About the Ring Out the Old Half Marathon
The Ring Out the Old Half Marathon is held in late December at Woodley Park in Encino, a neighborhood of Los Angeles in the San Fernando Valley. The half marathon runs twice around the park and then once around the 10K loop that passes Lake Balboa, on open paths that cross grass and go under a road through a tunnel. A 10K starts with the half at 7:00 AM and a 5K follows at 7:30 AM. The route is finalized race week, depending on rain.
