Endurance Capital

Welcome back to Endurance Capital.

Most people still measure performance by its peak: the record, the title, the one perfect race. This episode challenges that idea by putting two people in the same conversation who approach human limits from opposite ends.

In 1991, Dr Michael Joyner sat down with a legal pad and a calculator and modelled the fastest marathon a human could run: 1:57:58. The world record at the time was 2:06:50. In April 2026, in London, Sabastian Sawe ran 1:59:30, the first legal marathon under two hours. Thirty-five years, and the lab values of elite runners barely moved. Shoes, pacing, fields and prize money did.

Craig Alexander won the Ironman World Championship three times and the 70.3 World Championship twice. In 2011, at 38, he broke a course record that had stood for fifteen years and became the oldest man to win in Kona. He never had the biggest engine in the field. He was competitive on every test, consistent to the point of being boring, and still on the start line when bigger engines were gone.

One of them defined the ceiling. The other proved that the ceiling is not what wins a career.

This is not just a conversation about marathons and Ironman. It is about limits. Durability. Measurement. Ageing. And why the number that matters is the one you can repeat.

Topics Explored:

- How a seventy-dollar calculator and a legal pad produced the 1:57:58 marathon model, and why it was a question, not a prophecy

- What actually closed the gap to sub-two, and why elite lab values barely moved in sixty years

- The engine you are born with versus the hours you put in, and why most athletes never reach their physiological ceiling

- Why durability, not peak output, is the variable the lab missed

- Goodhart's law, the McNamara fallacy and the tiny margins that decide elite sport

- Which falls first: a women's sub-two marathon or Kona under 7:30

- What will move records in the next ten years

- Inside Crowie's 2011 Kona course record at 38

- Why to be a maximalist, you first must be a minimalist

- What predicts a long life, and what to ignore on your wearable

- Whether long-course racing is good for your health

- What founders, CEOs, investors, athletes and leaders can learn about pacing the decade, not the quarter

🎙 Welcome back to Endurance Capital.

Most people think recovery is about returning to the person you were before.

This episode challenges that idea through the extraordinary story of Jonny Sammut — professional triathlete, entrepreneur, founder of Ogging and Lytework Labs, and a man rebuilding his life after a near-fatal crash at Ironman Western Australia.

Jonny’s accident changed everything in seconds.

He suffered catastrophic injuries to his femur, tibia, fibula and knee. His life was at risk. His leg was at risk. What followed was 19 surgeries, months on crutches, an external fixator and a decision no athlete expects to face: amputate, or fight to save the leg without knowing whether that fight would succeed.

Jonny chose to fight.

But this conversation is not only about injury.

It is about uncertainty.

The psychological weight of living without a promised timeline.

The difference between waiting and rebuilding.

The role of community when progress is slow.

The loss of identity when the old plan disappears.

And what it takes to keep moving forward when no one can tell you what the finish line looks like.

Jonny did not put his life on hold while he recovered.

During the same period, he transformed Ogging from a side project into a growing endurance coaching business and built Lytework Labs, a performance-nutrition company shaped by lessons learned through elite racing.

This is not simply a comeback story.

It is a story about building the next thing when the original plan is gone.

It is about endurance in its most literal form.

Pain.

Patience.

Identity.

Community.

Entrepreneurship.

And what founders, athletes, investors and high performers can learn from someone forced to redefine progress one day at a time. ep-11-rising-above-y-10.txtTXT

🎙 Welcome back to Endurance Capital.

Most people still believe the same lie about elite performance:

that greatness comes from balance.

This episode challenges that idea through the extraordinary career and mindset of Alistair Brownlee — double Olympic triathlon champion, multiple world champion, Commonwealth champion, and one of the defining endurance athletes of his generation.

Alistair did not build his career by staying comfortable.

He went all in.

All in on training.

All in on racing.

All in on standards.

All in on finding out what happens when talent, discipline, risk, and total commitment meet under pressure.

Then he kept testing the edge.

The edge of intensity.

The edge of preparation.

The edge of what the body can absorb.

And the edge between commitment and overreach.

But what makes his story powerful is not only what he won.

It is the way he competed.

The way he raised standards.

The way he made intensity a system.

And the way he approached performance without half-measures.

This is not just a conversation about triathlon.

It is about intensity.

Standards.

Sacrifice.

Pressure.

Identity.

And what it really means to go all in, all the time.

In this episode, we explore:

Why elite performance requires uncommon standards

How Alistair developed his all-in approach to training and racing

What it takes to compete across multiple Olympic cycles

Why confidence is built through preparation, not slogans

How to manage pressure when the outcome matters

The difference between commitment and self-destruction

Why endurance sport rewards consistency, discipline, and suffering well

How to think about risk when the margin for error is small

What happens when intensity becomes part of your identity

Why performance requires both aggression and judgment

What remains after the medals, the races, and the pursuit of peak performance

What founders, CEOs, investors, athletes, and leaders can learn from elite competition

🎙 Welcome back to Endurance Capital.

Most people still believe the same lie about high performance:

that confidence must come before action.

This episode challenges that idea through the extraordinary career and perspective of Chrissie Wellington OBE — four-time IRONMAN World Champion and one of the most accomplished athletes endurance sport has produced.

Chrissie did not build her career through certainty alone.

She built a system.

A system grounded in purpose, preparation, feedback, health, recovery, environment, and the ability to adapt under pressure.

Then she kept learning.

She learned when to push.

When to stop.

Which limits should be challenged.

And which limits protect the foundations that make performance possible.

But what makes her story powerful is not only what she won.

It is the way she thinks about success today.

The medal is visible.

The system behind it is not.

This is not just a conversation about racing.

It is about confidence.

Purpose.

Limits.

Health.

Identity.

And what it takes to build performance that lasts.

In this episode, we explore:

• Why confidence is built through action rather than certainty
• Why the system is the real success
• How purpose creates the foundation for sustained performance
• Why consistency must be combined with agility
• How internal and external feedback improve execution
• The difference between psychological, developmental, and structural limits
• How to know when to push and when to stop
• Why health is the foundation of every performance system
• How environment shapes what becomes possible
• Why identity must remain larger than any single result
• What success means beyond medals and trophies
• Why sustained high performance is a process, not a destination
• What founders, CEOs, investors, athletes, and leaders can learn from elite endurance sport

• Chrissie Wellington OBE
• Four-time IRONMAN World Champion
• Former professional triathlete
• Author of A Life Without Limits

🎙 Welcome back to Endurance Capital.

Most people still believe the same lie about performance:

that excellence belongs to the young.

This episode challenges that idea through the remarkable story of Cherie Gruenfeld — 2025 IRONMAN Hall of Fame inductee, USA Triathlon Hall of Fame inductee, 14-time IRONMAN World Championship age-group winner, 4-time IRONMAN 70.3 World Championship age-group winner, and founder of Exceeding Expectations.

Cherie did not start as a professional athlete.

She came into triathlon around the age of 48, after already building a full life in education and then in the high-tech world.

Then she kept going.

For more than three decades, she built one of the most remarkable age-group careers in endurance sport.

But what makes her story powerful is not only what she won.

It is what the sport allowed her to become.

And eventually, what it allowed her to give back.

This is not just a conversation about racing.

It is about confidence.

Reinvention.

Longevity.

Contribution.

And what it means to build a life that keeps expanding with age.

In this episode, we explore:

Why greatness does not only belong to people who start early

How Cherie entered triathlon later in life and built a 34-year racing chapter

What Ironman gave her beyond medals

Why you do not need to be a professional athlete to build something extraordinary

How confidence compounds through action

What durable weeks, recovery, and planning look like over decades

Why the people around you shape your ability to last

How Exceeding Expectations turns achievement into service

What founders, CEOs, investors, athletes, and parents can learn from late-life excellence

🎙 Powered by the Pack

Crowie Alexander — 3x IRONMAN World Champion | 2x IRONMAN 70.3 World Champion

Support systems, resilience, and the hidden architecture behind long-term performance.

Act 1 — Origin: Who carries you before the wins?

Most people admire individual greatness.

Very few understand what surrounds it.

Not the medals.

Not the finish-line photos.

Not the headline performance people remember.

But the people behind the athlete.

The partner.

The coach.

The training group.

The family.

The co-founder.

The friend who keeps you steady when the result is ugly and the story starts to wobble.

In this episode, Ignacio Garcia sits down with Craig “Crowie” Alexander, one of the most durable athletes in long-course triathlon, to explore a deeper question:

Who helps elite performers stay in the game long enough to become great?

This is not just a conversation about support.

It is a conversation about resilience, loss, recovery, family, coaching, and the systems that keep high performers from becoming isolated under pressure.

Act 2 — The Build: Support, loss & staying in the game

We break down the operating system behind long-term support:

• Why the people who last are often not the most talented, but the best supported

• How Crowie built a world-class career from the outside

• Why family and support systems are part of performance, not separate from it

• How elite athletes learn to lose without losing themselves

• What founders can learn from athletes about building a pack before they break

• Why women’s health, hormones, and internal rhythms matter for sustainable performance

• How coaches, co-founders, partners, and investors shape long-term durability

• What it means to design support by intention, not accident

This episode explores a quieter but more important side of performance:

not the individual breakthrough, but the ecosystem that makes the breakthrough repeatable.

Not the hero story, but the pack behind it.

Not just who wins, but who helps them stay whole enough to keep going.

Act 3 — Translation: The Founder & Investor Playbook

Endurance sport and company-building share the same difficult truth:

you cannot go long alone.

Here is what founders, chief executives, investors, and operators can apply immediately:

Do not confuse independence with durability.

A lot of people can push alone for a while. Far fewer can last that way.

Support is part of the performance system.

The people around you shape your consistency, recovery, decision quality, and resilience.

Get good at losing without losing yourself.

The best performers learn to turn setbacks into data, not identity.

Design your pack before you need it.

Co-founders, coaches, partners, advisors, investors, and friends should not appear only when things break.

The environment matters more than ego admits.

The people who last usually build a system around them that can absorb pressure.

In both sport and business, the deeper question is not just whether you are strong enough to keep going.

It is whether you have built the right support system to make going long possible.

🎙 Built to Last

Daniela Ryf — 5x IRONMAN World Champion | 5x IRONMAN 70.3 World Champion

Standards, sacrifice, and the harder form of excellence: staying at the top long enough to build something that lasts.

Most people admire winning.

Very few understand lasting.

Not one great race.

Not one perfect season.

Not one peak performance people remember forever.

But a career.

A body of work.

A standard held over time.

In this episode, Ignacio Garcia sits down with Daniela Ryf, one of the defining long-course athletes of her era, to explore a deeper question:

What does it take to stay at the top long enough to build something that actually lasts?

This is not just a conversation about titles.

It is a conversation about standards, sacrifice, repetition, and what it means to keep performing when the pressure is no longer exciting, only familiar.

We break down the operating system behind sustained elite performance:

• How to hold a high standard over years, not just races

• Why durability is a harder form of excellence than intensity

• The relationship between ambition, repetition, and structure

• How to keep evolving when everyone is chasing the version of you that already won

• What must be protected if excellence is going to remain usable

• Why the real challenge is not reaching the top, but staying functional once you’re there

This episode explores a less glamorous but more important side of performance:

not the breakthrough, but the maintenance.

Not the rise, but the structure that survives pressure, scrutiny, and time.

Endurance sport and company-building share the same difficult truth:

the challenge is often not getting to the top.

It is staying there without breaking.

Here is what founders, chief executives, investors, and operators can apply immediately:

Do not confuse intensity with durability.

A lot of people can surge. Far fewer can sustain.

Standards matter more than emotion.

What lasts is usually built on repeatable structure, not occasional inspiration.

Success creates a second challenge.

The task is not just reaching the top. It is staying functional once you are there.

What gets protected keeps performing.

Energy, health, identity, focus, and recovery are part of the system, not extras.

A career is a structure, not a spike.

The people who last usually build in a way that survives their own ambition.

In both sport and business, the deeper question is not just whether you can win.

It is whether you can build something strong enough to survive winning.

🎙 The Engine Room for Endurance

Natalie Coles — Supercentenarian researcher | Will Harbourne — Founder & GP, LongGame Ventures

Biological youth vs chronological age. Stress, rhythm, mitochondria, and what the world’s oldest people (supercentenerians) teach us about going long.

Most people say they want longevity.

Very few think seriously about what it actually requires.

Not in slogans.

Not in supplements.

Not in abstract.

But in rhythm.

In biology.

In the systems that let a human body stay useful for far longer than expected.

In this episode, we sit down with Natalie Coles, who has spent years studying supercentenarians — people who live past 110 — and Will Harbourne, investor in lifespan and deep biology, to ask a simple question:

What can the world’s oldest people teach us about staying strong, clear, and functional for longer?

This is not a conversation about immortality.

It is about the long game:

how people age, why some age better than others, and what founders, investors, and endurance athletes can learn from the rare humans who have already stretched the curve.

We break down the operating system behind longevity and preserved function:

• Why supercentenarians often look quieter internally — less stress, less inflammation, more stability

• What rhythm, consistency, and family support have to do with aging well

• Why the microbiome, mitochondria, and immune system matter for both performance and lifespan

• How chronic stress compounds biologically over decades

• Why data and biomarkers matter when used longitudinally, not obsessively

• What normal people can do today before advanced longevity therapies arrive

This episode explores a less fashionable but more useful view of longevity:

not as optimization theatre, but as disciplined biological stewardship.

The lesson is not just to live longer.

It is to stay useful for longer.

Endurance sport, company-building, and healthy aging all reward the same thing:

a system that holds over time.

Here is what founders, investors, and athletes can apply immediately:

Get the basics boringly right.

Sleep, movement, recovery, stress, and metabolic health still matter more than fantasy interventions.

Treat stress as biological, not just emotional.

If you run your nervous system like a war zone for decades, the bill will arrive.

Measure trend, not panic.

Longitudinal biomarker tracking matters more than one dramatic snapshot.

Build the right support system.

Community is not a soft variable. It is part of resilience.

Think in decades.

The long game is not won by intensity alone. It is won by preserving function.

Future therapies may help — but they will reward the prepared.

The people most likely to benefit from the next wave of lifespan tech will be the ones who kept their systems intact long enough to reach it.

In both sport and business, durability is rarely loud.

It is built in rhythm.

In consistency.

In the invisible systems that let you keep going.

🎙 Pain to performance

Mirinda Carfrae — 3x IRONMAN World Champion

Pain tolerance vs system design. The brutal middle. How races and companies are actually decided.

Act 1 — Race Plan: Stakes & Origin

Most people admire the finish.

Very few understand the middle.

The quiet, grinding middle is where races are actually decided — and where most people begin to lose shape, lose clarity, or lose belief.

In this episode, we sit down with Mirinda Carfrae, a female IRONMAN world champion who showed men how to race the marathon with elegance, to explore what happens after the adrenaline fades and before the finish appears.

What matters in that stretch is not noise.

It is not bravado.

It is not a motivational speech.

It is whether pain becomes performance — or failure — depending on the system you have built around it.

Act 2 — The Build: Systems, Stress & Durability

We break down the operating system behind surviving — and performing through — the brutal middle:

• How to stay composed when the race stops feeling smooth

• Why elegance under fatigue is a competitive edge

• The training systems that make pain usable

• Recovery, rhythm, and emotional control under prolonged stress

• How to keep moving when results are still far away

• Why the middle is where belief gets tested, not announced

This episode explores the less glamorous side of elite performance: repetition, patience, restraint, and the invisible systems that allow champions to keep producing when the body is asking different questions than the mind expected. The middle is where durability reveals itself.

Act 3 — Translation: The Operator & Investor Playbook

Endurance and company-building share the same truth:

The real work happens after the excitement and before the payoff.

Here’s what founders and investors can apply immediately:

Respect the middle.

The hardest stretch is often where the advantage is built.

Pain needs a system.

Stress without structure becomes noise. Stress inside a system becomes progress.

Don’t mistake drama for performance.

The best operators often look calm because their process is doing the work.

Build for durability, not just intensity.

Can your pace survive the part nobody applauds?

The long horizon is won in the invisible stretch.

Not at the start. Not at the finish. In the grind.

In both racing and investing, the winner is often the one who stays functional the longest.

🎙 Fluid Intelligence

Mario Mola — 3× World Triathlon Series Champion

Pattern recognition in chaos. Flow as an edge. Smooth execution at race pace.

In short-course triathlon, races are decided in seconds.

A move forms. A wheel is lost. A surge reshapes the field.

There is no time to hesitate.

Only to read what is happening — and respond.

In this episode of Endurance Capital, Mario Mola reflects on what separates strong athletes from world champions: the ability to interpret the race in real time and adapt without emotional volatility.

This is fluid intelligence.

Not rigidity.

Not reaction.

Trained adaptability under pressure.

Act 1 — Race Plan: Stakes & Origin

Mario shares the inflection point in his career when he realized that fitness alone was not enough.

Early on, he tried to impose control — to execute the race exactly as planned.

But elite racing rarely follows a script.

The breakthrough came when he learned to observe first, decide second, and move with precision instead of force.

Fluid intelligence begins with awareness under pressure.

Act 2 — The Build: Systems, Stress & Recovery

We unpack the operating system behind adaptable performance:

• Pattern recognition trained under fatigue

• Staying metabolically calm in chaotic race dynamics

• Practicing variability to prepare for unpredictability

• Executing smoothly at maximum intensity

• Managing cognitive load under sustained stress

Mario explains how elite performers make split-second decisions without panic — and why smooth execution outperforms frantic effort.

Act 3 — Translation: The Operator & Investor Playbook

Markets move like race packs.

Fast. Competitive. Unstable.

The operators who last are not the most rigid — they are the most adaptable.

Three practical applications:
