Watch The Challenge series free. The Challenge (originally Real World/Road Rules Challenge) is a reality television game show on MTV that is both dependent on and spun off from the network's two flagship reality shows, The Real World and the now cancelled series, Road Rules. It is currently hosted by T.J. Lavin. The Challenge has developed a spin-off series in its own right, Spring Break Challenge. The Challenge and Spring Break Challenge have a somewhat cast-contestant interdependent relationship in that both programs have used at least one or more contestants from the other.
