Steve House sits down with elite mountain athlete Kílian Jornet, calling in from his home in Norway, for a wide-ranging conversation about what draws people to high-risk mountain pursuits. They explore mountains not as a destination but as a sense of home and identity, the fine line between earned confidence and dangerous complacency, and how fear and euphoria can each distort decision-making in exposed terrain. Jornet reflects on his upbringing; being "born into the mountains," his mother's nighttime forest walks, a family trek across the Pyrenees; and how he's now passing that connection to nature on to his own children with his wife, Emily. The two discuss the blurred lines between mountaineering, alpinism, and running as labels; the philosophy behind going fast and light versus slow and immersive; and the particular psychology of "accepting" mortal risk versus fighting to survive an emergency. The conversation turns deeply personal as Kílian opens up about the loss of his friend and climbing partner Stefane Brosse and how grief and loss reshapes friendships, risk tolerance, and one's relationship with death across cultures. They close on parenthood, legacy, and the freeing realization that, ultimately, no one will be remembered. What matters is being present, honest, and good to the people around you now.

Who Says Yes?

Steve House sits down with client René Morkos to unpack his Everest summit and the profound, almost spiritual experience he had on the summit ridge. René describes the physical transformation five and a half years of structured training brought him — from a non-athlete to one of the fittest climbers on the mountain — and how that fitness "buffer" let him fully experience rather than merely survive the climb. The conversation moves through his systems-thinking background (a Stanford PhD in AI applied to construction), his formative years surviving war in Beirut and rebuilding infrastructure in Afghanistan, his personal framework for risk-taking, and the mysterious, overwhelming sensation he felt above 8,600 meters that he still can't fully explain. They close by comparing mountaineering to other transcendent experiences (Burning Man, live music) and reflecting on why the training itself — not just the summit — is the lasting reward.

Endurance and Enlightenment on Everest

Steve House sits down with Hunter Allen — cycling coach, co-creator of TrainingPeaks, and co-author of Training and Racing with a Power Meter — for a wide-ranging conversation on training technology through the lens of the hype-adoption-disillusionment cycle. They trace the power meter's unusual "trickle-up" adoption (from data-driven amateurs to pros around 2008-2009) before working through today's landscape: HRV as a life-stress signal, the limits of wrist-based sleep tracking, the untapped promise of respiration and minute ventilation monitoring for mountain athletes, pulse oximetry's highly individual response to altitude exposure, heat/core-temperature training for hot events, skepticism around substrate utilization metrics, and the current bottlenecks holding back continuous lactate monitoring. The back half is a deep dive into continuous glucose monitors (CGMs), where Allen unpacks why endurance athletes run naturally higher glucose than the general population, why CGMs are both a performance and behavior-change tool, practical strategies like "food stacking" at meals, and why he recommends six months of wear time before drawing conclusions — closing with his take on where CGM technology is headed over the next decade.

The Evolution of Training Technology with Hunter Allen

Max King is the only American ever to win both the World Mountain Running Championship and the World 100K Championship. He joins Steve House for a wide-ranging conversation about identity, competition, and longevity in endurance sport. Max traces his path from a chemical engineering degree and Cornell track team to Olympic Trials appearances in both the steeplechase and marathon, his accidental first ultra the week after a disappointing Trials prelim, and his eventual move into trail and mountain ultrarunning, including a recent attempt at the Barkley Marathons. The two dig into the tension between elite competitiveness and the collaborative, adventure-driven ethos of trail culture, how aging athletes renegotiate identity as performance declines, and why Max is drawn to races defined by history and mythology (Barkley, Dipsea, Mount Marathon) rather than media hype. The conversation closes on Max's diversified career (coaching, race directing, youth camps, a new sponsorship with the Chinese brand Kailas) and his hope to be remembered for what he gave back to the sport, especially through youth development.

Voice of the Mountains: Legacy is Not the Measure with Max King

Steve House talks with legendary coach and author Joe Friel, now 82, about the newly released second edition of Fast After 50. Friel reflects on how a serious 2014 cycling crash reshaped his own training, and explains why the book's focus shifted from encouraging older athletes to add intensity (2012) to now urging them to build a much larger aerobic base, since he's observed most masters athletes over-doing high intensity and under-doing low intensity work. The conversation covers his "5+2" and "9-day" training patterns, how strength training is periodized across a season, the concept of durability (maintaining output late in long events) and how it's trained through fatigue-then-specificity workouts, muscular/strength endurance versus durability, adapting training around perimenopause, and the two key metrics Friel prioritizes with athletes: efficiency factor (EF) in base training and heart-rate/power decoupling in build periods. The episode closes on themes of patience, lifestyle identity, coaching athletes toward self-sufficiency, and Friel's core message: build the aerobic base first.

Training Considerations for Master Athletes with Joe Friel

In this Everest 2026 season recap, Steve House talks with Alan Arnette (Summit Coach) and Uphill Athlete coach Martin Zohr about a record-breaking year on the mountain: roughly 1,008 South Col summits (up from 891 in 2019), nearly 500 Nepal permits issued, nine straight days of delays from a massive leaning serac in the Khumbu Icefall, and a brief government ban on drone use that was reversed within days. They cover five climbing deaths (well below historical averages), the shift toward "flash" expeditions using higher-flow supplemental oxygen and pre-acclimatization on trekking peaks instead of traditional rotations, the stalled 7,000-meter prerequisite bill in Nepal's parliament, drones and helicopters replacing some Sherpa load-carrying, the unclear status of xenon use by climbers, Bartek Ziemkiewicz's no-oxygen ski descents of both Everest and Lhotse, and Nepal's roughly $8.5 million in permit revenue that largely bypasses local communities. The conversation closes with training advice — emphasizing a year or more of structured aerobic-first preparation, VAM tracking, and a mountaineering apprenticeship through progressively higher peaks — plus predictions for the 2027 season, including possible Tibet-side reopening.

2026 Everest Trends with Steve House, Alan Arnette, and Martin Zohr

Voice of the Mountains revisits one of its most memorable conversations (originally recorded in 2024, with a new intro from Steve House): Lydia Bradey, the New Zealand alpinist who in 1988 became the first woman to climb Mount Everest without supplemental oxygen and who would go on to guide six successful Everest summits, more than any other woman in history.  We're re-releasing this episode because the conversation was simply too good not to share again. Their discussion centers on a single, deceptively simple distinction: the difference between doing what people say you cannot do and doing what people say you should not do. Bradey traces her path from a self-described "wild child" raised by a single mother in New Zealand, through formative big-wall climbs in Yosemite and a near-fatal, avalanche-riddled epic in the Indian Himalaya, to the slopes of Everest itself, where she describes climbing "super altitude" not with dread but with pure curiosity. She and House dig into the bitter aftermath of her ascent — when senior male climbers on her own expedition publicly called her a liar, and half her teammates died descending the mountain — and how she navigated the threat of a ten-year climbing ban while quietly building a new life and career. Throughout, Bradey returns to themes of curiosity over fear, rejecting blame culture in favor of personal agency, and the idea that mastery of small, unglamorous tasks — sharp crampons, melted snow, a well-organized tent — is what earns a climber the right to take real risks. Asked how she wants to be remembered, her answer is unexpectedly modest: not for the summits, but simply as good company.

Steve House and Will Zittlau pull back the curtain on Continuous Aerobic Threshold, a new feature inside Uphill Athlete's Training Groups dashboard that automatically calculates an athlete's AeT each week using a four-week moving average of their training data — no field test required. Steve explains the core problem: athletes can do the work consistently and still be uncertain whether they trained at the right intensity, because a missed AeT quietly shifts aerobic sessions into glycolytic territory and derails the adaptation they were after. To validate the algorithm, Steve blind-scored 65 athlete files by hand and found the tool lands within an average of 0.1 beats of his coaching judgment — though that average masks a wider spread, with 62% of athletes falling within five beats and outliers as far as 17 beats off, a gap the team attributes largely to data quality. The episode is candid about where the tool still falls short and what they're doing to close it: improving filtering (wrist-based HR and mountain bike data are particularly noisy), building data-hygiene habits in the community, and targeting 99% of athletes within five beats of coach-level accuracy by year's end.

The Evolution of Testing: Continuous AeT

Steve House welcomes Dr. Øivind Sandbakk, professor at the Norwegian School of Sports Sciences and director of the School for Elite Sports, for a deep dive into the science underlying Norwegian endurance dominance. Sandbakk traces his path from competitive cross-country skier to national-team coach to researcher, explaining that Norway's success stems less from any single training method and more from three decades of shared terminology, systematic data collection, and cross-sport knowledge exchange. He walks through how training intensity distribution is not universal but must be derived from each sport's specific demands — the metabolic fluctuations of skiing, the mechanical load constraints of running, the discipline-specific quirks of swimming and speed skating — and why blindly exporting any one "Norwegian model" misses the point entirely.

The conversation then turns to the practical architecture of elite endurance development: high volumes of low-intensity work as the aerobic foundation, two to three quality sessions per week, and careful load-recovery management where the goal is optimizing adaptation signals rather than executing a plan for its own sake. Sandbakk and House find common ground on the art of coaching — the calibrated gut feeling built from lab data, training diary patterns, and honest athlete communication — and explore muscular endurance, aerobic threshold identification, and the long arc of athletic development, noting that most athletes haven't reached their aerobic ceiling until their early thirties. Sandbakk closes by previewing his current focus on young athlete development, arguing that building complete humans — psychologically resilient, multi-sport, injury-resistant — is the prerequisite for producing world champions.

Building the Aerobic Engine with Dr. Øyvind Sandbakk

(Originally published November 2024, now with new intro from Steve House)  Most of us will never reach the pinnacle of our most passionate pursuit, no matter how driven we are. Through dedication, creativity and ingenuity, our guest today has reached the pinnacle of three of his passions.  Beginning with a unique journey to discover climbing and skiing, then the discovery of an interest in photography, which finally led to becoming a premiere feature and documentary filmmaker, Jimmy Chin has forged his path with resilience, empathy, and a desire to tell important stories.  Jimmy’s accolades and accomplishments speak volumes about a climber and artist who has pushed boundaries and silenced doubters. But it has always been the manner with which Jimmy has achieved that is most impressive. Steve and Jimmy discuss the evolution of his career and the catalyst for picking up a camera in the pursuit of climbing. They dive into the moral qualms Jimmy had shooting Free Solo and how and why he decided to create the award-winning documentary.
