I'm sure others will make a post with valuable nutritional information, , but from a practical standpoint, I would recommend something you have you have eaten before and your stomach will still feel fine in the morning. I would also plan extra water to make sure you are well hydrated before the race. Also on race day, no new foods, snacks supplements, drinks etc. Only use previously tried supplements, and you know how it will affect you!

I pretty much always go for grilled chicken and brown rice; I know it will fill me up but not too much and won't upset my stomach the next morning.

I echo the lean meat and a carb. I feel that the morning meal is just as important though because it will be the first energy your tap during the race. I do a plain bagel with lots of peanut butter and honey!

Agreed. I also have a ton of friends that go with Ensure as the mainstay of a prerace morning meal.

A good morning meal will make your race great. A bad one will make your race misery. I'm a huge fan of eggs, veggies, and whole grains for breakfast, but not on race day. On race day morning, I'm all about granola, oats, whole grain breads/bagels, stuff like that. Clif bars go down well for me.

Also, for what it's worth, I never purposefully carbo load the night before (Although when I'm with a group we do generally tend to go to pasta places. Groan.). If I carbo load, it's 2 days out. And not a huge pig-out, either. Just a standard sized meal. My favorite is spaghetti with mushroom sauce, or pad thai with an unsweetened boba tea.

^^^^^^ Hope to see a Race Report on your HIM - good luck!
