Blue Sky Marathon & Half: October 17-18, 2026 – Gnar Runners

The Blue Sky courses take you on a north-south tour of the easternmost hogbacks of Northern Colorado’s Front Range mountains. With a moderate amount of elevation gain and loss and a variety of terrain, 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 cut-offs should ensure a successful day for everyone.
