The H.O. Professional Racing Association (HOPRA) provides the leadership for organizing H.O. scale racing in the best possible way. For over 45+ years, we at HOPRA have been scheduling races and championships to give race fans and H.O. enthusiasts the opportunity to become more involved with scale auto racing and add to their enjoyment of racing and H.O. cars.

Established in 1969, HOPRA has been dedicated to the promotion and advancement of H.O. slot car racing and has run many state championships and larger races throughout the country. Starting in 1975 and every year since, HOPRA has held its annual National Championship event that draws the best H.O. slot racers from around the world.

As the only independent organization that deals with H.O. scale slot car racing on a National level, we have rules and guidelines established by leading groups and individuals from across the United States.
