What is INSCYD? INSCYD is a remote, protocol-based physiology test that has been validated for accuracy against laboratory-grade physiology testing. Professional athletes and WorldTour cycling teams use INSCYD to test and monitor their training progress. 

What does INSCYD reveal? INSCYD testing reveals your complete metabolic profile, your load characteristics, your training zones, and your metabolic footprint. Knowing these personal traits can inform your training approach, your top priority workouts, and your race/event strategy.

Reserve an INSCYD 4-pack and after your first INSCYD test, you will meet with our Head Coach and Physiologist Ryan Kohler for an in-depth analysis of your results plus recommended next steps in your training.
