Your complete physiological profile from a single ride.
Upload from any cycling computer. Get VO₂max, Critical Power, training zones, and a personalized strategic directive — in under 4 minutes.
Built on Science, Not Guesswork.
Our validated methodology outperforms every existing method — tested and validated through rigorous scientific study.
Advanced Profiling
A precise approach to Critical Power estimation from a single ride file. No multi-day testing protocol required.
Metabolic Profiling
Derives VO₂max, fractional utilization, and W' from power data alone — metrics that normally require a lab.
Strategic Directive
Tells you exactly what to focus on: raise your ceiling (VO₂max) or improve your threshold. No ambiguity.
The numbers don't lie.
From Ride File to Lab Report
Upload Your Ride

Frequently Asked Questions
Any cycling computer that exports .FIT files — Garmin, Wahoo, Hammerhead, Bryton, Stages, and more. Your ride just needs to contain power data.
Yes. The analysis uses wattage data to derive your physiological profile. Heart rate alone is not sufficient for this level of accuracy.
Any ride that includes a sustained hard effort. A race, a hard group ride, or a dedicated max-effort test all work.
Our methodology has been validated against laboratory gas exchange testing. It uses an advanced physiological model calibrated to your performance tier.
Your .FIT files are processed in-memory and never stored on disk. Analysis results are encrypted and only accessible via your unique session link.
Absolutely. The diagnostic provides training zones, metabolic breakdown, and a strategic directive — everything a coach would extract from a lab test.
