Escape from Alcatraz (triathlon) first Escape from Alcatraz was proposed by Joe Oakes after he participated in the 1979 Ironman Triathlon in Hawaii. The first Escape from Alcatraz race was held two years later in June 1981, with members of the Dolphin Club testing the course. The course started with a swim from Alcatraz Island in the middle of San Francisco Bay to the city of San Francisco, a bike ride over the Golden Gate Bridge to Mill Valley in Marin County, and an out-and-back running course over Mount Tamalpais to Stinson Beach and back. The running course followed the course of the Dipsea
Escape from Alcatraz (triathlon) foot race, but by making it an out-and-back run rather than a one-way course, became known as a "Double Dipsea". The course has remained the same over the years and celebrated its 35th anniversary in 2015. Participants are limited to members of the Dolphin Club and The South End Club. The Dolphin Club is the host and sponsor of the event. The annual public Escape from Alcatraz triathlon, organized by IMG, now takes place in early June. The current course consists of a swim starting near Alcatraz Island, a run from the bay to the transition zone at Marina Green,
