Teenage running sensation Michael Clark is not short on belief.
“I really think I can have a career in this sport,” he says. “I do feel like I’ll be able to hit the biggest stage – Diamond League level, maybe Commonwealths or Worlds in the next few years. I genuinely believe I can run among the best.”
It’s a bold ambition, but one increasingly backed up by results.
Earlier this year, Clark pulled on a British vest at the 2026 World Athletics Cross Country Championships in Tallahassee, Florida – and finished as first scorer for Great Britain in the under-20 race.
“Running in a British vest and coming as high up as I did – that meant a lot to me,” he says. “Being the best British scorer, that’s another reason why I love this sport. It shows the progress I’ve made.”
That sense of momentum had already been building through a standout cross-country season.
Clark, who in sponsored by On, stormed to victory in the under-20 race at the Liverpool Cross Challenge, one of his favourite performances to date, before heading to Belgium where he claimed another international win.

He took the junior men’s title at the 2026 Hannut CrossCup on January 25, leading from the early stages of the race. England teammate Jack Marwood finished second, with Belgium’s Axl Hermans and Romain Palm also featuring prominently at the front.
Clark finished fifth in the U20 race at the London Cross Challenge at Parliament Hill last weekend. He’s 17.
But it was his European Cross Country Championships race that truly captured attention.
Clipped in the opening stages, Clark lost a shoe within the first 100 metres. He ran the remainder of the 5km course with one foot bare, skin scraping against gravel, yet still finished strongly enough to help Great Britain secure team silver.
“I don’t even know how I lost it – one moment it was there, next it wasn’t,” he recalls.
Dropping out was never considered.
“I’d dropped out of a race the year before with breathing issues and it really affected my confidence for a month. After that I promised myself I’d never quit again, no matter what.
“I had skin missing from the bottom of my foot and I was stepping on gravel – but I knew I was the third British runner, so that pushed me even more. I just had to finish.”
That resilience has been forged over years – and across continents.
Clark grew up in Hong Kong, where running is far from the dominant endurance sport.
“Running isn’t that big there – triathlon is massive,” he explains. “My mum entered me into a fun family 5K race when I was about eight. It went over a big mountain, nothing fast – but I ended up winning by over a minute and a half.
“I still remember it. I loved it straight away.”
He spent four years in a triathlon squad, but running was always his strongest discipline. When his family returned to England, he made the decision to focus solely on athletics.
His first parkrun came at just 14 years old – with no structured training – and he clocked 19 minutes 30 seconds.
Between then and Norfolk Schools Cross Country, Clark was simply running once a day, with no intervals and little guidance. His longest run before the county championships was around 8km.
Yet he still won Norfolk Schools by over 90 seconds.
“That’s when I realised something serious was going on,” he says. “I knew I had loads of potential to unlock.”
Soon after, he joined City of Norwich Athletics Club, a move he credits as pivotal.
“Without City of Norwich, I wouldn’t be anywhere close to where I am now,” Clark says. “Before that I was training on my own. You can only develop so far without people pushing you.”
Under coach Jane Clarke, Clark became part of a tight-knit training group including Zachary Dunn, Will Percival and Harry Smith – with regular Tuesday sessions turning into competitive battles.
“When I first joined, every session was basically a race,” he laughs. “That pushed us all on so quickly.”
Now, Clark mainly trains alongside Will Percival, who continues to challenge him in speed sessions.
Jane Clarke’s influence, however, runs deeper than training schedules.
“She’s probably the nicest and most supportive person I know,” Clark says. “Apart from my parents and my girlfriend, no one backs me like she does.
“She puts so much time and effort into me. Sometimes she gives me a pace and I end up running 20 seconds quicker – but she’s always patient. That support makes such a difference.”
Progress followed fast.
Clark sliced huge chunks off his personal bests, moving from a 19-minute 5K runner to 15:40 in just six months, before later producing his standout 14:08 performance at Battersea Park – a moment he describes as when people began to truly take notice.
“I felt the shape coming,” he says. “But actually going out and doing it is different. That’s when people realised I was properly a threat.”
Despite the rapid rise, Clark remains grounded away from competition. After each cross-country season he takes a full two weeks off, deliberately stepping away mentally as well as physically.
“I try not to think about running,” he says. “I just hang out with friends, spend time with my girlfriend, go hiking or to the beach if I’m on holiday – anything that clears my mind.”
Looking ahead, Clark already has one eye on the United States, where he hopes to secure a university scholarship as part of his long-term development.
“I’m pretty set on going to America,” he says. “That’s where I want to progress.”
When asked about role models, there’s only one name: Norwegian superstar Jakob Ingebrigtsen.
“He’s my only real role model,” Clark says. “He’s right on the edge between confidence and cockiness – but the difference is he backs it up. The way he runs, the way he races – I’d argue he’s the best of all time.”
For now, Michael Clark remains a teenager from Norwich with big dreams and blistering potential.
But with international vests already on his back – and world-class ambition in his voice – it may not be long before those dreams place him on the same start lines as his hero.
Perhaps, one day in the not too distant future, he might be tucked in behind him, ready to strike.
