Long-distance swimmer Diana Nyad will directly confront skeptics and their claims that she was dishonest about her record-setting swim from Cuba to Florida at a closed-door meeting on Tuesday, her spokeswoman said.

"She is committed to complete transparency," Nyad's spokeswoman, Alexandra Crotin, said today in a statement.

Crotin did not answer questions about details of the meeting, including where and when it was taking place and who planned to attend.

Nyad, 64, and her 110-mile swim became the subject of debate last week among members of MarathonSwimmers.org, a members-only forum for distance swimmers. Critics on the site have been examining stroke speed, currents and other factors to determine whether Nyad was telling the truth about the September 2 swim. Critics say they are also skeptical about the speed with which she completed the journey and a 7-hour stretch in which she did not stop to eat.

The website did not respond to ABC News' request for comment.

Nyad's team told the Associated Press that swift currents aided Nyad and helped her increase her speed during part of the swim.

Nyad said at a press conference last week that she was surprised at how fast the swim went. Her best friend, Bonnie Stoll, told her that she was on pace to arrive in Key West, Fla., a day earlier than planned.

"I said, 'What about Monday night?' and she said. 'You're not going to be swimming Monday night,'" Nyad said, standing up and pounding her chest with her hand. "All that trepidation I was feeling just rose up and now we were going again, now we're going."
