I have been running for about three months and have really tight calves. Sometimes I have to stop repeatedly during a run to stretch them. I run about 30-40 mins, 3 times a week.
A search of the internet suggests that I have "posterior compartment syndrome" - a muscle growing too big for its sheath - which is apparently not uncommon for beginners.
But what do I do about it? I imagine that frequent massage is a good idea. And maybe exercising the other calf muscles (with standing calf raises) will help balance things out? I've recently also gotten some proper running shoes (I did have too-small crosstrainers), so that may help.
Is there anything else I can do to rid myself of this?
