HYROX PFT vs Nuclear Fit: distancia, estaciones, precio y dificultad comparados (2026-27)

The HYROX Physical Fitness Test (P'F'T) is a short benchmark workout designed by HYROX to introduce people to the sport and show which race division suits them. It runs during the HYROX gym tour, when HYROX sets up mini events at gyms, and it is also used as a stand-alone training test.

The workout is a 1,000 m run (outdoors or on a treadmill at 2% incline), 50 burpee broad jumps, 100 stationary lunges, a 1,000 m row, 30 hand-release push-ups and 100 wall balls (6 kg men, 4 kg women). HYROX uses the finishing time as a guide: 15-25 minutes points to the Pro division, 25-35 minutes to Singles and 30-45 minutes to Doubles. There are no sleds or heavy carries, so it suits newcomers checking whether they are ready for a first full HYROX race.

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.
