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.

Transit options
Muni lines will also see service disruptions, according to SFMTA.
“If you’re not participating in the race as a runner or spectator, you are encouraged to avoid areas affected by the Bay to Breakers,” SFMTA said on its website.

The agency said to expect crowding and delays on the N Judah, 5, 28, 29 and 31 bus routes, which are all parallel to the course. However, it’s adding additional service to the 5R, 18, 28 and N Judah lines to accommodate.
Some routes that cross the course will also see changes. Bus routes 14, 14R, 19, 22, 24, 27, 33 and 43 will not have service between sections. Riders will have to walk to get from one side of the race to the other. Bus routes 30 and 45 will not service South of Market, and the 49 will not serve south of Van Ness Avenue and McAllister Street or north of Van Ness and Market streets. And bus routes for Market and Mission — 6, 7, 9, 14, 49 and KLM Owl routes — will only go to Market, 10th or 11th street.
BART is encouraging race participants to take one of its four trains as part of its extra service, which will get racegoers to Embarcadero Station by 7 a.m. Caltrain is also running two special early-morning service trains, one from Palo Alto and one from the San Jose Diridon Station, with limited stops.

A list of reroutes is available on SFMTA’s website, and the agency encourages travelers to call the San Francisco 311 Customer Service Center “for personalized trip assistance.” Riders can also sign up for real-time Muni service alerts through an email or text subscription.
