Kathrine Switzer

Kathrine Virginia Switzer (born January 5, 1947) is an American marathon runner, author, and television commentator.

In 1967, she became the first woman to run the Boston Marathon as an officially registered competitor, having entered as "K.V. Switzer". Switzer's trainer Arnie Briggs, and her boyfriend Thomas Miller, were also in the race. During her run, the race manager Jock Semple assaulted Switzer, trying to grab her bib number and thereby remove her from official competition. Semple knocked Briggs down when Briggs tried to protect her, but Semple was then shoved to the ground by Miller; she completed the race. The attack was photographed and reported internationally.
