"Diana Nyad is now facing backlash over her record-breaking 110-mile swim from Cuba to Florida as other members of the small community of marathon swimmers are questioning whether she cheated."
On social media and the online Marathon Swimmers Forum, long-distance swimmers have been debating whether 64-year-old Nyad got a boost from the boat that was accompanying her - either by getting in it or holding onto it - during a particularly speedy stretch of her swim.
'When you know how hard it is, you kind of want those details,' said Andrew Malinak, a Seattle long-distance swimmer who crunched the data available from the GPS positions tracked on Nyad's website and concluded that he didn't trust what he saw.
Nyad's navigator and one of the swim's official observers told The Associated Press this weekend that Nyad didn't cheat and that she was aided during the rapid part of her swim by a swift current.
