First woman to complete Boston Marathon (Kathrine Switzer)

Before Kathrine Switzer became a historic figure in women’s sports, as the first woman to formally enter and complete the Boston Marathon and the driving force behind the women's marathon being added to the Olympics, she started running in her backyard in Dunn Loring, on Westchester Drive just west of Gallows Road. And then she ran along a new road then under construction, to be called the Capital Beltway. And then, when it was new and lightly traveled, she ran on the median of the Capital Beltway.
