Ernie Marinoni – 1940 Dispea Race, Photo Credit: Marin History Museum June 14, 2026 marks the 115th running of the Dipsea. This means 1,500 men and women, ranging in age from 8–80, most of them Marin residents, will leave downtown Mill Valley beginning at 8 a.m. and climb up 685 concrete steps, then run seven miles along some of Mt Tamalpais’ most rutted and steep dirt trails and finish in Stinson Beach near the Pacific Ocean. Sound like fun?
