What did you eat on IM run?

Gatoriad, water, cookies, pretzles, 1 power gel.  No tummy troubles.

GU gels.  One about every 45-50 min.  I drank about 3-4 oz of Gatorade and 3-4 oz of water at each aid station (needed to dilute the Gatorade a bit in my tummy).

(And, I must confess, since I was injured and cranky going into the race, I also indulged in the mini Oreos I discovered they had at all the Vineman run aid stations.  Yum.)

Cookies, pretzels, broth, orange slices, and a little (very little) gatorade.  I'm usually able to eat just about anything, and throttling back on the intensity (due to my injury) helped keep GI issues away.  I'm not a huge fan of Gu's, Gels, Powerbars, or sports drink (they are convenient for long runs, but I'm willing to bring a banana, Payday candy bar, granola bars, nutrigrain bars, etc. with me on the bike to get calories). 

Try pretzels, cookies, and broth (maybe the flat Coke/Pepsi) and see how your stomach accepts them. 

Edited to add orange slices. 

Make sure you have sufficient water with the gels.  For marys and HIM runs, I've used Gu and make sure to get ~8oz (two of those little cups) for each Gu pouch.  My strategy is to rip open the Gu when I see the water station coming up, power down the Gu, then get two cups of water to wash it down.  Otherwise my stomach can't handle the Gu.

my plan was to just do gels and water...maybe the gatoraid endurance on the run.  I did those three but also coke at every opportunity and it wasn't flat.  also, some pretzels, crackers and oranges.  Coke was the best stuff ever!  No stomach issues.

My "plan" went out the window and I just ate off the course and what looked good to me. Bananas and gatorade is what I craved the first part of the marathon but towards the end chicken broth was KING!! I could not stomach a gel.  I also had tums in my back pocket just in case.  Best of luck!!

Oh, and potato chips Rocked on the bike!! Something about the salt and crunch. I remember thinking that was the best thing I had all day. I threw them in my special needs bag at the last minute and I'm so glad I did.

I had no nutrition plan for the run...just figured I'd go by what my body was telling me. I ended up having gatorade, water, pretzels, oranges, and chocolate chip cookies. Although, I was bummed because I started craving the cookies around mile 15 or so, but all the aid stations were out of them. Then, I got to like mile 23 or 24 and I no longer wanted one, but they had plenty. I figured I spent the past 9 miles running to find them, so I might as well take one .

No stomach issues.

Anything that looked good and didn't come in a gel pack!!!  I had trained with them but after the bike I was just "ready" for something (anything) else and so I just ate and drank---water, Heed, bananas, oranges, pretzels...no stomach problems either!
