Dipsea Race

The Dipsea Race is the oldest cross-country trail running event—and one of the oldest foot races of any kind—in the United States. The 7.5 mile (12 km) long Dipsea Race has been held annually almost every year since 1905, starting in Mill Valley, and finishing at Stinson Beach, in Marin County, California. The Dipsea celebrated its 102nd running on June 10, 2012. Since 1983, the race has been held on the second Sunday in June.
