Get ready for the ultimate
Challenge!
The Colliers Mudathon is back for its 9th year, and this time we’re switching things up with a new venue, new course, and new challenges to take your mud-soaked adventure to the next level.
It’s time to conquer 5 kilometers of pure fun—expect epic runs, heart-pounding climbs, daring swings, and splashy swims, all while getting down and dirty! Known as the property industry’s hardest 5K, it’s not for the faint of heart, but if you’re brave enough to take on the mud and the outdoors, we promise it’ll be a wild ride.
Are you ready to take the plunge?
Let's do this! 💪
The Mudathon brings us a real opportunity to make a difference in communities other than our own. We have supported a wide array of charities which our people have a connection to, giving everyone involved a great sense of achievement and contribution. It is great to look up from our day jobs for a day and commit people to a different cause. Good for our people and the business as a whole.
John Munday | CEO UK
This years Mudathon is located in Brentwood, Essex just 15 minutes from the A12, M25 and M11.
