Bandimere Speedway, also known in the NHRA as Thunder Mountain, is a quarter-mile dragstrip located just outside Morrison, Colorado and Lakewood, Colorado. It opened in 1958 and hosts the NHRA's Dodge//SRT Mile-High Nationals. The facility has a seating capacity of 23,500 spectators. In April 2023, it was announced that Bandimere Speedway would be closed at the end of the 2023 season, with the intent to move the speedway elsewhere.
