Aspen Backcountry Marathon
Utilizing the beautiful trails that surround Aspen, offering two options, a full or heavy half-marathon, both run almost exclusively on dirt trails. The diversity of terrain, challenging ascents & descents and overall elevation gain will challenge even the most well-trained athletes. With spectacular views of the Elk Mountains above and the city of Aspen below, this is one race you’ll be sure to remember!
This race will be a limited support race. There will be aid stations, portable toilets at the start/finish, volunteer crews, and timers. There is volunteer medical personnel along the course and at aid stations, but there is no guarantee of rescue or medical attention. Each participant is ultimately responsible for their own rescue and preparation for course and weather conditions.

Aspen Backcountry Marathon Safety Plan. This race will be a limited support race. There will be 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.
