Nuclear Fit Pro

Nuclear Fit Pro is a timed pro category held at the Secret Nuclear Bunker in Brentwood, Essex. The format alternates a 1 km trail run with a functional fitness station, repeated six times for a total of 6 km of running and six workout segments. Stations include tyre flips, plough pulls, milk churn carries, duck and throw, squat and lift sets, sled pulls and other strength carries, with longer station distances on stations 1, 3, 5 and 6.

The category uses mandatory fitness stations and full chip timing with split breakdowns for each run and workout station. Equipment and event features noted for the Pro category include timing chips, 2 x 4 ft hurdles, a finisher medal for all competitors and trophies for first, second and third places. Individual, Doubles and Relay entry options are listed for Nuclear Fit, and the Pro category is presented alongside other seasonal dates in May, July and September.

Event-day facilities and atmosphere include a central arena with music, marshals, sports massage stations, a variety of stalls, free on-site parking and free spectator access. Training sessions are available at other times of year for participants wanting practice on the format and stations. Visit the organization's website for the most recent information.
