Roman Kemp‘s sister Harleymoon has revealed the secret three words he said to her that secured their Celebrity Race Across the World 2025 win.

The sibling duo, whose parents are 80s singers Martin and Shirlie Kemp, won the BBC series last night with just minutes to spare.

Roman and Harleymoon endured a last-minute scrabble up rocky hills to secure their victory, with Molly Rainford and Tyler West hot on their heels.

The pair then collapsed into each other’s arms as they opened the guest book to discover they had won.

Harleymoon has now revealed the secrets behind that final scene – including how long it really took to scale the cliffs.

The country music singer has also let slip what three words Roman had said to her to her that got them to first place.

Speaking after their win, Harleymoon said of those final moments: “Roman was like a daddy long legs, with his skinny long limbs, floating through the wind like a dandelion. I was feeling so sick because I really was struggling to want to keep running.

“But I could hear Molly and Tyler’s footsteps on the gravel behind me, and that was the only thing. And I remember Roman saying, ‘Don’t look behind you’. He said, ‘When they chase you, don’t look behind you. Just keep going’.

“In my mind, I was like, ‘Don’t turn around. Don’t turn around’.”

Recalling the moment she saw Roman touching the book ahead of her, Harleymoon adds: “I looked up and I saw Roman had touched the book.

“My legs were like jelly, I couldn’t even run, the adrenaline, the nerves, the overwhelming sense of what has just happened.

“It’s the fastest I’ve ever run in my life. I’ve never run before, let alone been chased by the fittest couple in the world!”

Celebrity Race Across the World viewers were gripped on Thursday night as the series drew to a close.

The teams’ last leg was from Medellin in Columbia to Uribia in the Península de La Guajira. Molly and Tyler had a head start, having finished the fifth leg in first place.

Roman and Harleymoon followed shortly after, with Anita Rani and her dad Bal then setting off. But there was a shock in store for viewers.

Derry Girls actor Dylan Llewellyn and his mum Jackie made the decision to quit the race before setting off. The mother and son team had just £14 left in their budget and decided to end the race ‘on their terms’.

In the end, Roman and Harleymoon got to the final checkpoint first. Molly and Tyler finished in second place, losing out by just minutes. Anita and Bal arrived in third place six hours later.

The most tense moment of the entire finale episode was Roman and Harleymoon’s last dash up the cliffs with Molly and Tyler following right behind.

But Harleymoon has now also revealed just how gruelling – and long – that scene really was.

Once the final had aired, Harleymoon took to Instagram and congratulated Molly and Tyler for such a close finish. But she also admitted the run on foot was actually TWO HOURS long!

Harleymoon said: “We made it. Against all odds. Tonight we just hugged our family who were proud of us for even taking part.

“@mollyrainford and @tylerwest were literally inches behind and equal winners in our eyes. You guys saw 5 minutes but that run route was nearly 2 hours long of chasing…

“Could not have run like that against any other team and we laughed and hugged together after.”

Impressive or what?!
