The Aspen Backcountry Marathons will return on August 2, 2025 and now includes a 50 Kilometer distance to compliment the marathon and "heavy half" marathon! After not hosting the event in 2024, the race will now be produced by Aravaipa Running and will continue to be hosted next to the Duck Derby fundraising event held annually by the Rotary Club Aspen.
We're extremely excited to be able to host this race and revive the backcountry marathons for the local Colorado community and hope to see you in Aspen!
