Steve House sits down with Kyle Lefkoff, a rare figure who has lived at the intersection of serious alpinism and venture capital for nearly four decades. From discovering his "mutant gene" for rock climbing as a kid in Atlanta to surviving K2's deadliest season in 1986, from co-founding Array Biopharma (acquired by Pfizer for $12 billion) to serving as founding chairman of AIARE, Kyle shares how the same principles—luck, timing, patience, and pattern recognition—govern success on both big walls and in boardrooms. The conversation explores his philosophy of "where matters," his belief that geography shapes who we can become, and why he chose Boulder as the terrain where he could develop both his athletic and entrepreneurial potential. Kyle reflects on "Slater's Law" (the climb isn't over until the ropes are on the ground), the parallels between powder days and market momentum, and his ultimate legacy: building bridges—between climbers and guides, entrepreneurs and investors, communities and their mountains.

Nutrition Tips for Athletes: Holiday Edition - Replay

In this episode of the Uphill Athlete Podcast, host Steve House and dietitian Alyssa Leib tackle the challenge of choosing safe, effective supplements in a largely unregulated industry. Alyssa explains that the supplement market operates as "the Wild West" with minimal FDA oversight, meaning products can contain banned substances, heavy metals like lead and cadmium, or nothing at all. She emphasizes the critical importance of third-party testing, recommending athletes look for NSF or Informed Sport certifications to ensure products are safe and accurately labeled.

The discussion covers three essential questions before buying supplements: Does it actually work? Is it safe? Does it fit your budget? Alyssa provides specific recommendations including whey protein isolate over concentrate and creatine monohydrate as the gold standard form, while cautioning that popular supplements like collagen lack strong scientific support for joint health. She stresses that no supplement can replace adequate sleep, proper nutrition, and sufficient protein intake, and advises athletes taking medications to consult pharmacists about potential interactions before adding supplements to their regimen.
