alt Hacker NewsWow so he was absorbing 400 calories per hour with this gel, but he was likely burning 3-4x that amount (or even more) while running 13.1 miles per hour!

Your body stores roughly 2000 calories in glycogen. They are burning calories but nowhere near the amount a middle pack would be at this pace.
So ~2800 calories of carbs with some fat being burned.
In a two hour race that’s still 800 bonus calories, that’s something.
The race to tolerate lots of carbs is usually something you think of in 8 hour Ironmans. The good part is you can do most of it on the bike, which is much easier to eat as you go. As far as I know, many elite runners were doing like 50% water, 50% sports drink and consuming way under 100g.
