I ran into the same problem at RAIN. I'm usually an oatmeal, banana, yogurt girl before a ride. For RAIN, I bought a (rather oversized) muffin from a bakery near my house the day before the ride and ate it with about 2 hours to go before the start of the ride. I then ate a banana and a package of Teddy Grahams about a half hour before the start. At the Horsey Hundred, I ate a Pop Tart when I first woke up and then at the cafeteria about an hour later. For me, it isn't so much what I eat, but when. I find that if I eat something two hours before, followed by something to "top it off," plus drink a bottle of water, I'm good to go.
You could do muffins, banana bread, granola, bagels, donuts, etc. plus a banana. That should do it.
Have a great ride,
Kate
