That Triathlon Show

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!).

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.

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.

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.

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.
