Half Marathon Course Description
Start/Finish at the north end Lake Merced Parking Lot (foot of Sunset Blvd). Run three clockwise loops around the lake staying entirely on jogging/pedestrian path. The 1st loop is cut shorter by crossing the east side of the “drawbridge” at the southern end of the lake. There will be at least one aid station per 4.5 mile loop with Water/Nuun near the start/finish area. If you need water more often, please carry a water bottle to refill at each loop. There is also a water fountain in the parking lot near the picnic tables on John Muir Dr around 2.5 miles.

The 4.5 mile race is one clockwise loop around the lake.
