Study how elites pace every distance — or load your own finish-line video and mark splits against the same models.
Study how elites pace every distance — or load your own finish-line video and mark splits against the same models.
Eleven events from 100m through 5K plus hurdles: elite split databases, interactive charts, pacing calculators, and confidence bands — all grounded in historical races.
Upload a clip from your phone or camera, sync the gun, tap segment splits while a race clock runs, then compare to elite pacing. Nothing leaves your browser.
