Author, journalist, former TEDMED speaker, and long-distance swimmer Diana Nyad has broken numerous world records. Her swim around Manhattan (under eight hours) and the 102 miles she swam in open waters from the Bahamas to Florida were her biggest swimming achievements by age 30. In 2013, Diana attempted, for the fifth time, the 110-mile ocean crossing between Cuba and Florida. With a strong team and a new commitment to her vision, she became the first person to swim the distance without a shark cage.
