手足之爭與冒險：沒有手機，橫跨大陸的競速之旅！

Katie and Harrison Devine are siblings from Manchester who decided to take part in the BBC show Race Across the World. Katie is 21 and works as an account manager, while Harrison is 24 and works as a finance assistant. They joined the show because they wanted to have an adventure together. On the show, they are seen wearing backpacks and smiling, ready to take on the challenge. Katie has long blonde hair and usually wears a white t-shirt, while Harrison has short ginger hair and wears a blue t-shirt.

Race Across the World is a show where teams of two travel across Europe and Asia without using flights or phones, and with only a small amount of money. This season, the teams started in Palermo, Sicily, and are racing all the way to Hatgal, a remote village in northern Mongolia. The journey is more than 12,000 kilometers long, and the winning team will get a prize of £20,000. There are ten contestants in this series, and they all carry large backpacks as they travel through different countries and face many challenges.

Watching themselves on TV has been a strange experience for both Katie and Harrison. Harrison says it feels like he is watching someone else, and sometimes he is surprised by what he sees. He laughs at some moments and feels embarrassed at others. Katie says she finds it funny to watch the show because she remembers how stressful it was at the time, but now she can enjoy seeing what happened. The siblings say they know each other very well and sometimes tease each other, but it makes their relationship stronger. The final episode of the show will be on BBC One, and viewers can also watch it online. Katie and Harrison are glad they took part in the adventure, and they hope people enjoy watching their journey.
