Eleven new teams travel the globe, including stops in Indonesia and Malawi, in hope of winning the grand prize in the reality show's 19th season. Among the contestants competing are a pair of Olympians, a former NFL player and two winners of "Survivor." In addition to the physical and mental challenges the teams usually face along the way, this season they also contend with a new penalty called the Hazard, which impacts one team's future in the race from the starting line. The team that survives the weekly eliminations returns home with the $1 million grand prize. Phil Keoghan returns as host.
