The second series had a thrilling finish with just seconds separating between the winners and the couple who came second.
This episode was a reunion show which took a look back at the adventure of the 5 couples that started the race, this time spanning South America.
They had to race through 17 countries and over 21,000 kilometres.
What struck out the most was a lot of the couples had issues. Emon and Jaimul the estranged uncle and nephew who had been apart for 10 years after a family dispute. Rob and Jen, a married couple with Rob having hearing problems. Jo and Sam are mother and son. Jo travelled in her younger days but has had health issues and Sam suffers from ADHD.
In the reunion show all of them talked about just how momentous the journey was and how unprepared they were such as dealing with language barriers. They had to constantly keep track of their finances, get food, work to earn money, rely on the kindness of strangers (easy to do when followed by a BBC camera crew) and plain old hustling.
There were downsides. One couple had to drop out as they lost their money belt. One couple were shocked by the poverty they saw in Brazil and decided to donate some of their winnings to charity.
It was an enjoyable second series and one that had a lot of heart and some thrilling moments.
