The Professional Bull Riders Challenger Series is the top expansion series of the PBR. It features some of the best athletes of the sport going head-to-head with the fiercest bulls in the country. The PBR Challenger Series will bring all the high-energy sound, lighting, special effects, and edge-of-your-seat action that fans have come to expect from the World leader in the sport of bull riding. The PBR is NOT a rodeo format - it's two hours of pyro, music and the most intense bull riding action the world has to offer, filled with heart-pounding, bone-crushing action, and a star-studded line up of the world's best riders and animal athletes.
