Real World/Road Rules Challenge - 4. sezóna (2001)

Extreme Challenge is the 4th season of the MTV reality game show, The Challenge. The season is directly subsequent to Real World/Road Rules Challenge 2000. Extreme Challenge is the first season that adorned the show with a subtitle, the series having begun a new trend of titling each season based off its format and theme. To date, it's also the only season in which the season title alters the show title, through the insertion of "Extreme" between "Real World/Road Rules" and "Challenge." Extreme Challenge consisted of the third and final six-on-six Challenge. The casts were split up into two different six-person teams, one representing The Real World and the other representing Road Rules. The teams traveled via tour bus in the eastern U.S. and Europe competing in different individual challenges. Each time a team won an individual challenge, money would be added to an E-Trade account. Each time they won a challenge, they had the chance to invest those winnings in the stock market for the duration of the challenge. The last mission would be for the right to keep the money collected in the pot, an additional cash prize, and a car.
