Zoom San Francisco

Zoom San Francisco begins and ends at East Beach in the Presidio, with all distances heading west along the Golden Gate Promenade. This trail running event offers a 5K, 10K, half marathon, a short sprint, and a free 50-yard kids' dash for very young children. The race is included in Zoom Running Events' coastal calendar, featuring over 20 trail races along the California and Oregon coasts annually. Fields typically range from small to mid-sized, around 100 to 500 participants, with routes utilizing park paths and coastal trails instead of closed city streets. The 5K route ascends the Battery East trail towards the Golden Gate Bridge before returning to East Beach. The 10K and half marathon proceed under the bridge, following the Coastal Trail towards Baker Beach, and traverse the Presidio and Fort Point area. The 10K turnaround is at the Baker Beach aid station, while the half marathon continues through Seacliff to Lands End, with its turnaround overlooking the Sutro Baths. Runners are treated to views of the bridge, the Pacific Ocean, and the Marin Headlands, though the course's tougher coastal terrain positions it more as a trail race than a flat road run. Distances are measured using a Rolatape surveyor's wheel, and youth pricing offers accessibility for families in the shorter races.
