Back to the food, and another vote for beef jerky in the middle, or the back end, of a long ride. I can't stand the stuff normally, but there's something about easy-to-chew, super-salty protein that works for me. Eggs, bikes and me are just not a good combination, my stomach goes into can't cope mode and I suffer.

Another "does-not-work." Ice cold chocolate milk mid-ride. Works just fine at the end, but afterward?
