Well in March was the 2nd running of the Ultra Quest. The 40+ miles of singletrack and 12,000 ft of climbing (including a lot of hiking) is an all day epic for some. Finishing in 8hrs 12min last year, I felt that if I drank and ate smarter than I had last year that I would finish better. Well, my body had other plans. Leg cramps started twinging at about 2 1/2hrs in and it pretty much went south from there. At over 10hrs on a hot day I was worked and barely moving, and decided that I couldn't go on even though it was a "short" 45-60min to the finish. But since only 26 finished out of 46 who started, I was only extremely disappointed (instead of severely disappointed).
Here I am about the only time I was really having a good time, on the Carbide tripoddin' down the first sketchy dh of the day.
