Nuclear Rush

Nuclear Rush

Nuclear Rush is a muddy obstacle course event held at the Secret Nuclear Bunker Estate in Kelvedon Hatch, Brentwood, Essex. The event offers adult, family and children race categories across short and longer course formats.

Adult options include a 6 km course with more than 40 obstacles and a 12 km course with more than 70 obstacles. Courses run through farmland, woodland and lake zones and include natural and man‑made obstacles. Chip timing and a finishers medal are provided. Participants can choose to skip obstacles without penalty. The site provides hot washdowns, changing facilities and buoyancy aids for water obstacles. Free car parking, free bag drop and free finishers photos are included.

Children and family categories run shorter laps and focus on age‑appropriate obstacles, mud, water, climbing and crawling. Age rules vary by category; some younger participants must be accompanied by a paying adult. Rookie and family races award medals and use chip timing.

The course features named signature obstacles such as the Deathslide and para‑plunge zip lines, plus other permanent obstacles including a travelator and a multi‑lane zip into water. The venue includes an event village where spectators can watch the action and access food, drinks and merchandise. Visit the organization's website for the most recent information.
