She didn’t know it at the time, but a photograph of Kathrine Switzer running in the 1967 Boston Marathon would become an iconic image for sports and women’s equality.
The image showed Switzer, No. 261, in the middle of several men, as a race official attempts to pull her off the course. Switzer’s boyfriend, however, shoved the official out of the way, and she ran on to finish.
Since then, Switzer has devoted her life to motivating and empowering women in sports. In 2015, she founded 261 Fearless, a global non profit organization that encourages women through running.
