For morning rides (and my morning rides tend to be 45 miles or longer), I usually eat a bowl of oatmeal and a cup of yogurt. I may throw a banana in there, too, if the ride is 60 plus miles. For afternoon rides (which tend to be in the 25 to 30 mile range), I usually just eat a well balanced lunch. I may eat something small an hour before the ride, but I usually don't need to.
