Who am i?
I’m Paul. I’m a qualified Sports and Performance Nutritionist, Exercise Physiologist, Academic, and PhD Researcher in Ultra-Endurance Metabolism, Physiology and Performance. I’ve been trail and ultra running for over two decades. Recently (August 2026), I completed my 94th ultramarathon at UTMB OCC. I’ve competed in races such as UTMB, PTL, Ironman, 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.
