Crystal Springs Trail Run

The SPASM Crystal Springs Trail Run takes place in Woodside, California, at Huddart Park, offering runners a scenic experience through towering redwoods, lush ferns, and trails in Huddart Park, King's Mountain, and Bear Gulch. The event features multiple distances: 8K, Half Marathon, 35K, Marathon, 50K, and a free Kid's Run for children six and under. Courses are well-marked with color-coded ribbons and polka-dot flags indicating turns, traversing single-track trails, dirt roads, and some asphalt.

Elevation gains range from 710 feet (8K) to 4,530 feet (50K). Aid stations stocked with refreshments are spaced every 5-9 miles. The race promotes environmental care by being cupless and encourages courteous trail use. Visit the organization's website for the most recent information.
