Kathrine Switzer, who was the first official woman entrant in the Boston Marathon 50 years ago, crosses the finish line in the Boston Marathon, Monday, April 17, 2017, in Boston.
He eventually began training for various athletic events, and ran in the Marine Corps Marathon.
Inspiration is synonymous with the Boston Marathon, but one participant's incredible run captured attention on social media. She won the New York City marathon in 1974. "You might not run a lot of 5 and 10Ks on the track but you've got to have the ability to do it".
Switzer finished anyway, and came back eight more times.

This will be the last time anyone wears bib number 261, as officials have retired the number in honor of Switzer.
Monday's race also served as a point of reflection for Switzer.
The warm temperatures that hit 79 degrees at the 20-kilometer mark in Natick slowed the runners, but the strong tailwind was a boost - especially in the wheelchair races.
Marcel Hug won Boston for the third time, outpushing 10-time champion Ernst Van Dyk down Boylston Street and finishing in 1:18:04 to beat the course record and world best by 21 seconds. "Everything was fantastic today".
Other top men's contenders include Kenya's Emmanuel Mutai, who won the 2011 London marathon, Ethiopia's Yemane Tsegay, who finished third in Boston in 2016, with the top American contender Galen Rupp of Portland, Oregon, fresh off a bronze in the Olympic marathon in Rio de Janeiro. Evans, who completed his 52nd marathon overall, said he wanted to show that Boston is back to normal.
