Cumulative Overload: myTF’s model for tendon adaptation to running

A couple of months ago I released a new model to predict tendon adaptation to training. The feedback from runners has been overwhelmingly positive, so let’s dig into why tendons need their own overuse injury model, and how it’s implemented in myTF.

Running frequency chart

We recently added a new chart on the Trends page showing how many days per week you’ve been running, on a rolling 7-day basis. Sports science studies have shown that weekly run frequency is linked with injury risk, especially for those running only once or 6-7 days per week. The data suggests a balance between frequency and mileage is important for injury prevention.
