In episode 1, the pairs kickstart their journey in the far north of Brazil in Belém, the capital of the state of Pará.
After handing over their belongings, the teams were given a GPS, map, spending money and the all-important details of their first checkpoint.
On their journey, their first checkpoint is Canoa Quebrada, also known as the pearl of the east coast in Brazil.
The teams will need to travel 1,750 kilometres through four states to reach the first checkpoint. To get there, they could go through the Atlantic coast or they could head inland to save money and travel through the rural back country.
While battling the tropical heat, the teams must work out how to reach Canoa Quebrada, in a place where only 5 per cent of the population speak English.
As ever, the teams must pass through five checkpoints, and only when they reach one will they know where the next will be.
