Celebrity families line up for Race Across The World
Beresford will be joined by his dad Noel, while Judd will team up with his mum Emma. Singer Mel Blatt will also be taking part with her mum Helene, and British Racing Driver Billy Monger with his sister Bonny.
Hot on the heels of the emotional roller-coaster that was series three, the celebs will be taking on the same epic challenge but racing a different route.
This time they will start in Marrakech, Morocco, the most north-western country in Africa, and end in the Arctic capital of Tromsø, Norway, in a journey that spans 24 countries and over 10,000km.
