Nuclear Rush Weekend

Date & Location

Kelvedon Hatch, Essex

Organiser’s Description

Choose from Nuclear Rush 7k or 12k distances over our ultra-gritty, properly muddy, obstacle-loaded, fast-paced, punishing course, designed to challenge and test every ability of fitness over epic terrain set in the heart of the Secret Bunker Estate. And new for 2017 - Nuclear Oblivion EXTREME! Designed to challenge the fastest and fittest obstacle race athletes out there, it’s our most brutal and unforgiving event in the Nuclear calendar. There’s 8.5 hours to complete as many 12k laps of the Nuclear Rush course as you can, tackling 90+ man-made and natural obstacles per lap. Oblivion has the potential to be a 60k+/450+ obstacle challenge! 13/14 May.
