On Sept. 30, 11 teams will start a journey around the world with hopes of clenching the CBS show's largest prize ever: $2 million.
So, who will be racing?
Season 21's teams include twin sisters from Sri Lanka; a pair of musically-inclined Chippendales dancers; and married Monster Truck racers.
There's also a heavy metal rocker from the band Megadeath; goat farmers (and stars of The Fabulous Beekman Boys, Josh Kilmer-Purcell and Brent Ridge); a competitive lumberjack and a double amputee.
"At 19, my life took a detour when I got bacterial meningitis and lost both my legs below the knees," says Amy Purdy, 32, who is a motivational speaker and snowboarder, in a preview of the season. "I wasn't sure I was going to be able to go on and compete in snowboarding and travel and do all the stuff that I love to do. But with a lot of hard work and creativity ... I've been able to go on and become one of the highest ranked adaptive snowboarders in the world."
"They come from different walks of life," host Phil Keoghan says in the video. "But they share one thing in common – they want to win."
But getting the $2 million prize won't be easy: The team that wins the first leg of the season must win the final leg of the Race to get $2 million rather than the usual $1 million grand prize.
According to a press release from CBS, "Teams will travel through three continents, nine countries and cover more than 25,000 miles, where they'll be faced with a 10-story rappel in Los Angeles, frying an egg on their heads in Indonesia, working as 'rat collectors' in Bangladesh and revisiting one of the Race's most infamous Roadblocks in the Netherlands in this season's Switchback."
