At a place they call "Land's End" at the mouth of the bay on the San Francisco side.
At the ruins of the old Sutro Mansion, looking South to Pacifica. Check out the windmill on the left, that's Golden Gate Park. That long stretch of Highway is called the "Great Highway" and is part of the route for the Nike Women's marathon. Half-Marathoners come out of the park and head to the beach for the finish. Full-Marathoners turn left and go down the highway and around Lake Merced before coming back the same way and finishing at the beach. The aid station that I've worked at for the past two marathons is on that highway.
Passing by the bridge on my way home. Finished in the cover of darkness.
