Train your gut: Practices during training runs are crucial. Try this feeding schedule during your long runs to adapt your stomach to absorbing these volumes.
Fluid Match: High carbohydrate absorption ratios require adequate fluids to clear the stomach. We advise chasing every gel with a few sips of plain water.
Pacing Disclaimer: Calculations are based on a steady pace. Running hills or fighting headwind increases metabolic output and energy requirements.
