Finally got back out on my bike today but somehow stupidly set strava up for a run! I decided to take it easy on my right knee. I don't seem to have lost any progress in my fitness considering i've been off the bike for a 2 weeks, if anything, i feel better. I averaged 3.57 minutes / mile which is just over 15mph i think, and completed just under 11 miles in 43 minutes, my knee did start to twinge a bit though.
Weirdly, my seat lowered itself whilst i was riding, so i was in a bad position for the majority of the ride but didn't want to stop to adjust it. I must not have tightened the allen bolt when i changed it last.
