If you are looking for a very challenging adventure with some of the most scenic views on earth then this might be the trail race for you! We have run the 32 mile race two years in a row and this is a tough but gorgeous race I would recommend!

This race! Sky, mountains, flowers, boulders, & wildlife for miles. We even saw a moose across a valley! But don’t forget to keep your eyes on the trail b/c it is also the most technical course! Great aid stations, finisher awards, and after party!
