The Physiology of Endurance Running Podcast

Dan Nash and Owain Zerilli 106 Episodes Jul 1, 2026

This podcast is all about getting sport science research out into the public domain. We cover what we do and don't know regarding all topics related to endurance running performance and, more importantly, how can we use this information to make ourselves healthier and faster runners! Your hosts are Dr Dan Osborn-Nash, 2:12 marathon runner and sport physiologist for Welsh Athletics and Welsh Triathlon, and Owain Zerilli, MSc student exploring the effects of heat on EPO release and 2:38 marathon runner.

Taurine - the supplement to beat the heat? Jul 1, 2026 00:55:23 Dan & Owain talk through Taurine - well known to anyone that drinks Red Bull or Monster, but a supplement that may improve your performance in the heat!Is there a good evidence base? Or are things a bit unknown?Have you tried Taurine yourself?Taurine Supplementation and Human Heat Tolerance: Mechanisms, Evidence, and Integration with Heat Acclimation, Cooling, and HydrationAcute taurine supple
Can AI replace your running coach? Jun 24, 2026 01:13:03 Following the launch of a Claude and Strava integration, Dan & Owain put their livelihoods on the line and test the protocol! A range of questions was put to Claude to interrogate their data, with varying results!Check back in in 12-months and we will see if AI has made us redundant!

All about HRV - with Marco Altini Jun 17, 2026 01:15:52 Dan & Owain are joined by a leading voice on HRV, Marco Altini. Marco has worked on HRV, both the physiology behind the measure and applying the data in day to day life for many years. He talks to us about what HRV is, how to properly measure and apply HRV data, and the state of wearable tech in 2026. Marco's book can be found here!Marco's SubstackSoar Solstice⁠⁠The Physiology of Endur
Will tilting your bed make you run faster? (and how to critically analyse a paper) Jun 10, 2026 01:03:14 Dan & Owain talk through a recent paper that's hit the mainstream - suggesting that tilting your bed may increase haemoglobin mass.It's a catchy premise, but they talk through how to actually read and apply a study like this into your training and life!The paper!Soar Solstice⁠The Physiology of Endurance Running podcast is proudly sponsored by SOAR.

Critical Speed, critical for your training? May 20, 2026 00:59:42 Dan & Owain are back to discuss the Critical Speed model. The model is often used in sport science research, as another method of quantifying the steady state and non-steady state boundary, but utilising performance trials or race data rather than metabolic measurements.More to come on this topic in the next few months!A very good paper about Critical Speed⁠Check out our Soar Giveaway here!⁠⁠⁠
Your guide to get fast this summer! May 13, 2026 01:10:39 Dan & Owain are back with a discussion about how to inject some speed into your marathon legs over the summer!Lots of runners spend the summer trying to run a fast 5k off the back of a spring marathon - and Dan & Owain discuss an evidence-lead approach to this, with a few scenarios in mind!Hopefully this offers some good insight and ideas for your summer, if you're targeting shorter events

Training Block Breakdowns Apr 29, 2026 01:37:51 Following a big spring of racing, Dan, Jen & Owain are back to break down their training, and how they apply some of the podcast topics to their own running!Dan talks us through training and racing 3 marathons in 30 weeks. Jen discusses what stayed the same, and what changed between Valencia and Rotterdam. Owain breaks down the change from flat road racing to technical trails!⁠Check out our So
So, you've just run a marathon... Apr 22, 2026 01:12:10 Dan & Owain round off the marathon series, with a discussion about the stress and strain your body has just been put through over the course of 26.2 miles!There's a lot to recover from post-marathon, some of which is obvious, and some of which is a lot more nuanced and less understood. They then talk about their approaches to returning to run after a marathon, or other big races!The Physiology
From Taper to Marathon Start Line: Mastering the Last 48 Hours Apr 15, 2026 01:14:20 Dan & Owain talk through the final 48 hours before a marathon. There's lots of ways to jeopardise your race, and undo the training you've done in the weeks before. A real mix of science and practical application in this episode as they talk through lived experiences and research based approaches to the days before a marathon!The Physiology of Endurance Running podcast is proudly sponsored by S
