The 100th Annual Loudon Classic Middleweight Grand Prix hits the 1.6-mile full road course on Saturday, June 17. Riders from all over the world will compete to take home a piece of the $250,000 purse with $55,000 going to the winner. Known as the longest-running motorcycle race in America, the Classic has been held on site since long before the speedway was built, when it was simply a road course known as Bryar Motorsports Park. The weekend will feature Northeast Motorcycle Road Racing competing in round three of racing (June 16-18).
