Open water swimmer Diana Nyad is back in Key West, Florida, continuing her quest to be the first person to make a 103-mile swim from Havana, Cuba to Florida without a shark cage. A Yahoo! News team recently accompanied Nyad on a grueling 9-hour training swim, shooting an episode of the award-winning show Second Act from aboard her escort vessel. Nyad, who is 61 and swims around 1.5 miles an hour,  is waiting for favorable water temperatures and ocean wind speeds to attempt the 60-hour crossing.  Hurricanes and delays with Cuban visas prevented her from trying the swim last summer.  Click here to see the video.
