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

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.

TRYKA is a hybrid fitness race league based in Dublin, which describes itself as Ireland's first inclusive hybrid fitness race league. Events are held in a season of races that count towards the TRYKA Finals, with Series 2 visiting the RDS in Dublin and the NEC in Birmingham.

The standard race is 8 x 800 m runs, each followed by a functional workout: SkiErg, farmers carry, ram thrusters, sled push, sled pull, rower, walking lunges and burpee broad jumps, ending with a 40 m sprint finish. The TRYKA 500 is a half-distance version with 500 m runs and modified workouts for first-timers. Other divisions are Open (800), Pro with heavier weights, Doubles (men, women, mixed), four-person Relay, junior doubles for ages 8 to 15, and the TRYKA Clan for two adults with two children. The league suits beginners through to experienced hybrid racers, gyms and company teams.
