    Physical therapist and sports official

    John Duncan Semple (October 26, 1903 – March 10, 1988) was a Scottish-American runner, physical therapist, trainer, and sports official.

    In 1967, as a race official for the Boston Marathon, he attempted to stop the 20-year-old marathon runner Kathrine Switzer from continuing to run and knocked down her coach when he tried to protect her. Switzer was officially entered in the race in accordance with the Boston Marathon's rule book, which at that time made no mention of sex.[1][better source needed] Semple subsequently claimed that amateur rules banned women racing for more than 1.5 miles (2.4 km).[2] He subsequently oversaw implementation of qualifying times in 1970 and, in response to lobbying and rule changes by the Amateur Athletic Union (AAU), the implementation of a separate women's race in 1972.[3]
