Trail Society

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.     Thank you to our sponsor, rabbit, for making this happen!

In Episode 112 of Trail Society, Corrine, Keely, and Hillary head to the desert for the Javelina Jundred. Keely was on the ground with the rabbit x Trail Society scholarship athletes, Clarivel Vega and Daisy, crewing, pacing, and celebrating their powerful performances. From first trail race jitters and high and low moments, to late-night grit, the weekend was a reminder that showing up for one another can make all the difference. The crew dives into what it means to create access, not just by giving out scholarships, but by building community and support systems that help women get to the start line and stay in the sport. They also discuss cut-off times in ultra races and how expanding the times may impact finish rates and access to women.  They also recap some of the record-breaking performances from Javelina's golden ticket chase and reflect on how mentorship and representation can spark the next generation of trail runners.   Big shout out to our sponsor, rabbit, for helping us with this scholarship.

In this episode of Trail Society, Corrine, Keely, and Hillary sit down with researcher Jill Colangelo to unpack their newly published review, "Exploring the Presentation of REDs in Ultra Endurance Sport." This conversation dives deep into the intersection of low energy availability (LEA), disordered eating (DE), and exercise dependence (EXD), issues that are all too common yet rarely discussed openly in the ultra-endurance community. Many athletes are unknowingly underfueling, especially for efforts lasting over two and a half hours, and whether this is intentional or unintentional, the consequences can be profound. The discussion explores how extreme training volumes, psychological pressures, and cultural norms around toughness and body image make ultra athletes uniquely vulnerable to both the physiological and psychological components of Relative Energy Deficiency in Sport (REDs). Together, Jill and Keely break down what current research tells us, and what's still missing, about fueling, recovery, and mental health in endurance athletes. They also tackle one of the hardest questions for athletes and coaches alike: how do we tell the difference between being disciplined and being disordered? This episode challenges assumptions, questions long-held beliefs about "grit" in sport, and offers a more compassionate lens on what it means to truly care for the athlete's body and mind.

In this episode of Trail Society, Corrine, Keely, and Hillary break down an action-packed World Mountain and Trail Running Championships, where Team USA came away with hardware and Hillary surprised us all with a double, competing in both the vertical and the long trail events. Hilly shares what it was like to rock the Team USA kit, how she pivoted from preparing for a one-hour climb to suddenly taking on an 80km ultra, and what she learned from the experience. The crew also highlights the story of Clarivel Vega, this year's 30km Javelina Trail Society Scholarship recipient. A first-generation Latina and lifelong runner, Clarivel has found strength, resilience, and belonging in the running community after growing up without family support for her sport and managing a chronic illness. From her roots in Santa Ana with Keep Runnin Santa Ana to her new adventure on the trails, her story is a powerful reminder of why representation matters and why we're committed to getting more underrepresented runners to the start line.   HUGE thanks to our sponsor rabbit for helping us with this scholarship.

Episode 109 of Trail Society features an inspiring conversation with Daisy Martinez, the rabbit x Trail Society 100K scholarship winner whose story embodies resilience and representation. A Mexican American ultrarunner from Los Angeles, Daisy started trail running in 2016 and has since transformed personal challenges into fuel for her running journey. As a teen parent and now single mother, she credits the endurance and grit she built while raising her son with helping her push through the mental and physical demands of ultrarunning. Diagnosed with Multiple Sclerosis in 2023, Daisy has been learning how to continue pursuing the sport she loves while managing the realities of an autoimmune disease. Beyond her personal racing goals, Daisy is driven by a deep commitment to community. She co-founded Chingonas on the Run to empower women, especially women of color, to take up space in trail running and the outdoors. From racing her first ultramarathons, to training for Javelina 100K, Daisy embraces each challenge as a way to learn, grow, and inspire others. Through her scholarship, she hopes to show what's possible when passion meets support, and to blaze a trail for more underrepresented runners at start lines everywhere.  We are so excited to see what she can do at Javalina!

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.   SPONSORSHIP:  We are so excited to be partnering with rabbit as our primary apparel sponsor this year!

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.
