Superleg

Some Races have included a "double-length leg" Season 6 introduced the first double-length "superleg" shown over two episodes. The televised episode ended with a 'To Be Continued' message instead of a Pit Stop. The second half of the leg featured a second Detour and second Roadblock.

Occurrences
Seasons 7, 8, 9, 14 and 22 each had a superleg with teams meeting Phil on the usual Pit Stop mat at the halfway point, only to have him hand them the next clue instead of checking them in. In Season 10, the superleg did not involve meeting Keoghan, but rather teams were informed to "KEEP RACING!!!" in their next route marker. In addition, the 2-hour finale of Season 8 took place over a superleg similar to Season 6's. The first leg of Season 18 ended with a superleg, but the first team to arrive, Gary & Mallory still received an Express Pass from Phil after finished that leg. Likewise, the fourth leg of Unfinished Business also ended with a superleg and Margie & Luke won a vacation for coming in first. The ninth leg of Season 19 ended also with a superleg and Amani & Marcus won also a vacation coming in first.

In the international versions, double-length legs appeared in seasons 1, 2 and 4 of the Asian version (known as "Virtual pit stop" in the Asian version); the second season of the Latin American version, where it was similar to the Family Edition of the U.S. version, both seasons of the Australian version, the first season of the Vietnamese version and the first season of the Filipino version.

Clues
Generally, the clues leading up to these longer legs are easy to identify because the teams will read a clue like "Go find Phil at the mat" instead of "Check into the next Pit Stop." While there was no set rest period between the two parts of these legs, there usually is some point for the teams to eat, rest and recover prior to the second set of tasks, either due to waiting for hours of operation with provided accommodations or a long train or plane ride.

"To Be Continued"
"To Be Continued" legs appeared to be born out of sheer luck during Season 6. Leg 6 in Hungary was originally planned to be two legs, with a non-elimination point (with the stripping-of-all-cash rule in place) between the legs. However, the producers discovered during the race that begging is illegal in Hungary, which would have made it nearly impossible for the last place team to acquire the money needed for the upcoming leg, and quickly devised the extended leg to mimic the effects of a non-elimination leg (keeping the same number of teams in the race), and using a simple video message clue to provide teams the goal for the first task of the second half of the leg.1
