Mary Cain was born to run, a natural talent whose journey into the world of athletics began at a tender age. At just 12 years old, she joined her school’s varsity track team in Bronxville, New York, quickly outpacing even the seniors. With her astonishing speed, she shattered records and clinched championships, setting the stage for a promising future in competitive sports.
By 2013, Cain’s potential caught the eye of Alberto Salazar, the renowned coach behind Nike’s Oregon Project. This elite training program, based at Nike’s Beaverton, Oregon campus, boasted state-of-the-art facilities and a reputation for nurturing world-class athletes. Cain joined the program at 16, becoming the youngest athlete to make the U.S. World Championship team, and the promise of Olympic glory seemed within her grasp.
However, the dream soon turned into a nightmare. As Kara Goucher, another Oregon Project athlete, recounted in her memoir, the resources available to Cain were immense—everything from top-notch equipment to medical care. Yet, the environment was not as supportive as it appeared. Cain later revealed that she was subjected to intense pressures regarding her weight and performance, leading her to train through serious injuries rather than seek help. The pressure culminated in her failure to qualify for the 2016 Olympics, a devastating blow that prompted her to leave the Nike team and retreat from the spotlight.
In a courageous move, Cain resurfaced in 2019, publicly denouncing the toxic culture of the Oregon Project. She accused Salazar and other coaches of fostering an environment that prioritized weight loss over the well-being of athletes. By 2021, she had filed a $20 million lawsuit against Salazar and Nike, claiming emotional and physical abuse, as well as a lack of protection from the organization.
Now at 29, Cain is pursuing a new path as a medical student at Stanford University, but her journey has been anything but linear. After her departure from the Nike Project, she faced multiple health challenges, including being diagnosed with Relative Energy Deficiency in Sport (REDs) and undergoing surgery for functional popliteal artery entrapment syndrome. The physical toll of her experiences has been profound, but it also inspired her to turn her pain into purpose.
In her forthcoming memoir, “This Is Not About Running,” scheduled for release on April 28, Cain addresses the broader implications of her story. She argues that the sports culture often normalizes the abuse of young athletes, highlighting a systemic issue that extends beyond her personal experiences. As she articulates, “sports normalizes cruelty,” noting that the problem is pervasive, affecting athletes across various disciplines and industries.
Cain’s reflections also dive into the troubling dynamics she faced as a young athlete. Her high school coach’s obsession with her weight led to severe consequences, including self-harm and suicidal thoughts. She recounted incidents of bullying from teammates and their parents, which created an environment where she felt unsafe and unsupported. Despite contemplating a transfer to escape the hostility, she held on, believing in the possibility of change.
Ultimately, Cain’s journey is not just about her individual struggles; it serves as a rallying cry for reform in youth sports. She emphasizes the need for accountability among coaches, the media, and organizations that profit from young athletes. “You don’t have to be a runner to find value in this book,” she asserts, inviting a wider audience to recognize the patterns of abuse that can emerge in any competitive environment.
Today, Cain has founded Atalanta NYC, a nonprofit that empowers female professional runners to mentor girls in underserved communities. She has also joined the board of Athlete Survivors’ Assist, an organization committed to combating abuse in sports. Her return to running, marked by a newfound resilience and a commitment to her health, reflects a powerful personal transformation.
“This past year has been this really incredible journey,” she shares, explaining her steady return to running. “I’m feeling so good and so resilient.” Cain’s story is one of reclamation, not just of her athletic career but of her identity and purpose. Through her advocacy and education, she aims to ensure that the next generation of athletes can pursue their dreams in a safer, healthier environment.
