KEY WEST, Fla. U.S. endurance swimmer Diana Nyad's completed a historic Havana-Key West swim on her fifth attempt, 35 years after her first try.
The 64-year-old Nyad stepped ashore in Key West on Monday just before 2 p.m. EDT, about 53 hours after she began her swim in Havana on Saturday.
As she approached the shore, spectators surrounded her in the water, taking pictures and cheering her on. She swam within a couple dozen feet of the beach and walked on to dry land. She looked dazed and sunburned.
Once on the beach, she was put on a stretcher and received medical treatment, including an IV. Her lips were swollen. CBS News' Elaine Quijano reports she was treated at a hospital and released Monday evening.
"I have three messages. One is, we should never, ever give up. Two is, you're never too old to chase your dream. Three is, it looks like a solitary sport, but it is a team," she said on the beach.
"I have to say, I'm a little bit out of it right now," Nyad said. She gestured toward her swollen lips, and simply said "seawater."
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.
Around 11 a.m. on Monday, mere miles from Florida, Nyad called her support boats over and said she had "bad abrasions" in her mouth from her jellyfish-protection mask, according to her team.
While treading water, she said: "I am about to swim my last two miles in the ocean. This is a lifelong dream of mine and I'm very very glad to be with you. Some on the team are the most intimate friends of my life and some of you I've just met. But I'll tell you something, you're a special group. You pulled through; you are pros and have a great heart. So let's get going so we can have a whopping party."
In an online update posted before dawn Monday, her team said "Diana is on course to swim 112 statute miles. This is 35 more miles than anyone has ever swam."
Her team also claimed that a cruise ship decided to "make way" for her. They posted on Facebook Sunday afternoon that she had "swum farther north than the farthest end point of any of her previous attempts."
On her blog, her medical team reported "Diana's tongue and lips are swollen causing her speech to be slurred. (Her doctors) are concerned about Diana's airways, but have not intervened."
With about 6.5 miles to go, Nyad was contacted by her support team, who were concerned she was cold and in pain. According to her team, she rebuffed offers to replace her swim cap, which fell off during the night, and instead kept swimming.
The 64-year-old has become the first person to swim from Cuba to Florida without a shark cage. It's her fourth attempt in the last three years. She tried three times in 2011 and 2012. Her first attempt was in 1978.
