MIAMI (AP) — Diana Nyad's swim from Cuba to Florida has generated some skepticism in the small community of marathon swimmers.
Critics have suggested that during a speedy stretch of the 53-hour swim, Nyad might have gotten into or held onto the boat that accompanied her.
They also question whether she violated the traditions of her sport by relying on a specialized mask and wetsuit to protect herself from jellyfish.
According to Nyad's team, she finished the 110-mile swim Monday afternoon in Key West, becoming the first to do so without the aid of a shark cage.
Nyad's navigator and one of the swim's official observers tell The Associated Press that Nyad didn't cheat. Navigator John Bartlett says the 64-year-old endurance swimmer got a boost from the fast-moving Gulf Stream, but nothing more.
