Since the dawn of sports, women were told they couldn't perform and compete as men. The first modern Olympic Games, held in 1896, featured only men's events. Women’s disciplines weren’t added to the athletics program until the ninth edition of the Games, 32 years later. And yet, doing most of the 20th century, women were barred from track and field disciplines longer than 800m based on deeply fallow medical theories and social prejudices. For a long time, the medical community claimed that long-distance running could damage women’s reproductive health and physical wellbeing.
It took decades for women’s athletics events to reach parity with men’s. The first women’s Olympic marathon wasn’t held until 1984. Disciplines like the triple jump, pole vault, and hammer throw were not added to major athletic competitions until the 1990s. Pole vault, for example, was not included in the Olympic program until 2000—104 years after men first competed in it.
In other sports, women faced equally arbitrary barriers. In the early 1900s, Olympic officials only allowed women to compete in "ladylike" swimming events, claiming longer distances could harm their health—remarkably, the women's 1500m freestyle wasn't added until 2020. Football has an equally troubling history: despite women's matches drawing crowds of up to 53,000 during World War I, the English Football Association banned women from Football League grounds in 1921, declaring the sport "quite unsuitable for females"—a ban that lasted 50 years. Even in recent history, women ski jumpers were barred from the Winter Olympics until 2014, despite having competed internationally since the 1990s, with one Olympic official claiming as late as 2005 that the sport was medically "inappropriate" for women.
For decades, pseudoscientific claims about "limited energy reserves," "fragile hearts," and endangered reproductive health masked deep-seated gender biases in sports. Doctors warned that women's bodies would fail and their vital energy would be depleted by athletic pursuits. Yet in the face of these restrictions, remarkable women dared to prove them wrong. These pioneers didn't just compete—they excelled, shattering records and challenging fundamental assumptions about female capability. From marathon runners who raced without official numbers to tennis champions who demanded equality in sports and life, each victory carved a path for future generations. Through their courage and persistence, these groundbreakers demonstrated an essential truth: the only real limits were the artificial barriers placed in their way. Here are their stories of defiance, determination, and triumph that forever changed the landscape of sports.
Lina Radke
Lina Radke was a pioneer in women’s middle-distance running, proving that women could compete at longer distances despite widespread skepticism. At the 1928 Amsterdam Olympics—the first Games to include women’s track events—she won gold in the 800 meters, setting a world record. Though her victory was historic, officials controversially removed the event from the Olympics until 1960, claiming it was too grueling for women. Radke’s performance challenged these misconceptions and helped pave the way for the inclusion of longer races for female athletes.
Althea Gibson
Althea Gibson’s debut at the US National Championships on August 25, 1950, marked a groundbreaking moment for racial and gender equality in sports. Until then, African American players had been excluded from America’s premier tennis event due to segregation. Just as Jackie Robinson broke the color barrier in baseball, Althea Gibson did the same in tennis. Her entry was far from symbolic—Gibson went on to win 11 major titles, including the French Open, Wimbledon, and the US Open. It wasn’t until 43 years later, when Serena Williams won the 1999 US Open, that another African American woman claimed a major singles title.
Wilma Rudolph
Wilma Rudolph overcame polio as a child to become one of the greatest sprinters in history. At the 1960 Rome Olympics, she became the first American woman to win three gold medals in a single Games, dominating the 100m, 200m, and 4x100m relay. Her electrifying speed and grace made her a global icon, challenging gender and racial barriers in sports. Beyond the track, she used her fame to advocate for civil rights, refusing to attend segregated events in her honor.
Bobbi Gibb
It’s one of the most iconic stories in marathon history. In 1966, Bobbi Gibb became the first woman to run the Boston Marathon, defying the rules of the time—women were banned from entering the race, and Gibb started without an official bib. Her bold act of defiance not only challenged societal stereotypes but also helped pave the way for women’s inclusion in marathons. Just six years later, in 1972, Boston officially welcomed female runners.

Flo Hyman
Flo Hyman was a trailblazer in women’s volleyball, known for her powerful spikes and relentless advocacy for gender equality in sports. As the captain of the U.S. women’s volleyball team, she led them to a silver medal at the 1984 Los Angeles Olympics, bringing global attention to the sport. Standing 6'5", Hyman’s dominance on the court revolutionized volleyball, proving women could be both powerful and graceful athletes. Off the court, she fought for strengthening the break-through 1972 US legislation that prohibited sex discrimination by athletic programs in universities that receive federal funding. Her sudden passing in 1986 due to undiagnosed Marfan syndrome cut her career short, but her impact continues to inspire generations of players.
Courtney Dauwalter
Over long distances, women’s endurance has the potential to surpass that of men. Ultrarunner Courtney Dauwalter is shattering stereotypes, showing that women can compete at the highest levels alongside men and redefine the limits of human endurance. In 2023, she made history by becoming the first person ever to win the most prestigious and grueling ultra-trail races in the world in the same year, with groundbreaking victories at the Western States 100, Hardrock 100, and Ultra-Trail du Mont-Blanc.
Ruth Chepngetich
Kenya’s Ruth Chepngetich redefined the limits of marathon running at the 2024 Chicago Marathon, shattering the world record with a stunning 2:09:57—nearly two minutes faster than the previous mark. That day, only 10 men in the elite field finished ahead of her. According to World Athletics scoring tables, which compare performances across disciplines and genders, her time equated to a 1:59:37 men’s marathon. In a way, women have already broken the sub-2-hour barrier.
