Course Description:

Riverside State Park ORV area is about 600 acres with a mixture of hills, muddy areas, and single track trails winding through the ponderosa pine forest. This area has plenty of hilly terrain without being too difficult. Along the course you'll find around 20 obstacles & mud pits that will challenge you along the entire 3 mile course.

Aid Stations:

There are aid stations at each mile of the course. Mile 1 and 2 have water only while the Finish Line station has water, fruit & a quick snack. Medics will be stationed at the finish line, along with roaming around the course as needed.


This event is non competitive and not timed. You are only racing against yourself & your teammates for bragging rights!


Spectators are free to come out and roam the course. But please stay clear of each obstacle & off the runner's path.


All cars entering the State Park will need to have the Washington State Discover Pass. Annual passes can be purchased before hand, or a day pass can be purchased on site.

Post Party:

There is no post-party because our event is the party! Food vendors will be onsite during the day.


A FREE bag check is available to each participant. Along with free showers & changing tents.


You're welcome to sign up as an individual, but we always say ""The More, The Merrier"", so create a team and invite all your closest friends & family. Heck... invite your archenemy too! Then you can push them face first into the closest mud pit.
