I am looking to rejoin TA, im 29 now. Ive started running again (use to be quiet good) but my knee is playing up, its a problem that started 8 years ago during my recruit course and its back. Tried knee support, but didn't seem to help. Normally starts after first mile, i'm fine and generally fit, fear i would not hack two weeks with it as it is. Also, why does it start in the first place, was it all that running in my boots, i lived out of them for days on end???
