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.

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

  7. Receive a Nuclear Fallout survivor medal & finisher top

This event will comply with local authority COVID-19 guidelines so we can deliver  the safest experience for our racing #nuclearfamily:

  • Every racer will be temperature checked inside their vehicle on arrival.
  • Face coverings must be worn from vehicle/carpark to registration/check-in through to the briefing, warm-up, start and finish. A face-covering must be carried in a water proof bag or pouch for the duration of the race – to be used if the 2m distancing rules cannot be obtained at or near obstacles. A face covering will be given to every racer as they cross the finish line and must be worn immediately. There are no exceptions to this rule. There are no exemptions for not wearing a face covering whether it be medical or any other reason.
  • Groups of up to 30 people up to 2-3 metres socially distanced will be allowed in any one area.
  • Expect a rolling, staggered start which may not adhere to your published time.
  • Social distancing systems, touchless check-in, temperature checking, track & trace and wave/group sizes of 5 people released every few minutes.
  • Obstacle sanitisation in operation,
  • Racers must use the full width of every obstacle & keep apart at all times. Team-work is not permitted.
  • Expect the usual big variety & quality Nuclear obstacles as well as rigs & multi touch obstacles, but with continuous obstacle sanitisation in operation.

The car-park will be located right next to the event village to allow for easier & quicker arrival & exit once finished.
