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 Half Marathon is a single loop on the Bay Area Ridge Trail through the Skyline Ridge, Long Ridge and Russian Ridge Open Space Preserves. It starts and finishes at the Skyline Ridge parking lot on Skyline Boulevard and is roughly six tenths single track and the rest dirt road. This course is the building block for the longer events: the marathon runs it twice, and the 30K adds the five-mile loop to it. It is held on the Saturday of race weekend.
