Nutrition during an ultra when your gut is already wrecked from night shifts how do you figure this out?
My GI system has been through a lot. Years of night shift eating has basically trained my stomach to accept food at completely random hours without complaint, which I thought would be an advantage going into ultra training. Turns out a 6 hour training run on trails is a different kind of stress than scarfing down hospital cafeteria pasta at 3am
I track nutrition pretty obsessively and still cannot nail down a fueling strategy that holds up past the 3 hour mark. I do fine early, then somewhere around mile 15 or 16 everything gets unpredictable. Gels work until they don't. Real food sounds good in theory but I've made some bad decisions at aid station tables that I won't repeat
What I'm trying to figure out is whether people land on a strategy through actual testing and iteration or whether it's mostly race day luck and gut adaptation over a long training block. I've read about training the gut like any other system but I'm not sure how seriously people actually do that in practice versus just saying it
What clicked for people who went from marathon fueling habits to actually managing nutrition across a 50k or longer? Was there a specific change that made the difference or did it just take a lot of miserable long runs to sort out.
