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. This year (2026), I completed my 90th ultramarathon. I’ve competed in races such as UTMB, road marathons, fell and trail races, 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 included Ultra Trail Snowdonia, Laveredo, and Eiger Ultra Trail. In 2026 I have a number of races planned, including the UTMB OCC in August.
