Chris, I saw this thread and wanted to post what Kim Brown posted in the infinIT forum about your topic. Hope that is OK.

"Hi Chris,
Running is always going to be a bit more jarring on the stomach as compared to non-weight-bearing activities such as cycling and swimming but don't worry, your marathon training is not a lost cause.
You are doing the right thing in experimenting with different foods right now. Just on what you told me, going off on a long run with merely a gel in your system or quite the opposite (a couple burgers) is not the best scenario. In general, you should aim at consuming 400-600 calories 2 hours before and you can even experiment by splitting the calories up. Aim at ~1 gram of protein per 4 grams of carbohydrate ingested. Avoid consuming more than 20 grams of protein, 10 grams of fiber, 15 grams of fat in the 2 hours prior to as excessive amounts of these nutrients tend to slow down digestion and can increase the likelihood of you "trottin" to the bathroom rather than to the finishline. You also should try to eat your dinner the night prior to running a bit earlier (at least 3 hours before bedtime) and this meal should be carb-focused and light on fat/protein/fiber (e.g., spaghetti with marinara sauce). Some common pre-run meals (morning of run) include:
1) My pre-race meal of choice: Purefit bar (
http://www.purefit.com) plus 1 banana taken 2 hours before with 16 ounces water. In addition, I sip on 16 ounces of a salty sports drink (my InfinIT solution) in the hour leading up to the race.
2) A little smear of peanut butter and sliced banana on 2 slices toast.
3) Special K cereal with nonfat milk and berries.
4) Plain instant oatmeal topped with banana, a sprinkling of nuts, and nonfat milk.
5) Low fat yogurt topped with berries and granola.
Hope this helps!
Healthy regards,
