I should practice wearing my running vest in races leading up to the Bandera 100K, but I’m nothing if not a pragmatist. The 2024 Boulder Marathon has aid stations every two miles and they are stocked with really, really quality gels and hydration. A rarity. And I wear my vest plenty on my long weekend runs.

So I’m going to enjoy running naked. I’ll eat the SIS Beta Fuel gels and drink the Mortal Hydration mango electrolytes at each aid station. My fueling plan is below. Each aid station cup is about 150 ml but I’ll plan on getting an even 100 ml out of them. The water bottles in my vest are 500ml. I’ll target drinking two cups at each aid station.

It’s just so unusual for a race to offer such quality fuel. And SIS Beta gels are one of the gels I plan to consume at Bandera, so while I’m not practicing wearing my vest, I’m still eating the gels I need to test out. Not sure if I’ll drink Mortal Hydration, but this marathon will be the perfect opportunity to test that out as well.
