SAFD:
Pre-race: toast (or similar) with peanut butter and then an oatmeal for later (this is super easy to put in a disposable coffee cup and bring with me to the corrals, although it will be cold by the time I get around to eating it.)
5k/10k: I don't fuel. One water and one powerade at each aid station.
Half: One water and one powerade at each aid station. 2-3 "energy" things (gu, huma, stroopwaffle, etc) approximately 1 every hour, depending on how I'm feeling. I bring food in my gearcheck bag and eat something as soon as I get through the finish chute and can get to my bag, usually a PBJ. If things go well, I try to eat a big lunch. If things don't go well I try to nibble on snacks all day, and I'll eat anything that sounds good. This is because if things aren't going well I will have zero appetite and really struggle to eat anything for the rest of the day.
Full: One water and one powerade at each aid station. Energy" things (gu, huma, stroopwaffle, etc) approximately 1 every hour, depending on how I'm feeling. Bananas when they are offered. Chocolate when it's offered. I bring food in my gearcheck bag and eat something as soon as I get through the finish chute and can get to my bag, usually a PBJ. Last MW, DH met me by mission space and handed off a donut, which I annihilated after crossing the finish line (so there's a good chance I'll make a food stop coming through Epcot this coming weekend as well.)
Aside from IN-RACE food, I try to eat a bigger lunch, smaller dinner, not too much fried food. If I can manage a vegetable, that's good, but I want to be taking in calories, not just filling myself up (if that makes sense.) I don't do any kind of formal carb-loading, but I do give myself permission for more starchy things in the 3 days leading up to the half and full marathon (hello, bread service at sanaa or nomad lounge!) The longer races can really shut down my appetite, so I'll eat almost anything on Saturday.
I do try to limit myself to one adult beverage per day when I have a race the next day. (Parking lot pineapple ciders don't count.)
