The Grand National Cross Country (GNCC) Racing Series is one of the premier off-road motorcycle and ATV racing series in the world. Emerging from the vision of Dave Coombs and his legendary Blackwater 100 dirt bike race, GNCC quickly captivated the spirit of endurance off-road racing and sported both dirt bike and quad classes, spawning legendary racers such as Scott Summers, six-time ATV champion Bill Ballance, William Yokley and countless others. Today, the GNCC race series has earned a huge following of ATV and motorcycle enthusiasts alike and is sanctioned by the American Motorcyclist Association (AMA).
