San Francisco’s Zappos.com Bay to Breakers is the oldest consecutively run annual footrace in the world, a staple to the City by the Bay since May 1912. With a starting point near the San Francisco Bay, a few blocks from The Embarcadero, the 12K race runs west through the city and finishes at the Great Highway where breakers crash onto the Pacific Coast’s Ocean Beach. A quintessential San Francisco experience for 103 years, the race is interwoven into the fabric of the city and is a true reflection and celebration of life between the breakers and the Bay.
The event is well known for many participants wearing costumes, and a few engaging in varying degrees of public nudity. From 1986 to 2010, it was officially the world's largest footrace with 110,000 participants, until it was surpassed by City2Surf event in Sydney. Attendance in 2015 was reported at roughly around 50,000.
