Hello everybody: Did W8R1 yesterday and things going mostly great. But I am finding my knees are hurting with the longer runs. I know this is a comm n topic of conversation here and i guess I should do a gait analysis. I worry it is just age. My ankles haven’t been great either. I am also doing Pilates and swimming which I think will help too with time but would love any other tips. All the best to all the C25K gang!
