Help me figure out a new pre-race/long training day breakfast mix

Alright guys, I'm sick of the ceareal/oatmeal/eggs for breakfast before a race or long training day. I know I can get away without much more than gatorade before a sprint, but I do want to have something in place that I've tried out as many times as I can prior to my HIM in May. I was thinking maybe a smoothie type of drink (obviously not very thick) involving fruit (banana/blueberry/strawberry) and a small amount of milk. Other than that, I'm not really sure what else to look for when putting this smoothie together. I suppose maybe some sort of pre-race mix but I'm not very familiar with any other types if they don't start with Gatorade and end in Endurance. Also, not really sure about how many or how much carbs, sodium, sugar, etc. I should be looking for. Just for reference, I'm about 6'1 and 200 lbs. If any of you have any ideas or suggestions, I'm all ears.
