Mud Masters

A challenging obstacle course, based on military obstacle courses!


You’ll escape the daily grind on our physically and mentally challenging course and – together with your friends – you’ll conquer the most spectacular obstacles. For one day, you will be the action hero you always wanted to be.

The difference distances of 6, 12, 18 and 42 kilometers, make it a realistic challenge for many people. At Mud Masters Obstacle Run, a fast finish time is not important; it’s all about making it to the finish line together. And when that happens, it is time to celebrate that accomplishment with a well-deserved finish beer. Work hard, play hard!

60.000 Mud Masters a year since 2012!

On October 6th, 2012, we organized our first event for 4.000 participants in Haarlemmermeer. With that, we put obstacle running on the map as a new sport in the Netherlands. Since then, over 60.000 Mud Masters finish every year on our spectacular festival grounds in Haarlemmermeer (NL), in Biddinghuizen (NL) and on Airport Weeze (GER). The variety in locations, and the fact that we are constantly working on new and more spectacular obstacles, make sure that every edition is a completely new experience!


“A well-organized, world-class event!”
