Nuclear Fallout is a winter obstacle race at Kelvedon Hatch near Brentwood, taking competitors across muddy farmland, woodland, rivers and lakes. The permanent Nuclear Races course combines challenging natural terrain with a packed collection of purpose built obstacles.
Racers can choose between the 6K and 12K challenges, with the longer distance stepping up the difficulty across a lapped course. Expect mud, water and demanding terrain between obstacles, alongside Nuclear's signature features designed to test strength, agility and determination throughout the race.
Both distances are chip timed and cater for everyone from first time obstacle racers to experienced competitors looking for a tougher winter challenge. The event village provides a base for runners and spectators, with food, drinks and facilities available around the course.
