Off-road racing is a format of racing where various classes of specially modified vehicles (including cars, trucks, motorcycles, and buggies) compete in races through off-road environments.
The first recognized off-road racing sanctioning body in North America was the National Off-Road Racing Association (NORRA). The body was formed in 1967 by Ed Pearlman. The first event was a race across the Mexican desert. The event was first called the Mexican 1000, and it later became known as the Baja 1000. The event is now sanctioned by SCORE International.
In North America there are several other formats. There are races on a circuit of less than five miles (such as Crandon International Off-Road Raceway), which are sanctioned by CORR (or its predecessor SODA). Another format made popular by the Mickey Thompson Entertainment Group was called stadium racing, where offroad racing vehicles were used in a temporary offroad racetrack was constructed inside a stadium. The general idea of "offroad racing" can also extend to include hillclimbing or any other form of racing that does not occur on a specified, paved track.
