Am on week 7 run 1 and 5 mins before the end of the session as I was runnign I got the sensation that my knee needed to "click", I kept jogging but each time i put my knee down it did it again and again. I took my headphones out and I could actually hear it "click" as i put my foot down/pushed off. Although i had no pain i decided it best i stop jogging and did a brisk walk home. Waling is fine, it doesn't ache. Ideas on what it could be, etc are greatly welcomed. But I am more interested in those of you who have had similar to see if some support my be useful next time? My knees do click a bit normally esp if I walk up the stairs.
