It is also a good idea to carry gels with you, for a quick boost to get you to the next sag stop.
I did an entire century on Perpetuem once. My total consumption was about 70 oz of Perpetuem, 5 doses of gel, and two plain waterbottles. It worked great -- got to the end and felt great. But the taste! Haven't been able to drink it ever since!
This may be the year I go back and do Horsey Hundred again. For a northerner, it's pretty early in the year and it's usually my first 50+ mile ride of the year. Jumping from 30-35 flat miles to 100 rolling-to-steep miles gets me a little tired; but I always have fun.
