1966 - Bobbi Gibb

Although not an official entrant, Roberta “Bobbi” Gibb became the first woman to run the Boston Marathon. Joining the starting field shortly after the gun had been fired, Gibb finished the race in 3:21:40 to place 126th overall. Gibb again claimed the “unofficial” title in 1967 and 1968.
