Race Information
Taking place on the trails between Horsetooth Mountain Park and the Devilβs Backbone Open Space, the course takes you on a north-south tour of the easternmost hogbacks of Northern Coloradoβs mighty Front Range. With 3,500 feet of elevation gain and an equal amount of elevation loss, the route offers a little bit of something for everyone. It is designed to appeal to both veteran trail runners and those looking to experience their first trail racing adventure.
The course is 100% dirt and 90% sweet Colorado singletrack. The terrain ranges in difficulty from smooth dirt trail to technical rock gardens.
