Here is what I found in Runners Magazine:

"One of the biggest nutritional mistakes I see runners making is back-loading their day", says Nancy Clark, author of Food Guide for Marathoners: Tips for Everyday Champions. Clark notes that even experienced athletes often eat too little at breakfast and lunch, only to find themselves famished in the evening hours. The result? Erratic running performance. Instead, start your day off with at least a400-600 calorie breakfast that's high in carbs but also offers some protein and good fats. Think oatmeal with a dollop of yoguart or some trail mix with nuts and raisins.
