Some marathon swimmers are questioning Diana Nyad's record-breaking swim from Cuba to Florida, last week.
They want to know if she really swam all 110 miles unassisted in shark-infested waters.
Or, did she rest on a boat or hold onto a canoe?
The skeptics want her GPS, surface-current, weather, and eating and drinking information released to verify everything.
According to the Chicago Tribune, Nyad will meet, Tuesday, with those who are questioning her. She wants to answer all of their concerns directly.
