The teams travel through the breathtaking beauty of Costa Rica, a country that contains five per cent of the world’s biodiversity, before reaching Panama, the seventh country of the race. The next checkpoint is Bocas del Toro, an archipelago off Panama’s Caribbean coast.

The race reaches its climax as one lucky team claims their title as champions of Celebrity Race Across the World.

It's a race to the finish line in Tromsø for the four celebrity teams. Which will get there first and be crowned champions?

The race to the Guajira Peninsula is under way. The teams can choose to travel through Guatemala, southern Belize or Honduras to reach the second checkpoint of El Zonte in El Salvador.

The teams will race from Tigre, on the banks of the Paraná River, high into the far north of Argentina and 2,500 metres above sea level, to the 10,000-year-old mountain town of Tilcara.

Taking on the race from Africa to the Arctic are McFly drummer, Harry Judd, British racing driver and pundit Billy Monger, singer-songwriter Mel Blatt and broadcaster Alex Beresford.

The race intensifies as the four pairs must leave Pinhão in Portugal’s Douro Valley, and navigate 2000km through Spain and France to the second checkpoint in Bonifacio on the island of Corsica.

Four familiar faces - Roman Kemp, Dylan Llewellyn, Anita Rani and Molly Rainford - set off with a loved one on an epic 5,900km race through Central America.

The teams reach the halfway mark, and after sixteen days traversing the length of Brazil, it’s time to cross the border and enter the heart of South America and three new countries.

As the teams approach the halfway point, they must navigate their way from the Mediterranean island of Corsica to the third checkpoint in Zermatt, a mountain resort nestled in the Swiss Alps.
