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

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.
