Swimmer poised for shark challenge
US endurance swimmer Diana Nyad is making final preparations for her bid to become the first person to swim the 103-mile Florida Straits without the aid of a shark cage.
Nyad is spending the day eating, hydrating and meeting with members of her support team ahead of the swim from the Cuban capital Havana to the Florida Keys.
The 61-year-old swimmer will be accompanied by 45 people on five boats during the trip, which is expected to take about 60 hours.
Special equipment will surround her with an electric current that Nyad will not notice, but will keep most sharks at bay. Divers will be at hand to discourage those that get curious.
She expects to depart within a few hours.
