Mud Masters Family Edition - Haarlemmermeer

About the race

Mud Masters Family Edition Haarlemmermeer is the family-focused obstacle run on the Mud Masters site at Stelling 1 in Vijfhuizen. On Sunday 14 June 2026, the 3 km and 5 km Family Edition distances take centre stage within the wider Mud Masters weekend. The course is about mud, obstacles, teamwork and fun, without requiring participants to take on the longest Mud Masters distances straight away. Children can head onto the course together with adults, making the event suitable for families, groups of friends and obstacle-running beginners. The festival setting, finish experience and recognisable Mud Masters obstacles make it an accessible entry into the same muddy atmosphere as the wider weekend.
