This week, Corinne Malcolm sits down with Canadian runner Jenny Quilty to talk about curiosity and why she balances epic mountain events with flat fast racing. If you don't know Jenny yet, you should! She's won some of the most famously hard races on the circuit.

They talk about:

• Why she picks races by feel and what she wants to do — even if that means skipping UTMB this year
• How her relationship with running has changed over time
• Mixing up the courses, terrain, and training

And, of course, the topic on everyone's mind this week: Did Rachel Entrekin's win at Cocodona 250 change the game for the 200+ distance? Did her race give you JOMO or FOMO?

Do you know your sweat rate? Or how much sodium you should be replacing as the weather gets hotter? That's what today's episode is for!

This week, Corinne Malcolm and Keely Henninger dive into all things hydration as the season and the sun heats up. They break down:

• Osmolality and what it means for training and racing
• How to do some basic sweat testing at home
• And, of course, balancing hydration with carb intake and fueling!

As the miles and temps rise, managing sodium, water, and calories — without GI issues! — can seem like an unsolvable puzzle. Here are some practical tips for building a plan to hold up as you hit start lines this summer.

This week, Corinne sits down with Lizzy Fowler for a conversation about identity, resilience, and rebuilding after life splits into "before" and "after." They talk about Lizzy’s traumatic brain injury in college, the long process of learning to live in a body and brain that felt unfamiliar, and how ultrarunning became a way to test her edges, find flow, and begin trusting herself again.

• The two also dig into trauma and sexual assault
• Why she chose to share her story and work with Take Back the Night
• And how taking on the John Muir Trail became about far more than sport

It’s a conversation about disruption, self-discovery, and the versions of ourselves we become when everything changes.

This week, Corinne Malcolm and Hillary Allen are tackling the topic of belief and the role self-belief plays as a performance tool.

1. How belief shapes attention, effort, and perception
2. Why expectations can change the way training and racing feel
3. And how athletes can use practical mindset tools to build confidence in real time

They also dig into the science behind placebo effects, performance, and fatigue—plus share actionable ways to shift your focus, reframe hard moments, and lean into effort when things get tough.

Researcher and runner Katherine Boere joins Corinne to talk about the connection between physiological depletion and cognitive function in runners. We've all been there: Making wild choices late in races that we swear seemed to make sense at the time. Why do decisions seem to get harder after you've run farther?

The two of them dig into:

• the research around cognitive fatigue in marathons and ultramarathons
• what role low energy availability plays
• and what it means for how you train, fuel, and recover

Boere is a Ph.D. candidate in the neuroscience program at the University of Victoria and a senior performance researcher at the Nike Sport Research Lab. And much or her research is inspired by her own experience putting in the miles out on the trails.

In this episode of Trail Society, Corrine and Keely dig into the question a lot of female athletes ask this time of year, as training starts to ramp back up: Is this normal fatigue, or could it be anemia?

1. They break down the difference between training stress and iron deficiency
2. Why ferritin matters even when your labs look “normal”
3. And what athletes should pay attention to when their body starts feeling off

Plus: spring race season news, a major WNBA update, and a few standout stories from the Trail Society community.

Olympic medalist Shannon Rowbury and pelvic health physical therapist Jess Dorrington join Corinne to talk about their new book, Strong as a Mother, and the bigger conversation around pregnancy, postpartum, and athleticism. Together, they explore what it means to stay active during pregnancy, how runners can think about returning to sport postpartum, and why strength during motherhood may look different, but no less powerful.

They also dig into pelvic floor health for runners, common misconceptions around exercise during pregnancy, and why so much advice in this space can feel confusing or incomplete. Jess breaks down why pelvic health matters not just for pregnant and postpartum athletes, but for runners more broadly, while Shannon reflects on her path from Olympian to mom rediscovering joy in movement.

Along the way, they talk about how Strong as a Mother came together, why the title changed from Running for Two, and what they hope athletes, moms, and active women take from the book: your body is capable of more than you think, and there is no one right way to move through this season. Shannon also shares more about her long Olympic medal journey and anti-doping advocacy.

In this episode:

• Shannon Rowbury’s running career and Olympic medal journey
• Jess Dorrington’s path into pelvic health physical therapy
• Why pelvic floor health matters for runners
• Exercise during pregnancy and returning to sport postpartum
• Writing Strong as a Mother

Jane Maus is coming off a huge early-season win at Black Canyon 50K — but her story is about far more than a finish line.

From battling chronic pre-race nerves to chasing the Grand Teton FKT, making the Short Trail World Championships Team, and stepping into a new partnership with Arc’teryx, Jane’s last two years have been anything but linear.

In this episode, we talk about:

1. Why she struggles to even make it to start lines
2. The move from Salt Lake City to Boulder and entering the “Boulder Bubble”
3. Working with coach Rick Floyd and managing chronic injury
4. Racing Jazmine Lowther for the Grand Teton FKT
5. Finding flow on technical terrain
6. Why 50K racing currently suits her body better than 100-milers
7. Kicking off 2026 with a Black Canyon win

Jane’s story is about fitness built in the mountains, confidence built through racing, and learning to be competitive with your teammates.
