Bay to Breakers returns Sunday, bringing citywide closures and transit changes
Downtown and the west side will feel Bay to Breakers first, as closures begin and more than 30,000 runners and walkers head toward Ocean Beach.

Downtown will feel Bay to Breakers first. Streets around Howard Street and Main/Fremont streets, then the Embarcadero and the Financial District, will be the first to absorb the traffic shifts as closures spread through several neighborhoods from May 16 into May 17, with merchants, commuters, and workers along the route facing the earliest disruptions.
The 114th running of the race is set for Sunday, May 17, and more than 30,000 registered participants are expected to run, jog, or costume-walk across San Francisco. The course is a 7.456-mile 12K that has been part of the city since 1912, making it the oldest consecutively run annual footrace in the world. From the start downtown, the route cuts through nine neighborhoods, including Downtown/Civic Center, Hayes Valley, Western Addition, Golden Gate Park, Haight-Ashbury, Castro/Upper Market, Richmond District, and the Sunset District, before ending at Ocean Beach on the Great Highway.

That westward march is why the race still reshapes the city in a way few events can. Bay to Breakers is part athletic race, part street festival, and part civic spectacle, with costume runners, centipede teams linked by bungee cords, and the old tortilla toss tradition still giving the start line its own chaotic character. The course’s best-known grind remains Hayes Street Hill, where the climb between Fillmore and Steiner streets reaches an 11.15% grade and can turn a neighborhood block into a wall of cheers and gasping legs.

Transit agencies are treating the morning like a regional operation. The Market Street Subway will open early at 6 a.m., BART will run four early trains with limited stops that are expected to reach Embarcadero Station around 7 a.m., and Caltrain will provide two special pre-event trains for Peninsula and South Bay riders. One northbound train, No. 925, is scheduled to leave San Jose Diridon Station at 6:04 a.m. and arrive at San Francisco Caltrain Station at 7:20 a.m.

This year’s field is the largest since before the pandemic, and the race is adding a 15K option called the Breaker Bonus with an extra 3K along the Great Highway. The finish also continues to evolve, with runners now coming down JFK Drive and finishing on the road at the Great Highway rather than turning into the Ocean Beach parking lot, a small route change that still says a lot about how San Francisco keeps negotiating public space, congestion, and one of its most enduring civic rituals.
