Why Runners Get Injured — And What You Can Do About It

Expert advice from Memphis physical therapists who specialize in helping runners stay healthy for life

Running is one of the oldest sports in the world, and it's more popular than ever. Whether you’re training for the St. Jude Marathon, logging miles on the Memphis Greenline, or traveling with your shoes in your carry-on, running is one of the most convenient and empowering ways to stay fit.

It’s simple: just lace up and go. Tight on time? Running is efficient. Out of town? It’s the perfect way to explore a new area and pack light.

And the benefits are impressive — studies show that regular runners live, on average, 3 years longer, and reduce their risk of premature death by up to 40%.


That’s worth pushing for, right?

But if running is so good for you, why do so many runners get injured?

The Truth About Running Injuries

Research shows that up to 90% of runners experience an injury or illness during training for a half or full marathon.
That doesn’t mean running is bad for you. But it does mean that running, like all repetitive, high-load sports, carries risk.

The most common issues we see at 901PT in Memphis are overuse and stress injuries caused by increasing training volume or intensity without enough time for the body to adapt.

These injuries can be influenced by:

  • Biomechanics and movement patterns
  • Training volume, frequency, and intensity
  • Past athletic history and strength base
  • Sleep, stress, nutrition, and hydration
  • Footwear, running surface, and even weather

In other words, running is simple, but the human body is complex.

Can We Prevent Running Injuries 100%?

Maybe not. But we can reduce the risk significantly.


That’s where physical therapy for runners makes a huge difference.

Reducing injury risk means:

  • Understanding how the body absorbs and adapts to stress
  • Addressing weak links before they become injuries
  • Progressing training load in a strategic and balanced way

At 901PT, we help runners in Memphis do exactly that through detailed assessment, smart training guidance, and personalized treatment plans.

Your Body Is Built to Run — Here’s How It Handles the Stress

The human body is made to run. But that doesn’t mean it doesn’t need support. Let’s look at three key systems that support your performance and resilience:

1. Bones: Your Shock Absorbers

Bones form the framework of your body and help absorb impact while providing attachment points for muscles and tendons.
Bone tissue is constantly remodeling, breaking down and rebuilding, and this process is influenced by your age, hormones, diet, sleep, training, and whether you played sports as a kid.

For runners, bone stress injuries like stress reactions or stress fractures are a common issue when load exceeds bone recovery capacity.

2. Tendons: Your Springs

Tendons connect muscle to bone and store elastic energy during impact, like springs that help you bounce off the ground.

Tendinopathy is a common running injury, but contrary to popular belief, stretching isn’t the answer. In fact, stretching can sometimes make tendon issues worse.


What tendons need is strategic loading and strengthening, not just rest.

3. Muscles: Your Engines

Your muscles generate the power to propel you forward and control your landings. Each muscle group behaves differently depending on the pace and phase of your running stride.

Weakness in key areas like the calves, glutes, or hamstrings can reduce efficiency and increase injury risk.
Building tissue capacity and improving neuromuscular control are essential for both performance and injury prevention.

Fatigue Doesn’t Just Happen in the Legs

In endurance sports like running, the brain and cardiovascular system play just as important a role as the muscles.

Fatigue isn’t just physical, t’s neurological, emotional, and perceptual.

Historically, scientists debated whether fatigue comes from the heart (not pumping enough) or the brain (protecting the body from overexertion). The most modern theories now say: it’s both.

Stress, sleep, motivation, competition, and mood all influence how your body performs and how likely you are to get injured.

That’s why we don’t just treat the site of pain at 901PT. We look at the whole system to identify what’s contributing to fatigue, breakdown, or poor recovery.

Balancing Load: The Real Secret to Staying Healthy

Here’s the hard truth: most running injuries happen when people do too much, too soon or return to training too quickly after a break.

To improve as an athlete, you need to gradually exceed your current capacity. That’s how the body gets stronger.
But if you go too far too fast, tissues can’t keep up and something breaks down.

The old “increase mileage by 10% per week” rule is a helpful guideline, but not a universal law. Some runners can handle more, others need a slower ramp-up. Your history, age, recovery habits, and current fitness all play a role in how quickly you can progress.

What matters most is avoiding:

  • Sharp spikes in training volume or intensity
  • Sudden drop-offs, like when you stop running completely and then jump back in
  • Inconsistency, which makes it harder for your body to adapt

So… Is It Worth It?

Yes. Absolutely. Running is one of the most powerful things you can do for your body and brain.

And even if you do get injured, most running injuries heal well, especially with expert guidance and a long-term plan.
