"" continued the race in Argentina in its second leg, where the remaining teams must first head to Cafayate Town Square to get a clue delivered by a postman. Rachel and Dave, who won in the first leg, took off first but they lost their lead as they had to wait for quite a long time before the postman arrived.
The clue directed them to Detour, which was between "Boil My Water" or "Light My Fire". In the former, teams had to assemble a solar kitchen and boil a teakettle of water. In the latter, teams had to gather firewood and clay at a nearby river, load it onto a donkey, and then deliver it to a local pottery workshop. Almost all teams picked "Boil My Water", except Art and JJ who opted for "Light My Fire".
