About the race
The Quad Dipsea is a trail ultramarathon composed of two out and back trips along the Dipsea Trail. The course starts and finishes at Old Mill Park in Mill Valley, California. Short cuts are not permitted; the trail must be run as marked.
Most of the route is single track and includes many stair sections, with 686 stairs in the first three flights. There are stretches of clean trail and stretches with roots and rocks. The course covers 28 miles with a total of 9,200 feet of ascent and an equal amount of descent.
Aid stations are located at Cardiac, Stinson Beach, and Old Mill Park and are stocked with standard ultra supplies and GU Roctane Endurance Drink. Races that take place within the GGNRA may not distribute gel packets, so participants must carry their own gels. Drop bags may be left at the Old Mill Park turnaround at mile 14 only; drop bags are not transported to other aid stations.
Runner tracking is provided by Ultralive.net. Volunteers are requested for the event and receive a free beanie. Visit the organization's website for the most recent information.
