Today is the world-famous Boston Marathon. It is a good time to remember Kathrine Switzer.

Kathrine Switzer was the first woman to enter the Boston Marathon, in 1967. She applied to run by using her initials instead of her first name.

For the previous 70 years, the famous marathon was open to male athletes only.

She ran with her coach and her boyfriend alongside her. They were both students at Syracuse University.

When race officials realized there was a woman running, they tried to drag her out of the race and rip the numbers off her back.

Her boyfriend pushed the older men out of the way, so that Kathrine could continue.

She was asked by the press, “Are you a suffragette? Are you a crusader?”

She said, “No, I am just trying to run.”
