The Escape from Alcatraz Triathlon is not the top of the worldwide triathlon craze. Participants are checked for health before allowed to participate, yet, as with other similar events, this one also ended with someone killed. A 46-year-old athlete died of a heart attack just moments after entering the water. I never understood why Alcatraz was considered so secure since it is only 1.5 Km from San Francisco port - not even long distance swimming. But the water is cold.
