Taking on the race from Africa to the Arctic are McFly drummer, Harry Judd and his mum, British racing driver and pundit Billy Monger and his sister, singer-songwriter Mel Blatt and her mum and broadcaster Alex Beresford and his dad.
The race ramps up. Leaving Pinhão in Portugal's Douro Valley behind, the four pairs must reach the second checkpoint in Bonifacio on the island of Corsica by travelling through Spain and France. Which pair will reach the checkpoint first?
As the teams approach the halfway point, they must travel from the Mediterranean island of Corsica to the third checkpoint in Zermatt, a mountain resort nestled in the Swiss Alps. But only 3 teams have reached the checkpoint in Corsica.
The race has reached its fifth and penultimate leg as the four celebrities and their loved ones navigate their way 1500km north from Sarajevo to Germany's capital, Berlin.
It's a race to the finish line for the four celebrity teams. Which will get there first and be crowned champions? With budgets critically low and the teams only separated by a few hours it is all on the line.
