CBS has formally announced the identities of the 11 teams who will be competing on The Amazing Race's seventeenth season, which will premiere with a special 90-minute episode on Sunday, September 26 at 8PM ET/PT.

Like all previous The Amazing Race editions, the members of the 11 teams -- which include three former beauty queens -- competing on the show's seventeenth installment have a pre-existing relationship with one another.  Three teams are dating couples, three more teams consist of family members, and five teams are friends or co-workers.

The Amazing Race's seventeenth season covered 32,000 miles and included visits to four continents and 30 cities. Several locations were visited for the first time in the reality franchise's history -- including Bangladesh, Ghana and the Arctic Circle.

In addition, the new season will feature a twist in which the team that finishes first during the Race's initial leg will receive "a surprise, game-changing advantage," according to CBS.

The Amazing Race's seventeenth season was filmed earlier this year and began in Gloucester, MA in late May.  Local eyewitnesses spotted the teams boarding local fishing boats that took them across the small seaport's harbor.  Once there, The Amazing Race host Phil Keoghan began the Race and the teams scrambled to drive themselves to Logan International Airport in Boston, where they boarded flights to England.
