But if I were going to do that, then I would think about stacking carbohydrates, ketones, and fats.
there's a bunch of different strategies if you're going to go really long like some of these um like cycling where the races will be several hours then you actually might go to some fat as fuel sources I I know a lot of cyclists are using ketones and things like that now but traditionally most endurance folks are going to bias heavily towards carbohydrate
