Just found out i'm gonna be off the bike for about 4 months. I've torn the medial ligament and some of the cartilage in my knee. Already been out of action for about 3 weeks and I'm going mad. Any suggestions as to how to pass the time without being able to go biking and how not to loose what fitness I have when I've been told no sports for 4 months after my opp which isn't happening till the end of the month. What makes it worse is my new bike is due to arrive tomorrow.
