VIDEO: Experiencing Bay to Breakers 2011

The 100th annual Bay to Breakers has come to be known as one of the most unique footraces in the country.

At 7 a.m. athletes and citizens fill the streets of San Francisco to run, jog, walk and drink their way across the seven-mile course that stretches from one side of the bay to the other.

Three hours later, Bay to Breakers transformed from a race to a full-blown city-wide dance party.
