The Amazing Race 21 Cast

These 11 teams will travel through three continents, nine countries, and cover more than 25,000 miles on the 21st installment of "The Amazing Race."

This season will introduce a new twist to the game that will raise the stakes for the entire season. If the Team that wins the first leg of the season can outrace the other 10 Teams and win the final leg of the Race, they will double their money and win a $2 million dollar grand prize instead of $1 million.
