The best of the reality series crop is back, with 12 teams of 2 players each racing around the world, trying not to be eliminated at a series of checkpoints in which the last team to arrive is booted from the show.

This season includes such duos as two circus clowns, a gay married couple, a father and son, a recently engaged couple, married couples, and best friends.
