How Kathrine Switzer's history-making move in 1967 led to a career advocating for women in sports.
When Kathrine "K.V." Switzer took her place at the starting line of the 1967 Boston Marathon, wearing a bulky, grey sweat suit and lipstick, she was about to make history. No woman had ever officially entered and run the venerable race before, although she had heard that a woman ran it the previous year without a bib number. Switzer had been training hard with her coach, Arnie Briggs, at a time when it was widely believed that women simply didn't have the physical capability of running the 26.2 miles that make up a marathon.
