In reply to thelostjockey:
Had a number of problems with calves over the last year or so. It stopped me running for about 3 months. I did a lot of "power" walking leading up to starting running again which helped as I could gauge when it was hurting. Run/walk strategy followed now back to full running - but key thing for me is that I deliberately run slower than before and it seems to have helped.
Gave up with stretches, rollers etc as it didn't seem to help
Sorry I also saw physio for a few months prior to getting going again.
