Nyad trying again for swim record

CNN  told the story of Diana Nyad's milestone August swim  in an  hourlong documentary last weekend, Diana Nyad: Xtreme Dream.

On Friday night, Nyad began yet another chapter, jumping into the water in Havana, Cuba, trying once more to set a distance record for open-water swimming without a shark cage.

Friday night, she was stung multiple times by a Portuguese man-of-war, according to her blog, and on Saturday morning, the blog said, she was struggling in the water, believing she was not getting adequate oxygen to her muscles.

Just before 9 a.m. Saturday, her handlers tweeted that she was  about 25 miles off Cuba. Her team expects the 100-mile-plus swim will take as long as 60 hours.

In the August attempt, she was pulled her from the water after almost 29 hours.
