Aspen Backcountry 21K Course Info

New Direction for 2017!

We will be running 2016's course in reverse. Utilizing the beautiful trails that surround Aspen, this 21K course is run mostly on dirt trails and has over 2,500' of elevation gain. The diversity of terrain, challenging ascents & descents and overall elevation gain will challenge 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 food and water stations, portable toilets at the start/finish, volunteer crews, timers, and mile markers. There are 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.
