Photo Gallery: Groundbreaking runner Kathrine Switzer speaks at UCI

Kathrine Switzer, 70, addresses her audience at UC Irvine on Thursday. Her shirt bears the name of 261 Fearless, a nonprofit she founded in 2015 to unite women through the creation of running clubs, educational programs, communication platforms and social events. She wore the number 261 in the 1967 Boston Marathon.

Photos from the Boston Herald show a director of the 1967 Boston Marathon trying to remove Kathrine Switzer, the first official female entrant in the race. Switzer’s boyfriend at the time, “Big Tom” Miller, intervened and she finished the race.
