Quarter midget racing is a form of automobile racing. The cars are approximately one-quarter (1/4) the size of a full-size midget car. The adult-size midget being raced during the start of quarter midget racing used an oval track of one-fifth of a mile in length. The child's quarter midget track is one quarter that length, or 1/20 mile (264 feet). The drivers are typically restricted to ages 5 to 16. Tracks are typically banked ovals one-twentieth of a mile long, and have surfaces of dirt, concrete, or asphalt.
