- I had registered as a volunteer for Haarlemmermeer. Do I need to re-register for the new date?
- My question is not listed here. What do I do now?
- Can I participate, without a care, in Mud Masters Biddinghuizen 2020?
- Is teamwork allowed on the Mud Masters course in Biddinghuizen at less than 1.5 meters’ distance?
- What will be different at Mud Masters Biddinghuizen 2020, compared to previous events?
- Still have questions?
