Receive a Biological Age & Performance Report
Your VO₂max, ventilatory thresholds (VT1/VT2), precise HR/pace zones for easy, tempo, and intervals, lung capacity and utilisation, fat burning efficiency, recovery capacity and health vs biological age.
Track real progress (and health)
VO₂max is a powerful marker of endurance and health—watch it rise block-to-block alongside your PRs.
Make your watch smarter
Calibrate Garmin/Apple/Whoop/Pelaton. with lab-derived HR/pace zones so daily guidance matches your physiology, not generic estimates.
Fuel longer runs smarter
See where you switch from fat to carbs (RER/FatMax) to plan fueling and go longer without bonking.
Escape the grey zone
Set a true Zone 2 to build endurance faster, recover better, and stop wasting miles.
Nail your paces
Get VO₂max and ventilatory thresholds (VT1/VT2) so “easy/tempo/interval” becomes exact speeds you can hold for 5K–marathon.
