"If you're losing faith in human nature, go out and watch a marathon."

In the 1928 Olympic games, false reports that women runners were collapsing in the 800m caused the IOC to ban women from running longer than 200m. This ban will be lifted at the 1960 Olympics.

In 1967 the German-born American Kathrine Switzer will enter the all-male Boston marathon, taking advantage of the fact that there was no rule against women, wrote K.Switzer and took the legendary 261 that is still a symbol in women runners.

During the race, she was attacked by a man, a member of the organizing committee, violently trying to pull her off course, a move that was recorded in the media of the time. Her male teammates will support her and Kathrine Switzer will finish the race.

“Leaving the race was not an option for me. I knew if I did they would think women can't run long distances. I didn't let fear stop me"

At the age of 70, she will run again in the Boston Marathon with a time of 4 hours 44 minutes and 31 seconds, wearing the number 261 on her chest.

What happened on the streets of Boston in 1967 changed the lives of many women. Since then Kathrine Switzer has created women's organizations and clubs that promote women's participation in sports.

Boston Marathon number 261 has been retired in her honor.
