Come celebrate Earth Day the best way possible: running through one of San Francisco's most magical hidden gems. Sutro Forest is a mossy, eucalyptus-lined escape right in the middle of the city, and we're taking it over for an evening with Trail Sisters and Athleta.
Trail Sisters is a FWTNB running community: we organize no-drop runs in Marin County and around the bay. We strive to make the outdoors more accessible and to create a supportive community.
We'll meet at the corner of Willard and Frederick at 5:45 PM and start running at 6PM and keep the pace fun and inclusive. We will stop at intersections to allow the group to stay together. This is a hilly run on trails, trail running shoes are recommended but not mandatory. The route is here:
