What this episode covers
Carb loading is one of the most misunderstood — and most stressful — parts of race week. In Day 6 of the Countdown to Dopey, Coach Jill Bartholomew breaks down what carb loading actually is, what it isn’t, and how to approach it calmly and intelligently without panic, force-feeding, or scale obsession. Drawing directly from research published in the Journal of Sports Sciences, this episode explains how carb loading works by increasing muscle glycogen stores, why glycogen is the primary fuel source at marathon and sub-marathon intensities, and how proper fueling allows athletes to access the fitness they’ve already built for longer. Jill also covers evidence-based carbohydrate intake ranges, why temporary scale weight changes are normal, and how much above normal intake is typically optimal for recreational endurance athletes. This episode walks through practical, real-world guidance for Dopey Challenge athletes, including: When carb loading actually matters during race week Why aggressive or early carb loading can backfire How to choose familiar, boring foods that support digestion Common mistakes like panic eating, drastic diet changes, and overhydration Why doubling or tripling water intake can be dangerous How to fuel confidently without comparing yourself to other athletes If you’re racing the runDisney Dopey Challenge and feeling overwhelmed by conflicting nutrition advice, this episode will help you separate science from rumor, fuel with confidence, and support your body without unnecessary stress. Carb loading isn’t a test you pass or fail — it’s a calm, supportive process that sets you up to execute on race day.
