Hark the Herald Half Marathon

2025 Hark the Herald Half Marathon & 10K, the 37th annual edition, takes place at Angel Island State Park, Belvedere Tiburon, California. The Half Marathon is two loops on a hilly trail; the 10K is a single loop. The event is limited to 400 participants, creating an intimate atmosphere with panoramic views of the Golden Gate Bridge, San Francisco, Alcatraz, the East Bay and Marin County.

Course markings use orange ribbons; there are no on-course aid stations—runners should carry water, with finish-area refreshments available. Perks include T-shirts and medals for Half Marathon finishers; age-group ribbons are mailed. Ferry access is included in pricing; walkers are welcome on the 10K.
