#404 Fuel What Matters: Performance, Recovery & Supplementation with Dan Peskett, Martin Boyce & Xendurance

Endurance sports have never been bigger—running, triathlon, Hyrox, cycling, and now the rise of firefighter challenge events are pulling more and more people into the world of testing limits. At the heart of these challenges lies a key performance barrier: lactate threshold and that familiar muscle burn that can shut you down when intensity peaks. It’s about finding ways to go further without hitting the wall.

In this episode, I’m joined by Dan Peskett from Xendurance and my good friend Martin Boyce from the UK Fire and Rescue Service to explore how athletes and tactical professionals can push harder for longer. We dive into lactate and muscle acidosis, creatine’s role in both strength and cognitive performance, fuelling strategies for sustained energy, and why recovery and immune support are essential when training load is high.

This conversation is all about connecting endurance science to real-world performance—whether you’re racing, taking on a firefighter challenge, training for a marathon, or responding to the unexpected, it’s about fueling what matters and staying sharp for the long run.
