ISKA Muay Thai World Champion Charlie Guest did not grow up dreaming of becoming a fighter. He grew up just trying to get things right. The dream came later, and when it did, he chased it harder than anyone around him thought possible.
The 30-year-old makes his hotly anticipated promotional debut in a featherweight Muay Thai clash against Sam Fitzgerald at ONE Fight Night 44: Jarvis vs. Rungrawee II on Prime Video, live in U.S. primetime on Friday, June 26, from Bangkok’s iconic Lumpinee Stadium.
Before he steps through the ropes, here is how the Englishman overcame every hurdle life threw at him to find himself on the global stage of ONE Championship.
The Making Of A Fighter
Guest grew up in Andover, England, raised by his grandparents from the age of 5 after his parents’ drug addictions made home life untenable.
His father passed away as a result of those habits. For a child in those circumstances, the fork in the road arrives early. He saw with complete clarity which direction he refused to go.
He reflected:
“My parents had drug habits, and I just didn’t want to have anything to do with them. So, it just put me on the straight, and I never wanted to turn out like them.
“It wasn’t really a pleasant scene. But as they say, things happen for a reason.”
His grandfather had served in the British Army for 22 years. His grandmother, meanwhile, worked as a nurse. They were his first real-life superheroes, and Guest absorbed all of it growing up under their roof.
From his granddad’s discipline and work ethic to his grandmother’s kindness, these values were the foundation upon which everything that followed was built.
The Brit continued:
“My granddad was just always making sure I was on the right path. My nan took care of everything that I needed from day to day. They are the biggest inspirations in my life.
“I wouldn’t be the man I am today without them taking me in. I couldn’t even comprehend where I’d be without them, really. So I’m just super grateful for them.”
The Accidental Discovery That Became Everything
By his mid-teens, Guest had moved into foster care in Bournemouth. The chapter was difficult, but it delivered something that would change the course of his life entirely.
The young Englishman did not set out to find Muay Thai. He walked into an MMA gym in Bournemouth one evening – and the session that night happened to be the sport that he calls his bread and butter today.
Guest said:
“I just ended up doing the Thai boxing class, and I just absolutely fell in love with everything about it.
“The noises, the pads, the people. I just fell in love with it. So I didn’t even bother going back to MMA. I just went to Muay Thai classes every single night.”
The hobby, eventually, became a career. Two years of training came and went. The young teen grew confident in his arsenal, and a couple of amateur fights followed suit.
Something about the sport had taken root in him at a level far deeper than enjoyment. At 16, equipped with savings from his time in foster care and a certainty that most adults twice his age would struggle to match, Guest booked a flight to Thailand.
It was the first time he had ever been on a plane. His destination was Sitmonchai Gym. Apart from the bag of clothes and a mobile phone, he brought the belief and confidence that this was a step in the right direction.
However, his first training session hit him like a freight train:
“The main shock was how hard the training was compared to back home. I was only a boy as well. How much they ran, all the pad work morning and evening — it was crazy.
“But the gym I went to, luckily, [took good care] of me. They were like a big community family. So for my first time, it was brilliant. And I just had that belief that I knew I’d make it one day.”
Building A World-Class Resume
Guest returned to England, earned a construction diploma and a Level 3 personal training qualification, and spent years working as a heavy goods vehicle driver, all of which kept the bills paid.
Through it all, the grind never stopped. He upgraded his Muay Thai arsenal to a whole new level – the sharpness of his clinch work, the patience of his timing, and the finishing instinct that has produced 14 knockouts across his career.
He built a resume that commanded attention within the local British and European scene. Winning the ISKA World Title in October last year crystallized everything he had been working toward:
“That was the moment I knew I was at the top of my game. That was when that flick switched, and I knew I could go on and chase bigger dreams.”
The win did not change Guest’s approach. Having that belt wrapped around his waist was only one step in his road to greatness.
For years, he watched the likes of reigning ONE Bantamweight Kickboxing World Champion Jonathan “The General” Haggerty and English martial arts icon Liam “Hitman” Harrison ply their trade in the world’s largest martial arts organization.
That was where he, too, one day dreamed of displaying his skills:
“The ultimate goal was to always just keep grinding until I got into ONE Championship – to the big stage. That was always the goal.”
Ready For The World’s Biggest Stage
Guest was at home when he received news that ONE Championship came calling. He got off the phone with his manager and walked straight to his wife, whom he married in November 2021.
She could not believe it either, and for a woman who had been beside him through every shift and every long road back from a difficult session, that reaction said everything.
The Impact MMA and Tiger Muay Thai affiliate shared:
“It was like a dream come true, you know? I couldn’t explain the feeling. My wife and I were just absolutely over the moon. It’s something I’ve worked towards my whole life.
“It’s been a long journey, so I’m happy it’s actually here now. I’ve been manifesting this for a very long time, so it just all feels natural and I’m super excited for the experience.”
Fourteen years after a 16-year-old from Andover boarded his first-ever flight to Thailand alone – no map, no guide, just belief – Guest steps into Bangkok’s iconic Lumpinee Stadium with the world watching. The dream is finally here.
His opponent at ONE Fight Night 44, Sam Fitzgerald, stepped in on short notice after Bampara Kouyate was ruled out through injury. The change has not disrupted a single element of Guest’s preparation or his mindset, though.
If anything, it has him fired up even more, and he does not plan to do any overtime when he steps through the ropes in Lumpinee Stadium on June 26.
Guest concluded:
“I just wanna go out there and show what I can do and make a statement. I’m here to fight anyone and everyone. The game plan remains the same.
“I personally think the knockout will arrive with an elbow. Most of my knockouts come from elbows, so I’ll be looking to unleash them come fight night.”
