As successful swim attempts through the Northern California Open Water Swimming Association occur, swims will be ratified on a rolling basis as the Ratification Committee reviews the data from each swim.
Circumnavigation of San Francisco - 21 miles (33.8km)
The 21-mile swim around San Francisco is not for the faint of heart. The County of San Francisco is the northern tip of the San Francisco Peninsula with the Pacific Ocean on one side, the Golden Gate and San Francisco Bay on the other sides. Swim the three sides of San Francisco County crossing the SF / San Mateo County line to start and crossing it again to finish.| Name | Type | Country | Route | Time | Date |
