They travelled 15,000km in 50 days, completing a thrilling walk to the finish line on Wednesday.
However, fans of Race Across The World may not have to wait long for the next instalment, as the BBC has teased an upcoming celebrity series.
As the final episode drew to a close, viewers were able to see a preview of the next race, this time featuring a celebrity pair.
In the footage, the next group of racers can be seen taking on the mountainous terrain, and fans are convinced they’ve caught one of their stars.
“OMG is that @scott_mills’ voice in the trailer for Celebrity Race Across the World?” someone commented on X (formerly Twitter). “Love him on Radio 2 and he was great on Radio 1 too.”
Another person wrote about the new series: “Can’t wait for Celebrity Race Across the World, come on now.”
“*Celebrity Race Across the World will be broadcast shortly on BBC1. UK: *Cheers.”;
“Next up: Celebrity Race Across the World”; “This concludes the fourth series of Race Across the World. Well done Owen and Alfie. See you in the Autumn for series two of the celebrity edition of #RaceAcrossTheWorld”;
“Massive congratulations to Alfie and Owen on winning the round the world race. @studiolambert has produced another fantastic series, looking forward to the celebrity version.”
“And a celebrity race across the world. So yeah, everything is perfect right now.”
“From a couples perspective, it’s the best race series in the world so far. I’m happy they won too. I’m looking forward to the next Celebrity Race!”
In the current series, a 15,000km race across East Asia came to a tense conclusion with two pairs of riders battling for the lead nearing the finish line.
After arriving at the penultimate checkpoint in Jakarta just 12 minutes apart, Alfie and Owen, along with Isabelle and Eugenie, were eager to take the lead on the final leg.
The two pairs met multiple times on the journey from Jakarta to Lombok, after which they both had to cross by boat at exactly the same time to a small island offshore.
After finding a speedboat, the pair set off quickly across the ocean, preparing to walk the rest of the way.
The race finished in a dramatic sprint along the beach, with best friends Alfie and Owen arriving at the check-in book in first place and taking home the £20,000 prize money.
Close behind their school friends were mother-daughter duo Eugenie and Isabelle, who finished just eight minutes behind.
In third place were beloved siblings Betty and her sister James, who overcame budget dwindling and trouble to arrive a day late.
Husband and wife Steven and Viv came in fourth place with a whopping £180 left over from their budget.
In a dramatic final scene, Alfie and Owen sprint across a beach surrounded by Indonesia’s sparkling tropical waters to reach the book and discover they’ve won the race.
“We did it,” they shouted and hugged each other.
Owen proudly stated, “We came, we saw, and we made it.”
“This is the best moment of our lives,” Alfie added. “Hands down. It’s unbelievable.”
Eugénie and Isabelle opened the book and saw that they were a few minutes late to the boy.
Eugenie said: “We did it, we’re in a good position and I’ve always said that if I was going to lose to anyone I wanted to lose to Alfie and Owen.”
The next day, after 24 hours and 34 minutes, Betty and James reached the finish line, followed by Steven and Viv six hours later.
