Course Description:

This 5K run features a one-of-a-kind course packed with 18+ outrageous obstacles. Thousands of runners will laugh their way through the route as they slip, slide, jump, climb, and crawl to muddy glory.

There will be aid stations and paramedics on standby. Water and snacks will be available at the start and finish line, along with a water stop on the route.


There are rewards available to people who fundraise certain levels for the National Multiple Sclerosis Society.


No fee for spectators. Spectators have a front-row seat for the Start, Finish, and several signature obstacles.


Free Parking! Some sites have on-site parking and some utilize shuttles. Parking information will be shared one week prior to your event date in both a pre-event information email and on your city page.

Post Party:

The party starts at the finish line! We have food, vendors, a merchandise tent, and a large festival area for teams to celebrate their mucky accomplishments.


There’s a mission behind the muck: 100% of funds raised by MuckFest participants benefit the National MS Society whose mission is to help people affected by MS and ultimately end MS forever.
Age Restrictions: Participants must be at least 10 years of age. Participants who are 10 - 14 must be accompanied by a guardian. Those ages 15 - 17 can be accompanied, but must submit an additional waiver. The free Lil' Muckers area is designed for kids too young to run the MuckFest course.
On average, it takes most participants 45 - 90 minutes to complete the course
We will have lifeguards on obstacles with water over 5 feet deep. If you don't feel comfortable taking on an obstacle, you are welcome to skip it.
There will be public hose-off areas and private changing tents provided for cleaning up
