From Ride File to Lab Report

01

Do the Test

2 maximal efforts separated by at least 6 minutes, or the classic 5'+20' protocol, or a short all-out for the Quick Test. Pacing, fueling, and consistency between retests all matter — the full protocol walks you through each option.

The numbers don't lie.

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.

Validated against laboratory gas-exchange testing — within ±2% of lab values across our validation cohort. The model is calibrated to your performance tier and uses your CP and W' as inputs.

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.
