After Monday, no one will wear that number in the Boston Marathon again. A few miles into the run, Semple chased down Switzer and attempted to take away her official race number. Boston Marathon official Jock Semple tries to eject Kathrine Switzer (261) in 1967, but Tom Miller runs interference and blocks him out. She went on to become an accomplished marathon runner, winning the 1974 New York City Marathon and finishing second in the 1975 Boston Marathon. Monday will be her first time running the Boston Marathon since 1976.
