective lining. That irritation can cause coughing, a runny nose, even a sore chest after the run.

Your body starts working overtime to fix the damage—and you’re left wondering why you sound like you smoked a pack of menthols.

But here’s the deal: you don’t have to suffer.

I’ve worked with runners across Canada and Northern Europe—this comes up every single winter.

So here’s the playbook that works:

Cover Your Mouth and Nose

This is the go-to strategy.

A light scarf, buff, or neck gaiter over your face can change the game. It traps heat and moisture from your own breath, so the air you suck in is already warmed up a bit.

Doesn’t matter if it looks cool or not—it works.

One of my runners in Sweden swore by a simple bandana. Said it “worked like a charm.” That’s direct feedback from the trenches.

I usually go with a breathable gaiter—thin enough to breathe through, thick enough to take the edge off the cold.

Avoid bulky masks or anything waterproof that traps moisture. If it gets soggy, it’s useless. Go with gear made for running.

I start most cold runs with a buff over my mouth, then pull it down once I’m fully warmed up.

Breathe Through Your Nose (When You Can)

Your nose is your natural air filter and heater. It’s built for this.

When you run in freezing temps, try to breathe through your nose as long as possible. It humidifies the air, making it easier on your throat (Mount Sinai Health backs this up).

But let’s be real—pure nose breathing isn’t easy mid-run, especially when you’re trying to push.

So try this instead: start your run nose-only. Let your body ease in.

Do nasal breathing for the first 5–10 minutes, and even after that, try to inhale through your nose at least part of the time. Every bit helps.

I’ve trained myself to use a 3:2 breathing pattern early in cold runs (inhale for 3 steps, exhale for 2), and it saves my throat from that instant razor-blade feeling.

Warm Up Slower Than Usual

Don’t charge out the door like you’re late for a 5K start. Cold air needs to be eased into.

I tell every runner I coach: give your lungs, throat, and nose a chance to catch up.

Start with a 5–10 minute warm-up jog or even a brisk walk.

Your airways need time to open up, and your breathing needs to get into rhythm gradually.

Think of it like preheating your oven before baking—don’t just toss the pizza in cold.

Hydrate—Yes, Even in the Cold

I know, cold weather doesn’t feel like it’s dehydrating you, but it absolutely is.

Every breath you see puffing out like steam? That’s moisture leaving your body.

Science says that dry air pulls water vapor out with every breath. So if you’re breathing more, you’re drying out faster.

And a dry throat plus dry air = fire.

I sip water before my run, and on longer cold runs, I’ll even carry a soft flask and take small swigs just to keep my throat from turning into sandpaper.

It makes a noticeable difference.

3. Eating & Acid Reflux: When Your Stomach Sets Your Throat Ablaze

You’ve been there, right? You finish work, grab whatever’s closest—a granola bar, some leftover pizza—and head out for a run. Ten minutes in, boom: your throat’s on fire, and there’s that awful sour taste creeping up your mouth.

Maybe even a burp or two.

Yeah… that’s acid reflux messing with your run.

What’s Actually Happening In There?

When you run—especially if you’ve eaten recently—your body starts bouncing things around.

Literally.

That movement, combined with increased pressure in your belly, can push stomach acid back up into your throat.

You might not even get the usual heartburn pain. Sometimes it just shows up as a scratchy throat, constant throat clearing, or that hot, sour sensation mid-stride.

I love spicy food. I worship coffee. But mix those with a run right after lunch? Recipe for disaster.

A few weeks ago I had pizza—full sauce, extra cheese—and went running maybe an hour later.

Bad idea.

Two miles in, I wasn’t focused on my pace. I was just trying to stop my throat from melting. It wasn’t the air or my breathing—it was that damn tomato sauce making a comeback tour.

Time Your Meals Right

This one is simple, but powerful: don’t run right after eating.

If you had a full meal, give yourself 2–3 hours before lacing up. A small snack? Maybe 30–60 minutes, depending on what it is and how your body handles it.

Nowadays, I run early mornings. I’ll just nibble on half a banana or a couple of crackers, and save breakfast for later.

Made a massive difference. Lighter belly, clearer breathing, no throat flare-ups.

Know the Usual Suspects

If your throat burns regularly while running, take a look at what you’re eating before the workout.

Some foods practically beg to mess you up during a run:

  • Spicy stuff (hot sauce, chilies, spicy noodles)
  • Fatty or fried foods (think burgers, creamy pasta, greasy leftovers)
  • Acidic foods (citrus, tomatoes, vinegar-based anything)
  • Caffeine (yep, coffee can loosen the valve that’s supposed to keep acid in your stomach)
  • Carbonated drinks (all those bubbles = burps = reflux)
  • Chocolate & mint (surprisingly sneaky triggers)
  • Alcohol (double-whammy: reflux and dehydration)

Look, I’m not saying give up all your joys in life.

I still drink coffee—just not right before a run.

Watch Your Portions Too

Big meals sit longer in your gut—and that extra fullness can push acid up when you start moving.

If I’ve got an afternoon or evening run coming, I’ll go lighter on lunch and snack later—maybe a piece of toast or a handful of almonds. Just enough to take the edge off without weighing me down.

Also, not everyone does well running fasted, but running while stuffed is almost always a bad move.

Hydration Habits Matter

Another sneaky one: gulping too much water or sports drink right before a run. That sloshing feeling? It can trigger reflux too.

Instead, sip throughout the day so you’re hydrated without overloading your stomach right before heading out.

And if you find that sports drinks bother you—because they’re often acidic—try watering them down or sticking with water during the run and getting your electrolytes before or after.

Need a Little Help?

If you deal with acid reflux regularly (even outside of running), there are simple fixes. An over-the-counter antacid like Tums can take the edge off if you take it 20–30 minutes before your workout.

Some docs also recommend meds like omeprazole if your reflux is chronic, but talk to a professional before going that route. Mount Sinai suggests trying an OTC acid reducer an hour before exercise if diet and timing changes don’t cut it.

Personally, I avoid meds unless I’ve tried everything else—but for some runners, that little boost makes all the difference.

The Weight Factor (No One Likes Talking About)

Carrying extra weight can make reflux worse. More belly pressure = more acid pushing up.

If you’re on a fat-loss journey, just know that losing weight gradually can help reduce reflux long-term (OCMarathon).

There’s also something called LPR (laryngopharyngeal reflux)—basically silent reflux that mainly shows up as throat irritation. No heartburn, just burny throat, coughing, or hoarseness.

If that sounds like you, it might be time for a check-up.

4. Dehydration: A Dry Throat is a Burning Throat

Ever wrap up a run with your lips feeling crusty and your throat like it’s been sandblasted? Or roll out of bed, lace up, and already feel that dry tickle in your throat before you’ve even broken a sweat?

That’s dehydration kicking your butt.

Most folks overlook it. But think about it: when you run, you’re exhaling moisture with every breath (those foggy clouds in winter? That’s your water leaving).

Add in sweat—even if you don’t see it dripping—and your fluid loss adds up fast. If you haven’t been drinking enough, your throat dries out, and bam—you feel that burn.

Let me give it to you straight.

I once headed out for a late run here in Bali after a full day of coaching and zero water. About 20 minutes in, my throat felt like sandpaper, and every breath was a grind. I cut the run short, and I hate doing that.

Lesson learned. Even in humid weather, dehydration sneaks up. In drier climates or winter, it’s even worse because you often don’t feel thirsty.

Here’s how to stop it from ruining your run:

  • Drink steadily all day. Don’t just chug a glass before you head out. I tell my clients to aim for about half an ounce of water per pound of body weight daily. For someone at 160 pounds, that’s around 80 ounces or 2.3 liters. If your pee is pale and you’re not dry-mouthed, you’re on track.
  • Pre-hydrate. An hour or two before your run, sip on about 16 ounces (500 ml) of water. I usually down a tall glass first thing in the morning, especially if I’m running early. It gets everything primed.
  • Sip while running. If you’re running more than 30–45 minutes, bring water. A couple sips every 15–20 minutes is solid. On cooler days, you might be fine without it. But if it’s hot or you breathe heavy, you’ll feel the difference. I carry a small handheld bottle for longer runs—not a big deal, and it makes a huge difference.
  • Rehydrate post-run. Don’t forget to refuel your fluids after you’re done. Try to get in another 16 ounces or so within the hour. If your throat took a beating, warm water or herbal tea with honey helps. I like ginger tea with a touch of honey—tastes good and calms the scratchiness.
  • Electrolytes count. On long or hot runs, add electrolytes. But skip the overly acidic stuff if it irritates your throat. I go for capsules or low-acid mixes if I need them.
  • Cut the diuretics. Too much coffee or alcohol can dry you out. If you down a triple espresso and go straight into a tempo run, don’t be shocked if your throat feels like sand. Drink water alongside your caffeine.

Bottom line: hydration isn’t sexy advice, but it’s game-changing. Your throat needs moisture to handle heavy breathing. Forgetting to hydrate is like forgetting your shoes.

5. Train Your Breath, Protect Your Throat

Strong legs don’t mean much if your breathing sucks. When you learn to breathe better, you don’t just feel less throat burn—you run stronger, smoother, and calmer.

When I first started, I didn’t give breathing a second thought. I panted like a dog, gasped when it got tough, and didn’t know any better. But once I figured out how to take control of my breath, it changed everything.

Here’s how to make your breath your secret weapon:

  • Rhythmic Breathing: Sync your breath with your steps. A 2:2 pattern (inhale for 2 steps, exhale for 2) works well for easy runs. Some runners prefer 3:2 or 3:3 depending on pace. It takes practice but becomes automatic. I use it like a metronome—it calms me, keeps my heart rate steady, and stops me from gasping like a fish.
  • Belly Breathing: Breathe from your diaphragm, not your chest. Lay down, put a hand on your stomach, and breathe until your hand rises. That’s what you want to mimic when running. You’ll draw in more air, breathe less often, and avoid drying out your throat from rapid panting.
  • Relax Your Mouth and Throat: Tension tightens everything. I used to clench my jaw on hard runs—not smart. Keep your mouth soft and your jaw loose. Try touching your tongue to the roof of your mouth; it sounds weird but helps slow airflow and add a bit of moisture.
  • Use Nasal Aids: Can’t nose-breathe well? Try saline sprays or nasal strips. On allergy days, a saline rinse opens me right up. I’ve even slapped on a nasal strip during runs just to keep things flowing.
  • Train It Off the Run: Deep breathing exercises or yoga can increase your lung control. Even just 5 minutes of breathing drills a few times a week makes a difference. I added them before bed and noticed calmer runs after just a couple of weeks.

Take the time to work on your breathing. It doesn’t have to be perfect, and you don’t need to overthink it mid-race.
But for daily runs, especially easy ones, these techniques can save your throat and boost your whole game.

6. When a Sore Throat After Running Isn’t “Just Running”

Let’s get real—sometimes a throat burn after a tough run is no big deal.

But what if it lingers? What if it feels like something deeper?

Here’s how I break it down for the runners I coach—and for myself when I start second-guessing that raw feeling in my throat.

It Hurts Even When You’re Not Running

If your throat still stings or feels sore hours after your run—or even when you’re just chilling at home—it might not be “just” running.

We’re talking stuff like acid reflux (GERD or LPR), which can quietly inflame your throat over time. Or even something like mild tonsillitis that gets worse from all that heavy mouth-breathing on the run.

If there’s swelling, redness, or you’re running a fever, don’t just brush it off as part of the grind.
That’s your body waving a flag.

Running harder or longer than usual can sometimes weaken your immune system just enough to let a throat infection sneak in.

Sharp Pain or Trouble Swallowing or Breathing? Big Red Flag

Burning discomfort? Annoying, but common.

Pain that makes swallowing hard? Or breathing tough? That’s not normal.

I had an athlete once who struggled with a tight, burning throat that turned out to be vocal cord dysfunction—her cords weren’t opening right during hard breathing. Wild, right?

Another case? Severe allergies. One runner I knew always felt like her throat was on fire during spring runs. It wasn’t training—it was the pollen. She finally saw an allergist, got on antihistamines, and boom—problem solved.

Obvious Signs of Infection

If your throat feels like it’s burning and you’ve also got:

  • White spots or patches on your tonsils
  • Swollen lymph nodes
  • Fever
  • That classic “oh crap, I’m sick” feeling…

…then yeah, it’s probably more than just a hard tempo run. It might be strep throat or another infection—and running won’t help.

In fact, training through an active illness can knock you down harder and longer.

Here’s my own rule of thumb:

  • If it’s above the neck (slight sniffle, light sore throat), I might still jog easy.
  • If it’s below the neck—tight chest, fever, body aches—I don’t run. Period.

Here’s your guide to the above/below neck rule.

Blood or Weird Mucus? Pay Attention

Ever coughed up some pinkish mucus after a run? Freaky, I know.

Cold weather and intense effort can sometimes pop tiny blood vessels in your airway, and that’s where the blood comes from.
Still—it’s not something to ignore.

If you keep getting thick, funky mucus that burns your throat, it could be from postnasal drip (often caused by allergies or sinus problems).

You’ve Tried Everything… and It Still Burns

You’ve fixed your breathing, hydrated better, adjusted your pace, waited it out—and your throat still burns every time you run?

Time to bring in the pros.

An ENT or sports doc might run a scope down your throat (yes, it’s weird but helpful), or run some lung function tests.
They may spot exercise-induced asthma, acid reflux, or chronic allergies.

These are all treatable—sometimes with simple meds or small lifestyle changes.

Final Word: Breathe Easy, Run Strong

Running isn’t supposed to feel like you’re battling dragons.
That throat burn? It’s a bump in the road, not the end of it.

And the fact that you’re here, reading this, means you’re serious about making your runs smoother — and that’s huge.

You’ve now got a solid toolkit to work with. Let’s break it down:

  • Breathe smart: Slow down if you’re gasping. Inhale through your nose if you can.
    Mouth is fine when things get tough — just stay steady.
  • Hydrate like it matters: Pre-run, mid-run (if needed), and post-run.
    A dry throat is often just a thirsty throat.
  • Weather-proof your run: Use a buff or scarf in cold air.
    Chew gum or suck a lozenge if it’s dry out. Adjust your setup — you’re the boss now.
  • Fuel with intention: Skip heavy, acidic meals before runs.
    Give your stomach time to settle so acid doesn’t tag along mid-run.
  • Gear up: Nasal strips, lozenges, buffs, water bottles — these little things make a big difference.
    Try them, tweak them, find your magic combo.
  • Know when to call in help: If something feels off, get it checked.
    No shame in playing it safe.

And don’t forget — this isn’t just about avoiding a sore throat. It’s about learning to run with more awareness, more confidence, and more enjoyment.

Can Running Improve Your Immune System?

by

Ever notice how some runners just glide through cold and flu season without catching so much as a sniffle?

As a running coach, I see it all the time. Personally, I used to catch colds every couple of months – but then I took up running.

Now, I rarely get sick, and when I feel something “coming on,” I find that an easy run often helps nip it in the bud.

So, does running really boost your immune system? Short answer: yep.

Regular running (done right) can strengthen your immune defenses and help you avoid getting sick.

Science backs it up: moderate exercise primes your body to fight off infections, and active people generally report fewer illnesses than their sedentary counterparts.

But there’s more to the story.

Let me explain how running impacts your immunity, both short-term and long-term, plus the role of T-cells, the J-curve of overtraining, aging, and some everyday habits that’ll keep you healthy as a runner.

Short-Term vs. Long-Term Immune Benefits of Running

Right after you hit the pavement, your immune system goes into action.

When you run, your heart works overtime, and so do your immune cells. Research shows that even just 60 minutes of moderate running can temporarily boost the circulation of immune cells like neutrophils, NK cells, and T-cells.

Think of it like sending an internal squad of bodyguards on patrol. They race through your bloodstream, hunting down potential threats – viruses, bacteria – and neutralizing them quicker than they would at rest. This “heightened immune surveillance” can last for hours after your run, giving your body a short-term immune “high alert.”

It’s not just cell counts that get a boost – running causes other immune-friendly effects, too. For example, exercise raises your body temperature (kind of like a mini fever), which may help stop pathogens in their tracks.

Plus, it sparks temporary inflammation that strengthens your immune system by triggering anti-inflammatory cytokines.

Even one workout can make a difference: a study found that people who exercised for 90 minutes right after a flu or COVID vaccine produced more antibodies over the next four weeks than those who didn’t.

Imagine that – putting your training to work!

Now, let’s talk long-term benefits. Consistent, moderate exercise is linked to fewer sick days and stronger overall immunity. Studies show that active people have fewer upper respiratory infections (like the common cold) compared to their sedentary peers.

In my own experience, I’ve seen firsthand how a regular running routine can build a solid defense against illnesses. One runner I coach shared, “Since I started running, I can count on one hand the number of times I’ve been sick… I’m fitter than ever and my body is better at fighting things off.”

Sounds familiar, right? And it lines up with the science: regular running helps improve immune function and reduces chronic inflammation.

Don’t get me wrong. Running doesn’t make you invincible, but it does seem to teach your immune system to react faster and bounce back stronger. It’s like a “stress inoculation” for your immunity. A little challenge makes the system more efficient for next time.

But to fully understand why running works wonders for your immune system, let’s talk about one of the real MVPs – T-cells.

Running and T-Cell Function 

T-cells are like your immune system’s special forces. They hunt down virus-infected cells, coordinate attacks, and keep a memory of past invaders.

So, how does running impact these immune defenders? Turns out, running and T-cells have a pretty tight relationship, and it’s one that can make your immune response sharper.

When you hit the road for a run – especially at an easy-to-moderate pace – your body releases stress hormones like adrenaline. These hormones mobilize T-cells into your bloodstream.

And I’m not making this up.

One study followed runners during a three-hour run and found that their white blood cell count – including T-cells – spiked right after exercise. These cells hit the ground running, doing some serious surveillance.

Yes, their numbers dipped a bit later (we’ll talk about the “open window” soon), but they returned to normal within a day. The takeaway? Every run gives your T-cells a short-term boost in circulation, which helps with immune surveillance.

But running’s impact doesn’t stop there. Consistent exercise actually helps slow down the aging process of your T-cells, which means your immune system stays primed.

Studies have found that physically active people tend to have a higher proportion of “naïve” T-cells (fresh recruits ready to take on new threats) and fewer “senescent” T-cells (older, worn-out cells) compared to inactive folks.

Regular exercise essentially clears out the old cells and makes room for the new ones. This is huge for adaptability – your body is better at responding to new viruses.

One impressive study of older cyclists found that their thymus (the organ responsible for producing T-cells) was cranking out as many new T-cells as in young adults. That’s like giving your immune system a fountain of youth, all thanks to years of staying active.

Exercise also boosts regulatory T-cells (T-regs), which act like peacekeepers by preventing chronic inflammation. A 2024 Harvard study showed that the inflammation sparked by muscle use during exercise actually mobilizes T-regs to the muscles, where they help calm things down and promote recovery.

Essentially, running triggers a balance in your immune system – it’s inflammatory enough to defend and adapt, but also deploys T-cells to keep the peace.

So, every run doesn’t just improve your immunity; it helps keep your body’s inflammation in check, reducing your risk for diseases like diabetes and heart disease.

You might’ve noticed this balancing act in your own life. For me, running has become a way to manage stress. Unlike chronic mental stress – which can suppress immunity – the physical stress from running actually boosts immune activity.

The J-Curve: When Training Can Backfire

Let’s bust a myth real quick: more running doesn’t always mean better health. There is such a thing as too much of a good thing—especially when it comes to your immune system.

Back in the ’80s, scientists coined what’s now known as the “J-shaped curve” to explain how your infection risk changes with different levels of exercise.

Picture a J: at the left tip, sedentary people have average risk. Drop down the curve to moderate exercise? Risk goes down—you’re less likely to catch a cold.

Slide up the other side (aka training too hard, too often, with not enough rest)? Boom—your risk actually climbs higher than the couch potato’s. Crazy, right? But also very real.

So, What Actually Happens When You Overtrain?

When you hammer your body—especially with long or intense workouts and zero focus on rest, sleep, or food—you create a temporary immune dip.

Stress hormones like cortisol shoot up, while your white blood cell count (those little virus-fighting soldiers) can drop for hours afterward. This is what scientists call the “open window”—a 3 to 72-hour stretch post-run where your immune defenses are down and viruses can sneak in.

One study showed marathon runners were up to 6 times more likely to catch a cold after race day.

Sound familiar? You crush a race or a big week, then bam—you’re sick by the weekend. That’s your immune system waving the white flag.

And no, this isn’t just about running 100 miles a week. It’s also about under-recovery. If you’re skimping on calories, sleeping poorly, or juggling a stressful life, you’re stacking the deck against yourself—even if your weekly mileage isn’t that high.

How to Stay in the Sweet Spot

Here’s the good news: you can totally run a lot without wrecking your immune health. It all comes down to training smart, recovering hard, and listening to your body.

Recreational runners usually don’t hit the danger zone unless they’re going hard for over 90 minutes repeatedly without rest. Some newer studies even challenge the old idea of long-term immune suppression. Elite athletes—those who are well-adapted—actually seem to get sick less often than you’d expect.

But for most of us mortals, the golden rule still stands: Build gradually. Recover consistently. And when in doubt, back off.

How do you know you’re overdoing it? Watch for the red flags:

  • Frequent colds
  • Lingering fatigue
  • Slower recovery
  • Dips in performance

I coach runners to use these as signals. One of my athletes swears by the 80/20 rule—run easy 80% of the time, push hard just 20%. It’s a game-changer. It keeps your body in the low-risk zone while still building serious endurance.

Here are my best tips for protecting your immunity:

  • Take your rest days guilt-free. Recovery isn’t lazy—it’s smart.
  • Refuel right after big efforts. A mix of carbs and protein helps blunt cortisol spikes.
  • Avoid packed spaces right after hard runs. Your immune defenses are lower—don’t challenge them in a germ-filled gym or subway.
  • Prioritize sleep. Especially during peak training or taper weeks.

One thing I always remind my runners: rest is part of training. It’s not optional. It’s the glue that holds your progress together.

I used to beat myself up for missing workouts when I felt off. Not anymore. If anything, those rest days are what kept me going strong long-term. It takes guts to say, “I’m pulling back today.” But it’s often the smartest move.

Running, Immunity, and Aging 

You know what I love most about running? It doesn’t just help you live longer—it helps you live better.

One of the best things you can do for your aging immune system is stay active.

I’ve got a 70-year-old buddy who sometimes joins our morning runs out here in Bali. Guy’s a machine. He barely misses a session and hasn’t been sick in years. Always says, “Running keeps me young.” I believe him. And research backs him up.

Our immune systems weaken as we age—a process called immunosenescence. But studies show that lifelong runners have immune profiles more like someone in their 20s. Their thymus glands, which crank out infection-fighting T-cells, don’t shrink as much. That’s huge.

And it’s not just about T-cells. Running also helps reduce chronic inflammation, which tends to rise with age (what some call “inflammaging”). Older adults who exercise regularly also get a better, longer-lasting response from vaccines.

Run for Life, Not Just a Finish Line

Even if you’re starting later in life, it’s not too late to turn things around. I’ve coached retirees who told me they used to get sick constantly—until they picked up jogging. Now, they feel tougher, sharper, and more in control of their health.

My advice? Don’t chase intensity. Chase consistency. A 60-year-old who runs 4 times a week at an easy pace will likely have a stronger immune system than someone doing zero all year and then jumping into a bootcamp.

Yes, aging slows recovery. Yes, healing takes longer. But that’s all the more reason to keep running—and to keep doing it smart.
