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

METRIX is a fitness competition for pairs that combines a workout with nightclub-style production: DJ sets, lighting and a social recovery area with ice baths and saunas. It was co-founded by Toby Spooner and Will McLaren, launched in 2025, and has held events in London, Manchester and Cardiff.

Pairs move through five stations: SkiErg, burpees, rowing erg, bike erg, and sleds with shuttles. They share the workload however they like. Event listings describe each station as a ten-minute block. Scoring is done by technology rather than judges, with live tracking of every metre and rep, and a prize pool for the top teams. METRIX uses simple movements and is aimed at everyday athletes and first-timers, while still giving fitter pairs a competitive target.

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.
