Going back to the OP's post -

We've been discussing a lot of things. We haven't talked too much about the OP's goal of riding cross state bike rides (plural)! And good on her. I think most of us agree that some whey protein in the morning and evening is a good idea. A buddy of mine swears by a recovery meal of steak and wine, but that's out of the question here. And I think her real preference is steak, chocolate, and wine.

There's also the bigger question of eating underway on all-day rides. Here's my .02: Ensure Plus! If you drink a can about every other hour, that should about do it. Otherwise, just water and Endurolytes. Check the label for ingredients and percentages - that's where you'll get most of your protein. And I've never heard of a rider barfing it up. Very popular on killer rides like the Furnace Creek 508 and RAAM. This year's 508 winner drank 16 cans in about 24 hours. It's not too hard to carry a couple cans with you, and refill in towns because almost every grocery store has it. Try it in training as your rides get longer in the spring.
