Embark on an unforgettable high-altitude adventure at the Silverton Alpine Runs on July 18, 2026, in the historic town of Silverton, Colorado. Organized by Aravaipa Running, this challenging event offers a 50K, Marathon, and 8-mile distance, inviting runners to experience the breathtaking beauty and rugged terrain of the San Juan Mountains. All courses traverse sections of the iconic Alpine Loop jeep roads, guiding participants through a landscape dotted with ghost mining towns such as Howardsville, Eureka, Animas Forks, and Gladstone. Runners in the 50K and Marathon distances will ascend to a remarkable 12,930 feet atop California Pass, while the 8-miler provides a scenic out-and-back taste of the alpine environment. Be prepared for steep climbs, rocky sections, and potentially dusty conditions from shared use with recreational vehicles, all against a backdrop of truly spectacular mountain vistas.

The Silverton Alpine Runs are renowned for their demanding yet rewarding nature, with a significant elevation profile that challenges even seasoned trail runners; proper acclimatization is highly recommended. Aid stations, strategically placed along the route (including key stops at Howardsville, Eureka, Animas Forks, California Pass, and Gladstone), are well-stocked with water, electrolytes, and a variety of snacks to keep you fueled. As a cupless event, participants are asked to carry their own hydration vessels, aligning with the race's commitment to Leave No Trace principles. The start and finish lines are conveniently located at Silverton Memorial Park on Greene Street, where crew and spectators can offer support.

Typical race day conditions in mid-July feature comfortable highs around 80°F and lows around 53°F, with a relatively low 13% chance of precipitation. Beyond the individual races, runners can also take on the unique Mountain Duo Challenge by pairing any Silverton Alpine distance with the Kendall Mountain 12-mile race the following day, offering an extended weekend of high-country trail running. Praised by runners for its stunning scenery, excellent organization, and supportive atmosphere, the Silverton Alpine Runs promise an unforgettable journey through a historic and majestic corner of Colorado.
