  • Episode 116: Reflecting on 2025, ReFUEL study updates, and Looking Ahead
    Dec 30 2025

    Episode 116 is a year end reflection with Corrine Malcolm, Keely Henninger, and Hillary Allen, released just ahead of the New Year. The conversation opens with lighthearted check ins on holiday routines, winter training, and how each host plans to ring in 2026. From there, the episode moves into results, news, and science, including a detailed discussion of new findings from the ReFUEL study examining menstrual recovery, estrogen exposure, and ovulation in endurance athletes with functional hypothalamic amenorrhea and oligomenorrhea. The hosts unpack what it actually means for cycles to return, why multiple consecutive cycles matter, and how this research informs coaching, athlete health, and family planning conversations.

    The second half of the episode is a wide ranging reflection on the year that was. Corrine, Keely, and Hillary look back on major themes from Trail Society in 2025, including athlete contracts, travel and racing highlights, fertility, resilience, fatigue, recovery, and women's sports milestones. They reflect on favorite conversations and guests, moments that surprised them, trends they are ready to leave behind, and ideas they hope shape the future of the sport. The episode closes with personal roses and thorns from the year, Society Slam listener questions, and an exciting announcement about what's coming next: a short break, a new weekly format in 2026, and even more long run listening ahead.

  • Episode 115. The Science of Resilience: Why Environment Matters More Than Toughness
    Dec 16 2025

    Episode 115 is a winter roundtable with Corrine Malcolm, Keely Henninger, and Hillary Allen that explores how resilience in endurance sport is built not in isolation, but through people, culture, and environment. We open by checking in on winter training realities across snow, mud, rain, and darkness, and how community helps athletes keep showing up during the hardest part of the year. The episode also covers standout performances from CIM, including a historic day for women chasing the Olympic Trials standard, updates in women's sport science and leadership, and notable moments across trail, road, and skimo.

    At the heart of the episode is a deep dive into new research by Chen et al. (2024), which challenges the idea that resilience is an innate trait. Instead, the study shows how grateful team climates foster individual gratitude and long-term psychological resilience. Hillary breaks down the science behind coaching environment, gratitude, and burnout prevention, connecting it to real-world trail running experiences. Together, the hosts reflect on where resilience actually comes from, how grit is often confused with adaptation, and what coaches, teammates, and communities can do to create environments where athletes grow braver rather than smaller. The episode closes with Society Slam listener questions and examples of organizations doing it right when it comes to supporting athletes through pregnancy, setbacks, and long-term participation in sport.

  • Episode 114. UTCT Deep Dive: Training, Travel Chaos, and Race Week Curveballs
    Dec 2 2025

    Episode 114 takes us to Cape Town as Corrine gives a full UTCT race recap, reflecting on why she returned to the Deep South, the big-volume training block leading in, and the challenges of racing after travel sickness and time zone chaos. We talk pacing through the first 50 kilometers, fueling decisions, and what makes a night start feel uniquely disorienting. The conversation touches on heat training, mental reframing, and the honest emotional landscape of managing expectations when things out of your control land in your lap during race week.

    We also round up an exceptionally fast weekend of racing across the globe including standout results from the JFK 50 Mile, the competitive UTCT podium battles, and record-breaking runs at the Quad Dipsea. Wrapping with recovery plans, what is coming next, and a Society Slam covering ultralight waterproof jacket recommendations and the wide range of pregnancy running experiences, this episode brings together community, science, and the real-life messiness of training and performing.
