Kurtis Campbell was seven years old when his parents decided enough was enough.
Primary school in Liverpool had turned into a daily ordeal. Bullies had picked him out, and the damage was obvious to anyone paying attention. Jay and Michelle, watching their son shrink into himself, made a choice that would change his life: they walked him into a Muay Thai gym.
It was meant to be self-defence. A bit of confidence before secondary school. Nothing more.
It became everything.
"From there, I've never looked back," Campbell told BBC Sport. "I've been in love with the sport ever since."
Seventeen years on, that quiet, soft kid is a 24-year-old UFC lightweight preparing for his second fight in the promotion, facing American Trevor Peek at UFC Paris on Saturday. The boy who hated confrontation now makes a living from it, chasing a world title with the same single-mindedness that once drove him to lace up gloves after school instead of kicking a ball in the park.
And at the heart of it all are the two people who first opened the gym door.
"I'm not going to stop until my mum and dad are on a beach somewhere, sipping cocktails and doing nothing else for the rest of their lives," Campbell said. "They can enjoy it, knowing that they've created this monster. That's my plan."
From bullied schoolboy to ring obsession
Campbell never set out to be a fighter. He didn’t even like fighting.
"I was quite a soft kid, in the sense that I didn't really like the violence or the fighting," he said. The ring, though, offered something different. Structure. Focus. A place where the noise of school melted away.
He started entering amateur Muay Thai competitions. Small shows at first, then bigger ones. Each bout pulled him deeper into a world that felt more like home than the classroom ever did.
"I felt like when I did fight, and when I really did go into it, everything changed and I never looked back."
By 15, he had his first international Muay Thai title. The medals and belts were proof of what his parents had already seen: this wasn’t a phase. With their blessing, the sport moved from hobby to calling.
Teachers, though, saw a different story. Campbell was never top of the class. Far from it.
"I was never the cleverest kid. I was always in the bottom sets at school, so I wasn't really focused," he admitted. "All of the teachers told me, 'you need to do something else. You have to have a plan B.'
He heard them. He just didn’t agree.
While classmates juggled homework and part-time jobs, Campbell built his own routine. He would run almost five miles to and from school, folding roadwork into the school day, every pavement a training ground. On one occasion, studying for his GCSEs took a back seat as he skipped school altogether to attend a coaching seminar in Liverpool led by John Kavanagh, the man behind former two-weight UFC champion Conor McGregor.
To his teachers, it might have looked reckless. To Campbell, it was non-negotiable.
Dodging the pitch, chasing the fight
After finishing his GCSEs at 16, he moved into college and enrolled on a course that blended academic work in sport with football. On paper, it was a balanced programme. Books and boots. Classrooms and pitches.
Reality looked very different.
Campbell struck a quiet deal with the course leaders: he would turn up for the classroom work, then peel away when it was time to play football. While his peers ran drills and practiced set-pieces, he headed back into the world of combat sports.
"I was always avoiding anything just for fighting," he said. It wasn’t that he hated sport. He just knew which one he belonged to.
"I really didn't like school. It wasn't me. But I made a good few mates there, so you've got to take the pros with the cons."
The pattern never changed. When given a choice between the conventional path and the gym, Campbell chose the gym. When told to find a plan B, he doubled down on plan A.
Now, as he walks into UFC Paris for his second outing in the promotion, the stakes are higher, the lights brighter, the opponents far more dangerous than the bullies who once waited at the school gates. The aim, though, is the same as it was when he first stepped onto the mats in Liverpool: protect himself, prove himself, and make sure his parents never have to worry again.
