"The Amazing Race" returns with new cast

It's on your marks, get set, go for another season of "The Amazing Race."

The CBS competition series is back for its 23rd installment, with 11 new teams embarking on a race around the world for a chance at winning $1 million.

This season will follow teams through four continents and nine countries, spanning more than 35,000 miles. They'll paraglide above the skies of Iquique, Chile, subject themselves to a bone-chilling plunge in Norway and buckle up for Formula One Racing in Abu Dhabi.

"The Amazing Race" is also bringing back last season's Double Express Pass twist. Whichever team wins the first leg of the race will receive two Express Passes -- one to keep, and one they must give to another team by the fifth leg of the race.

Two former NFL teammates are among this season's pairs, as well as a set of baseball wives, married ER doctors, a former couple and the self-proclaimed "Queens of Bingo." Click through the slideshow above to see them all.

The new season of "The Amazing Race" premieres Sunday, Sept. 29, at 8 p.m. ET on CBS.
