The experiment nobody repeated.
The #13 slot.
Slot #13 of 38 in the Amazing Race Editor's Canon. Family Edition sits at the bottom of the canon because the format does not run cleanly in the configuration this season delivers. Ten teams of four — parents with their kids — ran an eleven-leg route that stayed almost entirely within the continental US, with short detours into Mexico, Costa Rica, and Canada. The four-person teams crowded the vans and slowed the airport-to-airport rhythm the audience had come to expect, and the domestic route gave up the geographic argument the show relies on. Phil Keoghan hosts with care. The canon places it thirteenth because the experiment never returned — and the franchise's reluctance to retry it is the verdict.
