I figure right now I'm taking in about 100 calories/hour via my electrolyte drink when I drink at the rate I should be drinking. On top of that, I eat perhaps 500-800 calories over the course of a century. So let's say 1200-1500 calories. At the low end, it gets me through a century just fine, but I do feel really hungry when I'm through. I guess the high end of what I eat now is a bit less than the minimum I'd have to eat on a double century.

During that time of year, you Canadians get some long daylight hours being so far north! I'm eyeing a ride in February. I'd definitely need lights.
