CBS on Monday revealed the 11 teams that will be competing on the 24th season of The Amazing Race.

This season will feature 11 duos who have previously competed on the reality show -- including the Globetrotters, the Cowboys, Brendon & Rachel and Dave & Connor -- returning for another chance at the $1 million prize.

The teams will travel through four continents and nine countries, spanning more than 35,000 miles, with challenges including a taking on mission high above the city in Guangzhou, China, rappelling down the roaring rapids of the Kiansom Waterfall in Malaysia, fighting with Gladiators in Rome, Italy and fueling up vehicles in Sri Lanka.  

In what CBS is calling a "dramatic twist," one team will not make it to the starting line.

Phil Keoghan returns as host of the series, which premieres at 8 p.m. Sunday, Feb. 23.
