When you think about excellence in the marathon, the name Deena Kastor inevitably jumps to mind. After all, the 52-year-old held the American record in the distance for a whopping 19 years, setting it first in London in 2003, then bettering her own mark just three years later when she became the first American woman to run under 2:20. In fact, Kastor—a three-time Olympian, World Marathon Majors champ, World Cross Country medalist, and holder of national records from the 5K up to the 26.2—was drawn to distance from the very first time she hit the track.

Long before Roberta Gibb and Sara Mae Berman unofficially ran the Boston Marathon (1966 and 1969 respectively), Arlene Pieper Stine became the first woman to officially finish a sanctioned marathon in 1959, when she ran the Pikes Peak Marathon—ascent and descent—in 9:50:20 when she was 29. She was accompanied by twelve men and a horse. Pieper Stine ran in the men's category and was not given a special category or fanfare for her historic finish. She never ran another marathon and her pioneering accomplishment fell into obscurity until 2009.

Upon turning 50 years old, Yolanda Holder decided to do something different for her birthday. While others in her circle of family and friends opted for elaborate parties, expensive experiences or trips, or even purchasing long-desired goods, Yolanda, on the other hand, set out to walk 50 marathons in 50 weeks. She didn't just meet that goal—she crushed it, completing 66 marathons in 52 weeks. And she never stopped. Now 67, Holder has become one of the most accomplished ultra-endurance athletes in the world. She has set Guinness World Records, all while breaking barriers as a race walker in a runner's world. Yolanda is also the first African American woman to achieve numerous milestones in multi-day racing.

Nina Kuscsik began running in the 1960s after discovering Bill Bowerman's Jogging while waiting for a bike tire repair. Born in Brooklyn in 1939, she was a natural athlete who became New York State champion in roller skating, ice speed skating, and bike racing in 1960. After taking a break to raise her three children, running reignited her competitive spirit. She unofficially ran the Boston Marathon in 1969 and 1970, then won it in 1972 when it first officially accepted women, finishing in 3:10:26. A pivotal moment came in 1970 when she was turned away from a two-mile race simply for being a woman—an experience that transformed her into a fierce advocate for women's running rights. At the 1972 New York City Marathon, she led a protest against the separate start rule for women, sitting at the starting line until the ban was lifted. During the 1970s, she likely ran more marathons than any other woman, completing over 80 marathons and winning 15. Her advocacy helped establish women's marathon running, and she witnessed Joan Benoit become the first Olympic women's marathon champion in 1984. As her son remembered, despite all her victories and advocacy work, Nina simply "ran for the pure pleasure of it" and loved "the freedom that running gave her."

Lena Hollmann began her running journey in Sweden, her native country. She started with the 800 meters until 1969, when women were allowed to run the 1500 meters as well. She was part of the Swedish National Track Team and was a national champion in the 1500 meters. Lena moved to the United States with her husband in the late '70s and at first, ran for fitness and fun. Then, she began training seriously again, entering races, and seeing success. In fact, she was the top woman at the Philadelphia Distance Run Half Marathon in 1979. Highlights of her running career include her 10th-place finish at the 1984 Boston Marathon and her 2:44:10 at the 1983 New York City Marathon. Lena's elite running career ended when knee problems intervened. She changed focus and became a certified personal trainer and coach. This was the beginning of a new and rewarding journey for Lena. She focuses on women, specifically older women, and helps them achieve their fitness goals and develop a positive self-image. She's even considering a new role … model. "I want to show women that life isn't over because you're in the mid-70s, and there are so many possibilities," she says.

Molly Barker began running with her mother when she was 14 years old, when her mother was newly sober. Years later, it was on a run in 1993 when Molly herself realized she needed to stop drinking or it would kill her. That run inspired her to create a program for young girls to accept who they are, with grace and pride, and celebrate themselves. She launched Girls on
the Run in 1996 at a site in North Carolina with 13 girls; it quickly grew and now has sites in all 50 states and in Canada. Molly left the organization in 2013 and now calls herself a "grandmother" to the organization (she also has two kids and one grandchild). In addition, she's written several books, including Girls on Track: A Parent's Guide to Inspiring Our
Daughters to Achieve a Lifetime of Self-Respect and Healthy Living, which helped bring the
Girls on the Run program into the home.

Say the name Kathrine Switzer and many people aren't sure who she is. Say, "the woman who
was accosted during the 1967 Boston Marathon because she was running in an event for men
only," and it's an image people recognize and remember. Kathrine had no idea what a historic run Boston would be; it became the spark for her life path. She went on to work at Avon and develop Avon Global Women's Running, then advocated to have the women's marathon included in the Olympics. She has also written books, commentated for major races, spoken to groups all over the world, and was the honorary starter for the women's marathon at the Paris Olympics in 2024. Her number in the 1967 Boston Marathon, 261, became an inspiration for women and then the namesake of 261 Fearless, a non-profit Kathrine co-founded in 2015. She continues to open doors for women, encouraging them through running and helping them feel empowered, no matter their circumstances.

Marge Hickman can't sit still. If she's not running, she's hiking, driving around the country in her RV, or engaging in another form of movement. Since she was a kid, the ultra running phenom has always felt an insatiable drive to prove herself. And that drive has taken her places few in the running community have dared to go. In 1989, Hickman completed the grand slam of ultra running, meaning she finished four of the oldest 100-mile races in a span of 10 weeks. She is one of only 59 women who have accomplished the feat since it was established in 1986. She also completed the Leadville Trail 100 a total of 14 times (within the time limit), the most by any woman at the event. Now, at almost 75 years old, Hickman still competes regularly as an enduring pioneer in the sport.
