Should You Keep Running When Something Hurts?

Every runner has asked the same question at some point.

"Is this normal soreness, or am I actually injured?"

It can be surprisingly difficult to tell the difference.

Some discomfort is a normal part of training. Muscles become sore after challenging workouts, especially if you've increased your mileage or introduced new types of training. But not every ache should be ignored, and continuing to run through the wrong type of pain can turn a small problem into an injury that keeps you on the sidelines for weeks or even months.

As both a Doctor of Physical Therapy and a running coach, one of the most important parts of my job is helping runners understand when it's safe to continue training, when modifications are needed, and when it's time to temporarily step away from running so the body can heal properly.

Normal Soreness Isn't the Same as an Injury

Not every ache after a run is a reason to panic.

Delayed onset muscle soreness, often called DOMS, is completely normal after a hard workout, strength training session, or an increase in training volume. It's your body's natural response as muscles adapt to new demands.

In many cases, it's perfectly safe to continue running with normal soreness.

As a general guideline, if your soreness lasts less than 48 hours and your running mechanics haven't changed, it's usually appropriate to continue training. You may need to slow your pace or keep the run easy, but your body is often capable of continuing to adapt.

The key is paying attention to how you move.

When Pain Shouldn't Be Ignored

Pain is different from soreness.

One of the biggest warning signs I tell runners to watch for is a change in their running form.

If you're limping, changing your stride, or compensating because something hurts, your body is already telling you that continuing to run may be doing more harm than good.

Pain intensity also matters.

If your pain reaches about a 4 out of 10 or higher, especially if it's changing the way you run, it's often smarter to choose a different form of exercise temporarily. Cross-training activities like cycling, swimming, or using an elliptical can help maintain fitness while giving the irritated tissue time to recover.

Listening to those early warning signs can prevent a minor issue from becoming a much larger setback.

The Two Biggest Mistakes Runners Make

When pain first appears, I generally see runners make one of two mistakes.

Neither one leads to good outcomes.

Mistake #1: Stopping Everything

Some runners experience pain and immediately stop all activity.

They rest completely for several weeks.

Then, as soon as they feel better, they jump right back into their previous training schedule.

Unfortunately, the body usually isn't ready for that sudden return.

Without rebuilding strength and gradually increasing running volume, the same injury often comes right back.

Mistake #2: Ignoring the Pain

Other runners go in the opposite direction.

They convince themselves the pain isn't serious.

They keep running.

They continue increasing mileage.

They hope it will simply disappear.

Sometimes it does.

More often, it gets worse.

Ignoring pain doesn't make you mentally tougher.

It often means you're allowing a small problem to become a larger one that's much more difficult to treat.

Sometimes the Best Decision Is to Temporarily Stop Running

One of my runners experienced a fall during a training run.

After evaluating her symptoms, it was clear that continuing to run immediately wasn't the right decision.

She had swelling that needed time to settle down before her body could safely return to running.

Instead of telling her to simply wait until everything felt better, we developed a plan that allowed her to continue making progress.

During her recovery, I encouraged her to focus on Pilates, yoga, and mobility work while giving the injured area the time it needed to heal. Once the swelling had resolved and her movement improved, we gradually returned to running instead of jumping back into full training.

That gradual progression allowed her to recover safely while maintaining much of the fitness she'd already built.

Sometimes taking a short break from running is actually the fastest path back to running.

There Isn't Always a Simple Yes or No Answer

One of the biggest misconceptions about injuries is that runners either have to keep training exactly as planned or stop completely.

Most situations aren't that black and white.

Sometimes reducing mileage is enough.

Sometimes replacing speed work with easy running is the right choice.

Sometimes cross-training makes more sense for a week or two.

Sometimes complete rest is necessary.

The correct decision depends on the type of injury, how long symptoms have been present, how your body responds to activity, and what your overall goals are.

That's why individualized guidance can make such a significant difference.

The Goal Is to Keep You Running Long Term

As a physical therapist and running coach, my goal isn't simply to get runners through today's workout.

It's to help them continue running next month, next year, and for many years after that.

Sometimes that means modifying a training plan.

Sometimes it means reducing mileage.

Sometimes it means temporarily stepping away from running so you don't create a much bigger problem.

Making those decisions early often shortens recovery and prevents more significant injuries from developing.

Returning Too Quickly Is One of the Biggest Risks

Many runners become so eager to get back to training that they skip the gradual rebuilding process.

Feeling better doesn't necessarily mean your body is ready for full training.

Strength, mobility, and tissue tolerance all need time to recover, even after pain has improved.

Returning too aggressively often leads to recurring injuries that become increasingly frustrating over time.

When in Doubt, Ask Questions

One of the biggest advantages of working with a running coach who also understands injury management is that you don't have to make these decisions alone.

Instead of wondering whether your soreness is normal or guessing whether you should continue training, you have someone who can evaluate the situation, modify your plan when necessary, and help you make decisions that support your long-term goals.

That guidance often prevents weeks of unnecessary frustration.
