( CNN ) -- After dodging sharks and jellyfish during her swim from Cuba to Florida , Diana Nyad is now dealing with a different challenge : tough questions from her fellow marathon swimmers about the legitimacy of her achievement . In the days since Nyad walked out of the water last week at Key West after swimming 110 miles , a stream of questions has come at her . Could her speed have nearly doubled at one point ? Did any of her team members touch her or support her ? How could she have gone for hours without food or water ? The questions are significant because the answers could determine whether Nyad is officially affirmed as the first person to have completed the Cuba-Florida swim unassisted and without a shark cage . Five thrill-seeking women breaking world records . During a conference call with more than a dozen of her peers Tuesday , Nyad was adamant that her swim was by the book . `` I swam , '' she said . `` We made it , our team , from the rocks of Cuba to the beach of Florida , in squeaky clean , ethical fashion . '' She said she never held onto a boat or another person `` for any kind of flotation or support . '' Her navigator , John Bartlett , described how the team picked up a current that had them moving nearly four miles an hour for several hours on the second day of the nearly 53-hour journey . That 's how and when her speed nearly doubled , he said . Diana Nyad 's jellyfish-proof face mask . 'No handlers ' Asked about reports she had gone for hours without food or water , Nyad said she never went more than 90 minutes . Getting into the suit that protected her against potentially deadly box jellyfish required duct taping her booties and gloves . That meant she was touched , she said , but never supported . There were `` no handlers grabbing my ankles , '' Nyad said . `` I was on my own steam entirely , but I was touched . I agree with it . '' If the group of her swimming peers determines that the suit and the touching mean her swim was assisted , that could nullify her record claim . One marathon swimmer who was on the call was unimpressed . `` She acknowledged that her crew touched her when she was putting on the jellyfish suit , '' said Evan Morrison , a co-founder of Marathon Swimmers Forum . `` And I know she feels that was necessary , but I personally feel that puts in the category of an assisted swim . '' Now , Nyad has to wait to see if the group of her peers agrees with Morrison , or with her . Nyad shows baby boomers so 'not over '
