The Challenge: Rivals is the upcoming twenty-first season of the MTV reality television game show, The Challenge, and follows Cutthroat. It will take place in Costa Rica and Argentina, with former cast members from MTV's The Real World, Fresh Meat, Fresh Meat II and the Spring Break Challenge competing. This will mark the first season of The Challenge to not feature a castmember from any season of the cancelled series, Road Rules. The season will feature a new format, pitting players who will be partnered with their worst enemies from past seasons of The Real World and The Challenge.
