Running was a sport for the men once upon a time, but that notion slowly deteriorated as historical events changed the perception of who could take part. Here are some of those watershed moments that shifted the sport of running toward one of inclusiveness:
1954 — British-born Diane Leather becomes the first woman to run a sub-5-minute mile (4:59.6) on May 29, just 23 days after Roger Bannister ran his 3:59.4 mile. The IAAF didn’t recognize the women’s mile as a world record event until 1967.
1960 — Women are allowed to participate in five running events in the Summer Olympics, including the 800 meters, which had been banned after the race in 1928 because of questions as to whether it was too taxing for female athletes.
1967 — Kathrine Switzer is the first woman to run the Boston Marathon with an official bib registered under the name K.V. Switzer. Although race official Jock Semple tried to pull her off the course, she finished the race in 4:20 and was subsequently banned by the Amateur Athletic Union (AAU).
1972 — The AAU allows women to register for marathons after dropping its 1961 ban on women competing in U.S. road races. However, women are required to start at a separate time. In protest of the “special” start, women sit at the starting line of the NYC Marathon.
1975— After becoming a law in 1972, Title IX begins to got into effect, discouraging unequal federal financial aid and university support for women’s programs. The average number of women’s sports teams for an NCAA school at the time is 2.1.
1978 — Nike introduces first women-specific running shoe, with the Nike Waffle Racer.
1983 — After being unable to compete in the 1980 Summer Olympic Games due to the U.S. boycott, Mary Decker Slaney wins gold medals in the 1,500-meter and 3,000-meter runs at the inaugural IAAF World Track & Field Championships in Helsinki, Finland.
1984 — Joan Benoit Samuelson of the United States wins the first women’s Olympic marathon, held in Los Angeles. She broke away from the pack just 14 minutes into the race and never looked back.
1985 — Great Britain’s Zola Budd breaks the world record in the 5,000-meter on the track running barefoot for the second time in three years with a 14:48.07 effort.
1987 — Jackie Joyner-Kersee becomes the first female runner to grace the cover of Sports Illustrated. The cover line next to her photo reads: “Super Woman.”
1988 — Norway’s Grete Waitz wins the New York City Marathon for the ninth time (a record that still stands).
1991 — Susan G. Komen’s Race for the Cure debuts the first pink ribbon at its NYC event. The now-iconic symbol for breast cancer awareness was given to all breast cancer survivors and participants of the race.
1994 — TV talk show host Oprah Winfrey crosses the finish line at the Marine Corps Marathon in Washington, D.C. in 4:29:15. Her effort, which included her losing 80 pounds in the year leading up to the race, sparked a new running boom among women, with the theme of “anyone can do it.”
1996 — Russian middle-distance runner Svetlana Masterkova sets (and still holds) the women’s mile world record of 4:12.56 at a race in Zurich, Switzerland just a few weeks after becoming the second woman in history to win Olympic gold medals in the 800- and 1,500-meter events.
2002 — Ultrarunner Pam Reed wins the Badwater Ultramarathon, a grueling 135-mile course through Death Valley in the middle of July when temperatures peak at 120 degrees. She beats both men and women enter in the race and repeated the feat in 2003, when she beat legendary ultrarunner Dean Karnazes.
2004 — Nicole Deboom founds Skirt Sports after winning Ironman Wisconsin in the prototype of what would become the original Race Belt skirt. Her brand has continued to change women’s go-to race-day outfits around the world.
2007 — British runner and marathon world record-holder Paula Radcliffe wins the New York City Marathon 10 months after giving birth to her daughter, inspiring mother-runners all over the world.
2009 — Women’s Running publishes its first issue and is now the largest women-specific running magazine in the world.
2012 — Shalane Flanagan, Desiree Davila (now Linden) and Kara Goucher finish 1-2-3 at the U.S. Olympic Trials Marathon in Houston. It was the first time the top three finishers ran sub-2:30 in the trials.
2013 — High school running prodigy Mary Cain of Bronxville, N.Y., finishes second in the 1,500 meters at the USA Outdoor Track and Field Championships, thus becoming the youngest American to represent the U.S. at an IAAF World Championships meet. She became the youngest woman ever to make the finals and wound up placing 10th.
2014 — Shalane Flanagan’s fast early pace at the Boston Marathon sets the tone for the first four finishers to break the course record against the race’s most competitive field in history. Flanagan winds up seventh with the fastest American women’s time in Boston history.
