Now in it's 32nd year, the Dolphin Club Escape from Alcatraz is the original Escape from Alcatraz. The event begins with a jump off a ferryboat and swimming (no wetsuits allowed) from Alcatraz to Aquatic Park. A quick transition, then a 14-mile bike ride over the Golden Gate Bridge to Mill Valley. From there you'll run the Dipsea Trail over Mount Tamalpais to Stinson Beach, turn around, and run back to Mill Valley, for a total of 13 miles.
