I usually eat something highly carby the night before a long ride (usually pasta). The morning of the ride I eat a bagel of some sort, a nice big glass of juice and a coffee. I take with me a couple boiled eggs (and a little salt in a baggie) and a pack of peanut butter and cheese crackers. I keep one water bottle with water, the other with Gator-aid. Depending on the weather and the difficulty of the route (lotsa hills or not), I may not even eat all that I bring with me. I *always* keep a packet of Gu in my under-the-seat wedge just in case I really bonk and need a little something to get me to the next rest stop or home. It took me a while to find my food-to-energy balance, but I find I don't need to eat nearly as much/as often as I did when I was just starting out.
