Every HYROX race follows the same pattern: run 1 km, complete a station, run 1 km, complete the next station, until all eight stations are done. The order never changes, so the race finishes with wall balls after the eighth run. Between the running course and the stations sits the Roxzone, the transition area every athlete passes through on the way in and out of each station. Time spent in the Roxzone counts toward the total.
There are four singles divisions: Women, Women Pro, Men and Men Pro. Athletes start in waves with their own division. Doubles and relay races use the same stations but have separate rulebooks for how the work is shared.
