I wrote a post yesterday but it seems to have evaporated, so I am trying again.
After a break of almost two weeks in a very warm location (good) with no opportunity for exercise (bad), last Friday I started to get back to where I was with a quite brief run of about 2k, prefaced by the required brisk walk. The outcome was sore knees, sore calves, and a sharp pain in my right thigh, especially when the leg was bent slightly. There has been a slight improvement since then, particularly during gentle exercise, but not enough for me to contemplate the parkrun this Saturday, which was my aim. The thigh pain still catches me out occasionally.
I thought I was approaching running after a rest in a sensible way but the outcome indicates that I wasn't. Where did I go wrong?
