women’s trail half marathon
October 4, 2025 – 8:00 AM
The Headlands
The Marin Headlands are SFRC’s backyard playground – a network of stunning singletrack, sweeping views, challenging climbs, and exhilarating descents. This fall marks the 3rd annual women’s race through some of Marin’s most iconic terrain. This year’s brand-new half marathon course was thoughtfully crafted to showcase the best the Headlands have to offer – equal parts grit and grace, effort and reward. The race begins and ends at our very own SFRC Mill Valley store, welcoming runners into the heart of the trail community.
