Understanding Achilles Tendon Function

The Achilles tendon is one of the largest and strongest tendons in the body, responsible for supporting the foot during running. It can adapt to increased load with gradual training, but pain often occurs when there is too much stress on the tendon, typically due to excessive mileage, intensity, or hill running. Tendons take time to recover, so back-to-back run days should be approached cautiously. Proper load management and gradual progression are key to preventing Achilles injuries.
