Double UTMB 2025 Winning Nutritionist and Performance Scientist.
I advise and consult on performance science, nutrition, physiology, and athlete testing. I specialise in ultra-endurance sports (running, triathlon, cycling), working with individual elite and sub-elite athletes, teams, groups and organisations. I currently work with the Salomon International Team, and MNSTRY nutrition, along with a number of athletes.
My PhD research investigates performance and fuelling during ultra-endurance exercise.
I can provide consultancy services, such as 1:1 athlete support, team strategy, workshops, talks and education for individual athletes or teams.

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.
