CBS has formally announced the identities of the 11 teams who will be competing on The Amazing Race's 25th season this fall.

The upcoming season, which began filming in Times Square in New York City this past Saturday, will feature all new teams and air on Friday nights from 8-9PM ET/PT.

However, one of the teams will be familiar to reality TV viewers. Keith Tollefson and his now-fiancee Whitney Duncan had both competed on Survivor: South Pacific. The couple got engaged in February 2013 after falling in love while filming Survivor in Summer 2011 when Whitney, who is also a former Nashville Star finalist, had been secretly married.

The Amazing Race's 25th season will continue to feature teams participating in a series of challenges -- some mental and some physical -- as they race around the world in the hopes of crossing the finish line in first place and winning $1 million. Phil Keoghan will return as host.

CBS considers its 25th season a milestone. The last 24 editions have chronicled 234 teams; 770,000 miles traveled by Racers; 84 countries visited; 286 Roadblocks; and 12 visits in China. China is the most-visited country on the Race.
