Don鈥檛 stop fueling. Your body wants simple sugar, and about 250 calories worth of it an hour. For most people, taking it in small doses, like a Shot Blok, or part of a gel, works best. If you鈥檙e not in to processed energy foods, candy, dried fruit, or small snacks like PB+J can substitute. It鈥檚 wise to test what works best for you on long runs before your race.
Drink throughout to help yourself digest, and don鈥檛 forget to recover, refuel and rehydrate after the race, too. A popular 2007 study from the University of Granada in Spain found that beer (as long as you鈥檙e drinking water as well) can be a good recovery beverage鈥so long as you’re not planning on running another race shortly thereafter.
