Real World/Road Rules Extreme Challenge is the fourth season of the MTV reality game show, The Challenge (at the time known as Real World/Road Rules Challenge).
Extreme Challenge is the third and final six-on-six Real World/Road Rules Challenge. The cast was 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 challenges. Each time a team won an individual challenge, money would be added to a Monster.com team bank account. The last mission would be for the right to keep the money collected in the pot, an additional cash prize, and a car.
This was the only season without a regular alumni host/presenter introducing each challenge. Instead, various alumni provided audio clues.
