Carbohydrate Utilisation Test
Personalised Fuel Use. Measured, not guessed.
The Exogenous Carbohydrate Oxidation Test allows us to measure how much of the carbohydrate you consume during training and racing your body can actually use for energy. This removes guesswork from fuelling and replaces it with precise, performance-led data.
What This Test Tells You
- Exactly how many grams of carbohydrate per hour your body can absorb and burn
- Whether you are under-fuelling, over-fuelling, or mismatched to your gut tolerance
- Why you may be experiencing energy drops, bloating, cramps or nausea in longer sessions
- How to optimise gels, drinks and race-day nutrition based on your physiology
Who This Test Is For
- Endurance runners
- Cyclists and triathletes
- Long-distance team sport athletes
- Anyone struggling with race fuelling, gut issues or late-stage fatigue
