Description
Your performance isn’t defined by how fast you can run today — it’s defined by how efficiently your body produces and uses energy. The INSCYD Performance Profiling Test reveals the full picture of your physiology so you can train with purpose and race with confidence.
What you’ll learn
Your aerobic engine capacity (VO₂ system)
Your anaerobic/glycolytic power (VLamax)
Lactate thresholds and recovery dynamics
Fuel usage — when you burn fat vs carbs
Your optimal race pacing for road and trail
Exactly where your biggest gains will come from
This is the same technology trusted by world-class marathoners and ultra runners.
Integration that drives real results
Your results are fully integrated into your TrainingPeaks account:
✔ Updated pace, heart-rate and power zones
