For runs up to like 10 miles I'll sometimes grab a few handfulls of Cheerios. Yes, I eat them dry and chase them with water. They seem to be the only food I can eat w/o having a reflux problem during my run.
For longer runs10-15 miles I like to have sushi the night before. For me, there seems to be a good combo of carbs from the rice protein from the fish that gets me through. This seems to work out great for me and I can usually go without anything but good ol' water during those runs. (I do consume an inhuman amount of sushi though. One California roll will not do it.)
9.9 times out of 10 I just try to eat a well balanced meal the night before. Rarely will I eat anything before a run and if I do it has to be a few hours before. My once cast iron stomach is getting rusty.
(Edited for clarity of my thoughts)
the night before...Dinner?
Seriously though, 2 - 4 miles of running you will still be burning blood sugar.
You will be fasting over night so your meal the night before for such a short run is really irrelevant. After 2-4 hours your body will have digested the carbohydrates from your food and any excess will be stored as glycogen or fat. Your body will maintain your blood sugar on its own and then when you run in the morning you will mobilze stores of glycogen and fat as needed.
You don't need to eat a whole breakfast in the morning. Have you considered having a 6-8 ounce glass of 100% juice? This will give you 80-120 calories of pure sugar (and nutrients if you choose 100% fruit juice) which will give you energy for running. Something like apple or grape juice should be light on your stomach (as opposed to orange or cranberry juice).
