Thousands are expected to compete in the crosstown footrace stretching from Downtown, along the Hayes Street Hill, and through Golden Gate Park to the Finish Line at Ocean Beach.
The annual spectacle features some of the world's top distance runners along with a giant street party wearing sneakers. Many people in San Francisco and beyond recognize the Bay to Breakers for the colorful and elaborate costumes worn by some of the participants. Teams of runners known as centipedes often collaborate to resemble animals, vehicles, and references to popular culture.
