Mud Tribe

Gather your tribe! Join the fun at Mud Tribe, a 5km muddy obstacle course run that’s suitable for all abilities. Designed with fun in mind, this is the perfect event for those looking to get muddy and enjoy the experience, and with a 1.5km option available, it’s great for families too! Get ready for a day of mud, foam and laughs as you navigate the obstacle course, create unforgettable memories and maybe even raise money for a good cause.

Mud Tribe - 1.5K

For our families with younger children, the shorter 1.5km option of Mud Tribe means even the youngest family members can join in: you’ll get the mud, foam and fun!

It is a great option for those who don’t want to take on the full 5km course. The course features obstacles that all can achieve, whatever their age.
