What is the amazing race season 4?

The Amazing Race season 4 aired from May 29 to Aug. 21, 2003. The show featured 12 teams of two each, starting from Southern California and traveling over 45,000 miles across 4 continents and 24 cities. The teams were required to complete various physical and mental challenges and race to each destination, all while avoiding elimination.

The season was won by Reichen Lehmkuhl and Chip Arndt, a gay couple from California. They received $1 million as the grand prize. The season also featured a controversial incident where one of the teams, Millie and Chuck, were asked to leave the race after breaking the rules by hiring a taxi driver to guide them to a destination.

Other notable teams in the season included married couple Jon and Al, father and daughter team Kelly and Jon, and cousins Steve and Dave. The season had its share of exciting moments, including bungee jumping, navigating a crowded marketplace in India, and rowing a boat across a river in Vietnam.
