Personalised Carbohydrate Load GuideMost 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

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.

Durable and great color
Color: Orange, Color: Orange
I’m so happy with these orange tennis balls! They’re the perfect size for Roxy’s ball launcher, and the bright orange color makes them super easy to find—no more losing them in the grass! Roxy goes wild for them, and they’re holding up really well even with all her chomping and fetching. If you’re looking for fun, durable balls that stand out, these are a winner!

Cheap but good for what we do!
Color: Dark Blue
I wouldn't play tennis with them -- not that quality. However, we use a chuck-it thrower for our pooch and it's the perfect ball. When she's rips them open it's no big loss. Chinese.

Good Quality but Lose Bounce Over Time
Color: Yellow
Solid tennis balls overall, but after a couple of weeks of daily use they start losing pressure. Still a great deal for casual games or practice.

My dogs are obsessed with these
Color: Multicolour, Color: Multicolour
Red, Molly, and Karma are absolutely obsessed with these tennis balls. They’re bright and easy to spot outside in the grass, hold up surprisingly well during rough play, and don’t immediately shred apart like a lot of dog toys do. Great for fetch and everyday play time — definitely a favorite in our house.
