Deadly Dozen is coming to K2 Crawley on 8 August 2026, bringing the UK's original fitness race to West Sussex for a relentless test of strength, speed and determination.

The format is simple. The challenge is anything but. Complete 12 × 400m runs, tackling one demanding exercise station—known as a Labour—after every lap. The clock keeps moving from your first stride to your final rep.

Face all twelve Solo, tackle the race together in Pairs, or divide the challenge between a four-person Relay team. Whichever format you choose, the same start line, twelve runs and twelve Labours await.

Race it your way

Pairs and Relays can be Same-Sex or Mixed (Mixed Relay: 2x Male + 2x Female). Mixed Pairs use the Male weights; Mixed Relays use the weights specific to their sex.

Solo

1 Athlete

Just you against all twelve. The purest test of grit — set your time, chase the ranking, earn the finish.

At its core, Deadly Dozen is deliberately simple.

  • 12 × 400m Runs

  • 12 Labours (Exercise Stations)

Twenty-four stations. One continuous race.

No technical obstacles. No gimmicks.

Just honest work repeated under fatigue.

Every athlete races the same format, creating a fair, competitive experience that’s easy to understand—but incredibly difficult to master.
