KEY WEST, Florida (AP) — With her lips and tongue swollen, U.S. endurance swimmer Diana Nyad edged closer to Florida on Monday in her attempt to become the first person to swim the treacherous waters from Cuba to Key West without a shark cage.
Nyad was about 2 miles (3 kilometers) from Florida late Monday morning and on course to swim about 110 miles (177 kilometers). She was expected to arrive in Key West on Monday between 2 p.m. and 4 p.m. EDT.
"I am about to swim my last 2 miles in the ocean," Nyad told her 35-member team from the water, according to her website. "This is a lifelong dream of mine and I'm very very glad to be with you."
Nyad told supporters a silicone mask she wore to protect her face from jellyfish stings caused bruises inside her mouth, making it difficult for her to talk.
Doctors traveling with Nyad were worried about her slurred speech and her breathing, but they have not intervened, according to Nyad's website.
Nyad's journey began Saturday morning when she jumped from the seawall of the Hemingway Marina into the warm waters off Havana. She has been swimming the Florida Strait ever since, stopping from time to time for nourishment.
She had gotten very cold overnight, her team said, so they decided not to stop her to eat and drink in hopes that swimming would keep her warm.
"I admit there's an ego rush," Nyad said before the swim began. "If I — three days from now, four days from now — am still somehow bringing the arms up and I see the shore ... I am going to have a feeling that no one yet on this planet has ever had."
Nyad, who recently turned 64, tried the swim the Strait three times in 2011 and 2012. She had also tried in 1978.
Her last attempt ended amid boat trouble, storms, unfavorable currents and jellyfish stings that left her face puffy and swollen.
This time she wore a full bodysuit, gloves, booties and a mask at night, when jellyfish rise to the surface. Before the swim, she said the kit slowed her down, but she believed it would be effective.
The support team is accompanying her has equipment that generates a faint electrical field around her, which is designed to keep sharks at bay. A boat also drags a line to help keep her on course.
Australian Susie Maroney successfully swam the Strait in 1997 with a shark cage, which besides protection from the predators, has a drafting effect that pulls a swimmer along.
In 2012, Australian Penny Palfrey swam 79 miles toward Florida without a cage before strong currents forced her to abandon the attempt. This June, her countrywoman Chloe McCardel made it 11 hours and 14 miles before jellyfish stings ended her bid.
In 1978, Walter Poenisch, an Ohio baker, claimed to have made the swim using flippers and a snorkel. Critics say there was insufficient independent documentation to verify his claim.
Nyad first came to national attention in 1975 when she swam the 28 miles around the island of Manhattan in just under eight hours. In 1979 she swam the 102 miles from North Bimini, Bahamas, to Juno Beach, Fla., in 27.5 hours.
Nyad is also an author of three books, a motivational speaker and has been a reporter and commentator for NPR.
