Diana Nyad Makes Another Attempt to Swim From Cuba to Florida

Diana Nyad is trying another attempt to swim from Cuba to Florida after failing to reach her goal in August.

The 62-year-old endurance swimmer from Los Angeles said she's ready for the planned 60 hour. Journey  began in Havana Friday night.

Nyad said, "I'm prepared and even saying that though, how many times do you get to do something of this big an adventure? You know, how many times do you get to feel this alive? This awake and alive?".

Last attampt was ended due to an asthma attack in last month after 29 hours in the water. She was 15 mph off course due to strong currents, according to Tweets on her page at the time.

Nyad is hoping to improve her own world record for open-water swimming without a shark cage. Australian swimmer finished a swim from Cuba to the Keys in 1997 but used a cage.

If she completes the swim, she will break her 1979 record, where she swam 102.5 miles from the Bahamas to Florida.

"I am confidence at 62 than I was at 28, which is the first time I tried this, 28 years old. She said I am not fast as I was in 1979.

Her spotters cheered Nyad on as she began her swim Friday.

"I know I'm going to be cold," Nyad told the Associated Press. "I know I'm going to run into all kinds of jellyfish and the nights are going to be long."

On Nyad's twitter account, her assistants have been updating the public of the swimmer's progress.

At one point, it appeared she was stung by a moon jelly.
