GYMRACE vs Terrain Race : 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.

Terrain Race is an obstacle and mud 5K produced by EventLab, a US company that also runs fun-run brands such as Bubble Run, Muddy Dash and Blacklight Run. The current event is Terrain Race Irvine, held at Oak Canyon Park in the Silverado area of Orange County, California.

The course is about 3 miles (5 km) of rugged terrain with climbs, crawls, walls, ropes, monkey bars and mud pits. Participants pick a start time and run in waves with friends; a VIP package adds a priority wave start and extra merchandise. Packet pickup is offered the day before the race. The format is aimed at recreational runners, groups and first-time obstacle racers looking for a muddy, single-distance event rather than an elite competition.
