The Head-to-Head forces teams to compete against each other one-on-one in a specific task. The winning team is given the next clue (or is allowed to check in at the nearby pit stop), while the losing team(s) must wait for the next team's arrival to start the task over. In one variation, the Head-to-Head appears in the middle of a leg, and the team that loses the last round will often receive a penalty — most often a predetermined time penalty — before receiving the next clue. In another variation, introduced in Season 30, the Head-to-Head was placed immediately before the pit stop, with winning teams allowed to check in and the last team remaining declared to be in last place. This was first introduced in second Latin American version as the "Intersection" (not to be confused with the collaborative obstacle outlined above), and it has appeared in other versions under different names, including "Double Battle" (Israeli version), "Face Off" (Canadian and Chinese celebrity versions) and "Duel" (Philippine version).
