Dirty Dozen obstacle races, mud run, and OCR information, distance, cost, dates, calendar, discounts, obstacles, reviews, and more
Each course is planned and designed by ex-British Special Forces to combine our military style obstacles and it takes the following to build one of our obstacle courses:
– 3 weeks to build
– over a week to take down
– 4 days to mark out the course
– Over 100 volunteers
– A huge build team
– Big excavation machinery
– An extensive medical team
– Multiple life guard teams
Our goal is simple, put on great events at great prices and ensure they are exciting but also safe.
After years of competitive sport and seeing the rise of obstacle course events, we knew this was a sport we wanted to get into. Not content with participating, we wanted to see how far we could take obstacles courses so we decided to design and build our own obstacles races. 2013 was a great year for us, it saw the launch of our first event to which we received some great reviews.
We have put months of research into planning our events and combined with the fact that our obstacles and courses are designed by ex-British Special Forces means Dirty Dozen Races are in a league of our own. Our obstacles constantly evolving and the Dirty Dozen Races Obstacle Test Centre is full of prototypes that have seen a lot of action. Each course is meticulously planned on foot and we have a real talent for hunting out great terrain.

Dirty dozen 18th April 2015
Weer can we find the results ??? nr 3537 Van Heirzeele Marc 50+
Repeat offender- I'll be back
Dirty dozen was my first OCR in October 2013, since I have done many others but none have matched it. I have been to every Dirty Dozen event and will continue to do so for many reasons.
To start, the whole event is well organised and the obstacles put together well. This is very important whether, it is at the bag drop, on top of a 12 ft wall, or when swimming through a ice cold lake. It is nice to know that the obstacle won't break and that there are well trained life guards around.
But, most importantly, the event provides enough of a challenge whilst not giving into gimmicks. So there are no electric shocks or other such horrible obstacles; just big obstacles that will leave you with a sense of accomplishment.
My sentiment is shared with the whole Dirty Dozen community (and there is a lot of us now) who can be seen with the coveted bobble hat.
