At the metric century ride I did we had really nice bagels (sticky, kind of a raisin/cinnamon type) and whipped cream cheese. Peanut butter and Jelly, bananas, grapes and granola bars.
I wish wish wish they didn't use peanut butter though...I am deathly allergic as are many people. The peanut butter knife gets into the jelly making it useless for me, so I had to stick with the cream cheese.
If only they used almond butter!
