Soreness or Injury? How to Tell the Difference During Marathon Training

One of the biggest questions marathon runners ask is whether they're dealing with normal soreness or the beginning of a true injury. The answer isn't always obvious. As training volume increases, muscle soreness is expected—but pain that changes how you move should never be ignored.

Delayed onset muscle soreness (DOMS) usually develops 24 to 48 hours after a challenging workout and gradually improves over the next few days. It typically affects both sides of the body equally and feels like generalized muscle stiffness. Injuries, on the other hand, are often more localized. Sharp pain, swelling, pain that worsens while running, or discomfort that changes your running mechanics are signs that warrant closer attention.

Ignoring these warning signs can lead to longer recovery times and missed training opportunities. Addressing minor issues early often means less downtime and a faster return to running. Monitoring your symptoms, modifying your workouts when needed, and seeking professional guidance can help prevent small problems from becoming season-ending injuries.
