Nuclear Fit vs Savage Race: 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.

Savage Race is an American obstacle race series with events currently listed in Florida (Dade City) and Georgia (Dallas), held in spring and autumn. It has received awards from Mud Run Guide and OCR Buddy, including best North American series.

There are two formats. The full Savage Race covers 5 to 7 miles with 25 or more obstacles, including its signature near-vertical slide Colossus, ice baths, fire and mud. Savage Blitz is a shorter option of 3+ miles with 15 to 20 obstacles. Entry includes chip timing, a T-shirt and a medal. Most runners join open heats, while the SavagePRO wave on Saturday mornings competes for overall and age-group awards; there is also a SavageJR race for children and a team option. Runners who complete two or more events in a calendar year qualify for the Savage Syndicate medal. The Blitz suits first-timers, while the full race suits runners with a solid fitness base.
