To many, running 7.5 miles is a loathsome task, much less a cause for celebration. But each year, on the third Sunday of May, thousands of people turn what would otherwise be just your average San Francisco footrace into a moving block party complete with costumes, house parties, and plenty of refreshments.
Since its inception in 1912, Bay to Breakers has evolved from a typical footrace into a unique spectacle. The first race, known as the “Cross City Race,” was conceived as a morale booster following the devastating 1906 earthquake. On New Year’s Day 1912, 140 people lined up at the Embarcadero for the inaugural event. The course has varied over the years but consistently starts near the Ferry Building and ends at Ocean Beach.

The first costume in the race appeared in 1940, by the mid-1970s, a “carnival atmosphere” had taken hold, influenced by San Francisco’s cultural shifts. Participants began to don a wide array of costumes, from clowns to riverboat gamblers, and the race saw its first unofficial female finisher in 1940.
Despite its festive atmosphere, the race has faced challenges, including safety concerns and neighborhood complaints. In recent years, measures have been taken to mitigate issues such as public urination and excessive trash. These efforts highlight the balance race organizers strive to maintain between preserving the event’s free-spirited nature and addressing the practical needs of participants and residents.
“I don’t know what it is, but it seems fun,” Mina, a recent transplant, told us. Despite fluctuations in attendance and changing dynamics, Bay to Breakers remains a beloved tradition, embodying the spirit and resilience of San Francisco.
