Call her brave, call her stupid... but call her a new record holder.
Diana Nyad because the first person to ever swim from Cuba to Florida without the aid of a shark cage today, arriving on the shore of Key West a bit before 2 p.m. EST.
She took the plunge in Havana, Cuba, 53 hours earlier.
The 64-year-old endurance swimmer first attempted this astonishing aquatic trek in 1978 and three times again in 2011 and 2012 before finally succeeding.
Flanked by boats that supplied her with food and fended off sharks, she swam the entire 110 miles without a protective cage and essentially without stopping.
"I have three messages," a sunburned and swollen-lipped Nyad said.
"One is, we should never, ever give up. Two is, you're never too old to chase your dream. Three is, it looks like a solitary sport, but it is a team."
