For almost 40 years, Kathrine Switzer, one of sports' greatest legends, has been a leading authority on running and women's health. She is best known for paving the way for women's participation in marathons, beginning with her historic run in the formerly all-male Boston Marathon in 1967. She went on to become a world-ranked athlete and the 1974 New York Marathon winner. Switzer is an Emmy-winning television commentator who has covered a long list of major sporting events, including marathons in Boston, New York, Pittsburgh, and Los Angeles, as well as the Olympic and Goodwill Games. Almost 100,000 copies of her first book, Jogging and Walking for Women Over 40, have been sold. She currently resides in New Paltz, New York.
