This is my first post on here but i've been lurking for the past 9 weeks! Ive just started week 9 of the couch to 5k plan and am really enjoying it. Ive never run before in my life and wish id done it sooner. This week I seem to have developed sore knees though It doesnt happen when i run and is mainly a problem the day after a run so im not sure if its connected or not. I first noticed it on wednesday when i was out for a long walk with my dog. Its mainly around my knee caps and I can feel them grating . Last night one of them woke me up because it was so stiff and sore but by the morning it was fine. Ive been out for a run today and am pain free at the moment. Can anyone shed any light on this? I really dont want to stop running because I love it.
