Episode 5

It’s the penultimate leg of the race and the longest so far. The teams must travel from the islands of Bocas del Toro on northern Panama’s Caribbean coast to Medellín, Colombia’s second-largest city. Standing in their way is the notorious and dangerous Darién Gap. Their only option is to bypass it by sea, enduring a lengthy, arduous and costly boat journey, putting their dwindling budgets under pressure.

On reaching the final country of the race, each pair is confronted with another challenge to overcome: a heightened security risk on the route to Medellín. Who will reach the checkpoint first to secure pole position going into the final leg?
