"When I was young, women just didn't play sports," Bergen says. "Now I'm making up for lost time." Bergen began racing nearly 20 years ago when her husband told her, "Anyone can run."

"Some of the women I race are chatty," says the La Caņada Flintridge, Calif., resident. "But I'm not at the starting block to make friends."
