The concept is simple, ride more bulls for 8 seconds than all the other bull riders. It becomes a little trickier when the other riders are the Top 35 bull riders in the world, and the bulls are the fiercest on the planet. It is the Professional Bull Riders Last Cowboy Standing, a progressive-elimination event that takes place in a single day. The unique event has each of the 35 riders getting on a bull in Round 1. Riders who reach 8 seconds in Round 1 will advance to the next round, where they will each ride another bull. The elimination format continues until there is only one cowboy left. There will be a maximum of five rounds.
