The Reno Air Races, officially known as the National Championship Air Races, are a multi-day event tailored to the aviation community that took place each September at the Reno Stead Airport a few miles north of Reno, Nevada, with the last races held in 2023. The Reno Air Racing Association plans to resume racing at a new venue in 2025. Air racing is billed as "the world's fastest motor sport" and Reno was one of the few remaining venues. The event includes races in six classes and demonstrations by airshow pilots.
