Just getting over Keepfit on Wednesday and today my knees are the worst they've ever been. Prob not bad as knees go but I'm going to make a real effort to re-read and do the exercises that CaroleC told me about. Better to do it now than let it get any worse. I'm trying to change the way I run because I probably put the whole of my foot down at the same time which may not help. Not only can I not breathe, now I can't run either!!!!
