Safety Plan

Aspen Backcountry Marathon Safety Plan. This race will be a limited support race. There will be food and water stations, volunteer crews with EMT and First Responder experience. Please do not expect a high level of runner support like other marathons can offer. The logistics of a backcountry race makes additional support very difficult. In addition, we have to be careful about impacting the environment since it is at a high altitude, remote, and on National Forest Service land

Cupless Race

The Aspen Backcountry Marathon and Half Marathon will be CUPLESS COURSES! For hydration, we will be selling (during online registration) a reusable / foldable soft-cup from UltrAspire to use at the aid stations for $6. We recommend participant in addition to the reusable cups, to carry their own hydration system.

*To receieve the KOM prize you must finish the Marathon.
