    Going All In on a Marathon Block as a Triathlete | Q&A

    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.

    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.

    Strength and Speed Training Methods of Norwegian Endurance Coaches | Research Roundup

    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.

    Alistair Brownlee, Two-Time Olympic Champion | Everyone Was Surprised by How Slow I Trained

    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 v

    The "Best Practices" We Stand By That the Research Does Not Support

    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. Tapering, torque work, electrolytes, grey zone intervals, heat training, strength training, sprint interval training and psychology. For each one: what the evidence actually says, what the two of them do instead, and the reasoning they would defend it with.

    We Are Nowhere Near Peak Aero | Marc Graveline, Aerodynamics Consultant

    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

    The 10% Rule Applies to Your Long Run, Not Your Week | Research Roundup

    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.

    Physiology Over FTP | Robbie Deckard, Pro Triathlete & Coach

    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.

    The Real Problem With FatMax (It's Not About Carbs vs Fat)

    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
