Bay Bridge Half Marathon

Bay Bridge Half Marathon runs in Oakland, California, on May 2, 2027, with a half marathon (13.1 miles) at 8:15 a.m. and a 5K at 8:30 a.m. It is the only race that takes runners across the new span of the Bay Bridge, between Oakland and Treasure Island. The route starts in West Oakland, stays flat and fast early on, then climbs onto the bridge bike path. From up there you get the Golden Gate Bridge, Alcatraz, and the San Francisco skyline on one side, and the Oakland cranes and the rolling East Bay hills on the other. Music, local partners including Oaklandish and Old Kan Beer, a busy expo, Cinco de Mayo festivities, and post-race food fill out the day.

The profile shapes how you should race it: bank an even effort, not an even pace, because the flat opening miles tempt you into spending too much before the climb onto the bridge. It is not the flattest course for a personal best, but it rewards a 12- to 16-week build with a weekly long run and one tempo session on rolling ground. The event comes from the team behind the original US Half across the Golden Gate.
