Australian endurance athlete Chloe McCardel expects to take about 60 hours to get from Cuba to the Florida Keys, a little more than 100 miles.
June 12, 2013 Australia’s Chloe McCardel waves to waiting journalists as she arrives at Cuba’s Hemingway Marina to begin her swim to Florida from the waters off Havana. McCardel, 28, is bidding to become the first person to make the Straits of Florida crossing without the protection of a shark cage. American Diana Nyad and Australian Penny Palfrey have attempted the crossing four times between them since 2011, but each time threw in the towel because of injury, jellyfish stings or strong currents. Australian Susie Maroney did it in 1997, but with a cage. Ramon Espinosa/AP Buy Photo
