1. Bay to Breakers

#1 Sports Event
Officially, Bay to Breakers is the oldest consecutively run footrace in the world: a 12K that lures more than 40,000 serious runners from the Bay to the Pacific Ocean. Unofficially, it’s a costume parade that draws revelers from all walks of life for an end-to-end tour of the city, with the requisite house parties and dance stops along the way. The Alaska Airlines-sponsored event has hosted more than two-million registered runners over the last century. Between the naked, costumed runners and tethered teams, it’s one of the most unique sporting events in the world. Next: May 19, 2019

3. Cal vs. Stanford Football Game

#4 Sports EventÂ
Cal and Stanford are slated to meet in Berkeley once again for the 121st occurrence of the “Big Game” since 1892. The in-state rivalry runs deep, but the Cardinals have been routing the Bears regularly for the last eight years and lead the series overall, 63-46-11. Players may reflect on the game in terms of victory or defeat, but it’s a clear win for student spectators at both schools, who enjoy a week of school spirit events on their respective campuses before the game.

5. San Francisco Marathon

#6 Sports Event
It takes the average tourist a full day to wander between San Francisco landmarks like Coit Tower, Fisherman’s Wharf, and the Golden Gate Bridge, but the 27,500 runners in the San Francisco Marathon dash past those points in less than six hours. The Mission? Check. Haight-Ashbury? Done. Huffing and puffing up an iconic hill while 80,000 spectators cheer? You bet. The race is the ultimate San Francisco bucket list and a workout, all in one. Biofreeze is the title sponsor. Next: July 28, 2019

6. KNBR FanFest

#7 Sports Event
Supporting the Giants when they’re enjoying their even-year-World-Series winning streak is easy, but 30,000 true fans queue up to meet the boys in black and orange each winter, win or lose. At KNBR’s Fan Fest, players and fans rub elbows, sign autographs, and pose for selfies at AT&T Park before the team heads to Arizona for spring training. Those hoping to get face time with the likes of Hunter Pence, Pablo Sandoval, and Buster Posey show up early; autograph lines at FanFest can be almost as scary as Brian Wilson’s beard.

8. Waves to Wine

#9 Sports Event
A two-day ride from San Francisco to Sonoma County becomes infinitely more enjoyable when there are scenic stops, snacks, and drinks every 12 to 15 miles on the way to your destination.

Last year, more than 1,500 cyclists participated, raising more than $1.6 million for the organization in the process. Next: September 22-23, 2018
