Do you love action, adventure, and a good dose of mud?
Then MudGrunn is the challenge for you! On Sunday, September 21st, we challenge you to push your limits on a course full of obstacles testing your strength, endurance, and perseverance.
What can you expect?
Our route takes you through water, sand, and challenging terrain. You will climb over walls, crawl through nets, plow through deep mud, and crawl under obstacles. Jump over ditches, conquer slippery slopes, and show that you can handle the rugged Groningen landscape.
MudGrunn is not just a run; it is an experience. You not only fight the course but also yourself. Together with your team or solo, you will battle the mud and work your way to the finish, where pride and satisfaction await you.

Who is MudGrunn for?
Whether you are a seasoned mud runner or just looking for a sporty challenge, MudGrunn is for everyone who dares! Choose your own pace, help each other, and enjoy an unforgettable day full of action and spectacle.
