Nuclear Races

Channel your inner mud-lover at Muddy Mayhem this October!

Muddy Mayhem is back this October!

This messy, mud-mad event includes a 5km mud run at the well-known Nuclear Races venue in Brentwood. Many of the Nuclear Races renowned obstacles will be included in the 5K route, such as the Zip Wire and Deathslide! There are 40 obstacles in total to challenge your inner mud-lover – are you ready to take on the challenge?!

Join us on the day from 10.15am, with the race setting off at 11am. Before you get set and go, there will also be a fun warm-up to get you ready for the muddy mayhem ahead!

We recommend wearing comfortable trainers and old clothes or gym clothes that you don’t mind getting muddy and wet – with a fresh change of warm clothes and shoes, of course! And please – leave the lovely jewellery at home. Fortunately, there are toilets, showers and changing rooms on site so you don’t have to cake the car in mud on your way home!

Love mud but not sure about the obstacles? Fear not! You can skip any obstacle you’re not sure on – we won’t throw mud pies, promise!
