Lynne Cox started swimming almost as soon as she could walk. By age sixteen, she had broken all records for swimming the English Channel. Her daring eventually led her to the Bering Strait, where she swam five miles in thirty-eight-degree water in just a swimsuit, cap, and goggles. In between those accomplishments, she became the first to swim the Strait of Magellan, narrowly escaped a shark attack off the Cape of Good Hope, and was cheered across the twenty-mile Cook Strait of New Zealand by dolphins. She even swam a mile in the Antarctic.
