Nuclear Fit is the ultimate outdoor fitness race designed to test you physically and mentally. This fitness race combines six 1K trail runs with intense workouts and fitness stations, like sled pulls and tyre flips. Don’t like running? Nuclear Fit Storm has all of the fitness stations, with none of the running. It’s a fresh alternative for those looking for a fitness race and to get outdoors. New for 2026 Nuclear Fit Relay.
