The meeting place is at the west end of the St Francisco Yacht club parking lot, located at 99 Yacht Rd (https://maps.google.com/?q=99+Yacht+Rd&entry=gmail&source=g). The course starts on the San Francisco Bay Trail . It heads due west, towards the Golden Gate Bridge, for approximately 1.1 miles. At the intersection of the trail with Old Mason Street and Marine Drive it takes a hard left turn onto the sidewalk of Old Mason Street. After approximately 0.5 miles (keeping out of the bicycle lanes on the sidewalk) the course takes two left turns on dirt paths (with sweeping views of both Alcatraz and the bridge) before re-joining the sidewalk on Old Mason Street now running in the opposite direction. The course then retraces the outbound route (with a sharp right at the intersection of Old Mason Street and the Bay trail) to the finish at the meeting place.
