Nuclear Fit
Nuclear Fit is an outdoor functional fitness race held at the Secret Nuclear Bunker in Kelvedon Hatch, Brentwood, Essex. The format pairs six 1 km trail running loops with sequential workout stations that combine endurance and strength tasks. Events run across dates in May, July and September and include Individual, Doubles, Relay and Pro categories, with adult events listed as 16+.
Stations and exercises described for the course include tyre flips, plough pulls (sled), milk churn carries, farmer urn carries, repeated throws and runs with a weighted bag, and timed squat-and-lift repetitions. Workloads and distances vary by category; some Pro stations have longer distances or higher rep targets.
Race-day services include chip timing with split breakdowns for each run and station, trophies for top male and female finishers, a finishers medal, official photos, and free spectator access with on-site parking. Training sessions and league or team entry options are available ahead of events. The central event village features music, stalls and sports massage facilities, and the organisers provide marshals and timed results for detailed performance feedback.
