UPDATE: At around 2:04 p.m., Diana Nyad, 64, become the first person to swim from Cuba to Florida without a shark cage. The entire trip took her over 54 hours.
The 64-year-old endurance swimmer Diana Nyad is within 5 miles now of becoming the first person to swim the 103 miles from Havana, Cuba to Florida without a shark cage or flippers. CNN reports that the remarkable distance already conquered has taken a toll on the swimmer's body and that at the last meal time Nyad was slurring her speech.
She reportedly passed the mark of 10 miles from to her destination at around 4 a.m. EST Monday morning.
This is Nyad's fifth attempt to make the swim after having tried for the first time at 28-years-old in 1978, then in 2010, 2011, and twice in 2012.
Her team is currently estimating that she will arrive in the Florida Keys between 2 p.m. and 4 p.m. EST. In the meantime however, her team says that she will need to avoid sharks, jellyfish, tides, and ships as she draws closer to her goal.
