In Episode 113 we sit down with Dr. Margie Davenport, Professor of Kinesiology and Director of the Program for Pregnancy and Postpartum Health at the University of Alberta. Margie has spent more than two decades advancing the science of exercise during pregnancy and postpartum, collaborating with organizations including FIFA, Sport Canada, ACSM, and the Society of Obstetricians and Gynaecologists of Canada. She walks us through the transformative cardiovascular, metabolic, and biomechanical adaptations that make pregnancy "the ultimate stress test," while explaining how exercise supports both maternal and fetal health.

We also dig into her recent work on long-duration training during pregnancy, postpartum return-to-run recommendations, pelvic floor considerations, and the complex intersections of REDs, mental health, breastfeeding, and musculoskeletal injury risk. Margie's research dispels longstanding misconceptions and offers evidence-based guidance for athletes who want to stay active through every stage of pregnancy and return to sport with confidence. This is an essential conversation for anyone who cares about the science of women's health and performance.

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.

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.
