Grade: 2
Standard post-XC calf strain (although only one side, for once!). Hurts a bit in compression, e.g. if I squat down onto it.
Cause: XC race. As usual. Recovered by cycling (instead of running), stretching, self-massage. Usually takes 7-10 days so either wasn't trying hard enough in the XC race or the one-legged calf raises are helping.
