Comfortable temps

Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.

Race Info

The Horseshoe Lake Trail Run 50K runs the marathon course and then adds the five-mile loop, all in the Skyline Ridge, Long Ridge and Russian Ridge Open Space Preserves above the Santa Cruz Mountains. It starts and finishes at the Skyline Ridge parking lot on Skyline Boulevard and passes through the start area several times, so runners can reach their drop bags between laps. Most of the route is single track and dirt road along the Bay Area Ridge Trail, with long ridgeline climbs and views toward the Pacific. It is the longest and hilliest distance of the weekend, held on the Saturday of race weekend.
