RW/RR: Extreme Challenge

Extreme Challenge is the third and last 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.
