SAN FRANCISCO (KGO) -- Thousands of people hit the streets of San Francisco Sunday morning for "America's most beautiful run."
The annual Bridge to Bridge Run, both the 5K and 12K, started at 8 a.m. in front of the Ferry Building.
Runners pass through Fisherman's Wharf and Ghirardelli Square. They will make their way to Crissy Field for a panoramic view of the Golden Gate Bridge, then loop back to the Marina Green where the run ends.
The race benefits the Special Olympics.
