I'm running week 7 run 3. Had no injuries up until today. Warmed up as normal, stretched etc and then ten minutes in my right calf sent out an awful pain. I had to stop and hobble home. Oh no, how long should I wait until I run again. Am very down about this as I have worked hard to achieve what I have done so far. Feeling miserable ....! Fearing that I will have to wait and then I won't be able to do the 25 mins again which was hard !
