What to Eat Before a Race, from the 5K to Marathon

Tread Lightly Running Podcast

Carbohydrates, caffeine, and water (sometimes with electrolytes): these seem so simple, but they all improve performance when taken before a race. In this episode, we discuss how to structure your pre-race meal before a 5K to marathon, including what to eat, how to time it, and how to avoid GI upset.
