Are those naked people you see trotting through the fog? Yes! But why? It must be Bay to Breakers (www.ingbaytobreakers.com)! On the third Sunday of May every year since 1912, San Franciscans have gotten up early to get to the starting line of the legendary 12K race.

But Bay to Breakers is like no other race in the world. Sure, there are plenty of serious runners who enter the race to win it or to challenge themselves and their abilities. And then there are the other racers…San Franciscans and visitors who turn out by the thousands wearing astonishing outfits, pulling carts and wagons, and stripping down to the buff as they make their way along the course without any care for their pace.

A huge audience packs the racecourse, eager to see costumes and conveyances that may well be recycled for Pride the following month. If you want to participate in B2B, check the website for all the details you’ll need. Specatators can also scope out the course location and best spots to find a place to watch.
