San Francisco Marathon in San Francisco
First run in 1977 by the Pamakids Runners Club during the 1970s distance-running boom, the San Francisco Marathon starts and finishes near the Embarcadero and Ferry Building, sweeping past Fisherman's Wharf, through the Presidio, and across the Golden Gate Bridge twice before returning to the city each July.
Its Golden Gate Bridge route and city setting give it strong travel appeal.
