Course
Stairs, hills, and more hills. 9200 feet of vertical packed into 28.4 miles.
It begins at the Old Mill Park, then 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 the trees over trails named "Dynamite" and "Cardiac." At the top of Cardiac, the course levels out before it plunges down through the "Swoop", over the rocks and roots of "Steep Ravine" and the discouragingly steep 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.)
