Maurten is the Official Sports Performance Nutrition of the IRONMAN Global Series.

On-course, all athletes will have access to hydrogel in the form of the Gel 100 and Gel 100 Caf 100. And now, there's more. Starting in 2024, Maurten's Solid — a fast, light, carbohydrate-rich chewable fuel source — will also be available on-course. It's a serving of real texture to break-up your fueling strategy. Your race fueling starts now — in training. Get used to it.

On-course

Fuel like a pro

The following Fuel Guides outline fueling strategies for common triathlon training sessions and race plans. A fuel guide is highly personal. Use this information as reference only to fuel your training and racing better.

Sports fuel is supported by science and works alongside real food — not as a replacement. Some Fuel Guides — longer or more intense — rely heavily on the specific composition of sports nutrition. Others less so.
