Here's a look at how women have made history, in the running world, over the past five decades.
Women are allowed to participate in five running events in the Summer Olympics held in Rome--as opposed to the 16 races open to men. After being banned for 32 years due to medical concerns that the event was too taxing for the "frail" female gender, the women's 800 meters is reintroduced. Soviet Union runner Irina Press wins the race, while sister Tamara gets gold in the shot put. Western journalists dub the two women "the Press brothers."

The Amateur Athletic Union (AAU) bans women from competing officially in all U.S. road races. Nineteen-year-old runner Julia Chase enters a 6.5-mile road race in Chicopee, Massachusetts, in an attempt to challenge the ban. While her run garners media attention, her plight is largely regarded as a spectacle. New York Journal American writes: "Miss Chase said she is 5'4 ½", weighs 118 pounds and does not know her other dimensions. (Eyewitnesses report her other dimensions are very good.)"
Kathrine Switzer runs the Boston Marathon with an official bib by registering under the name K.V. Switzer. Race official Jock Semple attempts to pull Switzer off the course mid-race, but is body blocked by Switzer's boyfriend. Switzer finished the race in 4:20 and is subsequently banned from the AAU.
The AAU allows women to register for marathons, but they are required to start at a separate time or starting line than men. In the 1972 New York City Marathon, women refuse to subscribe to the "special" start, and sit down for 10 minutes at the starting line until the men's gun goes off.
