I’m an author, endurance coach, high-performance consultant, technologist, and entrepreneur. As Co-founder and CEO of HIIT Science and at Athletica, I combine science, innovation, and years of elite-level experience—including leading physiology for New Zealand’s Olympic athletes—to help individuals and teams unlock their full potential. With over 150 scientific publications, 17 Ironman finishes, and a passion for coaching and experimentation (including the perfect steak), my mission is simple: to help you train smarter, perform better, and thrive.
