Aspen Backcountry

Join us for the Aspen Backcountry event on August 1, 2026, featuring a 50 Kilometer race alongside the marathon and "heavy half" marathon, set against the picturesque backdrop of Aspen. Held in conjunction with the annual Duck Derby fundraising event by the Rotary Club Aspen, this race is a highlight for the local Colorado community. Participants are reminded to acquire a CORSAR card from Colorado Outdoor Recreation Search and Rescue (CORSAR) for race day registration. Showcasing the beauty of the backcountry, this event promises an unforgettable experience for all runners. See you in Aspen for a day of outdoor adventure and friendly competition!
