Established in 2003 and featuring a unique and open, Pro/AM format, the US Open offers the most challenging and competitive racing in the nation and sets the standard as a proving-ground for up-and- coming and elite racers alike. Anyone can enter the Open Class and compete amongst the pros for the cash purse and a chance to prove where they rank. Amateurs compete for bragging rights and some of the best prizes in racing.
