Performance scientist Dr Peter Tierney joins Dr Sophie Bostock to explore what elite sport can teach us about sleep, recovery, and sustainable performance. Having worked across professional rugby, football and wearable technology innovation, Peter brings a rare perspective on how recovery habits translate from elite athletes to everyday life.

In this episode, Peter shares what separates the highest performers from the rest, how attitudes toward sleep have evolved in elite sport, and why recovery should be viewed as a system rather than a quick fix. Together, they unpack the role of wearable technology, the impact of late-night training and travel on sleep, and the practical habits that can help anyone improve recovery in an always-on world.

Blending science, coaching and real-world experience, Peter offers evidence-based insights and practical strategies for building healthier, more sustainable sleep and recovery habits, whether you’re training for a marathon, or simply trying to perform better in daily life.

Record-breaking adventurer, explorer and keynote speaker Darren Edwards joins Dr. Sophie Bostock to uncover an often overlooked part of the journey: sleep. After a climbing accident left him paralysed from the chest down, Darren transformed adversity into a platform for pioneering expeditions, leadership and resilience.

In this episode, Darren discusses how major physical trauma, intense rehabilitation, and life-on-the-edge challenges have shaped his relationship with rest. He reveals how recovery, expedition planning, mental strength and discipline all intersect with sleep, from hospital nights to sleep-deprived gear shifts in extreme environments and back to everyday rest at home.

He shares raw reflections and practical strategies for how to reclaim rest when your body and mind refuse to switch off, how sleep becomes a vital tool in rebuilding a life, and how resilience isn’t just about doing more, it’s about recovering better.
