In this episode, we take a deep dive into carbohydrate fuelling, discussing glucose–fructose ratios and what they mean for endurance performance. We break down the science in a practical, easy-to-understand way, explaining how different ratios influence absorption, energy production, and overall fuelling strategy.

We also introduce our new 1:1 PROTO range, discussing where it fits, who it’s for, and how it compares to the more traditional 2:1 approach. This isn’t about simply consuming more carbohydrate, but about fuelling appropriately for the demands of your training and racing.Whether you’re aiming for 60g, 90g, or pushing beyond 120g per hour, this episode will help you better understand how to fuel effectively and confidently.
