    From Lab to Start Line: Building a 2:09 Marathon Blueprint

    In February 2026, I ran 2:11:49 at the Seville Marathon. Now, 22 weeks out from Seville 2027, I'm going after a lifetime ambition: breaking 2:10 for the first time. The starting point isn't ideal. A new addition to the family meant a light summer of training, so before writing a single session, we went to the Sport Physiology Hub at Cardiff Met to find out exactly where my physiology stands right now. In this episode, we go through that lab data in detail and show how it becomes the blueprint for the build ahead. We cover: What the test results reveal about my current fitness and what they mean for the marathonHow I use the data to set and tightly control time spent in each intensity domainWhy I'm using a block periodisation approach to target specific physiological characteristics one at a timeHow the plan comes together over the next 22 weeks This is a real-world case study in applying a science-based, evidence-led approach to marathon training, from the lab to the start line. Whether you're chasing a PB of your own or just want to understand how physiology translates into a training plan, this one is for you.

    A deep dive into New Zealand blackcurrants & the heat

    Dan & Owain take a deep dive into New Zealand blackcurrants and anthocyanins, specifically looking at their possible benefit in the heat. They also critically discuss applying research in the supplement space, and the evidence that exists for blackcurrants and other supplements on the market.

    Your guide to getting lab testing

    In the last few years, lab testing has exploded as an industry - expanding beyond a few universities offering tests in their laboratory. Unfortunately not all tests are equal, and having seen more bad tests, Dan & Owain talk through what you should be looking for from a lab test. Send us in your tests and we might do an episode talking through some of the bad ones soon!
