The 29-year-old, who is bidding to become the first person to make the 100-mile Straits of Florida crossing without the protection of a shark cage, said Monday that the challenge has great allure for top athletes.
“At the moment it’s the most high-profile marathon long-distance swim, and swimmers really want to come here and be the first,” McCardel said. American Diana Nyad and Australian Penny Palfrey have attempted the crossing four times between them since 2011, but each time threw in the towel part way through because of injury, jellyfish stings or strong currents. Australian Susie Maroney did it in 1997, but with a shark cage.
McCardel said she hopes to help bring Cubans and Americans closer by symbolically bridging the gap.
“I would very much love to encourage people to come here as tourists and to engage more with Cuba … to promote travel and great relations with Cuba,” she said.
Most U.S. travel to Cuba is barred under Washington’s 51-year embargo against the island, though Americans are increasingly going there on legal cultural exchanges and family visits.
A 32-person support team that includes weather experts and doctors will accompany McCardel on her ocean odyssey, which should last about 55 to 65 hours if she makes it all the way. Every half-hour or so, she plans to pause to eat and down a half-liter of energy drink to stay hydrated.
Special equipment will include an electromagnetic field in the water around her that is designed to keep sharks at bay.
According to her Web site, McCardel has made six solo crossings of the English Channel, two double-crossings in 2010 and 2012 and won the 28.5-mile Manhattan Island Marathon Swim in 2010.
She’s been training for the Havana-Key West swim for the last six months, averaging about 37-56 miles (60-90 kilometers) a week.
McCardel said a key to fighting through long-distance swims is focusing on her stroke in an almost meditative way, and remembering those who have supported her back home and around the world.
“I need to think very positive, uplifting thoughts,” she said. “I’m going to be imagining the finish, imagining how amazing and happy I’ll be walking to shore, visualize the people being around ... really being in the moment. So that’s a positive thing that I use as a goal to work towards.”
McCardel is also swimming to raise money to support cancer research, people who suffer from the disease and their families, and promoting the idea that an active, healthy life can help keep it at bay.
She’s dedicating the swim in part to her mother, a breast cancer survivor.
“But also other people out there who have cancer,” McCardel said, “or have relatives or friends going through that process, or who’ve passed away from that disease.”
