BACKCOUNTRY MARATHON | SATURDAY, AUGUST 12, 2017 Aspen's most scenic running race...not to be missed.

Utilizing the beautiful trails that surround Aspen, offering two options, a full or 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 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.

1st place Male and Female = $600
2nd place Male and Female = $400
3rd place Male and Female = $200
