Diet of a Marathoner

I am assuming that plates of cupcakes are out of the question.

As I look forward to the many runs leading up to and including Chicago, I wonder about my eating habits. Pat has suggested that I am sure to stay hydrated - especially important for us Coloradans. Yet, I am also looking for a diet regimen. Does anyone have any suggestions of websites or downloads for diet programs. Maybe an article you have read in runner's world?

I am considering keeping a daily log of what goes in and at what times. Then keeping track with how that day's run went. I think this will help tell me what foods MY body is craving for the long run.
