In NASCAR, the 1-mile oval tracks are among the intermediate tracks. IndyCar rated this tracks as short ovals, since they usually do not run on ovals shorter than 3/4 of a mile. The one-mile ovals have lost a great deal of their former importance for oval racing. Most of the racetracks abandoned by NASCAR or IndyCar in the 2000s were of this type. These include the Chicago Motor Speedway and the Walt Disney World Speedway, which were built during the 1990s construction boom but only used for 4 years. The historic Nazareth Speedway, which was paved in 1986, was completely abandoned after the 2004 season. Physically, the Milwaukee Mile, the oldest oval race track in the world, as well as the Rockingham Speedway and the Pikes Peak International Raceway still exist. However, these racetracks have not been used by nationally important motorsports events for years. There are only three one milers left in the NASCAR racing calendar: Phoenix, Loudon and Dover. IndyCar has not been driving an oval of this length since 2018.
