Janet Evans, Gold Medal Swimmer, Trains For Olympics At Age 39 (VIDEO)

If Janet Evans is unsure of herself, she doesn't show it.

The 39-year-old Olympic champion and world record holder has begun training in Huntington Beach, Calif. with the goal of qualifying for next year's U.S. Olympic trials. So far, she is confident she'll be able to take on the younger competition.

"Who knows what will happen," Evans tells the AP. "It was kind of something that I always wanted to do, but I needed the courage to do it."
