Monster Truck Challenge, originally known as Powertrax, was a half-hour weekly television show on ESPN, which featured primarily tractor pulling and monster truck racing.
The show began in the 1980s as Powertrax, with hosts Richard Leek and Army Armstrong, and would alternate between the two main forms of competition of TNT Motorsports: the Red Man Pulling Series and the Renegades Monster Truck Challenge Series, or a combination of both.
In 1991, the United States Hot Rod Association bought out TNT and decided to continue to use the half-hour format instead of their two previous shows. The show was renamed 1991 Monster Truck Challenge and used USHRA's Bret Kepner and TNT's Kris Chapman as host and pit reporter respectively. This format focused primarily on monster trucks, yet commonly showed mud racing highlights and tractor pulling. It was a condensed version of Super Trax, which was an hour in length.
The format was changed again in 1992, with Ken Broo as host and Joe Lowe providing voiceover for the races. Mud racing was often shown in highlight form at the end of each episode.
In 1993 USHRA decided to focus on the syndicated show Monster Wars, and Monster Truck Challenge was canceled.
