Event Overview
The Calistoga Mountain Run is a trail running event with distances of 50k, 35k, a half marathon, and a 10k. It starts in downtown Calistoga, California. The routes take runners onto trails and into Robert Louis Stevenson State Park. The courses are described as challenging and technical, involving climbing toward Mount St. Helena.
Course Details
The races are out-and-back courses on single-track and fire roads. The terrain is rocky and steep in sections, requiring varied running and hiking techniques. Key trails used include the Oat Hill Mine Trail, Palisades Trail, Table Rock Trail, and Mount St. Helena Trail.
Distances and key facts:
- 50k: Features over 7,500 feet of elevation gain. Runners visit three fully stocked aid stations multiple times for a total of six stops.
- 35k: Has a net elevation gain/loss of 5,250 feet. Runners have three aid station stops.
