Bandimere Speedway, also known by the NHRA as Thunder Mountain, was a quarter-mile dragstrip located just outside Morrison, Colorado and Lakewood, Colorado. It opened in 1958 and was the host to many racing events, including many NHRA Nationals events. 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.
