Why Is Swimming the Most Deadly Leg of a Triathlon?
By Larry Greenemeier, Scientific American
Sunday's Nautica New York City Triathlon resulted in two deaths, both from cardiac events that arose during the event's initial swimming leg. A 64-year-old man and a 40-year-old woman were pulled from the Hudson River before they could complete the 1.5-kilometer swim from a wharf near Manhattan's 96th Street down to the West 79th Street Boat Basin. Both athletes were taken to a nearby hospital in cardiac arrest.
