This episode of the Female Athlete Nutrition podcast is with  sports dietitian, runner, and mom of two, Meghann Featherstun. As well as helping other athletes with their fueling, Meghann is a rockstar athlete in her own right with multiple marathon finishes. We talk about how she uses her professional knowledge to help her own performance, leading to her best races aged 40 after having kids. We dive deep into marathon and endurance nutrition, focusing on pre-race nutrition. Meghann gives listeners great travel nutrition tips, as well as advice for dealing with gastrointestinal (GI) issues. Meghann and I talk all about carbohydrate loading: the what, why, when, and how. We then focus on understanding your hydration needs by measuring your sweat rate, and the importance of replacing sodium losses, avoiding over- and under-hydrating. We bust some myths around sodium fears, weight gain during a carb load, and emphasize the reality that athletes likely need more carbohydrates than they think. To better understand your unique carbohydrate and hydration needs, Meghann has some amazing resources: Meghann’s quick carb calculator and sweat rate/ hydration calculator.
