Episode 107 of Trail Society kicks off with life updates from Keely and Hillary, before diving into listener-submitted news and research. They discuss a BBC story where undercover officers highlighted the prevalence of street harassment, with 94% of local women reporting experiences of catcalling. This transitions into a conversation around exercise during pregnancy, sparked by a listener question about heart rate guidelines. The hosts review current research showing that, for athletes already active, higher intensity exercise can be safe and even beneficial during pregnancy, lowering risks like gestational diabetes and improving newborn Apgar scores. They emphasize that heart rate is an imprecise measure, and individualized approaches are important.

The main feature of the episode is an interview with Anne Flower, an ER physician and elite trail runner who recently won and set a new course record at the Leadville 100, her debut 100-mile race. Anne shares how she balances training at a world-class level with her demanding medical career, and how lessons from the ER and ultrarunning inform each other. She reflects on her road-to-trail transition, the highs and lows of Leadville, and her mindset of tackling hard things as practice for resilience. Anne also discusses her role as Chief Medical Officer for Mountains to Mountains, her future racing goals, and offers advice for women entering the sport. The episode closes with listener shoutouts, stories of recovery after long races, training adaptations for different terrains, and heartfelt community support, reinforcing the podcast’s commitment to uplifting women in endurance sports.

Episode 106 of Trail Society opens with the hosts catching up after a busy stretch of travel, training, and transitions, sharing experiences from Alaska fast-packing, Wyoming family visits, and runs on hometown singletrack. The conversation then shifts to the Tour de France Femmes avec Zwift, highlighting Pauline Ferrand-Prévot’s long-awaited victory and the breadth of her multi-discipline cycling career. While her win came after a calculated, team-guided performance plan that included a 4 kg weight reduction, the hosts discuss how such strategies can raise health concerns, especially in a sport with a history of under-fueling and the belief that “lighter is always better.” They explore the risk that focusing on weight, both in training and in media coverage, can perpetuate unhealthy body standards, particularly for young women who may try to emulate elite athletes without the same medical oversight or resources. The discussion considers how to balance performance optimization with athlete well-being and how coverage could better reflect the complexity of such decisions.

The episode also examines new research on self-efficacy and fatigue, showing how endurance limits are influenced by the brain’s ability to predict and sustain effort. Studies on subliminal cues suggest that positive mental inputs can extend performance, reframing fatigue as partly a perception-driven process. Listener “Society Slams” bring forward concerns about limited access to women’s race coverage, suggestions for scenic, low-altitude trail races ideal for groups, and lighthearted reflections on dream race snacks that don’t sit well mid-run. Through these segments, the episode blends athlete health, sports science, and community conversation.

In this electric post-race episode of Trail Society, Corrine Malcolm sits down with co-host and freshly minted Western States Top Ten finisher Keely Henninger to relive the highs, lows, and hard-earned triumphs of this year’s race. Keely reflects on her fourth go at WSER, this time arriving with a deeply personal approach, hard-won confidence, and zero obligations to perform for a brand—just herself. From a ferocious women’s field to a historic showing by international athletes, Corrine and Keely break down everything that made this year's race unforgettable, including the dramatic chase to crack the top ten.

They dive into Keely’s evolving mindset, her take on the lead women going out hot, how it felt to go “on the hunt” post-Foresthill, and how finally nailing her fueling strategy played a pivotal role. The episode touches on gear freedom, team dynamics, and what it's like to finish with joy instead of just survival. With questions from listeners and big-picture reflections, this conversation is a celebration of grit, growth, and the power of running on your own terms.

In this episode, ultrarunner, OB/GYN board certified physician, and mom of two Lauren Puretz, DO, returns to the podcast to dive deep into women’s health with a focus on athletes navigating fertility, pregnancy, and postpartum. Lauren discusses complex reproductive health conditions like PCOS and endometriosis, especially how they present uniquely in athletic populations. She emphasizes the importance of proper diagnosis, individualization of treatment, and how these conditions can affect energy levels and performance. She offers practical advice for athletes with insulin resistance and stresses the importance of advocacy when pain is being overlooked in clinical settings.

The conversation then shifts into training during pregnancy and the often-overlooked postpartum period, where Lauren draws from both medical expertise and personal experience. She breaks down trimester-specific considerations for athletes, safe return-to-sport strategies, and how tools like belly bands can help. The hosts and Lauren tackle common but under-discussed challenges such as postpartum hormone shifts, fatigue, and breastfeeding demands on athletes. The episode closes with a powerful question on what changes Lauren would make in the medical system to better support female athletes across their reproductive lifespan, highlighting the need for more inclusive, evidence-based care and research for all stages—from puberty to perimenopause.

In Episode 101 of Trail Society, OB/GYN, ultrarunner, and mom of two Dr. Lauren Puretz joins Corrine, Keely, and Hillary for a candid and insightful conversation about puberty, birth control, and fertility in female athletes. Drawing from both her medical practice and personal experience as an elite endurance athlete, Dr. Puretz breaks down complex topics like energy availability, menstrual health, and hormonal birth control, offering practical advice for athletes navigating these issues. The discussion highlights how puberty and menstruation are affected by training load, the importance of not masking menstrual irregularities with birth control, and how coaches and caregivers can support young athletes during this pivotal time.

The conversation also explores fertility concerns in current and retired athletes, including whether period loss during early athletic years may impact long-term reproductive health. Dr. Puretz discusses proactive steps athletes can take, such as hormone testing and fertility planning, and the growing trend of egg freezing among those delaying parenthood. Her honest and empowering perspective sheds light on the lifelong health journey female athletes face, from adolescence to adulthood, and sets the stage for a deeper dive into pregnancy and postpartum care in the next episode.

In this milestone 99th episode of Trail Society, we go all-in on Keely Henninger’s third-place finish at the Canyons 100K, earning her a coveted Golden Ticket to Western States. Keely walks us through her decision to return to Western States, how she managed training on reduced mileage while in med school, and the strategies she used to stay consistent under immense pressure. We dig into the physiology, planning, and mindset shifts that made this comeback possible—including how stepping away from sponsorship has reshaped her relationship with competition.

Listeners will get detailed answers to real questions from the trail community: what does tapering for a 100K really look like? How do you fuel during a freezing wet race? Can long hours on your feet at work substitute for running volume? Keely shares what went right, what she learned from what didn’t, and how she’s preparing to level up for Western States. Plus, we cover gear (including the story behind those glasses), race-week nutrition tweaks, and how elite women are balancing ambition with authenticity in sport. If you’re navigating time constraints, training stress, or racing with less-than-ideal prep—this conversation offers both practical takeaways and serious inspiration.

In Episode 98 of Trail Society, Corrine, Keely, and Hillary recap a big weekend at the Gorge Waterfalls races, touching on standout performances, course records, and the ongoing shift toward spring in the Pacific Northwest.

It’s a practical, no-nonsense conversation for anyone looking to better fuel their training and everyday life.
