At long last, The Challenge is celebrating its milestone 40th season with a bang! In fact, the hit reality competition series features a record-breaking 40 contestants who are set to face off in The Challenge 40: Battle of the Eras.

This season, the contestants will be divided into four distinct eras based on when they first appeared on the show — Era 1 (Seasons 1-10), Era 2 (Seasons 11-20), Era 3 (Seasons 21-30), and Era 4 (Seasons 31-39). They'll then battle it out for a slice of the $1 million prize.
