Runners make their way up Hayes Street in San Francisco during the Bay to Breakers race on May 18, 2025.

More than 30,000 runners, some in elaborate costumes and others forgoing clothes altogether, are set to descend upon San Francisco for the annual Bay to Breakers race on Sunday. And in preparation for the running holiday, the San Francisco Municipal Transportation Agency is set to shut down several streets.

The race is scheduled for Sunday at 8 a.m. at Howard and Fremont. But citygoers should prepare for a much more gridlocked San Francisco on Saturday, particularly in downtown, and through the afternoon on Sunday all across the city. The following streets will be closed during the weekend.
