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?
