First Female in the Boston Marathon
On April 19, 1967, 20-year-old Kathrine Switzer made herstory when she became the first woman to officially run in the Boston Marathon, even as race officials tried to physically stop her. She signed her entry form “K. V. Switzer” to obtain a number. By her own estimate, Switzer finished the race in 4:20:00. You can't catch me!
