In 1967 Kathrine Switzer was a 20-year-old college student. Women weren't allowed to run the Boston Marathon back then because of some nonsense about women's bodies not being able to handle it. But Kathrine wasn't taking no for an answer so she registered under the name "K.V. Switzer".

The photo on the left is an official trying to rip off her bib two miles into the race back in 1967. Her boyfriend shoved him away and she was able to complete the race in 4 hours and 20 minutes.

Here is a video of her running by that exact spot during the race yesterday:

 

According to the NY Times, She wore the same bib number that she wore in 1967 which was 261. And that will be the last time anyone will wear that number. They announced they will be retiring it after the race.
