Endurance Athlete and Performance Coach Daryl Green Launches Self-Designed 1000km Triathlon – “Tri-M”
Daryl Green, British Army veteran, high-performance coach, and extreme endurance athlete, is set to embark on a mission that redefines what the human body and mind can endure: Tri-M, a self-devised 1000km triathlon built around grit, purpose, and self-leadership.
Tri-M is no conventional race. Designed entirely by himself, the challenge spans 1000km of swimming, cycling, and running across remote and demanding terrain spanning England. It is a self-imposed, self-created test of physical capability and mental resilience, rooted in his philosophy that real performance is forged through challenge and discomfort.
With a track record that includes CrossFit competitions across Europe, multiple ultra-marathons, a 24-hour rowing challenge, a full Ironman, and a 5-day run across the Arctic Circle, He is no stranger to extreme feats. But as he explains, Tri-M is different:
“Tri-M is about meeting the version of yourself that shows up when everything easy is gone. The purpose is to drive and inspire mental wellbeing and purposful change”
As the founder of DG Performance Coaching, he trains individuals and teams in physical resilience, mental flexibility, and values-driven living. His coaching system, and The Adventure Advantage, blends hard physical effort with the emotional intelligence and strategic thinking needed to excel under pressure. Tri-M is the living embodiment of this approach.
Tri-M is not only his personal challenge it is one created to raise money for Rock 2 Recovery and The You Trust
