Joel Filliol, Coach of Seven World Championship Titles: You Need Less Intensity Than You Think
Show notes
Joel Filliol has coached four athletes to seven triathlon World Championship titles: Mario Mola, Vincent Luis, Katie Zaferes and, this year, Vasco Vilaça. On his third appearance on the show we cover how the squad's training has (and has not) changed over a decade of titles, the training week and progressive sessions behind them, how much intensity is actually enough, and how the same principles apply to age-group triathletes on 10 to 15 hours a week.
HIGHLIGHTS AND KEY TOPICS:
• What has and has not changed in the squad's coaching between Mario Mola's first world title in Cozumel in 2016 and Vasco Vilaça's in 2026, from social media to carbon shoes and what they do to run training load.
• The minimal effective dose: whether it applies to intensity or to volume, and how a squad built on doing less can still describe the training as hard.
• The base training week Vasco described on the show in 2023 (six swims, six bikes and six runs), how close it still is, and why the hard sessions are spread across the week rather than blocked.
• How a progressive run session like 16x400 m is prescribed and paced from block to block, and the part of it that has to be held most strictly.
• Mega sessions and confidence: what an outstanding training session does and does not tell you about race day, with Kona as the example.
• How the elite principles scale down to an age grouper with 10 to 15 hours a week, how easy easy training should be, and how to build a sustainable week from scratch.
• The swim rules from Joel's Top 20 Rules for Faster Triathlon Swimming that matter most for age-group triathletes, the readiness and recovery scores he would rather athletes trusted less, and the questions to ask in a season review.
• Vasco's road to the LA Olympics 2028, the Supertri race he turned down this year, and whether a sprint finish against Matt Hauser can be trained, with a lesson from Simon Whitfield's build to Beijing 2008.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Why Being Too Efficient Holds Back Your Cycling | Björn Kafka, Uno-X Cycling Coach
Show notes
How do WorldTour cyclists train across a season, how do you profile a rider and decide what to work on, and what should amateur cyclists and triathletes know about cadence, easy riding and durability?
Björn Kafka coaches for the Uno-X Mobility WorldTour team and has also coached athletes to world and Olympic titles and medals in mountain biking, track cycling, and even snowboarding. He is also a co-developer of the A Faster You platform, formerly Aerotune.
HIGHLIGHTS AND KEY TOPICS:
• Profiling a rider from the power curve: which durations to read, and why a rider can be too efficient in December.
• The off-season plan for the typical age-group triathlete with a low VLaMax and a threshold already close to VO2max, and where cadence and fuelling come into it.
• What a look at 22 masters athletes with unusually high 4 to 5 minute power showed about how much they eat, and the cost of chasing race weight.
• Self-profiling for self-coached triathletes: three test durations, which bike to test on, and why a weak number is not automatically the one to train.
• Inside a WorldTour year: off-season volume, how volume changes before key races, weekly training patterns, and key sessions for GC riders and Classics riders.
• Cadence as a training tool, from fibre recruitment to what it changes for a triathlete who mostly rides steady.
• How easy the easy rides should be, from a GC rider to a punchy rider to an amateur on ten hours a week, and how to fit more volume around work and family.
• Durability: why there is still no good score for it, how to train it, and whether it deserves to be called a fourth performance factor alongside VO2max, utilisation and economy.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Marius Bakken: The Norwegian Method Is Built Around Your Muscles, Not Your Heart
Show notes
Marius Bakken is a physician, a former professional runner and two-time Olympian with a 13:06 personal best for 5000 m, and the person who developed the training approach that later became known as the Norwegian method, since used by Jakob Ingebrigtsen, Andreas Almgren and many others. We cover why he sees the muscles rather than the heart and lungs as the real limiter, how double threshold works, how to find and control your threshold with or without a lactate meter, and how much of it carries over to triathlon.
HIGHLIGHTS AND KEY TOPICS:
• What muscle tone actually is, why it rather than the heart and lungs sits at the centre of how the method builds a training week, and how to palpate your own quads or use a simple morning stair test to track it.
• The weekly template behind the method, why double threshold is treated as one long session with a break in the middle, and why the sequencing of short and long reps matters.
• Finding your threshold with a lactate step test and a follow-up field test, or with no lactate meter at all, and how far below it the training should actually sit.
• Controlling intensity within a 6 x 6 minute session with and without lactate, the RPE that matches the zone, how you should feel when you finish, and the most common way people get it wrong.
• Why total running volume matters for muscle tone as well as running economy, when to split easy runs into doubles, and where strides do and do not earn a place.
• The Saturday X-session, what an Olympic champion hurdler's threshold sessions suggest about triggering the anaerobic system too early, and how a marathon block changes the week.
• How much of this carries over to cycling and triathlon, how the Norwegian triathletes organise their hard days, and what Jakob Ingebrigtsen and Andreas Almgren have added to the method, building upon Marius's work.
• Flat periodisation, fitting the method into a spring marathon build, the final four days before a championship race, and adjustments for beginners, older and female athletes.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Kona Science Special: Humidity, Heat Training and Race-Day Cooling | Research Roundup
Show notes
With the Ironman World Championship in Kona this Saturday, this Research Roundup is a heat and humidity special for triathletes and other endurance athletes, built around four big topics instead of four single studies. How much heat and humidity each slow you down when you separate the two, what the largest reviews say about heat acclimation and whether sauna and hot baths work as well as active methods, how fast heat adaptations arrive and how fast they fade, and which in-race cooling strategies work, while also being practically feasible.
HIGHLIGHTS AND KEY TOPICS:
• Separating heat from humidity: a study that held the vapour pressure of the air constant from 18°C to 27°C and 36°C, then doubled it at 36°C, and why dew point is the number you want to check before a hot race.
• A meta-analysis of 135 studies and 1,531 participants: how short, medium and long heat acclimation protocols compare, and which of four approaches (constant work, isothermal, self-regulated and passive) comes out ahead.
• Sauna and hot baths after training: what a stricter meta-analysis of 10 controlled studies found, why the control groups matter so much, and the case for active heat training when time is short.
• How many heat sessions, how long and how hot: a review of 211 papers, the free online predictor that comes with it, and whether the sessions need to be on consecutive days.
• Five weeks of home-trainer heat sessions in 20 elite cyclists: when haemoglobin mass starts to move, how quickly the gains decay, and how to plan around these dynamics before racing.
• Four days of 90-minute heat sessions: what changed after such a short protocol, why time-to-exhaustion results look so much bigger than time trials, and whether feeling adapted without being adapted could backfire in an all-day race like an Ironman.
• Ice caps, a cooling neck collar, the Omius headband and water dousing in running studies: which ones improved performance, what they did to core temperature, and why Mikael ends up defending a gadget.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

How to Race the IRONMAN World Championship in Kona: A Complete Guide | Tomasz Kowalski
Show notes
Tomasz (Tomek) Kowalski is a triathlon coach with a great track record of athletes racing Kona, among them age-group world champions and podium finishers. With the IRONMAN World Championship coming up again in Kona we cover everything age-group triathletes need to know to have a successful race there, including when to fly out, training and tapering on the island, heat preparation at home, equipment choices, and pacing, fuelling and hydration on race day.
HIGHLIGHTS AND KEY TOPICS:
• The single most common reason a Kona race goes wrong for age-groupers, and roughly how much of the damage it accounts for.
• When to fly out: the time-zone rule of thumb, the trade-off between arriving early and arriving fresh, and whether you need to fully adapt to Hawaiian time at all.
• Training on the island: how much lower your watts and paces can be at the same RPE, how long the last long ride and run should be, and whether to keep touching threshold in the final three weeks.
• Swimming in the last ten days: open water or pool, how to structure an open water session with no buoys to swim between, and how to use the Hoʻala training swim.
• Heat preparation before you travel: a hot water immersion protocol with durations and water temperature, and why using a CORE temperature sensor or sweat testing gets less weight than you might expect.
• Kit for the heat: aero or road helmet, visor or no visor, three headwear options for the run, and whether to change from trisuit to running kit in T2.
• Pacing the swim, bike and run: how many watts to expect to give up compared with a cooler Ironman, and how the impact of the rollers changes depending on how strong a cyclist you are.
• Fuelling and hydration in the heat: the body mass loss on the bike that puts your run at risk, and how easily caffeine intake creeps too high.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Going All In on a Marathon Block as a Triathlete | Q&A
Show notes
Mikael Eriksson and Jack Hutchens answer listener questions, starting with a long look at how to fit a marathon into a triathlon year: when to do it, how much running it takes, what happens to the swim and the bike, and how far the long run really should be. Then questions on racing a 70.3 inside a base phase, coming back from overtraining syndrome, and whether you have to dig a hole to get supercompensation.
We do listener Q&As monthly, the last Thursday every month.HIGHLIGHTS AND KEY TOPICS:
• Where a marathon fits in a triathlon year, autumn against spring, and the one situation where the less obvious option is the right call.
• Setting run mileage when you are also swimming and biking. Why the starting point is your own running history rather than a plan chosen by goal time, and what is wrong with how most marathon plans are built.
• A pro triathlete with a 60-minute record of 400 W at 78 kg asks why a 2:30 marathon still feels far away. What VO2max and fractional utilisation leave as the only possible explanation, and what can and cannot be changed about it.
• Long run distance against total volume, and the main point of disagreement between Mikael and Jack for this episode. Plus how far the longest long run should go, banded by goal time from a first marathon through to sub-2:30.
• Quads as the limiter in the marathon, from a listener with a 1:17 half and a 3:01 Ironman marathon. Conditioning, cadence, shoe drop and fuelling, and which of those actually matters.
• Racing a 70.3 in the middle of a base phase. The question to answer before you decide, and where Mikael and Jack come down differently on treating a race as a training day.
• Returning to training after overtraining syndrome. What to monitor on the way back, why HRV gets less weight here than you might expect, and the case study of a world-class skier who came back from underperformance to the top.
• Whether supercompensation requires digging a hole. Thirty-three trained triathletes, a three-week overload block into a four-week taper, and what separated the group that gained the most from the group that spent the study getting sick.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

David Tilbury-Davis: Everything That Decides Your Results Except the Training
Show notes
David Tilbury-Davis has coached world class triathletes since 1995, among them Lionel Sanders, Ashleigh Gentle, Skye Moench, Cody Beals and Matt Hanson. In this episode we cover everything that decides whether an athlete reaches their potential except the training itself: professionalism, how you design your life around the sport, the decisions you make week to week, psychology and mindset, and the coach-athlete relationship.
HIGHLIGHTS AND KEY TOPICS:
• The single change outside training with the biggest upside, and the second one David adds straight after it, which most athletes with a job will find far harder than the first.
• Professionalism defined as everything that performatively matters and is not swim, bike, run or gym, and the checklist David runs through when he wants to know how professional an athlete really is.
• The difference between a support structure that is supportive and one that is merely tolerant, the conversation to have before committing to a season, and why David wants to interview the 5am-club influencer's partner.
• Guardrails: the training window one of David's pro athletes drew around her day and refused to move, what he tells younger pros about procrastination, and the checks he runs before anyone turns pro.
• Why self-doubt and imposter syndrome run high in almost every athlete he has coached in 30 years, what separates the ones who use it as fuel from the ones it consumes, and where he draws the line between confidence and arrogance.
• Executing a session versus staying present and engaged in it, the athlete riding four hours in ERG-mode watching Top Gun, and the cue David uses for how wrecked a training week should leave you.
• Attention as a resource you spend: structured swim sets on the watch, the athlete apologising for a warm-up five watts off, and the one split David actually wants reported back to him mid-session.
• The 80 / 15 / 5 split David puts on coaching, what falls into the 5 per cent, and the pizza-slice session he invented for one athlete and then wrote to Professor Stephen Seiler about.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Strength and Speed Training Methods of Norwegian Endurance Coaches | Research Roundup
Show notes
In today's Research Roundup we bring you four recent studies. How world-class Norwegian endurance coaches programme strength and speed, the factors determining how a runner's physiology holds up over two and a half hours of running, a defence of the critical power model written by the people who built it, and a polarised versus high-intensity trial in cyclists with a result neither of us expected.
HIGHLIGHTS AND KEY TOPICS:
• Strength and speed training across eight Olympic endurance sports (including triathlon, swimming, cycling and running), from 12 world-class Norwegian coaches whose athletes have won over 400 international medals. How many hours a year each sport does, and which sport sits at the bottom of the table.
• What those sessions look like: exercises, sets, reps and how close to failure the athletes are taken, which is a long way from what randomised trials prescribe. Plus the 10 hours a year of speed training every sport did, and what it looks like.
• How Daniel and Mikael each place strength and speed work in a real training week, where they differ from the Norwegian model, and why an age-group athlete in their forties is a different case from an Olympic athlete in their twenties.
• Physiological resilience (durability) during two and a half hours of continuous unfed running, with thresholds, running economy and VO2max retested at the end. Which variables fall most, which barely move, and how runners of different ability differ.
• Mikael sets the running economy decline against what a pair of carbon shoes buys you and asks which is bigger. Plus the two qualities that separated the runners who held up, one aerobic and one from the gym.
• Ten common criticisms of the critical power model, answered by the group that built it: whether CP is just FTP renamed, whether the model claims you can hold CP forever, whether a power law fits the curve better, and where the authors concede most.
• Critical power as a moving number rather than a fixed one, what that does to how you prescribe a threshold session, and the gap between the test durations the paper recommends and the ones Mikael actually uses.
• Polarised against high intensity with the hard sessions held identical, three a week for six weeks, one group adding four hours a week of easy riding. What the time trial showed, and why Mikael thinks the result is wrong (a strong statement!).SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Alistair Brownlee, Two-Time Olympic Champion | Everyone Was Surprised by How Slow I Trained
Show notes
Alistair Brownlee is the only triathlete to win two individual Olympic golds, winning at home in London in 2012 and in Rio in 2016. He retired at the end of 2024 after an 18-year career, in which he also won two World Titles, four European Titles and the Commonwealth Games. He also has two second-place finishes from Ironman 70.3 World Championships. This is a conversation about how he actually trained across two decades, in particular when he was at his most dominant and changed the sport: the volume, the intensity, what he would do differently, and lots more.
HIGHLIGHTS AND KEY TOPICS:
• Second at Norseman two weeks before this recording, on what he calls zero structured sessions. What has held on, what has gone, and which part of the power duration curve goes first.
• The training week behind two Olympic golds: hours, sessions per sport, the swim, track and bike sessions he built the year around, and what share of it was actually done at intensity.
• Riding at 200 watts with a threshold north of 400, and running five minutes per kilometre when he has a 28:32 PB. Why he was that strict about it, and the two things it bought him.
• High intensity as the icing on the cake: why he thinks the icing contributes less than most athletes believe, and what follows from that if your cake is small.
• His test for whether an easy session was genuinely easy, why feeling hypoglycaemic on an easy ride tells you something, and why he will not give you a wattage or a lactate number for it.
• Injuries, and whether you have to take that risk to win an Olympic title. His arithmetic on what a month lost to injury really costs you, and what that means for today.
• What changes when you have 10 hours a week rather than 35: the one thing he would move about the intensity proportions, and the trap most age group athletes fall into.
• Sodium, cramp and the gap between the literature and what athletes report. Why he is not sold on sweat sodium testing, what heat training did to his own numbers, and the taurine protocol he uses in hot races.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Swimskins, Power Duration Curves and Best Bike Sessions for Runner Turned Cyclist | Q&A
Show notes
Listener Q&A, covering nine different questions/topics from building bike power as a runner and a collegiate swimmer moving back into triathlon, through what actually makes us fatigue during a threshold effort, to swimskins, power duration curves and lots more.
We do listener Q&As monthly, the last Thursday every month.
HIGHLIGHTS AND KEY TOPICS:
• Building the bike as a runner: why heart rate sits lower on the bike than on the run, whether that gap matters, and what it says about where the limiter is. Plus how to use a daily 20 km ride towing a 25 kg dog trailer.
• A 193 cm, 100 kg collegiate swimmer moving back into triathlon: the engine-stronger-than-the-chassis problem, a run progression specified down to the minute, and why Mikael gets more conservative every time he coaches this profile.
• Why the maximal lactate steady state is a steady state for lactate and not for the whole body, what keeps drifting while lactate holds flat, and what one study found when it looked for the system that fails at exhaustion.
• How long you can actually hold MLSS, against the 40 minutes the question assumed, how much that varies between athletes, and where critical power sits relative to it.
• Swimskins: whether they give you any of the buoyancy a wetsuit does, the performance, drag and energy cost numbers from the closest pool research, and the thing that matters more than the brand and price tag.
• Whether a swimskin does more for a fast swimmer or a slow one.
• Reading your own power duration curve with nobody to compare against: the TrainingPeaks chart to start from, why a flat profile means something different for a triathlete than a cyclist, and Strava as a stand-in database.
• Mikael's W’ bands for male and female age group triathletes, on record for the first time, plus the critical power ratio from close to a hundred of his own athletes' tests.
• Quickfire round on altitude, heat and the CORE sensor, run volume by intensity, and vegan nutrition.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

The "Best Practices" We Stand By That the Research Does Not Support
Show notes
Mikael and Jack Hutchens each bring up four things they do in their coaching practice that the research does not support, or does not support in the form they use it. What the evidence says, what they do instead, and the reasoning they would defend it with.
HIGHLIGHTS AND KEY TOPICS:
• Tapering: Mikael prescribes 7 to 10 day tapers where the literature converges on two to three weeks, with a smaller volume cut than the meta-analyses land on. Why he thinks the study populations do not transfer.
• Torque training: Jack keeps low cadence work in every program despite a review finding no strong evidence it improves performance. His specificity case, and Mikael's rationale from the cadence drop late in an Ironman bike.
• Electrolytes: why Mikael prescribes them liberally while accepting the evidence is thin, the one athlete variable no study has controlled for, and the profile that really does not need them.
• Grey zone intervals: polarised training wins the short intervention studies, so why does Jack lean on the zone in between? The time horizon argument, and Mikael's three week VO2max block that stopped working after two.
• Heat training: ten sessions over two weeks for acclimation, five weeks of five for haemoglobin mass, against Mikael's minimal effective dose. Jack's pushback: does half a protocol buy half the adaptation?
• Strength training: where it sits in Jack's list of levers when time is fixed, who he does prioritise it for, and Mikael's rules on frequency, session length and the weekly hours threshold to bother at all.
• Sprint interval training: the protocol with a decent evidence base that Mikael almost never prescribes, what goes in that slot instead, and the cycling study published five days before recording that he never expected to see.
• Psychology: why Jack spends more coaching time on self-talk, goal setting and confidence than the evidence warrants, and Mikael's theory for why it looks so weak in group studies.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

We Are Nowhere Near Peak Aero | Marc Graveline, Aerodynamics Consultant
Show notes
Marc Graveline is an aerodynamics consultant who works with WorldTour cycling teams as well as professional (e.g. Chelsea Sodaro, Lionel Sanders) and amateur triathletes, and road and gravel cyclists. He co-developed the Notio Konect, the first consumer on-bike aero sensor, and now develops his own device, the Gizmo. He also led the testing programme behind IRONMAN's decision to move the professional draft zone from 12 to 20 metres.
We cover how to run an aero test you can actually trust, what to test and in what order, tyres and tyre pressure, and what IRONMAN's draft-zone testing actually found.
HIGHLIGHTS AND KEY TOPICS:
• Why Marc disagrees with the idea that we have reached peak aero, and where he still sees the largest untapped gains across road racing, triathlon and gravel.
• Wind tunnel, velodrome or road: what each venue is good for, why he validates everything on the road, and where an age grouper without an unlimited budget should start.
• Building a road test you can trust: choosing a venue, how long an out-and-back should be, how many repeats, the ABBA protocol, and the single mistake that ruins more test sessions than anything else.
• The hierarchy of what to test, from position down to hydration, and where the biggest gains will come from.
• Why head position drives so much of the result, and why the change you make to your position is often not the thing that actually makes you faster.
• Helmets and skinsuits: which two helmets kept finishing first and second when 21 age groupers worked through a dozen of them at an aero camp, how heat and visibility should be weighed against the CdA number, and how much a custom skinsuit really buys you over one off the shelf.
• Tyres: what WorldTour riders on good roads are actually running for pressure, why erring on one side costs you more than the other, whether wider really is faster, and why a tyre that wins in the wind tunnel can still be the wrong choice for your race.
• The IRONMAN draft-zone testing: the stacking effect that showed up at 12 metres, what changed at 20, what those charts with no y-axis were actually trying to say, and the call to Magnus Ditlev's aerodynamicist that confirmed it in the real world.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

The 10% Rule Applies to Your Long Run, Not Your Week | Research Roundup
Show notes
Daniel Rowland and Mikael are back for another research roundup with four recent studies. What blood biomarkers do and do not tell you about training load in elite triathletes, why two athletes with the same VO2max can have very different thresholds, what actually predicts running injuries in a cohort of 5,200 runners, and whether supersets deliver the same strength gains in a third less gym time.
HIGHLIGHTS AND KEY TOPICS:
• VLaMax (maximal glycolytic flux) and metabolic thresholds: the first evidence in real athletes that at a given VO2max, a higher glycolytic rate means a lower threshold power.
• How VLaMax is measured, why sprint power on its own tells you little to nothing, and whether you can and should measure it and base training decisions off it.
• How much running is too much: in 5,205 runners tracked over 18 months, a single run 10 to 30% longer than the longest run of the previous 30 days came with a 64% higher injury risk, and bigger jumps than that led to injury risk increasing by well over 100%.
• Why the acute:chronic workload ratio and the classic weekly 10% rule showed little or no relationship with injury, and why you should never use the performance management chart for controlling running load.
• Practical long run progression for a marathon or an Ironman, and the one TrainingPeaks chart Mikael looks at more than any other.
• Four seasons of blood urea and creatine kinase in 20 elite (some world class) triathletes: urea tracks training load, CK does not, and a single reading against a reference range means almost nothing.
• Why the ratio of objective to subjective training load may be the most useful signal a coach has, and a heuristic for using it in practice.
• Supersets versus traditional sets: the same strength, hypertrophy, power and body composition gains in 36% less time, 44 minutes per session against 69, and how to apply that to a triathlete's lower body dominant strength programme.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Is optimised workout design pointless (and time in zone what really matters)? | Q&A
Show notes
Mikael and Jack answer listener questions on indoor versus outdoor FTP differences, whether time in zone is all that matters and how to optimise interval intensity, a first 70.3 debrief covering swim breathing problems and bike cramps, and lots more!
Email us your questions, or answer the question prompts in our Instagram stories to get your questions answered on the next Q&A.
HIGHLIGHTS AND KEY TOPICS:
• Why indoor and outdoor FTP differ, whether a 20-watt gap is normal, and why Mikael has never had an athlete test both.
• Fans and airflow as the most underrated indoor cycling upgrade, including the research showing 40 km time-trial power is maintained up to 27°C when airflow matches outdoor riding speed.
• How to back-calculate an outdoor FTP from your own sweet spot and threshold interval data rather than doing a second test.
• Why a 10-minute interval should not be done at your 10-minute power, and how to perform a session so you finish at a session RPE of 7 to 8 with something left in the tank.
• Is time in zone all that matters? The same power and the same total work can produce very different internal loads.
• Minimum rep lengths if you want to spread work through a longer ride: 4 to 5 minutes for VO2max reps, 10 to 15 minutes for threshold reps.
• A first 70.3 debrief: why the swim breathing fell apart and how to break the hypercapnia (CO2 buildup) spiral, and what most likely caused hamstring cramps at 70 km on a hilly bike course.
• Instagram questions: finding your bike power in the first 20 minutes of a race, whether a VO2max block followed by a threshold block is a silver bullet, training after dental surgery, splitting 120 g of carbs per hour, and preparing for the Ironman Nice climb when you have no long climbs.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Physiology Over FTP | Robbie Deckard, Pro Triathlete & Coach
Show notes
Robbie Deckard is a professional middle-distance triathlete and triathlon coach, and the founder of Freaky Fast Aero Accessories. In this episode, Robbie and Mikael dig into the real differences between American and European training methods, using lactate and VLaMax to optimise training and performance, and how age-group triathletes can apply lab-grade thinking to swim, bike and run training without actually going into a lab.
HIGHLIGHTS AND KEY TOPICS:
• The real difference between FTP-centric American coaching and the German/Benelux style built around VLaMax, VO2max and physiological profiling.
• The evolution of VLaMax based training: from Alois Mader's 1970s model through Jan Olbrecht to current day coaches like Dan Lorang.
• Robbie's case for still doing dedicated VO2max work, including a case study that took an amateur cyclist's VO2max from 74 to 87 mL/kg/min over 58 weeks of block periodisation.
• Why building maximal aerobic power early is more valuable long-term than chasing threshold gains, and how that shapes the "durability" that separates junior and U23 cyclists from senior professional cyclists.
• How Robbie profiles athletes using LT1, LT2 and 5-minute power (or 500 yd swim time, or mile run time), and what typical percentage utilisation looks like for age-groupers versus elites.
• How he prescribes endurance, threshold and VO2max sessions in practice, including cues (power, pace, RPE), lactate targets, and why exact wattage precision on threshold work matters less than people think.
• Practical advice for age-groupers: open-water swim skills and ankle-band drills, running road races for pacing and durability, and hill running for strength and economy.
• Improving aerodynamics on a budget: reduce frontal area first, then refine airflow, and how to measure progress without a wind tunnel using Golden Cheetah or a simple speed sensor.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:

Why 90 Grams of Carbs Still Beats 120 | Paul Booth, UTMB-Winning Performance Nutritionist
Show notes
Paul Booth is a performance nutritionist and exercise physiologist who works with elite ultra-endurance athletes and teams, including the Salomon International team, and was the nutritionist behind both the men's and women's UTMB winners in 2025, Tom Evans and Ruth Croft. We cover the science and practice of fuelling: how many carbs you actually need, why the high-carb trend has run ahead of the evidence, and how to get hydration and electrolytes right for triathlon and ultra-endurance racing.
HIGHLIGHTS AND KEY TOPICS:
• Why Paul calls himself a "90-gram carb guy" and where the carb ceiling actually sits
• What the science says about 90 versus 120 grams of carbohydrate per hour
• The physiology of carbohydrate absorption, and how to work out your own intake for an Ironman without lab testing
• Gut training: building tolerance to carbs and fluid in the weeks before a race

Is VO2max more important than lactate threshold? | Research roundup
Show notes
A research roundup episode, where Dr. Gabriele Gallo (of KnowledgeIsWatt) and myself cover four recent research papers and how they might help us train better and improve our understanding of triathlon and endurance performance
HIGHLIGHTS AND KEY TOPICS:
• Do the same training program twice - get different results? (and how Gabriele and I disagree slightly on the conclusions to draw from this study)
• Strength training is beneficial for cycling performance, but how beneficial is it really? And is it beneficial for everybody? Finally, how should you structure your strength training program to make it so?
• A massive review on the impact of different types of endurance training on mitochondrial and capillary growth, and VO2max improvements.
• What separates athletes of different performance levels is not how high they can push their threshold as a percentage of VO2max, but how high the VO2max is in the first place.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:
