The Quad Dipsea is two out-and-back trips along the famed Dipsea Trail. The race starts and finishes at Old Mill Park in Mill Valley, California. Unlike the (single) Dipsea and Double Dipsea, short cuts are not permitted! You must run the trail as marked.
Most of the trail is single track. There are LOTS of stairs - 686 in the first three flights alone, some stretches of clean trail, and some stretches with a lot of roots and rocks. There is a total of 9200 feet of climb and an equal amount of descent in the 28 miles.
