Join us for our 38th season of championship racing! Delta Speedway is a 1/7 mile dirt oval race track at the San Joaquin County Fairgrounds in Stockton, California. We race micro sprints in the Junior Sprint, Restricted, Non-Wing and Super 600 classes. Delta Speedway is an affordable place to take the family for an evening of exciting wheel to wheel action! Be sure to join your friends on Saturday nights from April to October for great food at Royce Farms BBQ, fast cars and fun!
