Way back in April, we brought you news of the ultimate Race for Racers: the Nuclear Challenge Cup.

As the name suggests, this will be run at Nuclear races by James Parrish. But do we really need another competitive championship race? James thinks we do:

"I want to drive the sport forward and create something for everyone. The Challenge Cup is designed to cater for the next stage of people's journeys; for those aspiring to take part in a competitive yet fair race in their age category, and for those competing at the top of the sport. Above all, I want to make it fair by adjudicating it, and to set a standard for other races to follow."

The challenge, to be held on the 11th November, is fast approaching. You may remember that James invited constructive discussion on how the event should be run. Well, we’re here to tell you that the rulebook is IN.

Over the next few weeks, we shall be bringing you pre-race news, previews and maybe even some instructional videos for the more challenging obstacles.

So! Without further ado, let us present the Nuclear Challenge Cup Official Rules:

The Race:

Entrants must be aged 17 or over.

There will not be an official warm up, but there will be heated tents for independent pre-race warm up.

The race will be chip timed.

To ensure fairness, independent adjudicators will man all the signature obstacles, which must be genuinely attempted once and only once. If failed, a penalty loop has to be completed. Any non-genuine attempts may incur a time penalty.

80% of the obstacles on course are mandatory completion. These will be marked with an M and are 100% achievable. Multiple attempts will be allowed.

The remaining 20% of obstacles are the more technical obstacles, where failure will incur a penalty. These obstacles will be filmed. A penalty loop is applied when a genuine attempt at an obstacle has failed. A penalty loop is designed to take 3-4 times longer to complete than the obstacle and work the same muscle groups. Penalty loops may increase the distance of the course, and will have their own marshals to ensure full compliance.

Nuclear reserve the right to shorten the distance of, or reduce the weight of carries in penalty loops for female racers.

Step and help-ups are allowed on certain obstacles, and are dependent on the runner’s size. Obstacles are there to test upper body strength, not a participant’s ability to reach them.

The amount of mud and water will be limited to ensure the obstacles are as achievable as possible. Sawdust will be available where appropriate.

Competitors should expect an obstacle heavy course rather than a trail run.

Obstacles must completed as directed by marshals.

Runners must stay within the marked course at all times.

Complaints about fairness and/or unsportsmanlike conduct are to be made 15 minutes of race completion. RD decision is final. Each racer at the end of the course shall sign a declaration of sportsmanship.

All competitors are to have their names in 2” clear lettering on the back of their race tops, and this must be visible at all times during the race. Nuclear can provide a branded technical personalised tee on sign up for £10. No name, no race! To this end, there will be no race bibs or numbers.

The course will accessible the day before the race between 11.00 and 4.00 for inspection and practice in groups of two or more. The course risk assessment will also be available for inspection.

We will be there to cover the race. In order to ensure full coverage of both the male and female races, the Ladies’ wave will begin ten minutes after the Men’s wave.
