Daryl Green is no stranger to pushing limits. A veteran soldier and firefighter, he’s built a life around testing both body and mind. But his latest feat, a 1,000km Tri-M challenge, wasn’t just about endurance. It was about transformation, purpose, and paying it forward. His Tri-M, the M standing for 1,000 in Roman numerals, was to raise money for his two chosen charities. One that helps veterans, and our charity, who helped Daryl with counselling.
A lot of kilometres have been travelled since we first sat down with Daryl in May, 2025. Not only did he complete the gruelling challenge, but he’s also made a documentary of his accomplishment! We asked him a few more questions after his challenge to find out exactly why he wanted to do it, and whether he’d change how he did it.
Why did you want to do the Tri-M challenge?
“I chose the challenge to see, feel, and push myself” Daryl explains. “To identify new limits, learn who I am and what I can do, and enjoy the adventure.” But it wasn’t just personal. Daryl’s mission was to inspire others to keep moving forward, especially those facing hardship. “If I could influence even one person to not give up, to change their trajectory, it would be worth it.” This fits with Daryl’s motivational, coaching lifestyle.
Daryl’s first challenge was to swim to the Isle of Wight and back, which is 15kms. Unfortunately, the weather made this dangerous. However, at the last minute, he was given permission to use a 1km ‘swimming pool’ at the Royal Navy Marine Diving School in Portsmouth.
The Swim: A brutal start
Though the swim was the shortest leg, it packed a punch. “It was three times my longest ever swim,” Daryl says. “I underestimated how hard it would be to eat and hydrate during it.” The result? Intense fatigue and uncontrollable shivering for an hour post-finish. “I felt sick. It was brutal.”
The Bike: doubt and determination
As the cycling leg began, excitement gave way to uncertainty. “I did question if I’d bitten off more than I could chew,” he admits. But doubt didn’t slow him down for long. In fact, he made it to Robin Hood’s Bay in excellent time. Every kilometre was a lesson in resilience, though.
Reaching Robin Hood’s Bay marked the final stretch. “This is a long way,” Daryl laughed. “My butt was happy to get off the saddle—little did it know it wouldn’t be the last.” The exhaustion was real.
The Run: To St Bees
Daryl’s last leg was heading west, to St Bees Bay in Cumbria. He’d hurt his ankle riding, and so had to alternate between running and cycling so he didn’t damage himself further. Encouraged by his team, and his own internal motivation, he made it to the finish line.
When asked what he’d have done differently, he was adamant. “Nothing,” Daryl says firmly. “This was about adventure and dealing with what arises. Life is fragile. One small action can change so much. Even if I changed something, it might not have worked out.”
Next steps
Daryl’s mind is always on the next challenge—but not just for himself. “My biggest challenge is making the most impact on people’s lives. Sharing my experiences to help others.”
On 23rd September, he’ll climb Mont Blanc, Europe’s second-highest peak at 4,805m. Another mountain, another mission.
