Ageless Athlete — How to Stay Strong, Curious & Capable for Life

Most of us think aging happens slowly in the background. Dr. Bill Andrews thinks we may be aging faster than we need to.
Bill is a molecular biologist, founder of Sierra Sciences, and a longtime researcher in telomere and telomerase biology. He has spent most of his life asking whether aging itself can be slowed, reversed, or even cured.
He is also an ultra runner. At 74, Bill still runs every day, has completed 100-mile races, and continues to test what the body may be capable of as the decades pass.
This episode is a little different from a typical Ageless Athlete conversation. We talk about running and staying capable, but we also go deep into telomeres, inflammation, mitochondria, gene therapy, supplements, and the future of longevity.
Some of Bill’s ideas are bold, controversial, and still early. I’m grateful to him for being open with his time, his story, and his perspective. Whether you agree with all of his conclusions or not, this is a wide-ranging conversation about aging, performance, possibility, and what it means to keep reaching for a bigger life.

Beth Rodden is one of the most influential climbers of her generation—known for major Yosemite free climbing, multiple free ascents on El Capitan, and routes that helped push standards forward. 
I came into this conversation expecting more about training, aging, and climbing goals. Instead, Beth took us somewhere rarer: the inner work behind the highlight reel. She speaks with a kind of directness that’s almost unfamiliar—about self-doubt, insecurity, injury, and what it feels like to be seen as “strong” while still living a very human life. 
This episode is about the essential skill most people avoid: telling the truth clearly, dropping the performance, and letting your real experience be part of the story—not just the version that looks good from the outside. 
Kyrgyzstan context (mentioned later in the episode): In 2000, Beth was kidnapped at gunpoint in Kyrgyzstan with Tommy Caldwell and two other climbers and held for six days before escaping. 
In this episode, we talk about:
 The “superhuman” myth in climbing—and why it never matched Beth’s lived experience 
 Self-doubt and excellence living in the same body 
 Injury, identity shifts, and what happens when you can’t rely on performance 
 How honesty changes relationships (and what it costs) 
 Why Beth’s story resonates beyond climbing
Beth's authenticity is rare in this world. Don't miss this one!
Don't miss Beth's memoir - A Light Through the Cracks. Highly recommended !

Some guests make you want to train harder. Mike Wardian makes you want to live wider — and stop postponing the things that matter. 
Mike is 52, a runner, adventurer, and lifelong “yes” person. What stood out here wasn’t a race résumé. It was how he builds a life where training fits inside the day, curiosity stays lit, and progress keeps happening even when time is tight. 
Mike’s story has that real-life Forrest Gump energy — he ran 3,200 miles across America on Running Home. But the reason he belongs on this show is the off-camera stuff: burpees while the toast cooks, workouts folded into errands, and the willingness to be a beginner again — whether that’s pickleball, chess, or whatever comes next. 
I’m grateful to Mike for the clarity and humanity he brought to this episode — ambition without bravado, urgency without panic. 
In this episode, we explore
 “Tomorrow isn’t guaranteed” philosophy 
 Training inside real life constraints 
 The 4-part playbook: mindset  / planning / strength / integration
 Humility as a longevity skill 
 Starting > gear, hacks, perfection

Two weeks ago, I attended Vitalist Bay in Berkeley, surrounded by scientists, doctors, founders, and researchers exploring the future of longevity.
A few days later, I was in the Eastern Sierra, recovering from ankle surgery, mountain biking instead of climbing, soaking in hot springs, and thinking about a different side of healthspan: the lived side.
In this solo episode, I share 7 lessons from 70+ athletes on what it really takes to stay strong, curious, and capable over decades. I also included one athlete in his 60s — Greg Benning — because his marginal gains system was simply too useful to leave out.
We talk about:
why small gains compound better than giant reinventions
why rest is not weakness
why curiosity beats comfort
how community supports long-term health
why strength training becomes foundational as we age
what injury teaches us about resilience and identity
how purpose creates energy and vitality later in life
Featuring lessons and stories from Greg Benning, Doug & Joan, Jock Sutherland, Bob Babbitt, Steve Swenson, Jack Tackle, Loree Bolin, and more.

Joe Friel is 82, still training, and still paying attention. In the last five years, he felt the shift—power fading on climbs, muscle disappearing even with a lifetime of lifting—and he’s not sugarcoating what that feels like. 
This episode is about the mistakes that quietly accelerate decline after 50: training like your recovery is unchanged, letting ego run the plan, and waiting too long to adjust. Joe’s approach is simple, honest, and earned—adapt early, stay consistent, and keep your identity bigger than your numbers. 
We talk about
 The first “rules changed” moment: getting dropped on climbs 
 Muscle loss—even with decades of strength work 
 What adaptation without ego actually looks like in real life 
 How to keep training for capability, not nostalgia
Joe, thank you for your time, generosity, and invaluable wisdom!
