I woke in the middle of the night with cramp in my calf muscles. This isn't all that unusual and seems to have as much to do with genes as running as my mother suffers from leg cramps and I don't think she has ever run 10km, and certainly not in the last 30 years. This time the pain was a little higher than usual and the muscles were reluctant to relax. I had to get the roller on them for 10 minutes before I dared do much stretching.
During the day I've used the roller and stretched a few times and now it's only mildly irritating. Hamstring and behind the knee seems OK. All the same chain of muscles though. I'm wondering if it has anything to do with wearing my more worn (>500km) shoes. I don't know, but it's logged here now.
I'd best go and do more rolling.
