Episode 108 brings all four hosts back together for a rare catch-up episode, and the conversation covers everything from ambitious running goals to the realities of trying to fit training into already full lives.

After a few chaotic weeks away from the mic, Katie is back and catching up with Leah on everything that’s unfolded lately, from her son's type 1 diabetes diagnosis to the emotional whiplash of balancing family crisis with training, racing, and everyday life. It’s an honest conversation about what happens when running suddenly takes a backseat, and how both of them are navigating UTMB build-up while life keeps throwing curveballs.

They also get into local race wins, steep Salt Lake climbs, late-night mountain runs, Western States pacing plans, Broken Arrow prep, and the momentum women’s trail running is carrying right now after huge performances from Rachel Entrekin, Tove Alexandersson, and more. Through all of it, this episode comes back to the same idea: running can be part of your life without being your entire identity.

After a chaotic lead-up that included travel stress, illness, childcare logistics, and a race that almost didn’t happen, Rachel and Tyler Green made it to Madeira… and ended up delivering two standout performances on one of the most technical courses in the sport.

In this episode, Hilary sits down with both Rachel and Tyler to unpack what it actually looked like behind the scenes. This isn’t just a race recap. It’s a conversation about showing up when nothing feels perfect, trusting your process when confidence is low, and navigating high-level racing while balancing careers, parenting, and real life.

Tyler shares what it meant to finally feel like himself again at the front of an international field, and how he managed the inevitable highs and lows of a long race day. Rachel opens up about racing postpartum, letting go of expectations, and finding joy and perspective in a season that looks very different than before.

There’s also a deeper look at partnership, support systems, and what it really takes to make racing at this level possible. From family logistics to mid-race problem solving, this episode pulls back the curtain on what goes into these performances beyond the results.

It’s a reminder that very few races start from a place of perfect preparation, and that sometimes the most meaningful outcomes come from the messiest lead-ups.

This week’s catch-up episode leans into where the sport is right now and how quickly everything seems to be evolving.

With Rachel off racing in Madeira, Katie, Leah, and Hilary sit down to unpack a stretch of racing that felt bigger than usual. From the ACG takeover at Gorge to the growing presence of brands, media, and storytelling in trail, there’s a clear shift happening in how races are experienced, marketed, and consumed. It’s not just about who wins anymore. It’s about how the sport shows up.

The conversation naturally moves into what that means for athletes. The pressure that comes with bigger platforms, the reality of bad race days, and the challenge of staying grounded when expectations keep rising. There’s an honest look at how pros navigate performance swings, sponsorship dynamics, and the mental side of showing up again after things don’t go to plan.

They also touch on the increasing overlap between road and trail, with more athletes moving between disciplines and finding breakthroughs by doing things differently. It’s less about choosing one lane and more about building a broader version of what it means to be an endurance athlete.

As always, it circles back to real life. Training interruptions, family logistics, travel fatigue, and finding small ways to keep showing up anyway. It’s a reminder that even at the highest level, there’s no perfect formula. Just people figuring it out as they go.

Robyn Lesh is one of the most interesting athletes in trail running right now because of how quickly she’s figuring things out and the results that are coming with it.

A former competitive sailor and MIT-trained engineer, Robyn came into trail running without a traditional background in the sport. In just a few years, she’s gone from learning how to pace her first ultras to racing at the front of some of the most competitive fields in the world.

This conversation digs into that progression. What it actually feels like to step up in distance. How you learn to push deeper when you don’t know where the limit is. And what happens when you stop racing cautiously and start racing to compete.

There’s also a lot here beyond results. Robyn shares how her background in sailing shaped her mindset, why she initially stepped away from being an athlete, and what brought her back. The conversation touches on sponsorship, learning in real time, and the moments in races where things start to go sideways — and you have to decide whether to back off or keep going.

It’s an honest look at what it means to still be learning while showing up at a high level, and why that might actually be the advantage.
