Nuclear Fit vs THE ROX: distancia, estaciones, precio y dificultad comparados (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.

THE ROX is a hybrid fitness event held inside a shopping centre, the A10 Center in Wildau just outside Berlin. It was founded and is hosted by Andy Hagedorn, a personal trainer from the Berlin-Brandenburg fitness community.

The format combines running laps with functional workout stations such as burpee broad jumps, lunges and navy shuttle runs, with judges checking movement standards and electronic timing. Races start in timed slots throughout the day: single runs for women and men, mixed doubles, women's and men's doubles, a mixed team of four (two women, two men), and a kids' run for ages 8 to 14. The organiser says a basic level of fitness is enough and participants set their own pace, so it is aimed at newcomers as well as regular athletes. The shopping-centre setting means racing takes place in front of mall visitors, with partner stands and a warm-up area on site.
