The ten remaining teams continue racing in Cartagena, Colombia, where claustrophobia threatens to prevent one racer from going deep into catacombs to retrieve a clue.
All eleven teams continue on through to the second leg, travelling to Cartagena, Colombia for the first time. One team scrambles to catch up from behind after they miss a crucial flight, while other teams get down and dirty at a Roadblock. After teams are able to find an emerald buried within the mud pool at the task, they can then swim out into the ocean and grab their next clue.
Teams encounter a Detour that requires specific attention to detail. One task has teams building a stable shelter on the beach for an outdoor beach party, while the other gives teams an opportunity to utilise their cooking skills to prepare a dish for party goers. After a scramble, the team stuck behind manages to catch up and pass another team due to a mistake, resulting in a close finish.
