Earlier this summer, I was quoted in an article from Outside Run titled " A Sports Dietitian’s Guide to High-Carb Drink Mixes. " With the recent hype of professional endurance athletes consuming between 120-180g of carbs per hour while racing, it's important to know that more is not always better. Like your muscles, the gut is adaptable. You can train your gut to increase its ability to absorb and tolerate carbs when training and racing but it takes time and repeated exposure. Don't expect your stomach to tolerate 100g carbs per hour on race day if you have only been training with 50g carbs per hour. For more info, check out the article here.
