Celebrity Race Across the World - All Seasons

The famous faces embarking on their travels are, broadcaster Alex Beresford and his dad, Noel; singer Mel Blatt and her mum, Helene; McFly drummer Harry Judd and his mum, Emma and British Racing Driver and pundit Billy Monger and his sister, Bonny.

Starting in Marrakech, Morocco, the most north-western country in Africa, and ending in Tromsø, Norway, known as the Arctic capital, the epic journey will span 24 countries and over 10,000 km. The route will see the pairs race through every landscape and culture that this part of the world has to offer: from the great North African city of Marrakech, through the seaside ports and beaches of the Mediterranean, to unrivalled historic and cosmopolitan cities, the mighty Alps, unexplored Central Europe, the fairy-tale Baltic States, and snowy Scandinavia.

The four new famous faces embarking on an epic 12,500 km race of a lifetime are: broadcaster Jeff Brazier and his son, Freddy; actor Kola Bokinni and his cousin, Mary Ellen; broadcaster Kelly Brook and her husband, Jeremy and Radio 2 host Scott Mills and his husband (then fiancé), Sam.

Their journey begins in Belém, Northern Brazil - the gateway to the Amazon - and will pass through five checkpoints across the length of South America, to reach the finish line in the Andes, Frutillar in Southern Chile.

Our familiar faces will say goodbye to lavish transport, smartphones and bank cards and instead must rely on their skills, cunning and ingenuity as well as the kindness of strangers.

Once again, joining the celebrities will be their nearest and dearest, providing a unique insight into people we thought we knew, through the eyes of those who know them best.
