HAVANA (AP) - Endurance athlete Diana Nyad is preparing for a second attempt to swim from Cuba to Florida and set a world record at the age of 62.
    
Nyad plans to set out from the Hemingway Marina in Havana on Friday evening. She is spending the day meeting with her support team, loading up on carbohydrates and loosening up. She's hoping to take advantage of current favorable sea and weather conditions.
    
The Los Angeles woman fell short in a previous attempt at the swim last month, calling it off after 29 hours in the water and about halfway through the 103-mile (166-kilometer) journey. She said then that there would be no repeat.
    
Nyad said Friday: "Don't listen to athletes when they say it's over."
