Nuclear Races 12k Obstacle Course

Double the distance, double the challenge. Test your limits on the full 12km course and every world-class obstacle. Taking you deep into muddy farmland, woodland and lakes on the imposing terrain of the Secret Nuclear Bunker Estate in Essex, the 12km races offers over 70 obstacles and a true endurance feel for those ready to push their limits.

With chip‑timing, high‑quality, achievable natural and man‑made obstacles and no penalty system (you can attempt as many or as few obstacles as you like), it’s built for both seasoned racers and adventurous newcomers alike.
