With May now here, it means that the ING Bay to Breakers race is only a few weeks away. This year it will be run on May 18. An incredible 70k participants are expected to run or walk, many of whom will be in costume, which is in part why the Bay to Breakers is such a great spectator event.

The course takes its moving mass through the city’s streets and Golden Gate Park, starting at the foot of the Bay Bridge and ending at the Great Highway, next to the Pacific Ocean. If you’d like to join, online registration is still available (through May 14). The race is open to everyone: pro athletes, weekend runners, families, those in for a Sunday stroll. A unique way to experience San Francisco, Bay to Breakers is a tradition 97 years old.

For more May events, check out our calendar, which will be added to as the month goes on. For now, read about Cinco de Mayo in Dolores Park, Art in the Alley, the How Weird Street Faire, and KABOOM. When any of these fit into your San Francisco itinerary? I hope so.
