In 1969, 32-year-old Sara Mae Berman was the first woman to cross the finish line in the Boston Marathon. She did it again in 1970 and 1971. But women weren’t allowed to enter officially, so her times—3:22:46, 3:05:08, and 3:08:30, respectively—were unofficial. "All we ever wanted, us early women, was to be allowed to run the distance, and we weren't in any bloodthirsty competition with each other. We just wanted to be able to run the distance and improve our times," she says.
