In episode 95 of Trail Society, hosts Corrine Malcolm, Keely Henninger, and Hillary Allen sit down with two standout researchers from Stanford University—Dr. Morgan Smith and Naiomi Hunter—for an insightful conversation about the intersection of women's health, athletic performance, and wearable technology. Dr. Smith, a sport scientist, coach, and postdoctoral fellow with the Wu Tsai Human Performance Alliance at Stanford, is passionate about how physiology and metabolism influence performance, especially for women in sport. Her research is grounded in the real world, as she also coaches high school athletes, lifts weights, and enjoys time outdoors with her dog, Reggie. Naiomi Hunter, a PhD candidate in Stanford's School of Medicine, focuses on the menstrual cycle and its impact on female athlete performance through wearable tech and biometric data. With a strong commitment to reproductive justice and healthcare equity, Naiomi’s work seeks to create more inclusive and personalized approaches to reproductive care for marginalized communities. In this episode, they explore the potential of wearables in tracking menstrual cycle data, the challenges in the current research, and why individualized training plans are key to optimizing performance. They also discuss the importance of mentorship for women of color in science, their passion for combining sport and research, and the exciting future of wearable technology in improving athletic health.

In this episode of Trail Society, Corrine Malcolm, Hillary Allen, and Keely Henninger dive into the topic of goal setting for athletes, focusing on the importance of aligning both goals and values to enhance performance and motivation. They discuss the common tension between being process-oriented versus outcome-driven, and how athletes often get caught up in the race calendar without understanding their deeper "why" or core values. The conversation emphasizes how discovering your personal "North Star"—the driving force behind your actions—can help avoid burnout and misalignment, leading to more fulfilling and sustainable progress.
The trio also reflects on the challenges of staying consistent with basic principles, even when more glamorous solutions seem tempting. Drawing from insights in Brad Stulberg's work, they stress the value of focusing on the process itself rather than obsessing over the outcome. The episode encourages athletes to embrace their core values—whether it’s perseverance, integrity, or self-improvement—and use them as guiding principles throughout their training and race journeys. Ultimately, they highlight that true success lies in the commitment to consistent, incremental effort rather than expecting a singular goal to change one's life.

In Episode 90 of Trail Society, we sit down with Leela Srinivasan, the CEO of Parity Now, a pioneering platform that aims to close the gender income and opportunity gap in professional sports. Parity, founded in 2020, works with over 1,000 women athletes across 80+ sports, from archery to weightlifting, empowering athletes through impactful brand partnerships. Leela, a runner, mother, and passionate advocate for women's sports, brings her unique perspective to the conversation, exploring how her platform is reshaping the future of women's athletics. Her leadership at Parity is focused on tackling the financial inequities faced by female athletes, with an emphasis on securing meaningful sponsorships and creating long-term opportunities for women in sports.
A key highlight of this episode is the release of Parity's groundbreaking research, "Beyond the Game: Exposing The Economic Realities of Professional Women Athletes". The study sheds light on the harsh financial realities faced by many female athletes, with findings such as 50% reporting a negative or zero net income, and 74% working another job to make ends meet. Leela discusses the contrast between the booming investment in women’s sports leagues, like the NWSL and WNBA, and the ongoing struggles for athletes themselves. Despite these challenges, the research also highlights the potential for growth in women’s sports, with consumers increasingly backing brands that support female athletes. Leela’s insights into the disparity between league success and individual athlete earnings offer a sobering look at the financial landscape, while also providing a call to action for brands and fans to invest in women’s sports to create lasting change.

In Episode 87 of Trail Society, the gang is back together for a deep dive into the intersection of ultra running and cognitive performance. Corrine, Hillary, and Keely unpack recent research from the world of Backyard Ultras, where a group of Belgian scientists explored the effects of extreme endurance on the brain. The study, conducted during an April 2023 event, found that while sleep deprivation and fatigue did slow reaction times, for the athletes that lasted the longest, physical performance remained stable. This episode explores how mental fortitude — the ability to push through the struggle to continue — might be just as critical as physical endurance in ultra running and beyond. Can the mental endurance required for these extreme races teach us how to better manage our effort and focus in other areas of life?
We also shift gears into the world of self-esteem and positive self-talk, exploring how these mental strategies can enhance athletic performance and improve overall well-being. With insights from psychological research, Hillary guides us through the latest findings on how positive self-talk can boost motivation and confidence in athletes. Whether you're running a race or tackling a big challenge in life, the ability to stay focused, motivated, and positive can make all the difference. Tune in for a conversation on how ultra runners and everyday athletes alike can leverage their mental game to go further, faster, and stronger.
