Found this video the other day of the craziest race ive ever done. 24 hours of Moab. These solo guys are crazy. I remember passing Kelly Magelky in the middle of the night and thinking there was no was going to make it until morning. Immediately after my last lap I felt great, and was ready to sign up for another one. Within an hour I couldnt stay awake and fell asleep on the floor of the Grand Junction Airport. I felt completely sick and exhausted. I dont think i rode my bike for a week after doing this. And I only had to do a lap every few hours. I know an insane guy who did something like 7 of these solo in one year. Pretty much every other weekend all summer.
