Escape from Alcatraz Triathlon

Second Sunday in June. Participants (which often include world champions and Olympic medalists) swim 1.5 miles through chilly waters, bike 18 miles, and then run an extra 8 miles. The course winds its way throughout the city, but the transition and finish line is at Marina Green in the Golden Gate area.
