All About San Francisco's Wackiest Race

Zappos.com Bay to Breakers

The mobile party of the racing world is known today as Bay to Breakers. Held in San Francisco on the third Sunday in May, the race has been running every year in the Fog City since 1912 and is one of the city's "Must Do" things. For those interested in participating in an upcoming race, or are simply just interested in the hard facts, here is a comprehensive list of the Bay to Breakers records, along with some other cool tip-bits about this one-of-a-kind event.

Bay to Breakers Race Course

Bay to Breaker's course starts in the the city's sea-level Embarcadero area, on Howard and Beale streets, along the San Francisco Bay. The 7.46-mile course (12 kilometers) is largely flat, but at the 2.5-mile mark racers encounter the infamous Hayes Street Hill, a five-block stretch that rises 215 feet above sea level. It's a massive, though worthwhile, challenge for many racers, and the course is mostly (and gradually) downhill from there. The race then continues along SF's Panhandle park, through the iconic Golden Gate Park, and culminates at the Great Highway, otherwise known as the "breakers".

Bay to Breakers Participants

While anyone and everyone can participate, the serious athletes stick to the front of the pack and are usually led by Kenyan and Ethiopian runners who fly into San Francisco each year to compete. These star athletes are followed by tens of thousands of runners, joggers, and walkers, many in costumes, in various states of dress and un-dress, and eve linked together as "centipedes." The rules of this race are pretty lax, as recent years' estimates have said that up to half of Bay to Breakers participants were not registered for the race.

Even the former mayor of San-Francisco, Gavin Newsom was among the non-registered racers in 2010.
