Most endurance athletes carb load before a race. Very few do it in a way that actually makes a meaningful difference to their performance. The standard advice tells you to eat more carbohydrates in the days before your event. It gives you a generic range. It treats every athlete the same. And it ignores the two variables that determine how much carbohydrate your specific body actually needs. This guide changes that. Built on the latest sports nutrition research and the same performance principles TFD has applied with elite endurance athletes and world class fighters for close to a decade, this guide gives you a practical framework for personalising your carb loading protocol around your body and your event. You will learn how to estimate your personal glycogen storage capacity from your body composition. You will learn how your race intensity and duration determine your total carbohydrate demand. And you will walk away with a step by step system for building a loading protocol with real numbers behind it rather than a one size fits all recommendation that was never designed for you. Inside the guide: The physiology of carbohydrate storage in the liver and skeletal muscle and what determines your personal capacity How carbohydrate oxidation rate changes with exercise intensity and why two athletes competing in the same event can have completely different fuel requirements A step by step calculation framework for estimating your glycogen storage capacity from your body composition How to calculate your total race day carbohydrate demand based on your specific event and intensity A practical protocol for the loading days including how many grams per kilogram, what to eat, how to structure your intake, and what to do in the final hours before the start line This guide is for marathon runners, half marathon runners, ultra marathon runners, triathletes, cyclists, and any endurance athlete who wants to stop guessing at their pre race nutrition and start building it around their actual physiology. This is not generic nutrition advice. This is performance nutrition built around you.
