Mud Mash X – May 19 is a 10 mile obstacle and run course designed to push you to the limits of emotional and physical endurance. Designed by active duty Navy SEALs and adventure race professionals, we challenge participants with over 25 obstacles and insane hill climbs through rolling hills and heritage oaks of the authentic California west.

Mud Mash – May 19 and Oct 27-28 Tougher than the tough ones, and more fun than the fun ones: the All Out Way!  The Mud Mash is a 5k and 10k mud run with dirty obstacles, wall climbs, lake scramble, hay bales, slip and slide and of course a huge, nasty mud pit. Not to mention some tough trails that will be even tougher when you’re wet and MUDDY. 

And we’re adding a second day to our fall Mud Mash! 

We’ve outgrown the capacity of the park and that means more choice in when you get yourself to beautiful SLO, more team opportunities, and . . . in it to win it? Two chances at the top prizes!
