I'm on a rest day but have recently completed week 5. I have very sore knees for the first time in the last 5 weeks. Meant to be starting week 6 tomorrow but I don't know if my knees are ready for it. Ironically they are more painful on resting than once I am up and moving about. Any tips to help or prevent this getting any worse. I am wearing running shoes that were fitted at a specialist retailer who examined my gait and running technique.
