swimming as a sport and was a Florida State High School swimming champion. Like
many young athletes, she had Olympic dreams, but a serious illness kept her
from competing in the Games. The disappointment didn’t stop her from going
forward. Instead, she became interested in marathon swimming. A brilliant
athlete, she was well-conditioned for spending long periods of time in the
water. As a long-distance swimmer, she would compete against herself and the obstacles
presented by distance, danger, cold, and exhaustion.
For ten years Nyad devoted herself to becoming one of
the world’s best long-distance swimmers. In 1970, she swam a ten-mile marathon in
Lake Ontario, setting the women’s record for the course. In 1972 she set
another record by swimming 102.5 miles from an island in the Bahamas to the
coast of Florida. Then she broke a third record when swimming around Manhattan
Island in 1975.
Nyad attempted to swim the distance between Florida
and Cuba in 1978. Though the span of water is less than 100 miles wide, it is
rough and dangerous. After battling the water for two days, she had to give up
for the sake of her own health and safety. Even so, she impressed the world
with her courage and strong desire to succeed. For Nyad her strength of purpose
was just as important as reaching Cuba. That is how she defined success. It did
not matter that her swim came up short; she believed she had touched the other
shore.
When Nyad ended her career as a swimmer, she continued
to try new things---travelling the world as a reporter, writing books and
giving public speeches about her life. Diana Nyad works to inspire others, just
as she did when she swam the waters of the world.
