The nine winners reconvene for one last run through the Beast with the grand prize of $50,000 and the title of Ultimate Beastmaster on the line.

Nine new competitors face a Beast that's fiercer than ever. But only two will move on to the first semifinal round in "Beastmaster" history.

Two champion climbers are joined by a prizefighter, a powerlifter, a dance instructor, a surfer and others in a battle for two spots in the semifinals.
