Deadly Dozen vs Mud Masters : distance, stations, prix et difficulté comparés (2026-27)

Deadly Dozen is a hybrid fitness race that began with a track race in Macclesfield, England, in mid-2024, founded by Jason Curtis. In the original Track Race, athletes alternate twelve 400 m runs, called Journeys, with twelve functional exercise stations, called Labours, for 4.8 km of running in total.

Athletes can race solo, as pairs who share the Labours, or as a relay team taking turns. Alongside the Track Race, the brand runs Deadly Sprint, Ultra and Hybrid formats, a youth race, a swim edition and gym-based races, including strength and barbell formats, through affiliate gyms. UK track races are held at athletics venues such as Lee Valley, Sheffield, Middlesbrough, Bristol, Macclesfield, Edinburgh, Crawley, Liverpool and Portsmouth, and the organisers say the network now spans 44 countries. First-timers are welcome, and the movements are designed to be accessible while still demanding.

Mud Masters is an obstacle run organised by Mud Masters B.V. of Utrecht, held since 2012 at venues in the Netherlands and Germany. Current events include Haarlemmermeer and Biddinghuizen in the Netherlands and Airport Weeze in Germany, each running over a weekend. The organiser reports around 60,000 finishers per year.

The course is inspired by military training courses and built around teamwork. Distances run from 6 km (13+ obstacles, average finish time about 1 h 15 min) through 12 km (23+ obstacles, about 2 h 30 min) and 16 km (30+ obstacles, about 3 h 15 min) to a 42 km option at selected events. Obstacles include walls, monkey bars, rope climbs, tyre flips, mud crawls and ice-water baths, and routes change every season. Each weekend also has a Family Edition, and there is a finish festival after the race. The shorter distances suit first-timers and groups; the 16 and 42 km courses are for well-prepared runners.
