Horseshoe Lake Trail Run

The Horseshoe Lake Trail Run is held at the Skyline Ridge Open Space Preserve in La Honda and uses trails within Skyline Ridge, Long Ridge, and Russian Ridge Open Space Preserves. The majority of the route follows the Bay Area Ridge Trail and includes views of the Pacific Ocean and the Santa Cruz Mountains. Distances were measured with a Rolatape surveyor's measuring wheel.
