I have a charity 10k run on the 4th June, Roughly 4 weeks away. Recently every time i run my shins and calves get extremely tight so i took a few days off. I decided my legs felt better yesterday so went for a short run and again straight away my legs started playing up again and just below my knee caps started to hurt. I thought it would be best to take a bit of time off running to recover. I am now slightly worried that i won't be able to finish the 10k for charity without my legs causing issues. Is it possible i could still do the 10k race or would it be best to give it a miss? I would be disappointed if i couldn't do it so i'm willing to try anything that could help.
