Fallout is our Nuclear winter beast…

The one you need to train for – take it for granted and it’ll bite you. It’s our last event of the season on our 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 & achievable for all ages & every fitness ability.

Expect a wide range of natural & man-made obstacles over undulating farmland, in woodland, lakes, bogs & 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.


  1. Chiptiming

  2. 7k & 14k (2 x laps of the 7k course) distances. There are no penalties.

  3. Nuclear MC

  4. Limited food & drink, toilets & Nuclear merch shop – it’s your challenge! Attempt as many or as few obstacles as you like

  5. Water stations

  6. Water obstacle depth is no deeper than 4-5’

  7. Receive a Nuclear Fallout survivor medal & finisher top

  8. The Fallout course will be cleared from 3:30pm onwards (last runner 1st) due to failing light levels.
