Bay to Breakers — Annual Costumed City Run

Bay to Breakers returns to San Francisco on Sunday, May 17, with organizers billing this year’s edition as the latest running of a race that began in 1912. The official event site says the race includes a traditional 12K and an optional 15K “Breakers Bonus,” with the course starting downtown and running west to Ocean Beach. San Francisco Travel says the event is held on the third Sunday in May and is one of the world’s oldest footraces. Bay City News reported that more than 30,000 runners have registered for the 2026 race. ### Where does the race actually start and finish? Howard Street and Fremont Street is the starting point for all race distances, according to the official 12K event page. The site says the first wave starts at 8:00 a.m. and the last wave at 8:45 a.m. The Embarcadero neighborhood is where the race begins in broader geographic terms, and the route runs through nine San Francisco neighborhoods before ending at the Great Highway by Ocean Beach, the official site says. (baytobreakers.com) KRON reported the course heads up Howard Street to Hayes Street, then onto Fell Street and through Golden Gate Park on JFK Drive before the finish. ### How long is Bay to Breakers in 2026? (baytobreakers.com) The 12K race is the core event, and the official site describes it as a 7.45-mile route across the city. Organizers are also offering a 15K option that adds a 3K extension along the Great Highway. 12:30 p.m. is the course cutoff at the intersection of JFK Drive and Chain of Lakes in Golden Gate Park, according to the 12K page. The finish line closes at 1:00 p.m., the site says.

(baytobreakers.com) The tourism group says Bay to Breakers later became known for mixing serious runners with costumed participants and large crowds. Groups of 13 to 15 runners can enter the event’s “Centipede” division, where teammates are linked by a bungee cord or another safe mechanism, according to the official centipede page. The site says seeded and sub-seeded centipedes are eligible for awards in the 12K race. ### What should people expect on streets and transit? Saturday, May 16, and Sunday, May 17, are expected to bring road closures across downtown and along the race route, according to KRON and SFGATE reports citing SFMTA information. (sftravel.com) KRON said closures begin as early as 3 a.m. Sunday on some streets and extend into the afternoon near the western end of the course. (baytobreakers.com) Caltrain said the starting line is about 1.4 miles from the San Francisco station at Fourth and King streets, and riders can also connect to Muni. Caltrain also said Bay to Breakers does not allow alcohol or floats on the course. ### What do runners get, and is there a virtual option? The official race site says registered runners receive a finisher’s medal, event shirt, finish-line festival access and water or aid stations. (kron4.com) Chip-timed results are included for VIP participants, and the site lists a VIP add-on at $109. Virtual participation remains available for runners who are not in San Francisco, according to the official 12K page. (caltrain.com) The site says virtual entrants can run either the 12K or 15K distance on their own route and submit proof through the event’s online system. ### What happens next on race day? Sunday, May 17, is race day, with waves starting from 8:00 a.m. in downtown San Francisco and the finish line closing at 1:00 p.m., according to the official event page. (baytobreakers.com) Organizers say route details, registration and race-week information are available on the Bay to Breakers website, while San Francisco agencies and transit operators have posted closure and detour notices for the weekend.
