The Tucson Raceway Park has recently laid a clay surface to allow dirt tours at the raceway. The track was originally a clay oval built in 1968, which was later changed to an asphalt surface. Races are held each Saturday night from February to November and practice sessions run on a Friday. The track only closes on weekends if a Sprint Cup race is held in Phoenix.
Along with the clay track at the raceway is a 3/8 mile paved track. The track will now host X-Mods, Factory Stocks, Hornets and Arizona Mod-Lites when the new dirt surface is fully opened. A Super Stock Race along with twin 25 lap topless modified races is held on the paved track. The track will use UMP style rules for the modified open competition.
One of the highlights help in September 2010 was when the dirt surface officially opened and Metal Mulisha hosted their huge FMX Jump Show. This included free entry for all military personnel.
The Tucson Raceway Park hosts NASCAR Races, demolition derbies, motocross, monster trucks and many other special events for visitors who love motor racing. The park also relies on sponsorship to help the park host these races; these include Drive Tech Racing School and The Official Graphics Company for TRP.
