Join 4,000+ athletes, coaches, and everyday winners reading my Substack, where I consistently share conversations like this, along with insights on performance, mindset, and systems for sport, family and life.
This piece comes from a raw, direct, and honest conversation with Joel Filliol.
For me, it goes further back.
I first heard about Joel in 2007. Then his name kept coming up, again and again, when I was in Victoria, Canada, training as a developing elite. He was already deeply involved in the Canadian triathlon system, and through athletes and coaches who knew him, his presence was clear.
📸 - Simon Whitfield and Joel after the Olympic silver in 2008, around the first time I heard about Joel. Simon won Olympic gold in 2000 and silver in 2008. I later had the chance to meet him toward the end of his career in his hometown of Victoria, BC.
I never met Joel back then, but I paid attention to what he was building, and I’ve been following it ever since.
Over the years, I’ve seen his work through the athletes he coached, many of them friends of mine. Some made it to the Olympics. Some stood on the podium.
📸 - Simon Whitfield. That photo was taken at the Victoria, BC airport after his third Olympics in London 2012, where his race ended early following a bike crash that left him with a broken collarbone. Joel came up a few times in that conversation.
For me, what stayed about Joel wasn’t the results, it was what those athletes said about him, the federations he influenced, and the environments he built.
The changes he made in systems, squads, and people. It went beyond performance.
I think Joel is a great coach, not hiding behind data, not chasing trends, but something much harder to find: a blend of human understanding, pragmatism, and real science applied to real people, athletes with dreams, pressure, and lives beyond sport, trying to get better not just in performance, but as humans.
That’s why I’m grateful for his time, and why I wanted to write this.
We discussed:
Coaching
Training
Culture
Zone 1
Athlete development
Leadership
Technology
Self-sabotage
And also why so many driven people (athletes & coaches) keep making the same mistakes.
So let’s get down to it!
PART I: WHAT CHANGED, WHAT DIDN’T
1. The first evolution: triathlon stopped being “three sports”
On Joel view:
If we go back to the early years of triathlon coaching, what people called “good coaching” was often just an improvised combination of swimming, cycling and running knowledge.
You trained with swimmers.
You trained with cyclists.
You trained with runners.
Then you tried to merge it all together and wish for the best.
That was the starting point, and to be fair, it made sense.
Triathlon was still young. The sport had not yet fully developed its own coaching identity. So naturally, people borrowed from the single disciplines.
But over time, coaches started to realize something important:
Triathlon is not simply three sports added together, it is its own discipline. Its own system. Its own load-management puzzle and metabolic and tactical world.
That shift matters.
Because once you understand triathlon as a single integrated system, you stop making one of the most common mistakes in endurance coaching: You stop treating each discipline as if it exists alone.
And this is still a relevant lesson today.
Joel pointed out something very interesting in our conversation.
In recent years, triathlon has seen a return of the single-discipline trend, with more swim specialists, bike specialists, run specialists, and larger multidisciplinary teams coming back into fashion. But the old lesson still applies: if you coach from silos, you can easily create unintended consequences in the other disciplines. What looks like a brilliant decision in one area may quietly damage the whole picture.
That is one of Joel’s core themes: The big picture matters more than the isolated session. Always!!!
2. The digital revolution helped… and hurt
Of course, the sport did evolve in meaningful ways.
Technology changed everything.
Training plans stopped arriving by fax.
Data became easier to collect.
Power meters, GPS watches, heart rate monitors, wearables, cloud platforms, remote coaching systems: all of that made communication between athlete and coach faster, easier, and more continuous.
That is real progress.
The ability to see what an athlete actually did, compare patterns, review execution, and combine objective data with athlete feedback is incredibly useful.
Joel isn’t anti-technology, but he is definitely anti-bullshit.
Because the same technological revolution that improved access also created new problems. When you can measure everything, you also create the illusion that everything measured matters equally.
It doesn’t.
When you can quantify every session, you can also detach athletes from feel. When you can generate endless streams of numbers, you can also drown in noise.
And maybe most importantly, when devices become cheaper and more common, accuracy becomes less guaranteed while confidence in the data keeps growing.
Joel made this point clearly:
In earlier years, calibration and measurement quality were treated more seriously. Now many athletes and coaches trust outputs from black-box systems without asking enough questions.
That is dependency and is dangerous in coaching, because coaching is not the same as data collection.
Coaching is sense-making, judgment and knowing what to ignore.
3. The paradox of modern endurance sport
This is where Joel’s perspective becomes especially valuable, because he has seen both sides.
He has seen the benefits: better communication, more access to data, clearer measurement. But he has also seen the cost… And the cost is not just technical, it’s behavioral.
Athletes now live in a constantly measured world. Every run is tracked. Every ride is scored. Every easy day is visible. Every number can be compared.
And that changes people: how they pace, how they judge effort and how much they trust themselves.
Joel talked about:
Athletes losing something important: the ability to feel effort, to pace instinctively, to know when enough is enough.
Those are not small skills, in endurance sport, they are everything.
So yes, technology improved the tools. But it also made one thing more important than ever: A good bullshit detector.
That line stayed with me, because it applies to much more than wearables. It applies to the entire modern endurance ecosystem: you need a filter, a framework and a way to tell the difference between:
Useful and distracting
Specific and excessive
Scientific and performative
High-level and high-noise
And that brings us to one of the central themes of Joel’s philosophy:
The longer you coach, the less impressed you become by complexity for its own sake.
Because in the end, the goal is:
Not to know more, it is to do better!
PART II: THE PRINCIPLES THAT SURVIVE TIME
1. Deep aerobic conditioning still wins
If there is one principle that runs through almost everything Joel shared, it’s this:
Deep aerobic conditioning still wins: because it gives you options.
A well-conditioned athlete has margin. And we are human, so we should expect errors, not perfect systems.
More ability to recover.
More ability to absorb work.
More stability when life gets messy.
More resilience when training isn’t perfect.
More capacity to race well even when execution is off.
This matters, because too many athletes train as if perfection is required, but sport and life is messy.
Conditioning doesn’t guarantee success, it gives you room to handle imperfection.
That’s the misunderstanding.
Most people think fitness is about how high you can go.
Joel sees it differently.
Real fitness is about how much instability you can absorb without breaking.
2. Consistency beats the “mega day”
We all say consistency matters, almost everyone agrees with that… in theory.
But very few people really train like they believe it.
Joel put it beautifully:
The goal is not the biggest day, but the best average over time. Not the mega days. Not the peak load flex. The average load, repeated over years, is what matters most.
This is where many coaches and athletes go wrong.
They get attached to single moments: big sessions, big numbers, big spikes. But those moments often come at a cost.
What matters more is simple:
Does this session support tomorrow?
And the next day.
And the next week.
And the next block.
And the next few years.
This is not exciting for people chasing instant gratification.
But it is the mindset of mastery, and this is where coaching maturity shows.
Immature coaching celebrates intensity.
Mature coaching protects continuity.
3. Training to train comes before training to win
This may be one of the most valuable ideas in the entire conversation.
Joel said something that should be written on the wall of every endurance coach’s office:
You need to learn how to train before you try to optimize winning.
That sounds obvious, but in practice, most coaches and athletes skip this stage.
They want the advanced sessions, the marginal gains, the race-specific blocks, the performance modeling and the elite details.
All that before they have built the ability to absorb meaningful training load consistently.
Training to train means building the ability to handle frequency, volume, monotony and routine without constant interruption.
It means building the habits, durability, self-management, energy systems, and emotional control required for real development. Without that, higher-level training isn’t possible.
You can try to look serious, but without first learning how to train, there’s nothing underneath to support it and collapse is inevitable.
4. The right load at the right time
Joel’s thinking here is subtle and powerful.
He said, in essence:
Never do today what will compromise the plan tomorrow. We consistently underestimate the cost of what we do today on what comes next.
That is not just a training insight, is a life principle.
The problem with overreaching is not only that it hurts now, the deeper problem is what it steals from the future.
An unnecessarily hard session may not break you today. But it may reduce tomorrow’s quality.
This is why good coaching is rarely about asking, “Can the athlete do this?”
The better question is:
“What is the total cost of doing this now?”
That is a very different lens.
And it is one of the reasons experienced coaches become quieter, not louder.
They understand second-order effects.
5. Iteration beats innovation
This is another principle I loved in Joel’s answers:
Performance improvements mostly come from iteration, not innovation. Endurance sport is fundamentally simple. Keep the main thing the main thing.
This is the opposite of how the modern market sells performance, since the market wants innovation and sells you: a new secret, a new app, a new protocol, a new method and all together with a new identity.
But high-level endurance performance usually comes from repeating what works, adjusting what needs adjustment, and staying on the path long enough for the compounding to matter.
Iteration is not sexy, but it is how real things get built.
You don’t innovate your way out of weak foundations.
You build.
Then refine.
Then repeat.
PART III: WHY ATHLETES KEEP SKIPPING THE BASICS
1. Because complexity sells better than simplicity
Joel said this directly:
Complexity and over-complication sell better than simplicity, even though a simple approach is often much harder to implement in today’s noisy environment.
That sentence could summarize the entire endurance industry, because
Simple training is hard to trust: it’s not sexy, it doesn’t feed the ego, and most people don’t just want progress, they want to feel special, and the market feeds that.
So the markets provides: more gadgets, terminology, fake precision and all the optimization theater
It is easier to sell “special” than “repeatable.” But repeatable is what wins.
2. Looking like a high performer is easier than becoming one
Joel made a very sharp observation in the interview.
Athletes buying the best gear, adopting the appearance of high performance, and behaving how they think top athletes are supposed to behave, before any real work is done. He called part of this dynamic a kind of high-performance cosplay.
That is harsh and 100% accurate, because modern endurance culture makes it easy to perform identity.
You can look prepared, talk like a pro, post like an elite and build an image of seriousness. All that without yet having the internal structure that real performance requires.
This matters because identity can become a trap.
If your main goal is to feel like a serious athlete, you will be tempted to choose what looks serious over what actually builds you.
And often, what builds you is less glamorous.
Going slower
Being more patient
Doing more repetitive work
Being less performative
Because performance it’s built by what you’re willing to repeat when no one is watching.
3. The attention cost nobody talks about
Joel also said something that deserves more airtime:
We all have only so much bandwidth and attention, and focusing on optimizations too early can pull attention away from what matters most.
This is huge, because in modern sport, the problem is often not lack of information, it is fragmented attention.
Athletes want to improve everything at once, and maybe some of those things matter. But not all of them matter equally right now.
A mature athlete, and a mature coach, understand sequence.
What matters now?
What matters later?
What deserves attention?
What is just interesting?
What is actually moving performance?
What is making you feel productive?
That distinction changes everything.
Because progress comes from doing the right things, at the right time, with full attention.
PART IV: ZONE 1 AND THE ART OF GOING EASY ENOUGH
1. Why Joel keeps coming back to Zone 1
Joel has become one of the strongest voices defending the role of Zone 1, and for good reason. His point is not ideological, it is practical.
The goal is to accumulate frequency and volume over time. And the best way to do that is to manage intensity. That is why Zone 1 matters so much.
This is the part many ambitious athletes still do not accept. They keep looking for the hard thing that will unlock performance. But often, the unlock is not another hard session. It is finally learning how easy “easy” needs to be.
Zone 1 it is what allows the rest of the system to function.
It gives you a sustainable base.
It keeps stress manageable.
It keeps frequency possible.
It preserves technical quality.
It supports long-term load.
It reduces the chance that every week becomes a fight for survival.
That is the foundation, not a side issue.
2. Why most athletes get easy training wrong
Joel was very clear here.
Many athletes simply can’t slow down, because of ego, habit, devices disconnecting them from what easy actually feels like, or the belief that easy work is a waste of time.
This is one of the most common self-inflicted wounds in endurance sports.
Athletes say they want to improve long-term, but then they sabotage the exact process required for long-term improvement because they cannot tolerate slow numbers in the short term.
That is not a physiology problem, but a psychology problem. And it is one of the biggest reasons athletes plateau.
Because when easy days become moderate, and moderate days become harder than planned, and hard days stay hard, the whole distribution collapses.
What looked like ambition becomes interference.
3. Why Zone 1 is psychologically hard for ambitious people
Joel’s answer here was excellent.
Ambitious athletes want to make the most of the work. In the short term, faster and harder feel better, more efficient, more validating. They want to improve now, not necessarily in 12 to 24 months.
Ambition is a gift, but unmanaged ambition is often destructive, because it makes patience feel passive, suspicious and long-term progress feel too slow.
And yet, in endurance sport, patience is not optional.
You cannot bully aerobic development, intimidate adaptation or force long-term outcomes by adding more emotional urgency.
The body does not care how motivated you are, iIt responds to load, recovery, repetition and time.
4. How good coaches teach athletes to slow down
Joel’s answer here was not magical, that’s why I liked it.
Trust in the process must be built and continuously reinforced. Orienting the whole process around long-term progression and sustainable accumulation, then reinforcing that through daily planning, communication and objective outcomes over time.
In other words:
You teach restraint constantly, you build a culture around it, reward it, normalize it, explain it, connect it to bigger goals and you keep returning to it.
Most athletes need a new relationship with effort.
PART V: FREQUENCY, VOLUME, INTENSITY
1. The correct order
When I asked Joel to rank frequency, volume, and intensity, his answer was immediate:
Frequency first.
Volume second.
Intensity third.
That order matters.
Frequency comes first because it is the best way to distribute biomechanical load and make work more manageable.
Volume comes next because it builds metabolic fitness and aerobic conditioning.
Intensity comes third because, in endurance sport, it is the least sustainable piece and mostly serves as a finishing touch for race readiness.
This is simple, and most people still reverse it… Why?
Because intensity is the easiest thing to feel.
Frequency and volume are quieter.
They do not announce themselves.
But they are what make the house stand.
2. What people misunderstand about volume
Joel made an important point:
Many people mistakenly believe more volume automatically leads to injury, but if intensity is managed and volume is built progressively through frequency first, it can be built safely over time.
This is an important correction: Volume is not the problem. Poorly managed load is.
And most of the time, what gets blamed on volume is actually an intensity problem.
That distinction matters.
Because athletes who fear volume often replace it with more intensity and then wonder why they keep breaking down.
3. What people misunderstand about intensity
Joel said:
We often overestimate how much intensity is needed, both inside individual sessions and across longer periods. Intensive session volumes are commonly too high, which creates excessive recovery costs and hurts consistency.
This is one of the biggest coaching errors I see too, athletes often do enough intensity to prove they are fit. But not enough to improve appropriately.
Those are not the same thing.
Good training is not about showing what you can survive, it is about giving the body a dose it can adapt to.
The minimum effective dose is not sexy, but it is the way to go. And normally is not achieved by intensity first!
4. The gray zone is not the devil
I liked Joel’s nuance here.
Moderate intensity, the so-called gray zone, can be very useful. It is lower risk than higher intensities and can offer high reward because meaningful volumes can be accumulated there, especially in triathlon-specific contexts.
That kind of answer reflects real coaching, not internet dogma.
It’s not about labeling one zone good and another bad: it’s about dosage.
People want binary answers because they’re easy to repeat.
But real coaching lives in the details
5. Progression without overplanning
Another strong point from Joel:
Building plans week by week, using the upcoming week as the main unit of progression while keeping broader direction in mind. He rarely sketches more than 4 to 6 weeks ahead in detail and prefers to adjust based on actual response.
This matters because it reflects humility, the coach is not trying to look omniscient, he is trying to stay responsive. And this, again, is a larger life lesson.
Rigidity often masquerades as certainty, but adaptability is usually smarter.
PART VI: HIGH PERFORMANCE CULTURE AND DAILY TRAINING ENVIRONMENT
1. Environment beats system
Joel was emphatic here:
The environment is the difference maker. One hundred percent. Not the federation myth. Not the glossy version of “the system.” The real driver is the daily training environment coaches and athletes build together.
This is a powerful correction, because in high-performance sport, people love to worship systems.
Nations.
Federations.
Structures.
Institutions.
But Joel has had visibility into many of them. And his point was blunt, many:
Are far less competent than they appear
Repeat the same mistakes
Lose institutional knowledge
Become bureaucratic
Are successful without fully understanding why
May contain only small pockets of excellence inside much larger noise
That is not cynicism, is experience. And it reminds us of something important:
Real performance is local: built in rooms, on pool decks, tracks, and rides, through honest conversations, repeated behaviors, and strong leadership.
2. What actually makes a DTE world-class
Joel said it starts with leadership.
The coach sets the standard, chooses who fits, structures the training, manages the process, integrates the support network, and shapes the culture. From facilities and feedback loops to physio, strength, nutrition, psychology, logistics, and group standards, the environment must work as a whole.
That’s a world-class daily training environment, not just hard sessions or talented athletes, but full alignment.
What I found especially important was Joel’s point that outsiders often assume having top athletes in the group is enough. It isn’t.
Helping already-good athletes get better is difficult.
Margins shrink.
Pressure rises.
External factors multiply.
A real environment keeps producing improvement across levels, not just one star result.
3. What quietly destroys culture
This section was one of my favorites.
Joel mentioned unmanaged competitiveness inside the group, athletes racing each other in training, people going off-script, interpersonal drama, and hidden dissatisfaction spreading across the environment. All of these can quietly kill performance culture even if training looks good on paper.
That is worth underlining, because many environments fail silently before they fail visibly.
It doesn’t always start with injury, sometimes it starts with ego.
Subtle drift.
Unchecked behavior.
Standards slipping.
Too many “great” sessions that are actually off-plan.
People celebrating what should not be celebrated.
Culture is rarely broken in one dramatic moment, It is usually eroded.
PART VII: COACHING, LEADERSHIP AND THE HUMAN SIDE
1. Coaching is much more than planning sessions
Joel said this very clearly:
The coach’s role goes far beyond planning. It includes supporting the psychological processes around training, building confidence, and dealing with things when they do not go as expected. These soft skills are underrated and under-taught, yet they remain among the most critical differentiators in coaching effectiveness.
This is true far beyond triathlon. The best coaches I know are rarely obsessed with appearing brilliant, they are obsessed with staying useful.
They know when to push.
When to calm.
When to simplify.
When to reframe.
When to say less.
When to stand next to someone and help them not make a bigger problem out of a bad moment.
That is leadership.
2. Confidence without hype
Joel’s answer here was one of the strongest in the interview.
He talked about honesty, about understanding the longer trajectory, and about redirecting attention away from flattering moments toward what is actually meaningful. He emphasized that real confidence comes from process, consistency, and earned execution, not from hype or fragile reassurance.
This is huge, because many athletes are not actually lacking confidence, they are lacking grounded confidence. They want to feel certain before they have earned certainty.
But durable belief is built differently: quietly, repeatedly, through work, through execution and with a string of days that prove something to yourself.
That kind of confidence survives pressure.
3. What champions do differently
Joel highlighted several recurring patterns in champions:
Self-management, attention control, ego regulation in training, and an intuitive sense for when enough is enough. They do not need external structure to the same extent, and they do not waste energy trying to win every session.
I love that framing, because the outside world often sees champions as extraordinary in dramatic ways. But internally, they are often extraordinary in quieter ones. They:
Manage themselves
Stay on task
Protect attention
Regulate emotion
Keep the main thing the main thing
That doesn’t sound flashy, but it wins!
4. The dark side of talent
Joel was also very honest about self-sabotage.
He mentioned ego loss in training, novelty-seeking, poor communication around niggles, trying to do everything at once, social media distraction, short-term thinking, and optimizing for comfort instead of confronting difficult truths. He said talent is rarely the limiting factor; usually one or several of these patterns sit between a talented athlete and their potential.
This should hit home for a lot of people, Because sometimes what limits us is not lack of knowledge, it is once again lack of restraint, or lack of honesty, or lack of patience.
The very traits that make someone driven can also make them fragile if they are not guided properly.
PART VIII: THE INDUSTRY, THE MARKET, AND THE NOISE
1. The endurance industry rewards the wrong things
Joel’s critique here was sharp and necessary.
He described the biggest shift as short-termism, driven by social media and by a commercial ecosystem that profits when athletes feel dissatisfied enough to keep buying new solutions. Long-term development is slow and hard to monetize; short-term visible results are much easier to package and sell.
That is a brutal sentence and true, because the market does not reward patience very well. So athletes get pushed toward decisions that look active but undermine long-term development.
This is why so many people feel busy but under-built.
2. Complexity has become a product
This may be one of the most important lines in the whole conversation:
Complexity itself has become something the industry sells. Making simple things appear difficult to navigate creates demand for tools, experts, and systems, even when the core drivers of performance remain relatively straightforward.
This is the modern trap, simple is often treated as naive and complex is treated as advanced.
But in many cases, complexity is just a business model, and real coaches have to protect athletes from that.
3. The problem with marketing-first coaching
Joel was direct here too.
He said the rise of marketing-first coaching has done genuine damage because the things that truly work are hard to sell: patience, consistency, doing less but better, and saying no more often than yes. Sexy solutions beat sound fundamentals in an attention economy.
That is one of the clearest summaries of the current coaching world I have heard, and it should make athletes more careful.
Because online polish is not the same as coaching depth.
The ability to make everything sound advanced is not the same as the ability to guide a human being through multiple seasons of development.
4. AI and the future
Joel is not naive about what is coming.
He believes tools for filtering data and spotting patterns will improve, but he also warned that AI will commoditize basic programming and generic guidance, while over-reliance on algorithms may weaken the very human pattern-recognition, sense-making, and relational skills that coaches need most.
I think he is right, and I think this applies outside of coaching too.
The more the world automates ordinary outputs, the more valuable deep judgment becomes. And judgment is not built by outsourcing observation, it is built by paying attention.
PART IX: SWIM, BIKE, RUN AND INDIVIDUALIZATION
1. Swim: conditioning first
Joel’s swim views are refreshingly practical.
He said conditioning-first is controversial because many people over-focus on technique, especially in triathlon populations who often start with limited swim history and limited time. Technique matters, but without conditioning you cannot maintain good technique for long. The two are linked.
That is a useful reminder, because many triathletes hide inside the idea of technique.
Sometimes because it feels technical.
Sometimes because it delays the harder truth: You may simply need to swim more often and build real swim-specific conditioning.
2. Bike: modern racing is more stochastic and more skill-dependent
Joel pointed out that draft-legal racing now demands much more skill: technical courses, repeated accelerations, over-threshold efforts, positioning, cornering, and the ability to recover from high surges. But all of that still depends on fundamental threshold and conditioning underneath it.
Again, same pattern: skills matter and specificity matters.
But none of it excuses weak fundamentals.
3. Run: durability is still the game
Joel’s view on triathlon running is very clear: good triathlon running is pre-fatigued running, so durability, conditioning, and the ability to run well under prior load are central. Long-course athletes need strong long runs and runs off the bike; shorter-course athletes still need enough longer work and moderate-intensity volume inside longer runs.
No surprise here.
The body still has to carry the truth.
4. Juniors, elites, masters
Joel’s principles across levels were grounded and humane.
For juniors, the long-term view matters most: health, enjoyment, proper progression, avoiding premature competition escalation, and avoiding excessive load too early. He noted the massive dropout rate from top junior levels and reminded us that triathlon is a late-maturation endurance sport.
For athletes moving from amateur to pro to world-class, the pressure and identity demands change, and “training to train” often takes much longer than people expect.
For master athletes, life load becomes crucial. Joel emphasized balancing sport and life stress, managing expectations honestly, and orienting more toward self-improvement than pure outcome-chasing.
That is real coaching:
Different people.
Same principles.
Different dosage.
Different context.
PART X: WHAT A GOOD COACH REALLY IS
Joel’s answer to this was excellent.
Good coaching is about connection, understanding where people are coming from and where they are trying to go, helping them improve over the long term, helping them avoid preventable mistakes, and leaving them better not only as athletes but as people.
I would add this: A good coach is not just someone who can help you go faster, is someone who reduces unnecessary variables. Someone who:
Helps you stay on the road
Can see around corners
Can hold perspective when you lose it
Does not use your ambition against you
Joel also warned against red flags:
Coaches who are always chasing the latest trend, leaning heavily on buzzwords, building a superficial technology-based image of expertise, or making relatively simple things appear unnecessarily complex. He also made the point that long-form content often reveals whether someone’s understanding holds up under scrutiny.
That is such a valuable filter, depth reveals itself over time, so does bullshit!
And when athletes choose a coach, Joel suggested looking for breadth and depth of experience, evidence of real performance improvement over time, suitability to the athlete’s context, and above all, the ability to communicate and build a relationship. He also emphasized that high-level coaching is very difficult to scale because time, attention, and communication are core to the process.
Because in a world of scale, coaching remains stubbornly human.
PART XI: THE MASTERCLASS
This is the part you can use.
Today, right now.
Without needing a new app, a new method, a new identity, or a new excuse.
1. Build the aerobic engine first
Deep aerobic conditioning creates resilience, recovery capacity, and options. It is not one part of the system. It is the base of the system.
2. Choose the best average, not the biggest day
Stop chasing the mega session. Train in a way that supports tomorrow. And the day after. And next month.
3. Learn how to train before trying to optimize winning
Training to train comes first. Build capacity. Build durability. Build routine. Build absorption. Then refine.
4. Treat intensity like a tool, not a personality
Too much intensity remains one of the biggest mistakes in endurance sport. Respect its cost. Use it precisely.
5. Protect Zone 1
Easy enough means easy enough. Most athletes are not under-doing their easy work. They are overdosing it.
6. Use the right order
Frequency first. Volume second. Intensity third. Not the other way around.
7. Think in systems, not silos
Swim affects bike. Bike affects run. Training affects life. Life affects training. Everything touches everything.
8. Build the environment, not just the program
Culture matters. Leadership matters. Group behavior matters. What you celebrate matters.
9. Coach the person, not just the physiology
Confidence, fear, ego, patience, honesty, attention, identity: these shape training as much as wattage does.
10. Filter the noise
Just because something is measurable does not mean it is meaningful. Just because something is popular does not mean it is useful. Just because something is complex does not mean it is superior.
11. Avoid self-sabotage
Most talented athletes are not held back by lack of possibility. They are held back by poor restraint, distraction, novelty-seeking, hidden ego, and short-term thinking.
12. Keep the main thing the main thing
This may be the whole article in one line.
My final thoughts
What Joel shared with me is not a method, it’s a way of seeing the work.
A way to coach, to think, to filter what matters… and to stay grounded in a space that constantly pushes for more.
That’s why it stands out, because it goes against the current.
The market wants more. Joel points to enough.
The market wants complexity. Joel goes back to basics.
The market wants speed. Joel builds over years.
The market wants the image. Joel focuses on the work.
That’s where the depth is—not in adding, but in protecting what works and removing variables, just like all high performers I know do.
After all the data, noise, trends, and performative science, it still comes down to one question:
Can you do the basics well enough, long enough, with enough discipline, to let time work for you?
The answer is yes, but only if you stop interrupting the process.
Stop trying to look advanced before you’re durable.
Stop using intensity as proof.
Accept that the highest levels are built on things that feel almost too simple.
That’s the challenge, Because simple doesn’t feed the ego, but simple, done well, builds mastery.
Thank you, Joel for the clarity and for protecting what matters.
There’s a lot here to carry forward.
Have a great week 🤙🚀

This is so, so, good! I have been coaching triathletes for 26 years, so I found myself nodding along. I always thought I would write down what I learned from my 26+ years of coaching when I retire, so I'm impressed by how cogent this is. Thank you for this.
My man! This is one of the best posts you've shared (a high bar). There's so much to go into. It's like a manifesto on being an athlete, being a coach (and being coached).
I think, that the biggest takeaway for most is:
"Avoid self-sabotage
Most talented athletes are not held back by lack of possibility. They are held back by poor restraint, distraction, novelty-seeking, hidden ego, and short-term thinking."
I think to all the people I talk to (especially myself), it's always been this little line that undoes the work (not yet on this journey but the battle is ongoing!)
I come away after reading that amped for training, simple, consistent training.
