Episode 154: Building a Bigger Trail Running Community with Vivek Gowri
This week, Corrine Malcolm sits down with Vivek Gowri, owner of San Francisco Running Company, for a conversation about community, representation, and what it means to help more people feel like trail running is a place where they belong. Vivek shares how he found his own running community in the Bay Area, what SFRC meant to him long before he took over the business, and how he’s approached evolving such an iconic local institution without losing what made it special in the first place.They also dig into the barriers that can make trail running feel inaccessible, why simply inviting people in is different from creating a genuine sense of belonging, and how running stores, races, and community leaders can help grow the sport rather than fight over the same existing audience. Vivek also shares the thinking behind SFRC’s women’s trail half marathon and the Get Her Over the Bridge initiative, including training support, postpartum and pregnancy deferrals, childcare grants, and a substantial prize purse designed to support both first-time participants and elite women racing at the front.Follow Us:Courses and Coaching: https://livefeisty.com/courses/@feisty_media@trail.societySupport our Partners:Use the code FEISTY2026 for 20% off at https://www.tifosioptics.comProBio: Use code Trail20 for 20%-off orders (30%-off + free shipping w/ subscriptions) at https://www.probionutrition.com/rabbit: Visit https://www.runinrabbit.com/ use code: TRAILSOCIETY10 for 10% off.

Episode 153: What Happens to Your Body After an Ultramarathon?
This week, Corrine Malcolm and Keely Henninger nerd out on what actually happens inside your body during — and after — an ultramarathon. Using recent research alongside what we already know about endurance physiology, they work system by system through the muscle damage, inflammation, kidney stress, cardiovascular changes, neurological fatigue, immune response, metabolic shifts, and GI issues that can come with pushing your body for hours on end.They also dig into the difference between normal post-race weirdness and something worth paying closer attention to, why recovery can take much longer than simply waiting for sore legs to disappear, and what we still don’t know about the long-term effects of repeatedly racing and training at ultra-endurance volumes. Along the way, they talk about CK and rhabdo, acute kidney injury, post-race hypotension, heart remodeling, cognitive fatigue, RED-S, GI distress, and why fueling, hydration, sleep, and adequate recovery matter so much.It’s a science-heavy conversation about what your body is actually managing when you ask it to run really, really far — and why understanding that process can help you recover better and keep doing this sport for the long haul.That last paragraph is the framing I like most for this one: not “ultrarunning is secretly killing you,” but “this is an enormous physiological event, so maybe give your body some respect afterward.”

Episode 152: Jessie Diggins on Becoming a Beginner Again
This week, Corrine Malcolm sits down with Jessie Diggins, Olympic champion, multiple-time World Cup overall champion, and one of the most accomplished American cross-country skiers ever, for a conversation about what happens when sport stops being your job. Now retired from professional skiing, Jessie is stepping into a very different chapter — one that includes trail running, public speaking, advocacy, and learning what it feels like to be a beginner again.They talk about identity after elite sport, what training means when there isn’t a podium waiting at the end, and how Jessie is deciding which parts of her competitive life she wants to carry forward. They also dig into her first 100-miler at Minnesota’s Superior 100, the team she brought along for the experience, what surprised her about the distance, and whether she’s caught the ultra bug.It’s a thoughtful conversation about reinvention, curiosity, and what it looks like to keep loving sport when the outcome no longer has to mean anything.Follow Us:Courses and Coaching: https://livefeisty.com/courses/@feisty_media@trail.societySupport our Partners:Use the code FEISTY2026 for 20% off at https://www.tifosioptics.comProBio: Use code Trail20 for 20%-off orders (30%-off + free shipping w/ subscriptions) at https://www.probionutrition.com/rabbit: Visit https://www.runinrabbit.com/ use code: SEPTEMBERTRAIL10 for 10% off.

Trail Society Rewind: Strong As a Mother with Jess Dorrington and Shannon Rowbury
This episode originally aired March 31st, 2026Olympic medalist Shannon Rowbury and pelvic health physical therapist Jess Dorrington join Corrine 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.Follow Us:Courses and Coaching: https://livefeisty.com/courses/@feisty_media@trail.societySupport our Partners:Use the code FEISTY2026 for 20% off at https://www.tifosioptics.comProBio: Use code Trail20 for 20%-off orders (30%-off + free shipping w/ subscriptions) at https://www.probionutrition.com/rabbit: Visit https://www.runinrabbit.com/ use code: SEPTEMBERTRAIL10 for 10% off.

Episode 151: Building Your Team and Finding the Right Coach
This week, Corrine Malcolm and Hillary Allen dig into one of the most important — and sometimes overlooked — parts of an athlete’s support system: finding the right coach. They talk about what actually makes a good coach-athlete fit, from communication and collaboration to goal alignment, professionalism, and whether a coach is truly invested in you as a person rather than just your performance.They also explore the red flags that can emerge once a coaching relationship is underway, why athletes should pay attention to how a coach responds when things get hard, and what it looks like when a relationship simply reaches its natural end. Plus, they walk through what to do if a coach exits at a difficult moment, how to rebuild trust in a new coach, and why self-advocacy and a broader support team can make all the difference.It’s a practical conversation about building the right team around you, asking better questions early, and remembering that you’re allowed to want a coaching relationship that actually fits.Follow Us:Courses and Coaching: https://livefeisty.com/courses/@feisty_media@trail.societySupport our Partners:Use the code FEISTY2026 for 20% off at https://www.tifosioptics.comProBio: Use code Trail20 for 20%-off orders (30%-off + free shipping w/ subscriptions) at https://www.probionutrition.com/rabbit: Visit https://www.runinrabbit.com/ use code: SEPTEMBERTRAIL10 for 10% off.

Chelsea shares what she learned about the support athletes actually need, why maternity policies are only the beginning, and how projects like Unlocking Yes are helping her turn her own experience into something bigger.It’s a thoughtful conversation about motherhood, ambition, identity, and what sport could look like if women didn’t have to be extraordinary just to have the freedom to choose more than one thing.Follow Us:FeistyFest Details and Registration: https://livefeisty.com/events/feisty-fest/Courses and Coaching: https://livefeisty.com/courses/@feisty_media@trail.societySupport our Partners:Use the code FEISTY2026 for 20% off at https://www.tifosioptics.comProBio: Use code Trail20 for 20%-off orders (30%-off + free shipping w/ subscriptions) at https://www.probionutrition.com/rabbit: Visit https://www.runinrabbit.com/ use code: SEPTEMBERTRAIL10 for 10% off.
