I was looking online for recipes for bars to make for rides; my husband turned up some high-falutin' snooty super training geek who said to eat Pop-Tarts, and from that moment on, we've just been eating normal food that we like on rides. Mostly a variety of baked stuff--on the healthy side of the typical US diet, but not clear to the healthy end.

But we're only newly reformed middle-aged duffers. Anyone with serious training in mind might be better off with PopTarts!
