Join us at Crystal Springs Picnic Area for 6, 12 or 24 hours of running on the jogging path around the beautiful Harding Golf Course. Located in historic Griffith Park, you can run to your heart's content while the family takes in the sights of Hollywood or just enjoy the many attractions inside the park.

How far can you run, jog or walk in six or twelve hours? You keep going and going and we will calculate your mileage for you. Timed ultra marathon races are super fun because you always have someone to run with and with a flat course and support every 2.43 miles, the miles will add up!
