The National Championship Air Races and Air Show feature several classes of up to laps aircraft racing together for up to eight laps around a closed course demarcated by specially marked poles [pylons] at speeds exceeding 500 mph. The event, held each September at Nevada's Reno Stead Field, also includes a large static aircraft display, aerobatic performances and flight demonstrations by military and civil aircraft, and related events.
