Immerse yourself in the rugged beauty of Colorado's San Juan Mountains with the Silverton Alpine Runs, an exhilarating trail running experience that takes you through some of the most stunning and historic landscapes. The race offers three distances: an 8-mile jaunt, a marathon, or a grueling 50-kilometer trek along the legendary Alpine Loop. The marathon and 50K courses wind their way past abandoned mining towns like Howardsville, Eureka, Animas Forks, and Gladstone. These ghostly remnants of Colorado's gold rush era are punctuated by breathtaking vistas that include a high point at California Pass, soaring to an elevation of 12,930 feet above sea level. The race then descends through the picturesque Town of Silverton, situated comfortably at 9,318 feet. The marathon course features a total vertical gain of 3,800 feet, while the ultra-distance route climbs an additional 300 feet to reach its impressive elevation mark of 4,100 feet. Both courses start and finish in Silverton, where you'll find yourself surrounded by the charm of this historic mining town. For those looking for a weekend adventure, combining your efforts on the Alpine Loop with Sunday's Kendall Mountain Run presents an unparalleled challenge known as the Mountain Duo Challenge. By tackling either the 8-mile or marathon distance at Silverton Alpine Runs and following it up with the steep ascent to the summit of Kendall Mountain via its classic 12-mile route, you'll earn a unique perspective from atop this iconic peak. Details about course maps, race schedules, pacer information, and additional perks can be found on the official Silverton Alpine website. Race entries are non-refundable and cannot be transferred; however, options for withdrawal and refunds are outlined in their policy documents available online. Volunteers play a crucial role in making these events possible by assisting with setup, aid stations, timing, and breakdown activities. In return, volunteers receive Aravaipa merchandise or race credits as tokens of appreciation. If you're interested in lending a hand while enjoying the run yourself, sign up via their volunteer form to secure your place. Join us for an unforgettable journey through Colorado's scenic San Juan Mountains at Silverton Alpine Runs – where every step is rewarded with stunning views and rich history around every turn.
