Course Details

The course is a hilly loop trail that goes around Angel Island. The Half Marathon consists of two loops of this trail, while the 10K is a single loop. The event offers panoramic views of the Golden Gate Bridge, San Francisco, Alcatraz Island, the East Bay, and Marin County.

A course cut-off time of 3.5 hours is enforced. There are no aid stations on the course, so runners are recommended to carry their own water. An aid station is available for Half Marathon participants before they start their second loop.
