Diana Nyad says big swim is Sunday

The big moment is here, distance swimmer Diana Nyad says. On Saturday she tweeted, "It's my time to be fearless."If all goes according to plan, late Sunday or early Monday she'll begin her attempt to set a world record, swimming in the open water, without a shark cage, from Cuba to Key West, Florida. It's 103 miles; she expects it'll take at least 60 hours.

CNN is the only network accompanying Nyad, 61, on her swim. We'll be at  Nyad's Havana news conference on Sunday, then board one of Nyad's chase boats, and keep you up to date in real time or close to it.
In 1978, Nyad attempted this same swim. After just over 40 hours in the water, her team pulled her; high waves and strong currents had pushed her too far off course.  That experience has driven her toward this swim.  "Visions of 1978, those smashing 8-ft seas, flash through my brain. Not this time. Strong memories of the hardships of these past two years make me strong and determined not to waste all that disciplined time put in," she wrote in her blog Saturday.
