When she looked ahead, Florence Chadwick saw nothing but a solid wall of fog. Her body was numb(全身麻木). She had been swimming for nearly sixteen hours. Already she was the first woman to swim the English Channel in both directions. Now, at age 34, her goal was to become the first woman to swim from Catalina Island to the California coast.
On that fourth of July morning in 1952, the sea was like an ice bath and the fog was so dense she could hardly see her support boats. Sharks cruised toward her lone figure, only to be driven away by rifle shots. Against the cold sea, she struggled on ---- hour after hour ---- while millions watched on national television.
Alongside Florence in one of the boats, her mother and her trainer offered encouragement. They told her it wasn't much farther. But all she could see was fog. They urged her not to quit. She never had … until then. With only a half mile to go, she asked to be pulled out.
She told a reporter hour later, Look, I'm not excusing myself, but if I could have seen land I might have made it. It was not tiredness or even the cold water that defeated her. It was the fog. She was unable to see her goal.
Two months later, she tried again. This time, despite the same dense fog, she swam with her goal clearly pictured in her mind. She knew that somewhere behind that fog was land and this time she made it! Florence Chadwick became the first woman to swim the Catalina Channel, eclipsing(超出) the men's record by two hours!
