So I have never been a runner - always pants at it from school. Began this programme and felt vey upbeat that I was giving it go. Ran wk 4 run 2 and have now got awful pain in one calf. Have rested it for 5 days now and after seeming to get better is worse again. If I can only get to week 4 before injuring myself what are the chances of me completing this? Reinforces all my fears that running is beyond me.
