Congratulations on a great ride, Chuck! Time to go for the Guinness record. Yes, from your description it sounds like you shorted yourself on food during the ride. I’ve seen you eat! Maybe you can ride down to MUni Weekend on Friday and give us a break in the big Saturday race by being tired! 
Now you’ve made me hungry for tacos. I know where I’m going for lunch…
The existing Guinness 100 mile record was set on a cycling path of some sort. Off the top of my head, I know the path was very level, and the course involved many times going back and forth, I think with sharp U-turns at each end. It was August 1987 in Tokyo, so the weather was warm but I don’t know the details. Takayuki Koike was 18 years old, and rode the entire 100 miles without a dismount. If he has any feeling in his private parts now, 21 years later, he’s lucky. 
His unicycle was a 43" air-tire unicycle with short cranks. Not sure how short, but I do know those old rickshaw wheels made today’s Coker wheels seem light as a feather.
