Mt. Umunhum Trail Conquest-Winter

Embark on a challenging and scenic winter trail adventure at the Mt. Umunhum Trail Conquest on January 31, 2026, in San Jose, CA. Starting from the Hacienda Entrance of Almaden Quicksilver Park, this race plunges runners into the heart of the Sierra Azul Open Space Preserve, offering distances ranging from a 1M and 5K to a Half Marathon, 7M, 30K, Marathon, and a demanding 50K ultra. Runners can expect typical race day conditions with pleasant highs around 62F and lows near 43F, and only a 10% chance of precipitation, making for ideal trail running weather.

The courses are renowned for their significant elevation gains and diverse terrain, with approximately 95% unpaved trails. Shorter distances offer a taste of the park's rolling hills, while the 30K ascents Bald Mountain, climbing over 5,000 feet. The ultimate challenge lies in the Marathon and 50K events, which conquer the "exclusive" Mt. Umunhum, reaching its majestic summit with over 7,600 feet of ascent for the 50K. The trails wind through mystical oak forests, chaparral, and pine woodlands, eventually opening up to breathtaking 360-degree vistas of the Santa Clara Valley and surrounding ridgelines from the summit. Aid stations, equipped with toilets at key locations, are strategically placed along the well-marked courses to support your journey.

Mt. Umunhum holds deep historical and cultural significance, being sacred to local Native American people and featuring a distinctive Cold War-era radar tower at its peak. This adds a unique layer to the stunning natural beauty and rigorous physical test the race provides. Whether you're aiming for a personal best on an undulating 7-mile course with 1,529 feet of ascent, tackling the Half Marathon's 3,159 feet of climb, or pushing your limits on the ultra distances, the Mt. Umunhum Trail Conquest promises an unforgettable experience amid the picturesque wilderness of the Bay Area. All finishers are rewarded with a commemorative medal.
