HAVANA (AP) — Marathon swimmer Penny Palfrey powered through the Gulf of Mexico on Friday on a record bid to traverse the Straits of Florida, a 103-mile (166-kilometer) unassisted swim testing the limits of human endurance and the will of the high seas.
Slathered with sunblock and lubricant to prevent chafing, the British-born Australian bade farewell to onlookers, dove headfirst into the calm, bathwater-warm seas off Havana and began stroking slowly northward with a kayaker as escort.
"There's a lot of work that's gone into this over the past year," Palfrey said, thanking her husband, her team and Cuban officials who helped facilitate the trip. "It's all coming together, and so exciting to finally get to this point where we can get started."
A member of Palfrey's crew was tweeting to fans, while a webpage updated her location every 10 minutes or so based on data from a GPS device worn by the swimmer. The site showed her making steady northward progress through the Gulf of Mexico.
"Swimming strong. Great conditions. Some jellies, but not bad," read one tweet.
As she hit 10 hours in the water Palfrey had traveled about 18 miles from Cuba, said Andrea Woodburn, who was managing Palfrey's Twitter and Facebook accounts. Woodburn said the evening forecast called for thunderstorms and some gusty winds, but otherwise Palfry's weather expert reported the "situation is about as good as it gets in the Straits."
Palfrey will have to fight through physical and mental fatigue while fending off dehydration, hypothermia and dangerous marine life. She estimates that it will take 40 to 50 hours to make the crossing, and the currents will determine where in Florida she comes onshore.
If Palfrey succeeds, she'll go in the record books as the first woman to swim the Straits without the aid of a shark cage. Instead she's relying on equipment that surrounds her with an electrical field to deter the predators.
Australian Susie Maroney made the crossing in 1997 at age 22, but with a shark cage. American Diana Nyad made two unsuccessful cageless attempts last year on either side of her 62nd birthday, but had to call them off due to a debilitating asthma attack and painful Portuguese man o' war stings. She plans to try again this summer.
Palfrey, a 49-year-old mother and grandmother, is more than a decade younger than Nyad.
She was wearing a regular sporting swimsuit instead of a wetsuit, and planned to put on a porous, non-buoyant Lycra bodysuit that provides cover down to the wrists and ankles whenever jellyfish may be a threat.
That's particularly the case at night, according to her support team of more than a dozen navigators, handlers and medical personnel who were escorting her on the 44-foot (13-meter) catamaran Sealuver.
Palfrey is no stranger to jellyfish stings, which forced her to abort two past swims in Hawaii.
A 20-year veteran of distance swimming, her personal best came last year when she completed 67 miles (108 kilometers) between Little Cayman and Grand Cayman islands.
At a news conference Thursday, Palfrey said she swam competitively in her youth but only discovered ultra-long-distance swimming later in life.
"I spent my teenage years swimming and studying, and then I've spent a lot of time raising my family and supporting my husband's business," she said. "And now I feel that it's my window in life to do something that I love to do. I don't believe that I can do it much later in life so this is my opportunity now. "
Friday morning she was upbeat and focused on the task at hand as she prepared to set off from the Hemingway Marina in western Havana.
Asked about the first thing she planned to do on arrival in Florida, she laughed and said, "get out of the water."
"Beautiful sea, beautiful sunrise. It's a lovely morning in Cuba," Palfrey said. "Thanks. I'm gonna get started."
