That Triathlon Show

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 A simple DIY method to work out your sweat rate and fluid needs Why hydration, not carbs, is behind most race-day gut problems Electrolytes: what the evidence supports and what is mostly marketing Fuelling through heat, altitude and ageing, plus listener questions on glycogen-depleted training, honey and more SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES: Follow Paul and Performance Gains Nutrition on his website and Instagram The shownotes for today's episode can be found here.

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:  Follow Gabriele and KnowledgeIsWatt on his website, Substack and Instagram The shownotes for today's episode can be found here.  The full podcast episode archives (including category filters) can be found here.  Limited reproducibility of individual physiological adaptations to repeated endurance exercise training - Odden et al. 2026 Heavy strength training effects on physiological determinants of endurance cyclist performance: a systematic review with meta-analysis - Llanos-Lagos et al. 2025 Effects of Exercise Training on Mitochondrial and Capillary Growth in Human Skeletal Muscle: A Systematic Review and Meta-Regression - Mølmen et al. 2024 Elite Aerobic Endurance Performance: Is It Really Related to Lactate Threshold Expressed Relative to Peak Oxygen Uptake? - Johansen et al. 2025 Strength training improves performance

Kolie Moore of Empirical Cycling returns to That Triathlon Show! In today’s episode Kolie brings lists of his top underrated and overrated factors for cycling performance to the table, and we discuss these. Kolie also tests Mikael on logical reasoning, and has him guess whether each factor is overrated or underrated on Kolie’s list. HIGHLIGHTS AND KEY TOPICS:  Kolie’s top underrated and overrated factors for cycling performance Without specifying which categories each of these belong in, some of the things we discuss include creatine, Zone 2 training, training plans, race specificity, and many more!  What factors did Kolie overrate or underrate earlier in his coaching career?

Today we discuss how to execute your best possible race day performance. Mikael and Jack provide practical tips that you can apply from sprint distance triathlon to the Ironman. Some of these tips are probably familiar (but bear repeating), others you have likely never heard or thought of before.  HIGHLIGHTS AND KEY TOPICS:  Proper pacing across swim, bike and run in a triathlon Why you should use RPE as the primary driver of pacing strategy Known and lesser-known tips for maximising speed across the swim and the bike Is “run for dough” still true in triathlon? Managing the heat in hot races Nutrition and hydration - more than just having a plan, it’s about understanding how to adjust the plan on the fly when needed. How to get the most out of yourself mentally - the brain is a central governor, so if your head is not in it, you won’t have your best race. But getting your head to be in it and stay in it is easier said than done. DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

If you are focusing on improving your FatMax in 2026, you’re likely wasting time and money. Not only is fat a more expensive substrate to burn than carbohydrate (you get less energy for the same amount of oxygen by oxidising fat), but the Fatmax number you see in your lab report is mostly noise and very little signal.  In today’s episode of That Triathlon Show I’ll explain exactly why that is, but I’ll also give you a tool to evaluate any test or measure that you might (or might not) want to be tracking, from Time Trials to VO2max, HRV and various biomarkers like ferritin and testosterone.  HIGHLIGHTS AND KEY TOPICS:  What is Fatmax and Maximal Rate of Fat Oxidation? How reliable is Fatmax testing? How to measure the noise of a test using the Coefficient of Variation (CV) How to calculate the Smallest Detectable Change (SDC) of any test or measure Why the SDC of Fatmax is the equivalent of you having to go from 300 to 384W for your 20-minute power to be able to say that this was real improvement and not just noise (!!) CVs and CV ranges for common tests and measures used in triathlon, Ironman and other endurance sports, including Time Trials, Time To Exhaustion, VO2max, lactate and ventilatory thresholds, economy and gross efficiency, lactate concentration, Critical Power and W’, HRV, ferritin, testosterone, TSH and more Why carbohydrate is a 7% more efficient energy substrate than fat, and why you should be oxidising carbs in your next Ironman.

Most triathlon training focuses on physiology and skills. Dr. David Spindler argues that the brain is the missing piece, and that you can (and should) train your brain to better process pressure, adapt under stress, and execute under fatigue. This episode will teach you how to do this. Dr. David Spindler is a neuroscientist and cognitive performance specialists who has worked with athletes at the very highest level (including with Sir Mark Cavendish, Sam Laidlow, Chelsea Sodaro, Katie Courtney, and Tom Evans) and across sports from cycling, triathlon and trail running through soccer and Formula 1.  HIGHLIGHTS AND KEY TOPICS:  The brain's central role in athletic performance: coordination, decision-making, focus, emotional regulation, fatigue perception, and recovery. Allostatic load: why amateur triathletes carry far more cognitive stress than professionals, and how to account for it in training. How the brain controls pacing, and why perceived effort rises and the efficiency of firing muscles drops when the brain decides an effort isn't sustainable. Self-efficacy vs. confidence: why they are different, and how to address a lack of self-efficacy as a triathlete. Self-regulation: why understanding how your brain and body behave under stress matters, and how poor self-regulation undermines both triathlon training and the athlete-coach relationship. Joy and happiness as recovery tools: why they are the most effective mediators of cortisol, and how to find joy and happiness in training and life (it’s not the same as dopamine hits) DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

In this episode, coach Daniel Rowland and myself each bring two recent research studies to the table that we have found interesting and potentially useful for athletes and coaches. We discuss the implications and practical takeaways of the findings, how athletes can implement the findings in practice, and the strengths and weaknesses of the different studies. Whether you listen for the love of endurance sports science, or because you want to keep up to date with the cutting edge in triathlon training, this one is for you.  HIGHLIGHTS AND KEY TOPICS:  A study looking into two types of torque training: very short maximal effort low-cadence sprints, and classic four-minute torque intervals just below Critical Power. Does ketone ester supplementation have direct performance-enhancing benefits? How age-group triathletes actually carb-loaded before the Ironman World Championships - did they hit the optimal amounts of carbohydrates or not?

This is the episode for every triathlete with ambitions in sprint and Olympic distance triathlon, from beginners looking to complete to front-of-the-pack athletes looking to compete. Triathlon training has similarities across the board from sprint to Ironman distance, but the specific training obviously differs between distances, and in this episode we break down exactly, when, why and how. Let’s get stuck in!  HIGHLIGHTS AND KEY TOPICS:  How long does it take to prepare for a sprint or an Olympic distance race if you’re a beginner? What about an intermediate to advanced triathlete?  Key sessions in swimming, cycling and running for sprint and Olympic distance triathletes How long should your long run and ride be as a sprint or Olympic distance triathlete?  What role does brick workouts play in sprint and Olympic Distance triathlon training?  Why tapering is much harder to get right for shorter than for longer races, and how to actually do it.  Key considerations if you’re racing draft-legal rather than non-draft sprint and Olympic distance races Sample training week for an Olympic distance triathlon Listener questions!  DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

For many years, the topic of whether a polarized or pyramidal training intensity distribution is more effective for endurance athletes has been hotly debated. Arturo Casado, PhD, is one of the foremost researchers in this area (and former European Champion in the 1500 metres). Today, Arturo dissects what the science really says in 2026: whether there is a winner, and if not, what are the athlete-specific, event-specific, and other variables that impact which training distribution will bring the best results. We also discuss specific training models from Canova to Norwegian from both scientific and practical perspectives, and bring it all together with practical advice relevant for amateur triathletes and runners.  HIGHLIGHTS AND KEY TOPICS:  The science and practice of training intensity distributions. Who should use polarized versus pyramidal TIDs and when?  How do factors such as athlete level, age and sex, sport or modality, distance or event, periodization and more impact the choice of training intensity distribution? The science and practise of different training models in distance running, including Lydiard, Kenyan, Canova, Norwegian, Coe and more How do best practices differ between amateur athletes and elite runners and triathletes?   Practical tips and takeaways DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

Triathlon is a sport that rewards a big aerobic base, built over multiple years (if not decades) of training. But even though we all know this, it’s often hard in practice to prioritise this kind of long-term aerobic development, and we make tradeoffs that might lead to short-term gains, but might not help us achieve our full potential in the long-term. Coach Carson Christen joins me today to discuss this topic in detail. By the end of this episode you should have a better idea of what you can do today, this month, and this year, to maximise your long-term development as a triathlete. HIGHLIGHTS AND KEY TOPICS:  How many lifetime training hours do you need to get close to (90% of the way there) your full triathlon potential?  How age-group triathletes should adopt a more long-term focused mindset to their training with this in mind What is the role of intensity when it comes to long-term aerobic development?  Do swimming, cycling and running require different approaches to maximise long-term development?  Common mistakes age-group triathletes and triathlon coaches make that might lead to short-term gains while limiting long-term potential Practical tips and takeaways DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

Innovations like the aerobar, power meter and GPS watches have shaped triathlon and endurance sports in the last decades. But what comes next? What will be the next big innovation to shape triathlon? Dr. David Lipman returns to the podcast to discuss what the next big innovations will be, and which ones might fall flat. We also take a stroll down memory lane to look at past innovations that succeeded and failed, and try to parse what it takes for an innovation to really stick.  HIGHLIGHTS AND KEY TOPICS:  Past innovations that succeeded and failed - David and I list five each from both categories. Do you agree with our takes here?  We predict the future of current or “coming soon” innovations. Will technologies like continuous sweat sensors, ventilation sensors, 3D-printed running shoes and many be huge hits or will they flop?  Where were we right and wrong in the past? We each name one innovation that  we called correctly (as success/failure) and one that we called incorrectly in the past What separates successful innovations in endurance sports from failed ones Why many promising physiological sensors struggle to achieve widespread adoption despite valid scientific rationales How network effects and ecosystem adoption influence technology success DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

We’re tackling a heavily requested topic today: triathlon training for masters athletes. Is it possible to slow down the natural performance decline through better and smarter training and recovery? Might you even be able to reverse time and hit new peaks later in life? Mikael Eriksson and Jack Hutchens discuss best practices for older athletes based on their coaching experience and the scientific literature. HIGHLIGHTS AND KEY TOPICS:  The science of physiological and performance decline with age in swimming, cycling, running and triathlon VO2max, strength, muscle mass, fast twitch fibre atrophy, slower recovery, and other factors How to tease apart the inevitable decline due to biological processes, and the decline resulting from changing training habits for older triathletes The importance of VO2max training, and how to structure it differently for masters athletes Strength training as a critical component of triathlon training for masters athletes How recovery, nutrition, and sleep needs change with age Examples and case studies Listener questions Practical takeaways DETAILED EPISODE SHOWNOTES:  We have detailed shownotes for all of our episodes.

Physiological profiling is often the missing link in amateur triathletes’ training programs. Knowing your profile on a scale from very endurance based (slow twitch phenotype) to very explosive (fast twitch phenotype) can help you avoid costly mistakes and break through plateaus in your triathlon training through better individualisation. In this episode, we discuss the ins and outs of this topic, from how to correctly profile an athlete without misinterpretation or overinterpretation, to important training implications for different athlete profiles.   HIGHLIGHTS AND KEY TOPICS:  What is physiological profiling? Different methods, including race performance assessments, power-duration curve, Critical Power testing, psychological factors, and more… What are the main differences between fast twitch dominant profiles and slow twitch dominant profiles, and why does it matter for your triathlon training program? Training implications for different profiles: intensity, volume, session structures, nutrition, rest within and between sessions, fatiguability, and more How to deal with different profiles in a group training setting Practical takehome messages that you can use to improve your triathlon training.

Torque and cadence are common features of cycling training programs, but how should you really train them to get the most out of your training? Peter Leo is a sports scientist and high-performance coach working across cycling (Team Jayco-Alula, Cycling Australia) and triathlon (coach of high-level short-course athletes), and since he’s personally researched this topic, and applied it at the highest level, he’s a perfect guest to answer this question. We also discuss training principles, including debunking some common misconceptions and mistakes made when applying training principles in practice.  HIGHLIGHTS AND KEY TOPICS:  The science behind the torque-cadence relationship Torque and cadence are performance limiters at different points on the power-duration curve Practical application of the science in different contexts (track and road cycling, short and long course triathlon), including specific workout examples Peter’s view on three core training principles… Individualisation. What are the biggest factors behind needs to individualise training? Is individualisation overrated in certain contexts? Specificity. Is there an over emphasis on race specificity, compared to maximising core physiological capacities and general skills? Progression. What does effective progression really look like in triathlon and cycling training? Are amateur cyclists and triathletes adopting too aggressive progression rates?

Most triathletes are limited not by their physical capacity to train more or harder, but by being time-limited, so we’re constantly looking for ways to make more out of the time we have to train. Nowhere is this challenge greater than when training for Ironman or other full distance triathlon races on a limited time budget. In this episode, coach Natasha Van Der Merwe joins me to discuss how to deal with this challenge in the context of age-group triathlon training. HIGHLIGHTS AND KEY TOPICS:  How to maximize your triathlon training outcomes on a limited time budget - even if you’re training for an Ironman!
