Baseball on the bay, basketball in Mission Bay, football forty miles south, and a costume race in May.
Oracle Park
Giants baseball April to October, with the bay behind right field and kayakers waiting for home runs in McCovey Cove. Standing-room tickets are cheap.
Chase Center
Warriors basketball October to April in Mission Bay, walkable from Oracle Park along the water. Tickets are among the dearest in the league.
Levi's Stadium
49ers football September to January in Santa Clara, forty miles south โ Caltrain plus light rail gets there, slowly, on a match day.
Bay to Breakers and Alcatraz
A 12K in May from the Embarcadero to Ocean Beach, run largely in costume, and an open-water triathlon that starts with a swim from Alcatraz in June.
