Kathrine Switzer was a 20-year-old college student when she registered to run the 1967 Boston Marathon, her first marathon. Early in the race, race director Jock Semple charged onto the course and tried to physically rip off her bib number and remove her from the competition. Kathrine’s boyfriend pushed him out of the way and despite taunts from media to quit because she was female, Switzer finished the race, creating a lasting moment in women's history.
