- Hey, curious how you tracked the %gain? They seem super high, which is entirely possible for people who didn't take they nutrition as seriously before if you managed to get them fully on board with the app.
And something I'm totally unfamiliar with, how does someone "gut train"?
It's an interesting angle for a training app as this is definitely a recurring issue in the endurance world, good luck to you!
by Luucas40 - Hey! The % gain is self-reported, from post-race surveys we push to users. So it's not a controlled before/after, more a proxy. Worth flagging there's selection bias too, the users motivated enough to fill out a survey after finishing a race were probably also the ones who stuck with the plan.
Gut training is basically progressive overload for carb absorption. Your gut has a ceiling on how many grams of carbs it can process per hour before you get GI distress, but that ceiling isn't fixed, you raise it by repeatedly practicing high carb intake in training until your body adapts. Almost nobody trains this, then tries to hit 90g/hr for the first time on race day and blows up. It's probably the most skipped part of endurance prep.
