Running Myth 8 – Does Running Increase your Risk of Arthrosis?


Running increases risk of arthrosis of the knee because the repeated impact causes irreversible damage to the cartilage.


Several scientific studies have shown that arthrosis is no more common in runners than in non-runners.


On the contrary, runners tend to have thicker and stronger cartilage in their knees than sedentary people. If honouring the tissue’s ability to adapt, and not overstepping it, the cartilage will adapt to the increased mechanical stress and become more impact resistant.


Cartilage that has been traumatically injured has a limited potential to heal. Hence, there is a higher incidence of arthrosis in sports where traumatic knee injuries are more common.


Your body will adapt to the mechanical stress it is given. To safely do so it is important to stay within the tissue’s ability to adapt; no pain during or after running, and no morning stiffness.

  • Runners typically have thick and strong cartilage
  • Arthrosis after a traumatic knee injury is unrelated to running
  • Train within your optimal adaptation zone!
