Last Sunday I completed my second double century in 15 hours and 30 minutes. It felt great. I felt great pretty much the whole ride, except for the part where I twisted my knee when I came to a stop quickly and had to unclip quickly. I felt a little twist when it happened, but didn't think much of it. Around mile 160, it became clear that twisting my knee was reaping some unfortunate ramifications, including some knee pain. I managed to complete the ride, but couldn't walk for 2 days. The good news it that my doctor says although I have obviously caused some trauma to the joint, there is no instability and he does not believe there is any serious tearing of any ligaments or minisci. My knee was tender upon touching it, swollen, and had almost no range of motion. My doctor says 2 weeks off the bike with medication and it will be back to normal. He did okay me to swim and walk, with a brace, so I'll be relying on those two forms of exercise to keep up my fitness during these two non-cycling weeks.
Can't wait for the next double century! Hoping to get the time down to 14 hours total time!
