On April 19, 1897, the first Boston Marathon is run in Boston, has been held every year since then, even during the World War years.

Kathrine Switzer was the first woman to run the Boston Marathon with a registered number 261 in April 19, 1967, when women weren't allowed to run. When a race official named Jock Semple saw that she was running with a number, he tried to physically remove her from the race and rip her bib number off. Her boyfriend, Tom Miller, knocked Semple away so Kathrine Switzer could keep running.

Finally, five years later, in 1972, women were officially welcomed to run the Boston Marathon for the first time.
