Watch Kathrine Switzer Cross the 2017 Boston Marathon Finish Line

When Switzer ran in 1967, she was 20, and entered as "K.V. Switzer" - so none of the race organizers would know she was a woman.

"The marathon was a man's race in those days; women were considered too fragile to run it", she wrote in an essay for The New York Times 10 years ago.

Switzer ran the marathon wearing the number 261, the same number male participants had tried to rip off her clothing in 1967.

"He inspired me to completely not only change my life, but to change millions of women's lives". Other runners helped Switzer bat off the race official, and she went on to finish the marathon. And she competed in Boston several more times, placing second in the women's race in 1975 with a time of 2:51, her personal best. While she was running, the race director attempted to physically remove her from the race. New records were set for both wheelchair races, with Swiss racer Marcel Hug taking home the win for the men at 1:18:04, and Manuela Schar, also of Switzerland, winning for the women with a time of 1:28:17.

In the clip, Granville - of Carbondale, Pennsylvania - is seen hoisting his race partner on his back and carrying her to the end of the race.

"And when he came to, he was so impressed", she said.

As the years went on she advocated for women to be admitted as full competitors - and kept running more and more marathons.

"He said, 'No dame ever ran no marathon, '" she said. "I just hope my good time today wasn't just because of the tailwind".

"Oh my gosh, hands up in the air, big grin across my face you would have thought i won the race I was so elated and then I bent down and started crying", said Kaplan. But anytime I doubted myself, the crowd wouldn't let me stop.

A little over one mile in, Switzer took a live video at the infamous spot where she was attacked during her first Boston Marathon. "What a way to start the race".
