Prepare for an exhilarating journey where the trail meets the sky at the Calistoga Mountain Run, set for April 12, 2026, in the picturesque town of Calistoga, California. Offering distances for every level of mountain runner—the 50K, 35K, Half Marathon, and 10K—this event promises an authentic test of endurance amidst the stunning natural landscapes of Northern California. Typical race day conditions in April feature comfortable highs around 66°F and lows near 43°F, with a low chance of precipitation, providing ideal weather for tackling the rugged terrain.

The courses, which begin and end on the Great Lawn at the Calistoga Fairgrounds, plunge runners into challenging single-track and fire road trails, including the infamous Oat Hill Mine Trail, the technical Palisades Trail with its sweeping views, Table Rock, and the ascent towards Mount St. Helena. Each distance embodies the true spirit of mountain running, requiring a blend of running, walking, and scrambling. The 50K, often lauded as one of the hardest races in the region, features over 7,250 feet of elevation gain, while the 35K offers intense skyrunning challenges with more than 5,250 feet of climbing. Even the Half Marathon is a relentless mountain climb through breathtaking scenery, and the 10K provides an excellent introduction to the demands and rewards of mountain trail running. The longer distances are recognized as UTMB Index Races, solidifying the event's reputation among the trail running community.

Runners will find well-placed aid stations along the trails and at key points like Highway 29, with specific stops tailored to each distance. However, some sections, particularly on the Palisades Trail, can have gaps of up to six miles between aid, so carrying up to 40 ounces of water is recommended. Drop bags are available for 50K and 35K participants at the Highway 29 aid station. Beyond the challenging trails and remarkable views, the Calistoga Mountain Run fosters a vibrant atmosphere. The central location in Calistoga allows friends and family to explore the charming town and cheer on runners as they cross the finish line, where post-race food and cheer await to celebrate your accomplishment. This event is more than a race; it's a bucket-list mountain experience designed to test your limits and prepare you for a strong racing year.
