About the race
Nuclear Rush is a muddy obstacle course event held at the Secret Nuclear Bunker estate in Kelvedon Hatch, Brentwood, Essex. The event runs a range of race formats for adults, families and children across farmland, woodlands, rivers and lakes. Adult races are open to participants aged 13 and over; 13–15 year olds require adult accompaniment and under 16s must be accompanied by a paying adult.
Race features include permanent, mixed natural and man‑made obstacles, chip timing and a finishers medal. On‑site amenities include hot washdowns, changing facilities, buoyancy aids for water obstacles, a free car park, free finishers photos and a free bag drop. An event village provides spectator areas with food, music and merchandise.
Signature obstacles named on the course include the 20 foot Deathslide, the Travelator and a multi‑lane zip wire into water; para‑plunge style zip lines are also part of the course. The children’s programme offers shorter Rookie and Family distances with age‑specific formats and a Rookie Pro category where obstacles are mandatory and carry a burpee penalty if not completed.
