Hyrox exposes mat-level splits for every finisher, back to season 18/19
Every HYROX finisher since the 2018/19 season has split-level data sitting openly on the official results portal, with run legs, station timings, and RoxZone transitions recorded separately. That is roughly 100 events a year and hundreds of thousands of athletes, retrievable without auth through the mikatiming platform. A clean endurance-performance dataset for pacing, transition, and station-composition analysis that most people never knew was public.
