Event information

Calling all challenge and adventure enthusiasts!

Join us on Sunday 11th May at Nuclear Races in Kelvedon Hatch, Brentwood, for an exhilarating experience, conquering thrilling obstacles while supporting local people facing incurable illness and bereavement

This multi-award winning 6k and 12km course distance is set over obstacle-loaded, muddy farmland set in the heart of the Secret Bunker Estate, Essex. 

Nuclear is well known for delivering award-winning events with big, high quality, achievable, natural and man-made obstacles designed to test every ability of fitness on fast-paced courses over epic varied terrain.  Expect the infamous deathslides, para-plunge zip lines and new swing-a-ding obstacles at the lake zone plus loads of other obstacles. 

• Course distances are 6km & 12km. This event is NOT a lap race.
• All racers are chip-timed.
• Your wave will be made up of 6 & 12k runners. You will run together until 6k where 12k runners will split. There will be warning signs, arrows and a Nuclear marshal at the split to guide you.
• There are 70+ obstacles on the 12k, 40+ on the 6k courses.
• Attempt as many or as few obstacles as you like – it’s your challenge!
• There are no penalties.
• A Nuclear Rush survivor medal & finisher top plus hot cup of tea at the finish.
• Option to de-select finisher top at checkout, reducing our impact on the environment & reducing your final checkout total.
