Dipsea Race Mill Valley, CA   Jun 14, 2026

First run in 1905, the Dipsea is the oldest trail race in America. It is run every year on the second Sunday in June. The scenic 7.4 mile course from Mill Valley to Stinson Beach is considered to be one of the most beautiful courses in the world. The stairs and steep trails make it a grueling and treacherous race. And its unique handicapping system has made winners of men and women of all ages. Because of its beauty and challenge, it is a very popular event, and because of safety and environmental concerns the number of runners is limited to about 1,500. While racers enter from all over the world, the Dipsea is primarily a Northern California event and the entry process is tilted slightly to favor local contestants.
