Blue Sky Trail Marathon

Join us for the 19th running of the Blue Sky Trail Marathon! Taking place on the trails between Horsetooth Mountain Park and the Devil’s Backbone Open Space, the course takes you on a north-south tour of the easternmost hogbacks of Northern Colorado’s mighty Front Range Mountains. With a moderate amount of elevation gain/loss, the route offers a little bit of something for everyone.
The course is designed to appeal to both veteran trail runners and those looking to experience their first trail racing adventure. The terrain is 100% dirt and 90% sweet Colorado singletrack. The generous overall cut-offs should ensure a successful day for everyone.
After the race, kick back and enjoy the always-popular BBQ and generous sponsor giveaways.
