What Are Nuclear Events

Nuclear Events are thrilling obstacle races held on permanent farmland, featuring a mix of mud, woods, rivers, lakes, and fields. These events offer a variety of obstacles, including the 20-foot free-fall Deathslide, a 15-lane zip-wire into the water, and the 120-meter permanent steel Gorilla Bars. 

Participants can also explore a four-story deep underground Secret Nuclear Bunker. Nuclear Events cater to all ages and skill levels, with Rookie Races for children aged 4-14 and a competitive British OCR Championship for athletes. Whether you’re a newcomer or a seasoned racer, Nuclear Events promises a memorable and muddy experience!
