Race Across The World winners crowned

Warning: This article reveals the winners of Race Across the World.

The winning duo will share a cash prize of £20,000.

Teams had to pass seven checkpoints in China, Nepal and India on their route to the finish line.

As usual, all pairs were banned from travelling by air, and instead were given a budget of £1,140 per person for the journey - the cost of a one-way plane ticket.

They could not use their smartphones or bank cards while seeking out their own transport, food and accommodation.

According to TV ratings body Barb, just under six million viewers per episode have been tuning in or catching up on iPlayer within a seven day period.

This means the series was the most watched programme in the UK across all channels and streaming platforms during each week it aired, with the exception of the week the Eurovision Song Contest was broadcast.

The mother-and-son duo thought the show would be a unique opportunity to create treasured memories.

Both are from Hargrave near Bury St Edmunds in Suffolk, but only Tom, 21, had travelling experience as he had spent about 10 months in South America and Europe.

During the show, Caroline, 60, opened up about how she felt she had, in recent years, lost her identity outside being a mother and a wife.

Meanwhile, her son found new confidence when he told strangers about his cerebral palsy for the first time.

The duo are now planning to head to Kazakhstan for a month of backpacking.

"No idea why," said Tom. "No idea what Kazakhstan has to offer, but we loved when we did Race that we had no idea where we were going."

Both felt their experience on the show had brought them closer together, but for Caroline it also gave her a new confidence.

She explained: "Its made me feel stronger inside, as though I can now cope with more.

"I'm not as frightened of being lonely and I feel I can reach out and speak to people, whereas before I would hide behind some sort of mask that we all expect of somebody my age I think."
