Train for success

The Right Fuel, Right Time approach overlays specific fuels to your specific training to accentuate metabolic adaptions for your targeted competition. Research has shown that for endurance sports, fat-oxidation efficiency is a key determinant factor of performance outcomes.

By preserving glycogen through efficient fat-oxidation, you build resilience for high-intensity race finishes. This approach is designed with three targeted benefits:

Stronger Aerobic Base:

Optimize aerobic adaptions.

Stable High-Intensity Finishes:

High-intensity glycogen preservation and fuel efficiency.

Strong Resilient Gut:

Trained gut resilience and rapid carbohydrate gut transit.
