GYMRACE vs Nuclear Fit : distance, stations, prix et difficulté comparés (2026-27)

GYMRACE is an indoor fitness race organised by the team behind Mud Masters, which has run sports events in the Netherlands and Germany since 2012. Races are held in large indoor venues in the Netherlands, Germany and France, including Utrecht, Amsterdam, Weeze, Duisburg and Paris.

The course has five 1 km runs, 5 km in total. Each run is followed by two stations, and the race ends with a 50 m sprint. The ten stations are a sled push, wall balls, a slam ball carry, a 1,000 m row, kettlebell swings to overhead, a 1,000 m SkiErg, dumbbell farmers lunges, a 2,000 m bike, burpee broad jumps and the final sprint. Athletes race solo, as buddies who split the station work, or in a relay team, in women's, men's, mixed and heavier 'Heavy' categories. The average finish time is about 1 hour 20 minutes and there is no cut-off time. The buddy category is the organiser's suggested entry point for newer athletes.

Nuclear Fit is an outdoor hybrid fitness race run by Nuclear Races at its obstacle course site near Brentwood, Essex. Instead of an indoor track, athletes run six 1 km trail loops, each including two 4 ft hurdles, and complete a fitness station after each loop in a central arena called The Core.

The stations use farm-themed equipment: a tyre flip, a farmers urn hug, a plough pull, a milk churn carry, a sandbag duck-and-throw and a squat-and-lift, with separate loads for men and women. Categories include singles, doubles and mixed doubles, plus a three-person relay in which each member completes two runs and two stations, and a Pro wave with longer station distances. Waves start every 10 minutes, chip timing records each run and station split, and there is a 2-hour time limit. It suits runners and gym-goers who want a hybrid race on trails rather than indoors.
