Are You Ready for Marathon Season? Here’s How to Stay Injury-Free

As marathon season kicks off, runners of all levels are hitting the pavements and trails with renewed motivation. But with the buzz of race day on the horizon, there’s also a noticeable rise in running-related injuries. Why? In many cases, it comes down to doing too much, too soon.

Running is an incredible form of cardiovascular exercise. It’s free, it’s accessible, and it does wonders for both body and mind. But it’s also a high-impact, repetitive activity that places significant mechanical stress on your muscles, tendons, joints, and bones. Without proper progression and recovery, even the most enthusiastic runners can find themselves sidelined.

The Body Needs Time to Adapt

The human body is brilliant at adapting to physical stress—but not all at once. Muscles can respond relatively quickly, often within a few weeks. Tendons, ligaments, and bones, however, take much longer—sometimes several months—and they’re not as vocal about when they’re under strain. This makes them particularly vulnerable to overuse injuries, especially when training intensifies too quickly.

That 10K you added to your weekly mileage? It might feel fine at the time, but deep down, your tendons and bones could be playing catch-up.

Overuse injuries such as shin splints, Achilles tendinopathy, stress fractures, and runner’s knee are common results of this imbalance. Tendons, for instance, strengthen in response to load but require consistent, gradual stress over time to adapt properly. Likewise, bones remodel in response to impact—yet that process can take anywhere from 12 to 16 weeks. When training ramps up faster than these tissues can recover, breakdown wins out over buildup.

So, What’s the Solution?

The good news is that most running injuries are preventable. The golden rule? Gradual progression. Most experts recommend increasing your mileage by no more than 10% per week (though this depends on your current baseline). It’s also important to:

  • Listen to your body

  • Include sufficient rest and recovery

  • Cross-train and incorporate strength work

  • Mix up intensity and speed

  • Focus on proper footwear and form
