Zoom San Francisco

The Zoom San Francisco trail races take place in San Francisco, California, in late March. All races start and finish at East Beach and head west along the Golden Gate Promenade: the half marathon (13.1 miles) starts at 8:30 a.m., the 10K (6.2 miles) at 8:55 a.m. and the 5K (3.1 miles) at 9:10 a.m.

Different distances follow different routes. Some climb the Battery East trail to the Golden Gate Bridge, while others continue under the bridge and along the coastal trail with panoramic views of the Pacific. The routes pass landmarks such as Baker Beach, Seacliff and Lands End, with a view of the historic Sutro Baths. Coastal fog and wind are common in March, so bring layers, and expect stairs and climbs on this terrain.
