This is Katherine Switzer. She was the first woman to run a marathon. Because marathons were strictly for men in those days, when she signed up she just wrote KV Switzer. When this judge saw it was a female he ran to grab her and make her stop...the male runners wouldn't let him. Kudos to her and to the runners who stood up for her. As a person who loves to run and has run in races...this makes me thankful I am allowed to do it!
