Are More Carbs Always Better for Running Performance? | #42 ft. Jonah Rosner

In this episode of the Critical Oxygen podcast, hosts Philip Batterson and Jonah Rosner discuss the importance of fueling for running and the optimal carbohydrate intake for endurance athletes. We share our personal experiences with fueling during training and races, emphasizing the need for proper fueling to support performance and recovery. We discuss the recommended carbohydrate intake for different durations of exercise and the potential benefits of higher carbohydrate intake. We also highlight the importance of individualization and practice in finding the right fueling strategy for each athlete. Additionally, we explore the sex differences in carbohydrate intake and the implications for female endurance athletes. TAKEAWAYS 1) Proper fueling is essential for optimal performance and recovery in endurance athletes. 2) The recommended carbohydrate intake for endurance exercise is typically 30-90 grams per hour, depending on the duration and intensity of the activity. 3) Higher carbohydrate intake, up to 120 grams per hour, may be beneficial for endurance athletes, especially during longer and more intense workouts and races. 4) Individualization and practice are key in finding the right fueling strategy for each athlete. 5) There may be sex differences in carbohydrate intake, with females potentially needing more exogenous carbohydrates compared to males.
