In more recent seasons, extra envelopes are left in clue boxes to prevent this from occurring. version is to place the clue at the bottom of the Roaming Gnome, the mascot of Travelocity, the sponsor of the U. Route Information clues instruct the teams where to go next.In some cases, clues – most often of the Route Info type – have been provided by more unorthodox means, such as in an advertisement in a local newspaper or on some item related to the task just performed. Such a clue usually provides only the name of the team's next destination; it is up to the teams to figure out how to get there.
However, some seasons have introduced twists on this concept: the second All-Stars season featured a team made by the production due to illness befalling an original competitor while season 26, which has a theme of only people who are dating each other competing, featured five of the teams participating in a "blind date".
Dynamics of the relationship under the stress of competition is a focus of the show, and are often described by the teams during interviews held before, during, and after the teams have raced, and through discussion with the show's host when they arrive at the Pit Stop.
Contestants travel to and within multiple countries in a variety of transportation modes, including airplanes, hot air balloons, helicopters, trucks, bicycles, taxicabs, cars, trains, buses, boats, and by foot.
Clues provided in each leg lead the teams to the next destination or direct them to perform a task, either together or by a single member.
Most Route Markers are attached to the boxes that contain clue envelopes, but some may mark the place where the teams must go in order to complete tasks, or may be used to line a course that the teams must follow.
The original Route Markers used in season one were colored yellow and white.
When teams start a leg, arrive at Route Markers, or complete certain tasks, they normally receive a letter-sized tear-away envelope that contains their next clue inside a vertical-fold folder.
The clues themselves are typically printed on a vertical strip of paper, although additional information is often provided inside the clue folder.
Individual racers must be of a specific nationality and meet specific age requirements; this is necessary to allow teams to obtain the necessary passport documentation to travel across the world without incident. Four seasons featured an additional team of two (for a total of 12, instead of the standard 11), while the "Family Edition" featured ten teams of four players and included young children.
Season 29 featured 22 complete strangers who chose their race partners based on assumptions from a pre-race challenge.
They were changed to yellow and red in The Amazing Race 2, which has remained the standard Route Markers color scheme thereafter.
