Cancelled Event

THIS EVENT HAS BEEN CANCELLED

2020 Quad Cancelled

It became clear a few months ago that we would not be able to hold a traditional Quad Dipsea on Saturday November 28th, even with COVID protocols & procedures in place. Over the past month we developed a format for a virtual race, which would have been held on the course, over a month-long period. Although the City of Mill Valley and the National Park Service were accepting of such a format, California State Parks considers a virtual race an organized event, and is not allowing any events to occur on State Parks lands through at least the end of the year. Therefore we have cancelled the 2020 Quad Dipsea.

We plan to return for the 38th Quad Dipsea on Saturday November 27, 2021.

Until then, stay safe, be considerate of others, and VOTE!

Course

Stairs, hills, and more hills. About 9,000 feet of vertical packed into 28 miles.  It begins at 7:30AM at Old Mill Park (Throckmorton Avenue, Cascade Way, & Old Mill Street intersection), in Mill Valley, California. Within a few hundred yards the course heads up three flights of stairs as tall as a fifty-story building, and up some more through an old horse ranch to Windy Gap. Then it plunges down into Muir Woods, across Redwood Creek, and begins a tough grind up through both trees and grasslands over trail sections named "Dynamite", "The Hogsback", "The Rainforest", and "Cardiac." At the top of Cardiac, the course levels out with panoramic views of the Pacific Ocean before it plunges down over the rocks, roots, and stairs of "Steep Ravine" and the discouragingly steep but short climb up "Insult Hill." Finally, as the course follows the relatively gentle slope of The Moors toward the ocean, Stinson Beach is in sight a mile ahead. 

Once to Stinson, you turn around an head back to Old Mill Park following the same course. 

And then do it all over again for the QUAD!!

Note: unlike the Dipsea and Double Dipsea, the Quad Dipsea does not allow shortcuts. You must stay on the Dipsea Trail the entire way.)
