Endurance swimmer Diana Nyad is slowly churning closer to land on her fourth straight day to become the first person to swim from Cuba to Florida without a shark cage.
Nyad had been expected to arrive somewhere in the Florida Keys early Tuesday morning. If she makes it there on Wednesday, it with be her 63rd birthday. During the overnight hours, Nyad's team tweeted that she has completed 59.9 miles, leaving her just over 40 miles to go.
Nyad survived her third harrowing night in the water while her lips and tongue continued to swell, puffing up due to the salt water. She's also battling the pain from searing stings of jellyfish as she has been stung at least four times already. Those same jellyfish stings sunk her hopes during her journey to this feat last year.
On Monday, Nyad and her crew were worried about shark infested waters. Luckily no sharks were seen and the swimmer's spirits were lifted by a surprise visit from a boatload of friends and family, according to The Associated Press. Monday evening, she found herself swimming among dolphins.
It is Nyad's third attempt to complete the swim in less than a year. For the record to count, she is not allowed to touch or be touched by any of the support crews or vessels. She is also not allowed to sleep while trying to make the swim. While Nyad continues to swim, she is burning about 30,000 calories and must eat tubes of peanut butter every 90 minutes.
Nyad ended her last attempt in September 2011 after more than 40 hours, 67 nautical miles of swimming, and two Portuguese Man-of-War stings.
