Today is a sad day because I realised im going to have to say goodbye to running for a little while. I've been following a B210k plan & a couple of weeks ago while out on my first 9k run I developed a pain in the outside of my knee. After a bit of googeling it seemed like I might have something called IT Band (friction) Syndrome. I left it a couple of days, and then a whole week before attempting another (4.5k) run but both times its resulted in more knee pain (as well as what feels like a bit of groin strain today). I'm super sad about this because I had gotten so close to 10k and it was the first time I'd been able to do such distances. I've completed, and stopped C25K before and then always had to go back to the start when taking it up again. I really want to avoid this so I was wondering if anyone had any experience with ITBS? How long did you take off from running and what (if any) exercise did you do during your time on the injury couch to keep fit?
