Kristen Faulkner building her own performance model from nine years of data is a sharper sports tech signal than another wearable dashboard launch.

The useful detail in the Cycling Weekly interview is that she is pulling heart rate, HRV, sleep, weight, power, menstrual cycle phases, DEXA scans, and race context into a system she writes and audits herself, after winning three Pan Am golds and hitting best ever 20 minute power. Elite sport has been drowning in sensors while outsourcing interpretation to generic coaching software built around average bodies and male biased datasets.

This is the better direction. The athlete becomes the integrator. Models make physiology, judgment, recovery, and training folklore submit to repeated measurement. The old coach's eye survives, but it gets dragged onto a harder instrument panel.
