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

Gladiator Race is a Czech obstacle course race series organised by Sportvisio, z.s., an events organisation based in Hradec Králové that also runs road and trail races. The series visits venues around the Czech Republic, including Prague, Pardubice, Terezín Fortress and Český ráj, and adds seasonal editions such as a Halloween race at Josefov Fortress and a winter 'Taxis' race in Pardubice.

Courses run through natural terrain with water, mud and built obstacles. Events such as the Halloween race offer a competitive RACE category, an OPEN category and a FUN option, with entries for individuals, mixed pairs and teams, plus children's races (Kids I, Kids II and Family). Some events have special formats, such as the Halloween race where costumes are encouraged. Series awards such as Triumphalis and Primus Palus recognise racers who complete multiple events. The series suits both first-time obstacle runners in the open categories and competitive athletes in the RACE waves.

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.
