Walk.
Run.
Walk again.

The return-to-running session: intervals, uphill drive and the downhill control where shin pain comes back.

Rest alone does not fix it

Rest settles the pain and lowers the capacity. The pain returns with the first week back unless strength went up in between.

Strength first, miles second

The calf has to be strong before the mileage goes back up. Reversing that order is the most common reason this returns.

Previous injury is the biggest risk

A history of shin pain is the strongest single predictor of the next episode. What is done between episodes decides it.

How to run it

  1. Springs before miles: the calf must store and return load before it runs on it.
  2. Quiet feet are the test. A loud landing is a landing the muscle did not absorb.
  3. Return to running on alternate days only, and add roughly ten per cent a week, not more.
  4. Any return of the old shin or calf pain during or the morning after: drop back one week and hold.
