Sharp, sudden, or one-sided pain means stop and walk it out — that's your body sending a clear signal. Dull, general soreness that eases up once you're a few minutes into the run is normal training feedback, not a red flag. Once you know which bucket you're in, the "should I stop?" question gets a lot easier to answer.
Beginners hear this advice constantly — in fact, it was the second most-upvoted tip in a recent r/BeginnerRunning thread asking what advice actually made a difference, right behind "just get out the door." The reason it lands so well is that pain-versus-discomfort isn't obvious when you're new to running and every sensation is unfamiliar. Here's how to tell them apart.
What's the difference between discomfort and pain?
Discomfort is the general, everywhere feeling of effort: heavy legs, quicker breathing, a mild ache across both calves or thighs. It usually shows up gradually, affects both sides of your body evenly, and eases as you warm up or ease your pace. That's your fitness building — a good sign, not a warning.
Pain is different. It tends to be:
- Sharp or stabbing rather than a dull ache
- Localized to one specific spot — one knee, one ankle, one side of the shin
- One-sided, showing up on just one leg or foot while the other feels fine
- Getting worse as you keep running, instead of fading
- Still there, or worse, once you've stopped and rested a few minutes
If what you're feeling matches any of those, that's the moment to stop, walk, and reassess — not to push through for one more kilometer.
What should you actually do when it happens?
Walk for a minute or two and see how it feels. If it fades with lighter movement, you can often finish an easy walk-run home. If it doesn't fade, or it gets sharper, stop your run there, head home, and give it a day or two of rest before trying again — light stretching and rest usually take care of everyday tightness. If pain comes back the moment you start running again, or shows up at rest too, that's worth mentioning to a doctor or physio rather than guessing.
Is it ok to run through general soreness?
Yes — general muscle soreness, especially the kind that shows up a day after a longer or harder run (often called DOMS), is completely normal and easy runs actually help it fade. The rule of thumb: soreness that improves as you move is fine to run on; pain that worsens as you move is not.

How do you build the habit of listening to your body?
New runners often push through pain because they don't trust themselves to know the difference yet — but that instinct gets sharper fast with a little practice. A few habits help:
- Check in every few minutes on a run: is this soreness or is this pain?
- Note where it is. One joint, one side, or a specific spot deserves more caution than an all-over ache.
- Don't chase a number. A great run isn't one where you gutted out pain to finish; it's one where you finished feeling good and want to go again tomorrow.
- Rest days count as training. Recovery is where your body actually adapts — see our running recovery tips for beginners for what to do on those days.
That last point matters more than it sounds. The goal of running, especially early on, is to build a habit you keep for years — and you can't do that if you're sidelined by an injury you ran through instead of around.
FAQ
Is it normal for my legs to hurt after every run when I'm just starting out? Some general muscle soreness in the first weeks is normal as your body adapts — it should ease within a couple of days and lessen as you build a base. Sharp or one-sided pain that doesn't ease is different and worth stopping for.
Should I run through shin pain if it goes away after a few minutes? Be cautious with shin pain specifically — it's one of the more common overuse injuries in new runners. If it fades quickly and stays mild, an easy pace is usually fine, but recurring shin pain deserves a closer look and a lighter week.
Does needing to walk during a run mean something is wrong? No — walking is a normal, smart part of the run/walk method most beginners use, and it's completely different from stopping because of pain. Walking by choice builds endurance; stopping because of pain protects you from injury. Both are good decisions, just for different reasons.
Learning to tell discomfort from pain is one of the most useful skills a beginner runner can build — it's what keeps you running for years instead of sidelined for weeks. Pair that instinct with gear that keeps the rest of your run simple, like a snug phone armband that stays put so you're not fiddling with your setup mid-run.
Run happy, run free.
