If I am going on an early morning ride, just to get my riding time in, I eat a Clif Bar and drink half a glass of OJ. Before I commute (very early, I get up at 4:30 and leave around 5:30-5:40), I eat a cup of organic whole wheat cereal, with some plain yogurt mixed in, along with some almonds and dried cranberries. Also have some juice. Then I eat half a Clif bar when I get to work. I have to have coffee within a pretty short time of arriving/getting home, though. If I am going on a ride later in the AM, I eat a good breakfast of 2 eggs, scrambled, a whole wheat bagel and some fruit. I often will drink tea on these days, to get the caffeine, but not the annoying runs to the bathroom that happen when i drink coffee. So, if I'm leaving on a ride at 10, I eat breakfast at 8. When I did the century last year, I ate at 5:30 AM and started the ride at around 7:15. I lived on Clif Bars, bananas, Clif Blocks and Accelerade for the ride, since the sandwiches were pbj and I am allergic to peanuts. I can tolerate a small chicken and cheese sandwich on whole wheat for a lunch stop, but not much else.
