In 1967, Kathrine Switzer was the first woman runner in the Boston Marathon, a men's only competition for 70 years.
I'm going to finish this race on my hands and my knees if I have to because nobody believes I can do this. And suddenly I realize if I don't finish this race, then everyone's going to believe that women can't do it.... I've got to finish this race.
This was going to change my life, and it was probably going to change women's sports.
