I have just completed W7R1 and although I have to push myself I am beginning to feel that I can really do this. However, at the start of every run my knees twinge (in fact they twinge in the warm up walk!) After 5 mins or so of running the pain recedes into the background a bit, but I really feel it towards the end of the run and my warm down walk is painful. The pain lasts for a day or two, especially going up or down stairs. I am taking 2 or 3 days rest in between each run to make sure my knees feel O.K. I have also splashed out on v.expensive pair of trainers after having my gait analysed, but they have not made a difference. Just wondering if there is anything else I can do...I would really, really like to get to week 9!
