Mission Valley Speedway went from a 1/4 mile track to a 3/8 mile track in 1996. It was resurfaced and made into a 14 degree high-banked, tri oval asphalt track. The track has been through many changes and was even shut down for a few years. But racing in the valley is very important and as a racing family needed to be brought back. We have been running strong for the past couple of years and continue to make improvments and strive to grow each year!
