Women In The Boston Marathon
Until 1972, women were not allowed to race in the Boston Marathon. It all started in 1967, when Kathrine Switzer enrolled in the marathon, but the race official, the notorious Jock Semple, tried to take her number away during the race, as can be seen in the photo.
Her boyfriend, who was racing too, stopped him and she managed to finish the race. It still took another 5 years to finally allow women to race officially.
