Course Description:

Choose from 7km or 12km course distances over ultra-gritty, properly muddy, obstacle-loaded farmland set in the heart of the Secret Bunker Estate, Essex.
Your wave will be made up of 7 & 12k runners. You will run together until 7k where 12k runners will split. There’ll be warning signs, arrows and a Nuclear marshal at the split to guide you.
There are 90+ obstacles on the 12k, 50+ on the 7k courses. Attempt as many or as few obstacles as you like – it’s your challenge! There are no penalties.
We will start clearing the 7 & 12k Rush courses from 5pm onwards (last runner 1st).

For SUnday only: After trialling different formats this year we are excited to continue with Nuclear’s THREE PERSON RELAY EVENT at Nuclear Rush Weekend 2020! Nuclear THREE is a team (3 members only) event designed to test teamwork abilities & have fun.
This is the race where you start & finish together as a team. The team nominates a particular member to undertake each obstacle successfully & change the bib accordingly. The person + bib can be changed as many times as required in order to successfully move on as a team. There are three categories – men, women, mixed men/women & approximately 10 EXTRA NUCLEAR3 TEAM obstacles which require all three team members to work together to succeed. The event shares routes & obstacles on the 7k Nuclear Rush course.
The last team chip to cross the finish line will give the team time, racers must finish together. The courses will be cleared & closed from 5.30pm onwards (last runner 1st)

Kids Race: Nuclear Rookies are fun, pumped-up muddy obstacle courses for 4-14 year old kids of any fitness level
Rookies can test their skills on a specially designed fun 1.5/3km course filled with around 20 kid’s sized & guaranteed Nuclear M.U.D! Rookies will climb in & out of the muddiest ditches, scrabble under cargo nets, crawl through tyre tunnels, over ramps, walls & monkey-bars as well as running in woods, on paths & open fields.
Rookies 4-8 years of age complete one lap of the 1.5km course. 9-14 year old Rookies complete the 1.5km lap twice (3km). A grown-up of 4-7 year old’s must accompany their child on the course (free of charge & registered at time of booking). Older (9yrs+) & younger children (4-8yrs) can now race in the same wave together.
ETIQUETTE: Float alongside & step in with help over obstacles if the child needs it, but stepping back from the course, so it’s clear for other participants.
THE VIBE: There’s no pressure to complete the obstacles – we want Rookie obstacle racers to grow in confidence from their experience. Team-work is actively encouraged at Nuclear, it’s not all about winning; helping each other achieve is just as important. Every Rookie has the opportunity to download a personalised Rookie certificate post-race.


There are no official teams, you can race indivdually or as a team (10 or more receive a discount). Sign up using the team option at time of booking.
