Diana Nyad is defending her 110-mile swim from Cuba to Florida to skeptics who question whether she got into or held onto a boat during the journey.
The 64-year-old endurance athlete held a conference call Tuesday evening with some members of the marathon swimming community. Some say they're suspicious about long stretches of the 53-hour swim where Nyad appeared to have either picked up incredible speed or to have gone without food or drink.
Nyad says she swam without holding onto any of the boats or people accompanying her. She says her team made the swim "in squeaky-clean, ethical fashion."
Evan Morrison of the online Marathon Swimmers Forum says it will be interesting to compare observations made by Nyad's navigator with publically available data about the currents Nyad swam.
