Nyad Makes Steady Progress Toward Florida U.S. endurance simmer Diana Nyad's representatives say she's covered about two-thirds of her route from Cuba to Florida. Late Sunday night, Nyad's team tweeted that she had about 32 miles away from Florida. Overall, the swim was expected to be about 100 miles if she's able to complete it. Her team posted on Facebook Sunday afternoon that she had "swum farther north than the farthest end point of any of her previous attempts." The 64-year-old is trying to become the first person to swim from Cuba to Florida without a shark cage. It's her fourth attempt in the last three years. If she's successful this time, she expects to take about 80 hours to reach the Florida Keys.
