Event overview

The one you need to train for – take it for granted and it’ll bite you.

It’s the last event of the season on the permanent site. Don’t moan about the cold, wet, wind or mud – cuts, bruises, scrapes and sores are all abundant, but all part of the survivor experience.

If you’re a newbie, small group, big team, veteran or competitive obstacle racer Nuclear courses are thoughtfully designed to be challenging, fun and achievable for all ages and every fitness ability.

Expect a wide range of natural and man-made obstacles over undulating farmland, in woodland, lakes, bogs and through our award winning #lovemud – duck-taping your trainers on isn’t a bad idea!

The Deathslide is included in both courses, but don’t expect a Nuclear course layout or obstacle combination to ever be the same.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
