Update: I managed a 42.5 miles this last Sunday. Mostly flat terrain and I was out of gas at the end. Does anyone have trouble eating solid foods during a metric century? I tried the "Cuties" on Sunday and towards the end they bothered me a little. I use the GU packs on longer rides and they seem to keep my legs from cramping.

Any ideas as well on the best Chamois Cream a.k.a. "butt butter"? I am going to try for 45 miles or maybe a little more on Sunday if the weather will cooperate. Thanks for the help.
