How to Run Through Pain Without Wrecking Your Body
Every runner hits that moment: “Is this pain just part of the grind, or am I about to wreck something?” It’s a razor-thin line.
As someone who coaches runners daily here in Bali, I’ve seen folks tough it out when they should’ve rested — and others pull back too soon. So let’s cut through the noise.
In this guide, I’ll walk you through how to run smart when pain shows up. I’ll mix my own trial-by-fire experiences with rock-solid advice from physios and sports docs.
We’ll talk about soreness vs. injury, the “pain traffic light” rule, pre-run body checks, and a few mindset tricks that’ve kept me going when my body said stop.
My goal? Help you stay in the game — training harder, but not dumber.
Is It Just Soreness or a Real Injury?
That familiar ache after a tough run — is it your muscles saying, “nice work,” or a flare-up warning you to back off?
Let’s break it down.
If you feel sore 12–24 hours after a hard session, and it hangs around for a few days, that’s likely just DOMS — delayed onset muscle soreness. According to the American College of Sports Medicine, DOMS happens because of tiny tears in your muscle fibers.
It’s uncomfortable, but usually no big deal. You’ll feel tight, maybe a little achy, but you can still move pretty well and your strength holds up.
Dr. Scott Rand from Houston Methodist says if you’re “feeling tender and tight but still have normal range and strength,” it’s likely just post-workout soreness. Annoying? Sure. But not a reason to cancel your run.
Now, if the pain feels sharp, localized, or throws off your stride, that’s a different story. Red flag. Injury pain doesn’t just sit quietly — it often gets worse with movement or sticks around long after you’re done.
Dr. Rand notes that when pain starts limiting how you move or how strong you feel, it’s time to hit pause.
Here’s how I think about it:
- Soreness = background noise — it fades as you warm up.
- Injury = alarm bell — it usually gets louder, not quieter.
For example, I often start a run with tight calves. They usually loosen up by the third kilometer.
But I once ignored a weird knee twinge — ran through it — and ended up limping for a week.
DOMS lets you move okay (even if it hurts). Injury pain takes things away — like power, mobility, or control.
My Go-To Test:
Before you even hit the road, try this:
- Walk fast for 5–10 minutes. Still hurting?
- Jog in place or hop gently on each foot. Any sharp pain? Limping?
If pain spikes or throws off your form — that’s not DOMS. That’s your body throwing the brakes on.
🔑 Bottom Line: If the pain feels dull or tight but goes away with movement, you’re probably safe to run. But if it’s sharp, changes how you move, or hangs around with swelling or bruising — stop and deal with it.
The Pain Traffic Light Test
This simple trick has saved me more times than I can count — especially when I’m tempted to tough things out.
Green Light (Pain Level 0–3/10)
Mild soreness that stays the same or even improves as you run? That’s a green light. Keep going.
According to physiotherapist Matthew Boyd, anything in this range is usually safe. I’ve woken up with a 2/10 tightness plenty of times — and once I start running, it fades.
Yellow Light (Pain Level 4–6/10)
Now you’re in the “watch your step” zone.
If pain ramps up slightly during your run but chills out afterward — and doesn’t come back stronger the next day — you might be okay to keep going… carefully.
Drop the pace, shorten the run, or take walk breaks.
During one race, I felt a 5/10 twinge in my shin. I kept running — but slower, focused on form, and threw in some walk intervals. It never got worse. Had I pushed like usual, I’d probably be nursing shin splints now.
Red Light (Pain Level 7–10/10)
This one’s obvious: stop.
Intense, sharp, or worsening pain is a red light. Boyd says if you’re up in the 6–10 range, you’re stressing the system too much.
If something stabs or spikes when you run — that’s your body yelling STOP.
🟢 Want a cheat sheet? I made a printable Pain Traffic Light chart — tape it to your fridge or stick it by your shoes. Green = go, yellow = slow, red = stop.
My Pre-Run Pain Checklist
You don’t need a full medical degree to check yourself out. Here’s how I self-screen when something feels off.
Quick, dirty, and super effective:
15-Minute Walk Test
Brisk walk or easy jog. If pain shows up during the walk, that’s a yellow light.
I often do this barefoot on the sand here in Bali — gentle on the joints, good warm-up too.
Hop and Squat Test
Hop on one foot, then the other. Do a slow single-leg squat on each side.
If one side screams at you — take the day off. I had a day where my left knee winced every time I hopped. That was my sign to switch the run for mobility drills.
Range-of-Motion Check
Do some high knees, butt kicks, and leg swings.
Feel anything locked up or painful in your hips, knees, or ankles? That’s info you don’t want to ignore.
Mind Check
This one’s underrated.
I ask myself: Am I limping or shifting to protect something? If yes, I treat that like an injury, even if nothing hurts yet.
Compensations lead to breakdowns.
Old Injury Reminder
Got a history of ankle, hip, or IT band problems?
If that same area flares up, it’s not just “soreness.” It’s the body waving a red flag.
If most of these tests feel fine, I’ll run — but I still keep it light.
One yellow or red light? I pull back or swap the run for cross-training.
📱 Coach’s Tip: Make your own “Pre-Run Pain Checklist” in your phone notes. Run through it like tying your shoes. It’s quick, it’s smart, and it keeps you running long-term.
Pain You Can Run Through — But You’ve Gotta Be Smart About It
Let’s get one thing straight: not all pain means game over. Some discomfort is just part of the grind — the price of progress.
But you need to know the difference between the kind of pain you can manage… and the kind that sends you limping home.
Here’s the kind of stuff I’ve run through — safely — and how I handled it.
Muscle Soreness (DOMS)
You crushed a hard workout yesterday, and now your hamstrings or calves feel like they’ve been run over.
That 1–2 out of 10 soreness that loosens up as you move? Totally normal. I’ve had those stiff-calf days where the first 2K feels awful, but then they start to wake up.
When I take a rest day and come back the next morning, my calves always complain — but give ’em a slow warm-up and some light stretches, and they settle down. Just keep it easy. No hero pace.
Early IT Band or Shin Pain
Catch it early and keep it mellow.
If that tightness on the outside of your knee or your shin flares up but stays below a 4 out of 10 — and doesn’t get worse — you might be okay to keep going.
Physio Maryke Louw says that if your IT band pain comes on a few km into a run, never spikes above mild, and disappears within an hour after, you’re probably not in the danger zone.
I’ve had this happen. I was out on a 12K trail and felt that familiar ITB ache creep in around 3K. It hovered around 3/10, never got worse, and went away half an hour after I stopped.
I switched to a run-walk mix and got through it.
But let me be real: if that pain had jumped to 5 or started messing with my stride, I would’ve shut it down.
The Tendon “Warm-Up” Trick
This one’s tricky.
Some tendon pain — like early Achilles issues — can ease up as you move. Dr. Anh Bui (PT) explains that if it’s under 3/10, doesn’t get worse while running, and doesn’t blow up the next day, you might be okay to continue.
Personally, I’ve had a nagging Achilles tweak that mellowed out after 15 minutes. But I still played it safe — backed off the pace, foam rolled later, and started planning some rehab.
If the pain gets worse, or flares up the next day? That’s a no-go. Don’t roll the dice.
Compression, Tape & Surface Swaps
Sometimes you need backup.
I’ve had days where compression sleeves on my calves or quads made the difference between grinding through or heading home. There’s research showing compression helps reduce muscle fatigue and soreness — and I’ve felt it first-hand.
I also swear by KT tape. It’s not magic, but it gives me a bit of support and — honestly — confidence when something feels off. I’ve taped up my knee or Achilles and still finished the run strong.
And don’t forget the surface you’re on. If concrete’s too harsh, hit the treadmill or a trail. Lower impact = less pain.
On bad days, I use 30:30 run-walk intervals. It’s not about ego — it’s about keeping momentum without pushing past the edge.
Warm-Up Like You Mean It
If you skip your warm-up, you’re playing with fire. I’m serious.
On days when something feels off — a tight quad, a grumpy IT band — I spend extra time getting things moving.
I’ll throw in foam rolling (especially outer thigh), leg swings, walking lunges — even skipping drills. A solid 10-minute warm-up can take a 4/10 pain down to a 1/10.
So here’s the bottom line:
You can run through mild, stable pain — but only if you’re honest with yourself.
If you slow down, breathe, and the pain fades or stays tiny — you’re probably okay. Chalk it up to the usual running “aches.”
But the second that discomfort crosses the line — sharp pain, worsening mid-run, or post-run flare? Pull the plug.
How to Keep Training Without Wrecking Your Recovery
Just because something hurts doesn’t mean you need to throw your training out the window.
Sometimes it’s not about stopping—it’s about adjusting. I’ve been there: legs sore, ego bruised, worried I’d lose everything I’d built. But with a few smart moves, I stayed in the game.
Swap in Low-Impact Training
When your knees bark or your shins feel like they’re ready to snap, pounding the pavement isn’t the best idea. That’s where cross-training saves the day.
Try hopping on a spin bike, hitting the pool, or grinding it out on the elliptical.
If you’re really desperate (like I was during one injury block), strap on a buoy belt and water run in the deep end. Yeah, I once used a snorkel in the pool just to keep my form and breathing smooth — looked ridiculous, but it worked.
Heart rate stayed up, lungs stayed sharp, legs got worked — without any impact.
As Praxis PT puts it, low-impact training “maintains cardiovascular endurance while completely unloading the joints.” That’s gold when your body’s rebelling.
Run/Walk Splits
You don’t have to hit every run at full distance or intensity. Break it up.
One time when my knee was nagging, I stopped doing daily 10Ks. Instead, I started doing 5K easy runs in the morning and power walking another 5K later in the day.
My knee handled it better, and I still hit my volume targets without pushing too hard at once.
If you’re hurting, think small bites. Spread the effort out. Avoid giant jumps in weekly mileage — build gradually and listen to your body.
Crossover Days
This is where yoga, rowing, or strength training step in.
Yoga’s been my go-to on days when my joints feel tight. It loosens things up and keeps my core in check.
Strength training? Non-negotiable. Even when I can’t run, I’ll hammer a core circuit or do upper-body work.
If legs are out, I might hit seated resistance workouts, or get creative — like underwater kicks or single-leg drills.
The point is, don’t go inactive just because you’re hurt. Move smart.
Try the 3-2-1 Routine
Some coaches call this the “3-2-1 Rule.” It’s simple:
- Run three days
- Cross-train two
- Rest one
If something starts hurting? Trade a run day for more low-impact work or a full rest day. Don’t be afraid to adjust.
Soreness is one thing — lingering pain is a red flag.
Slow It Down to Keep Going
If you’re clinging to your mileage, then drop the pace. Ditch the sprints and go easy.
Easy running is recovery in disguise.
Instead of charging into intervals or tempo, mix in run/walks or jog a long hour with walk breaks.
What messes up most runners isn’t the distance — it’s the intensity.
My Go-To Injury-Smart Week Plan
Here’s a sample I’ve used when my body needed grace but my mind still wanted movement:
- Mon: Easy run or cycling + core
- Tue: Upper-body strength or swim
- Wed: Run/walk intervals
- Thu: Swim or yoga
- Fri: Easy jog (short)
- Sat: Gentle row or hike
- Sun: Rest day
Remember: some movement beats no movement. You’re not falling behind — you’re staying in striking distance. But play it safe. If any new pain shows up, back off.
Recovery: The Real Secret Sauce
Pushing through mild pain? Fine. But if you don’t recover right, you’re turning small soreness into a full-blown injury.
Recovery isn’t optional. It’s part of the work.
Ice & Contrast Therapy
Got DOMS or some inflammation after a brutal session? Cold works.
Try an ice bath — 10 to 15 minutes at around 50–59°F (that’s 10–15°C for my metric friends). Research from Mayo Clinic backs this up — cold immersion right after your run can help reduce soreness and swelling.
I only use it after the nasty sessions — otherwise, I’ve seen research hint that overdoing it might actually blunt long-term adaptation.
Compression Gear
Compression sleeves, tights, even boots if you have them — they help.
Sports Medicine Rockies also notes compression can lower muscle fatigue and perceived soreness.
Personally, I throw on calf sleeves during long runs and I swear my legs bounce back faster the next day.
Keep Moving (Gently)
The 24 hours after a tough effort are key. Don’t just lie there — go for a chill bike ride, a slow walk, or a casual swim.
Gentle movement helps flush out lactic acid and metabolic junk. I like a sunrise walk or a light yoga flow the morning after a hard session.
It’s not glamorous, but it resets the legs.
Foam Rolling: Hurts So Good
Grab a roller or massage ball and hit those tight spots. Even a few minutes helps.
Studies show foam rolling boosts range of motion and helps release tight tissue.
I’ll roll my calves, IT band, and quads for 30–60 seconds each, even multiple times a day if I’m stiff. It’s not comfy — but it works.
Fuel Up Right
Don’t skimp on your post-run fuel.
Within 30–60 minutes of finishing, grab something with carbs and protein. That 3:1 ratio (like chocolate milk or a banana protein shake) helps restock glycogen and kickstart muscle repair.
Hydration matters too — especially in Bali’s heat. I’ll chug coconut water or pop salt tabs to stay topped up.
According to Sports Medicine Rockies, the key is: “eat a balanced meal or shake with carbs and protein within 30–60 minutes post-workout” and “rehydrate with water or an electrolyte beverage.” Simple but powerful.
Sleep Like You Mean It
This is your real recovery weapon. Most of your muscle repair happens during deep sleep.
Aim for 7–9 hours. Sports Medicine Rockies highlights that growth hormone — aka the body’s repair crew — kicks in while you’re asleep.
One bad night? You’ll feel it. A week of it? That’s when injuries sneak in.
Track What Hurts
I keep a basic training journal — either on my phone or an old notebook.
I log how I felt, what workout I did, what shoes I wore. It’s how I learned that concrete + dead trail shoes = calf hell.
You’ll spot patterns fast once you start looking. Every flare-up is a message — don’t ignore it.
The Mental Game: How I Stay Sharp When My Body’s Falling Apart
Let’s be real — pain doesn’t just mess with your legs. It sneaks into your head too.
And that mental battle? It’s often tougher than the physical one.
Over the years, I’ve learned a few ways to keep my head in check when things go sideways on a run.
Here’s how I talk myself through it.
Don’t Deny It — Work With It
First off, I’ve stopped pretending pain isn’t there. That just leads to worse decisions.
Instead, I follow what Coach Danielle Hirt says: “Acceptance isn’t giving up — it’s stepping into reality.” That mindset alone has saved me from spiraling.
If my Achilles starts barking mid-run, I don’t panic. I tell myself, “Alright, this is here — what can I do about it?”
That calm shift from denial to strategy keeps me smart and safe.

Talk to Yourself — Literally
I know it sounds strange, but I actually talk to myself out loud when I’m struggling.
“You’ve pushed through worse,” I’ll mutter. “One more step.”
Research backs this up — turns out, athletes who speak to themselves using “you” instead of “I” perform better because it helps create distance from the pain and improves focus.
When my legs feel like concrete, I don’t tell myself, “I’m tired.” I say, “You’ve got this. Keep going.” That switch in wording works like magic — especially when I’m on the edge.
Mental Replays: Visualize the Win
After a rough day, I’ll lie in bed and picture myself running smoothly again. The brain’s wild like that — it starts to believe what it sees.
Coach Hirt swears by it, and so do I. I imagine my form locked in, gliding over my favorite trail, pain-free.
Is it a bit woo-woo? Maybe. But it shifts me from frustration into hope.
That’s worth something.
Don’t Go It Alone
Pain has a way of making you feel isolated.
I’ve had those moments — scrolling Strava, feeling like everyone else is flying while I’m grounded. That’s when I reach out.
I text a running buddy, post something honest online, or even join a group chat. Someone always replies, “Yep, been there.” And just like that, I’m not alone anymore.
If your gym or local run club has an injury group, join it. Even if you’re limping, you still belong.
Ride the Waves, Then Reset
Let me tell you — some days just suck. And that’s okay.
I give myself 15 minutes to sulk if I need to. Then it’s back to work. I’ll stretch, roll, or just clean my shoes — anything to move forward.
Coach Hirt said it best: “Be frustrated briefly. Then refocus on what you can do.” That’s helped me reframe injuries as pit stops, not full stops.
Coach’s Note: Setbacks are part of the sport. Pain is guaranteed. But how you respond? That’s where growth lives.
For me, even hobbling back from a failed run still counts — because I’m learning something.
Now you: How do you stay mentally strong when things hurt? Got a mantra that gets you through? Drop it below — I’d love to hear it.
When It’s Time to Call in the Experts (And What to Ask)
You can be tough — but don’t be foolish.
Some pain doesn’t go away with foam rolling and positive thinking. Here’s when I get outside help — and how I make it count.
Red Flags That Say “See a Pro”
If something’s still hurting after a few days off — or you’re limping through life, not just your runs — it’s time to get checked.
NHS guidelines say any pain that sticks around into daily activities (stairs, walking) needs attention.
And PT Matthew Boyd says this clearly: if you’re limping or waking up at night in pain, don’t wait — book an appointment.
Been there. I once waited two weeks with a sore knee before finally getting help. Turned out it was a strain that could’ve healed faster if I’d stopped being stubborn.
Make Sure They “Get” Runners
Not all doctors speak our language. Some will just say “stop running” and call it a day. That doesn’t cut it.
You want someone who understands runners — ideally a sports PT or someone with endurance training background. They’ll focus on getting you back out there, not locking you in a boot unless it’s absolutely needed.
Ask this straight up: “Can I run through this while rehabbing, or do I need to stop completely?” It helps filter fluff from facts.
A good PT won’t just toss ibuprofen at you — they’ll give you real drills, like glute bridges, ankle strengtheners, or a modified plan.
Boyd even mentions that most runners don’t need more than a week completely off.
Ask the Right Stuff
Here’s what I always ask during a PT visit:
- “Worst case — what could this be?” (Is it a muscle strain or a stress fracture?)
- “Can I keep running if I dial it back?”
- “What specific exercises will fix this?”
- “How do I stop this from happening again?”
These questions get you real answers, not vague advice.
Learn from the Pros
I’ve picked up gold nuggets in PT sessions.
One therapist showed me that my recurring hip pain wasn’t the hip — it was my glutes slacking off. That one insight changed how I train.
Now I throw in band walks, single-leg bridges, and the problem’s been gone for months.
Final Takeaway: There’s no shame in asking for help.
Seeing a PT isn’t admitting defeat — it’s training smarter. It’s buying future miles.
FAQs – Real Answers to Common Running Pain Questions
Q: Should I run through knee pain?
A: Most of the time, that’s a hard no.
The UK’s NHS doesn’t sugarcoat it: “Do not run if you have pain in your knee.”
If it’s a minor ache and goes away after a few days off, cool — you’re probably okay. But if it lingers or swells up? Shut it down and get it checked.
I’ve seen too many runners try to “run it off” and end up limping for weeks.
Bottom line: if it’s dull and fading, rest, ice, and monitor. If it’s sharp, swelling, or messes with your walk — call in the pros.
Q: What’s the difference between normal soreness and an injury?
A: Soreness — like that post-leg-day stiffness — feels achy and tight but eases up once you move around.
That’s DOMS (Delayed Onset Muscle Soreness). You can still move well, and it fades within a few days.
Injury pain is a different beast. It’s sharp, lingers at rest, and often messes with your stride.
If it hurts to walk, or you lose strength or range of motion — that’s not just soreness. That’s your body waving a red flag. Pay attention.
Q: Can I run with a tendon strain (like Achilles or patellar tendonitis)?
A: You might be able to, but only with caution — and a game plan.
Here’s what I tell my athletes: If your tendon pain is under a 3 out of 10, doesn’t spike during your run, and feels no worse the next day, you’re probably okay to keep going — but easy does it.
That means flat surfaces, slow pace, and chopping your weekly mileage in half.
But if it crosses that 3/10 pain line, hurts more while running, or leaves you stiffer the next morning — it’s time to back off.
Switch to rehab drills or cross-training. Don’t push tendons past their limit.
Trust me, I’ve done that, and it backfired hard.
Q: How many days of pain is too many?
A: Trust your gut. But as a rule?
If something still hurts after 3–7 days — even after dialing things back — it’s time to take it seriously.
If that knee’s still cranky after a week off, or your Achilles is sore two weeks later, that’s not normal.
NHS says to stop and see a specialist if pain hangs around or creeps into your daily life.
[nhs.uk]
Short breaks now beat forced time off later.
If you’re second-guessing whether to run — don’t. Play the long game.
Q: How do I push through running discomfort safely?
A: First, know the difference between discomfort and danger.
Mild, steady soreness? You can work with that. But you’ve got to be smart.
- Dial back your pace
- Mix in walking
- Choose softer ground
- Use tools — taping, compression sleeves, whatever helps
[sportsmedrockies.com]
[runresilientlydpt.com]
I always warm up longer when something feels off.
If the discomfort stays low and doesn’t flare up afterward, you can probably keep going.
But if it spikes mid-run or shows up stronger the next morning, that’s your cue to stop.
You’re not “toughing it out” — you’re managing risk. There’s a difference.
Final Word from Coach Dack
Pain on the run can rattle your confidence — but if you learn to read your body like a coach would, you’ll bounce back stronger.
Don’t sacrifice long-term consistency for one “hero run.” Know when to push, when to pause, and when to seek help.
Your future miles are built on today’s smart choices.
