Kathrine Virginia "Kathy" Switzer

In 1967, she became the first woman to run the Boston Marathon as a numbered entrant. During her run, race official Jock Semple attempted to stop Switzer and grab her official bib; however, he was shoved to the ground by Switzer's boyfriend, Thomas Miller, who was running with her, and she completed the race. It was not until 1972 that women were allowed to run the Boston Marathon officially.
Because of her run, the Amateur Athletic Union (AAU) barred women from all competitions with male runners, with violators losing the right to compete in any races.
Switzer, with other women runners, tried to convince the Boston Athletic Association to allow women to participate in the marathon. Finally, in 1972, women were officially allowed to run the Boston Marathon for the first time.

This woman, had the courage that many did not have in those times where they were oppressed by a culture that gave the advantage to man
she set a great example for women of all ages, thus marking a change and breaking the barriers of sexism.
