No first or last place, everyone wins!

"The Funnest" 5k Obstacle Run!

Mud Factor is the misfit of mud runs, no keeping score, no first or last place, just thousands of MF'ers out playing in the mud! Organize your team and represent at this Seriously Fun, 5k Obstacle Run! Premier venues, bad ass obstacles, kick ass music and more.

Experience your first Mud Factor

Mud Factor Isn't a Race or Competition.

Mud Factor was created to offer a "Seriously Fun!" alternative to the "tough guy" mud runs. We measure our success by how much fun our participants have, not how intimidating the course is. The Mud Factor experience is not about how fast you run, it's about celebrating that you took on this challenge... and finished!

It aint no fun, if the homies can't Mud run!

Drag Your Friends Through the Mud!

Mud Factor is all about fun, friends and family. The Mud Factor experience is incomplete without making shared memories with the people who mean the most to you. We encourage you to get your friends and family together for your first Mud Factor Seriously Fun, 5k Obstacle Run!

Dress Up & Get Down!

Stand out from the crowd with costumes, themes or uniforms! Ninjas, pirates, tutus and pigs in wigs are all welcome at Mud Factor. Any team dressed as The Goonies must do the truffle shuffle before being admitted to the event. And if your team comes as The Avengers, please no Hulk smash.

Create a Mud Factor team for you and your friends!

Seriously Fun, Family Obstacle Run!

NEW! Family Waves

Ages 4 & Up

Same Obstacles


Bring the Whole Family!

The first waves of the day are exclusive to MF KIDZ participants and is an opportunity for your child to conquer Mud Factor, just like Mom and Dad. The addition of the Mud Factor “Family Wave” option now allows for parents or guardian to run with their children and participate on the obstacles and climb through the mud together as a group.

MF Kidz + Family runners will experience the same “Seriously Fun, Mud & Obstacle Run,” only in a shortened version and fast forwarding to the good parts! The course will be approximately 1.5 to 2 miles in length. Along with the same big smiles, MF Kidz will be shown the same respect – “Skully” tattoo and bandana before the run, and the same achievement medal as the adult waves when they cross the finish line.
