Ok just completed W2R1in the local park. Completed my warm-upend started to run, felt great, not breathless, slow and steady then on the second run the calf pain set in again! Calves felt really tight so stopped briefly to stretch but they gradually got worse with each run. I managed to finish through gritted teeth but besides lots of stretching I'm not sure what else to do? I'm thinking of taking an Ibuprofen before my run. I know it's early days but please tell me it gets better with time!
