I have been having a problem with my calf for about the last 3 weeks, After about 30 mins on fells it starts to feel like it is really tight but i dont feel no pain are pulling but i can run on the road for about 50 mins before i feel anything and the weird thing is that i only feel it in training and it does not affect me in races, I have been warming up and stretching and cooling down so i dont think it is that which i thought it could of been
Has anybody got any ideas are suggestions how to get rid of it??
