KEY WEST, Fla. - U.S. endurance swimmer Diana Nyad's representatives say she's making good progress on the second day of her Cuba to Florida swim.
Her team posted on Facebook Sunday afternoon that she had "swum farther north than the farthest end point of any of her previous attempts."
During feeding earlier, Nyad mentioned pressure in her lungs. Doctors checked her vitals and reported that her blood pressure was normal and her lungs were clear.
She made it through her first night in the Straits of Florida with almost no sightings of jellyfish.
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.
