Hi all - newbie to here (and to running). This morning I started week 4 of the plan - never, ever thought i'd be able to run for 5 mins without stopping but I managed it and feel so good for it. However when I'm running, I've noticed that my left knee feels like it's jusy going to 'go' sometimes - I get kind of a quick sharp pain and it feels like it's going to give way under me but then it goes away. I'm really enjoying this programme so would hate to pick up and injury - i've noticed it since week one so don't think it's just because the distances are increasing. Is it worth considering something like a knee support whilst running?
