April 02Triathlon Training for Masters Athletes - Maximise Performance in Your 50s and Beyond
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. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes.

March 26Cycling Training for the WorldTour and for Age-Group Triathletes | Jacob Tipper (coach of Ben Healy and Lucy Byram)
Jacob Tipper is a high-performance cycling and triathlon coach working with athletes such as Ben Healy (Tour de France stage winner and UCI World Championships third place in 2025), Lucy Byram, Dan Bigham and Jonny Brownlee. He is also a team coach or the EF Education-EasyPost WorldTour team. In today’s interview we discuss training for amateur triathletes and we dive deep into Ben Healy’s training and preparation that led to his breakthrough year in 2025.
HIGHLIGHTS AND KEY TOPICS:
Jacob’s thoughts on doing aerobic runs at a decent clip to optimise biomechanical development and running economy improvements.

The key characteristics of Ben Healy’s training in 2025

Being a high-volume athlete on an annual basis without having very high weekly training volumes.

The changes in race tactics Ben implemented in 2025 to be able to win races at the highest level.

The differences between the scientific literature’s view of cycling training and what it actually looks like

How age-group triathletes should think about volume and intensity as drivers of adaptation when it comes to their cycling.

How to maximise training return on investment for time-crunched athletes by not following rigid rules

Monitoring training improvements by feel

How working on speed as the ultimate training metric is still important and still underestimated.

Periodisation - science and practice.

How to implement block periodisation in your training program.

Sebastian’s approach to ultra-endurance training, with an extremely high proportion of low-intensity training

Threshold training - science and practice

Why Sebastian mainly prefers other intensities than threshold training in his coaching

The myth of “active recovery”

March 05Physiological Profiling Explained - Why, How, and Important Training Implications for Triathletes
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.
DETAILED EPISODE SHOWNOTES:
We have detailed shownotes for all of our episodes. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes.

February 26The science of cadence, torque and power in cycling performance | Peter Leo (Team Jayco-Alula)
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?

Evaluating response to training, AI and coaching, and Peter’s top tips for the listeners to improve their cycling and triathlon performance.

February 19How to Optimize Your Triathlon Training on a Limited Time Budget | Natasha Van Der Merwe
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!

How do you know when you’re really just limited by time and training volume?

If you are volume-limited, how can you get around that when you don’t really have more time to spare.

Listener questions: effective microcycle structures in triathlon, how to become more efficient at training, and more

February 12How to avoid triathlon and running injuries by optimising training load, life stress, strength training and nutrition | Chris Johnson PT
Most triathletes and runners will suffer from injuries almost every single year (and many will suffer multiple injuries per year). In this episode, world-renowned physical therapist Chris Johnson explains how to break out of this injury cycle, by looking at all of the different variables contributing to injuries. This is an in-depth look at how to balance your running or triathlon training with proper strength training, nutrition, and lifestyle factors, to allow you to train and perform more and better in the long run.
HIGHLIGHTS AND KEY TOPICS:
Which factors contribute to injuries and injury risk, and how?

How to manage small niggles, aches and pains

Bone stress injuries and soft tissue injuries

Return to training protocols

A minimal effective dose strength training protocol that can be easily combined with triathlon training

Recommended strength training exercises, from isometrics and heavy slow resistance training to plyometrics

How heavy should you lift and how hard should you be working in the gym?

Is stretching, mobility work, massage and manual therapy recommended for injury prevention?

Myths and misconception about injuries and strength training for triathletes and runners

TOPICS COVERED IN THIS EPISODE:
Mikael’s favourite Fartlek run
