Race Across the World star Alfie gets emotional remembering late mum

In truly emotional scenes, the pair see hundreds of lanterns floating on a canal in the city and Alfie opens up about how the lantern symbol reminds him of his mother, who was diagnosed with breast cancer and died when he was five years old.

"In Hoi An there are a lot of lanterns around which is an item which is very close to my heart," he says. "I was just thinking about maybe taking a minute to myself."

The locals of Hoi An consider their light to be a symbol of life, and release them onto the river to pay respects to their ancestors.

Alfie continued: "When my mum passed away, we set one off every year with a message attached. So, to be able to reignite that would be incredible.

"This is kind of the first opportunity on the race that I have had to think about my mum, and I'm just inundated with emotion that I have just not felt, genuinely, since I was a little kid. I just want that sensation of being able to see her again."

Tomorrow's episode will test the teams like never before as they have to make it to Phnom Penh, and the team who arrive last will be eliminated from the race.

There are two options the teams can choose from: Stick to the popular route along the Vietnam coast and follow the Mekong River into Cambodia. Or, travelling across country and aim to get to the Cambodian border as soon as possible.

Viewers will have to tune into tomorrow's episode to see how the teams manage.

Race Across the World season 4 continues on Wednesday 25th April at 9pm on BBC One and iPlayer.
