Critics have knocked Nyad for withholding a detailed account of each of her nearly 53 hours in the ocean, information that would include her speed, the number of strokes, her feeding schedule, and her Global Positioning System coordinates—standard data recorded by observers that would bolster her claim.
"If she's accomplished what she's claiming to accomplish … I wonder why she wouldn't take the extra steps to make sure people believe it was actually true," Morrison said.
The lack of information is particularly irksome to some swimmers because Nyad's team has produced a steady stream of pictures and blog posts for publicity, but not the specifics that her fellow sportsmen crave. "I'm skeptical if she swam every stroke of that 110 miles,'' said Mo Siegel of Piermont, New York, who just completed a 20-mile crossing of Cape Cod Bay. "I'd love to be proved wrong."
