The Physiology of Endurance Running Podcast – Détails, épisodes et analyse

Building on a very popular Twitter thread (https://x.com/Dan_Nash94/status/1797744471565574604),Dan & Owain discuss marathon pacing.

First, an overview of some of the physiology that you'll be contending with during a marathon - especially if you go out too fast!

Dan & Owain then discuss the pacing plan Dan has utilised in recent marathons, and how you could go about doing the same yourself.

Let us know if you've used a similar physiological anchoring method for a marathon and how you got on!

Owain is also recruiting for a research study looking at hot baths and EPO, which will be a future podcast topic too - if you're interested in taking part more information is here: https://many.bio/EPOStudy

In this episode, Dan and Owain explore the research on the supplements and accessories that have recently been hitting the headlines.

They share what the research has to say on their effectiveness including, who may benefit the most, the risk-reward ratio, and advice on implementation strategies.

Dan finishes the podcast with a plug of both the Sport Physiology Hub, and his new online coaching offer. If you are interested in one of the five coaching slots that Dan has available, then introduce yourself via email ([email protected]), including a description of your training background and upcoming goals. The deadline for emails is September 1st.

Is threshold training old news? Should we all be following the "American Method"?

Dan & Owain talk through the mens 1500m Olympic final; how the race played out, what training is best to run a championship 1500m, will we see a shift of training methods in the next 4 years.

What did you think of the 1500m final, and the rest of the Olympic events?

Do you use threshold training yourself?

In this episode Dan & Owain discuss the physiology of the warm up.

For many runners, a warm up features some jogging and possibly a few strides. But the warm up of a professional runner differs significantly, due to some interesting research into what is often referred to as "priming".

Dan & Owain discuss some of the history of the research, the physiology of "priming", and offer some practical applications that you can try before your next session or race.

If you give priming a go, let us know how you get on!

Welcome back! Dan finally feels like he has the time to relaunch the pod and is joined by new co-host, Owain Zerilli. In this episode, we delve into all things "easy running". We started with defining what easy running is from a physiology perspective, before going into describing what benefits we can (and can't) expect from training in "zone 2". We finish by looking at the bigger picture, discussing how we should fit our easy running into our training weeks and practical tips on how to let go of our egos.

Threshold training has come to prominence in recent years, primarily through the success of the Ingebrigtsens. In this episode, I discuss what threshold training actually entails, why it might be a useful intensity to train at, and what are the limitations with threshold training. A lot of the dicussion is centred around a recent review that discusses why "The Norwegian Model" of training may be the next step in the evolution of training practices.

Yes, we are finally back! In this episode, we delve into the physiological model of endurance running performance. We discuss the determinants of VO2max, metabolic thresholds and running economy. We cover additional parameters that are important in the middle-distance events and distances beyond the marathon. Lastly, we discuss the relative importance of the physiological parameters across the different events and how we might determine what is limiting our performance.

In this second episode of The Physiology of Endurance Running Podcast, we explore all aspects of the 2nd threshold. We cover:

• What is the 2nd threshold and why is it important for performance
• What do we know about the determinants of the 2nd threshold
• Do we know how best to train it?
• How can we use the critical speed model to calculate our 2nd threshold outside of a lab and without lactate measurements
• How can we apply the critical speed model to our own training

Critical Speed Calculator

You can access the calculator via this link. You will need to download the Excel file in order to edit the document. Let me know if it doesn't work!

In this first episode of The Physiology of Endurance Running Podcast, we explore what the research has to say on how best to fuel your marathon. We cover:

• The pros and cons of fat and carbohydrates as fuel sources
• Why taking on carbohydrates aids performance
• How much carbohydrate should we take on during a marathon
• How to choose which fuel type to take on
• How to plan your own nutrition strategy for training and racing

Post-production corrections
At 34' I say that Maurten gels contain 40g of carbohydrate. They actually contain 25g while SIS Beta Fuel gels that I also refer to contain 40g

In today's in-person episode, Dan and Owain break down the physiological components of marathon running.

There's more to the marathon (and other distances) than just having a big VO2max! Thresholds, economy, and durability all interact with each other, and as you'll hear, there's more than one way to run a marathon from a physiological perspective.
