Swimmer Diana Nyad prepares for an ocean swim in Key West, Florida September 24, 2010. Veteran long-distance swimmer Nyad looks as tough as nails as she talks about setting out soon on a treacherous swim of more than 100 miles (160 km) from Cuba to Key West, Florida. She is 61 years old but coils up like a middle-weight prize fighter as she speaks of digging in with her broad shoulders and powerful arms and "boxing the waves" on the swim across the Florida Straits. "It's supposedly going to be maybe 2-1/2 days or so, 60, maybe 65 hours, and that's if I get maybe pretty good conditions," Nyad said in an interview on Friday.
