From the Organizer

The 14th annual Mudslide is a mudrun that's FUN. Yes, you'll get muddy, yes there is running, yes there are 15 obstacles but NO fire, NO barbed wire, and NO electric shocks! The 4.2 mile and 6.0 mile courses both start at the top of Morning Star with access from the Yodeler lift and run along the ridgeline to Spruce Lake and then back around the mountain to Eagle where the short course and long course split.  The short course heads down the hill, where the long course adds a bit of uphill running just in case you're feeling especially tough. 

Kids course is for kids 10 & under, kids under 10 may run the short course but must be accompanied by a parent or guardian.

If you’re feeling fast and think you could place in the top 10, please start early in your wave, but all runners will be timed and awarded a finisher’s medal.

If you are in the long course and miss the start window you will have to switch to the short course.
