50 years after becoming the first official female to run in the #BostonMarathon, now 70-year-old #KatherineSwitzer completed the 121st running of the storied distance race on #PatriotsDay. Switzer ran with the race number 261 - the same number on the bib that a disapproving race official famously tried to rip from her sweatshirt in 1967 | 📷: bostonglobe | #GettySport
