One Race.
Many Formats.

Track-based endurance. Gym-based strength. One global fitness racing system.

Deadly Dozen began in Macclesfield as the world’s first fitness racing Track Race. What started as a single event has grown into a global movement, now racing across multiple countries while staying true to the same accessible, universal, and scalable format that defined the original.

Track Race

At its core, the Deadly Dozen Track Race is deliberately simple: 12 × 400m runs paired with 12 Labours. No technical barriers. No complex rules. Just honest work, repeated under fatigue.
Race it your way:
- Solo — the ultimate individual test
- Pairs — share the Labours and push together
- Relay — teams of four, one Labour per rotation
The entire Deadly Dozen Track Race was completed while wearing a weighted rucksack. It is a more demanding, more challenging endurance test for athletes seeking greater challenge. (10 kg Male/6 kg Female)
A fast, brutal mile-long challenge: 400m Lunges + 400m Burpee Broad Jumps + 400m Bear Crawl + 400m Run. Not the whole Track Race — but every bit as demanding.
A scaled version of the Track Race for 12–15-year-olds, featuring all 12 runs and 12 Labours at reduced volume and weight. Guardians must be present.
A 12-hour ultra event where athletes attempt to complete 12 full Deadly Dozens within the cutoff. Enter as Solo, Pair or Relay.
One of the hardest hybrid events in the world.
