Went out today for this run confident I could make 25 minutes, however, 6 or 7 minutes in my right calf started to hurt again, I tried to run it off but it just got worse so just after half way I had to stop and walk home. Really disappointed at the moment, I think I'm going to have to leave it for a week and then try a gentle 5 mins to see if it's OK.
Any other suggestions?
