Dr. Joan Ullyot, the “fastest physician marathon runner," paved the way for women runners across the world, proving by example that women should not be counted out when it comes to long distances. Ullyot raced in 80 marathons, winning ten of those along with the masters division in the Boston Marathon in 1984. Her book “Women’s Running,” published in 1976, and her in-depth studies as an exercise physiologist made the case that women deserve the equal opportunity to run competitively; her efforts were instrumental in lobbying the International Olympic Commission to add the women's marathon to the Olympics in 1984. Dr. Ullyot passed away in 2021, at age 80; this interview was conducted in 2013 by Amy Begley.
