Who am i?


I’m Paul. I’m a qualified Sports and Performance Nutritionist, Exercise Physiologist, Academic, and PhD Researcher in Trail and Ultra Endurance Physiology and Metabolism. I’ve been trail running for over two decades, competing in my first ultramarathon 20 years ago. In the years since I’ve completed 89 ultras, and over 150 trail/fell races, road marathons, cycling, ski, and Ironman triathlon events. I’ve competed in races such as UTMB, long-distance challenges such as the Bob Graham Round, bikepacking races and alpine fastpacking expeditions.

This is me travelling hut-to-hut on the Dolomites Alta Via 2 route.

In 2025 my race calendar includes Ultra Trail Snowdonia, Laveredo, and Eiger Ultra Trail.
