I went down to Fountainhead today to get one last technical mountain bike ride in before I start training for the 24 hours of Booty.
I was hoping that I'd finish the 8 mile loop in under 2 hours and then I would complete a second lap. The first hour was rough, I was sweating profusely since I am not heat acclimated and my heart rate was through the roof. I managed to complete the first lap in 2 hours, but somewhere after Shock-a-billy, I had my chain get sucked up between the wheel and the rear cassette. I got it back on, but noticed that the second largest cog was smashed up against the largest cog in places. It still worked reasonably well, but I didn't want to chance another 8 mile loop of mis-shifting (it was bouncing in and out of gear especially when I really needed it) and a potential chain break (from the stress).
I only fell once. Had a blast.
