2 Ways to Stop Achilles Tendon Soreness While Running

The 2 key strategies to prevent Achilles tendon soreness while running is to 1. Avoid heel strike and 2. avoid running with an upright trunk.

Leaning forward and landing on your forefoot are the 2 key ways to prevent Achilles tendon soreness.

1. Land Forefoot, Not Rearfoot

The stride parameters of forefoot running effects force distribution on the Achilles tendon in ways the may reduce Achilles tendon soreness. For example, forefoot running reduces over-pronation because ground contact time is much shorter as compared with heel strike running. As a result, harmful impulsive forces are less likely to accumulate during stance in forefoot running.

In many cases, Achilles tendon soreness is mainly the result of inappropriate foot movements during mid-stance whereby heel strike running tends to prolong mid-stance because ground contact time is extended. Moreover, Lake et al. (2008) found that heel strike runners had high amounts of Achilles tendon stress concentrated above the calcaneal insertion. This finding jibes with earlier reports that found 80% of Achilles tendon ruptures occurred in this area (Aroen et al. 2004).

2. Stop Running Upright and Lean Forward More

Typically, most runners who heel strike run with an upright body posture which causes the center of mass to stay behind initial foot strike position. This not only increases mechanical work on the legs –the legs work harder to pull the center of mass along during running, but it increases braking as well. This could reflect a consequence of Achilles tendon soreness that persists.

Lorimer and Hume (2014) believes that directing the center of mass further forward reduces braking and may lower the occurrence of Achilles tendon soreness during running.

The Take Home Message

Even though running increases peak stress on the Achilles tendon, the mechanical parameters of heel strike running appears to add extra stress on the Achilles, which causes peak stress to markedly increase beyond a tolerable limit. Because forefoot running involves less mechanical work and safer foot-ground interactions, suggests that forefoot running may improve biomaterial fatigue performance of the Achilles.

"I believe the forefoot strike is the engine of endurance running..."

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
