Your first fitness race
Start with the Deadly Sprint: the Deadly Dozen cut in half - twelve 200m runs, half the reps, the same weights. The name is the distance, not the pace: jog it, run it or sprint it.
START HERE
Anyone aged 18 or over on race day. First-timers are welcome, and nobody expects you to sprint: the clock simply records your time on the global leaderboard, next to everyone who raced the same format.

HYROX is a trademark of its owner, which has no connection with Deadly Dozen.
