Know your body.Train measurably better.
Your physiological profile from a single field test: Critical Power, training zones, a clear development focus. Evidence, not hype: every number with its origin, every recommendation with its data.
A performance lab thatruns on your ride data.
You ride one short test on your own roads. You upload the .FIT file. Minutes later you have the profile a lab measures on an ergometer: every number traced to a published model, every recommendation to your own data.
From Ride File to Report
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 lab test, and ours
The same models from the same peer-reviewed research. The lab measures them directly; we derive them from your ride: which is why it costs a fraction, and why you can actually repeat it.

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 spiroergometry. The model shows strong agreement with measured VO₂max values (R² ≈ 0.77; standard error ≈ 4–5 ml·kg⁻¹·min⁻¹) and uses your CP and W′ as inputs (after Sitko et al., 2021).
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 clear training focus & development direction: everything a coach would extract from a lab test.
