Blue Sky Trail Marathon route

From the organizer

Organizer's website

Welcome to the 11th running of the Blue Sky Marathon, Fort Collins original and only trail marathon. Taking place on the trails between Horsetooth Mountain Park and the Devils Backbone Open Space, the course takes you on a north-south tour of the easternmost hogbacks of Northern Colorados 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 generous nine hour cut-off should ensure a successful day for everyone.
