September 23 & 24, 2017 New course - new obstacles - new finish shirt!


We are currently hard at work on plans for the course! Come back to this page later but, in the meantime, check out last year’s map below for a teaser.

6km track 18km track (1 lap)
12km track 42km track (1x18m + 2x12km)


You can choose for a track of 6, 12, 18 or 42 kilometres.

On the 6, 12 and 18 km track you will finish one single round. The 42 km track is built up from one round of 18 km, followed by two rounds of 12 km. The location of the event and the surrounding area determine the composition of the course and the type of obstacles you will face. This turns all editions in Haarlemmermeer, Weeze and Biddinghuizen into totally unique experiences and makes it fun to participate multiple times.

Mud Masters Experience

On our obstacle course you will run, climb, slide, crawl and fly with your Mud Buddies! Check out the video for a sneak preview of our obstacles from the eyes of a Mud Master.


The atmosphere on the event grounds and the obstacles on the course in Biddinghuizen are so great! For that, I fly in specially from Russia.
