The Amazing Race 8 (titled The Amazing Race: Family Edition ) was the eighth installment of the popular reality television show, The Amazing Race . The Amazing Race 8 differed from previous installments of The Amazing Race in that instead of pairs of adults with a pre-existing relationship, this race featured families of four and allowed the participation of minors as young as 8. The Race returned to the original teams of two adults for The Amazing Race 9 . In addition to also having easier challenges, the Race also placed less emphasis on international travel as numerous legs were contained within the continental United States, and all race locations were inside North America.
