Let's hear it for...the world class runners who lead a very large group of serious runners over a challenging 12 km course, the committed runners who compete for their best time, the serious walkers who love being active and engaged, the great bands along the course who provide awesome music, the many thousands of creatively costumed runners and walkers, and an especially big cheer for those who add the spice to the race - those who brave cool, brisk temperature to run and/or walk the distance without any clothes at all.

The Bay to Breakers is an amazing event. It's a San Francisco classic.
