THE BIG ONE

Choose from multi award winning 6km or 12km course distances over obstacle-loaded, muddy farmland set in the heart of the Secret Bunker Estate, Essex.

Nuclear is well known for delivering UK’s most award winning events with big, high quality, achievable, natural & 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 & new Swing A Ding obstacles at the lake zone plus loads of other obstacles.

RUSH RACE FORMAT
  1. The course distances are 6km & 12k. This event is NOT a lap race.
  2. All racers are chip-timed.
  3. Your wave will be made up of 6 & 12k runners. You will run together until 6k where 12k runners will split. There’ll be warning signs, arrows and a Nuclear marshal at the split to guide you.
  4. There are 70+ obstacles on the 12k, 40+ on the 6k courses.
  5. Attempt as many or as few obstacles as you like – it’s your challenge!
  6. There are no penalties.
  7. A Nuclear Rush survivor medal & finisher top plus hot cup of tea at the finish.
  8. Option to de-select finisher top at checkout, reducing our impact on the environment & reducing your final checkout total.
  9. We will start clearing the 6 & 12k Rush courses from 5pm onwards (last runner 1st).
