Aspen Valley Marathton

Set against the breathtaking backdrop of Colorado’s Rocky Mountains, the Aspen Valley Marathon is one of North America’s most scenic destination marathons. The event takes runners on a predominantly downhill journey through the spectacular Roaring Fork Valley, beginning near the historic town of Aspen and finishing in nearby Basalt. Combining mountain vistas, crisp alpine air, and a fast net-downhill profile, the race has become a favorite among runners seeking both stunning scenery and personal-best potential.

The marathon course follows the Rio Grande Trail through the heart of the Roaring Fork Valley, offering expansive views of the surrounding mountains, forests, rivers, and open meadows. Unlike many mountain races that feature punishing climbs, the Aspen Valley Marathon is known for its gentle downhill gradient, making it appealing to runners chasing a Boston Marathon qualifying time while still enjoying some of Colorado’s most spectacular landscapes.

In addition to the full marathon, the event typically offers a half marathon and a 5K, creating a race weekend that welcomes runners of all abilities. The combination of world-class scenery, excellent organization, and a relatively small field gives the Aspen Valley Marathon a boutique feel that distinguishes it from larger urban marathons.
