About This Race

Lace up for an unforgettable journey into the heart of the Mojave Desert at the Calico Trail Run, an annual adventure taking place on January 25, 2026, in Yermo, CA. This race is more than just a run; it's an exploration through the historic Calico Ghost Town and its surrounding rugged, yet beautiful, Calico Mountains. Offering both a challenging 50K and a formidable 30K, participants will navigate courses that are approximately 95% unpaved trails, immersing themselves in scenery rich with California's mining history.

The Calico Trail Run promises a truly unique experience with its diverse and demanding terrain. Runners will encounter everything from lengthy uphill sections on loose gravel to technical, rocky fields, steep ascents, and thrilling downhill canyon running, including a notable "butt-sliding" descent in Odessa Canyon for the 50K. Expect to weave past old mines on jeep roads, traverse sandy washes, and even pass through an old mining cave, all while soaking in the awe-striking views of the desert mountain ranges. The 50K features a significant 3,893 feet of elevation gain, with a high point of 3,500 feet, ensuring a substantial physical and mental test. Aid stations are well-placed and fully staffed by supportive volunteers, complete with porter potties, making this a well-supported, albeit challenging, low-key event.

As a USATF-sanctioned event and a highlight of the Southern California Ultra Runners Grand Prix Series, the Calico Trail Run has built a reputation since its inception in 2004 for its well-marked courses and exceptional atmosphere. The start and finish in the restored Calico Ghost Town add a distinctive charm, with one reviewer recalling a "mocked gunfight" at the finish line. Runners can anticipate typical race day conditions with highs around 63°F and lows near 36°F, with a minimal 2% chance of precipitation, providing ideal cooler temperatures for tackling the desert trails. Prepare for an adventure you won't soon forget, where rugged beauty and historical intrigue combine to create an extraordinary trail running experience.
