Knoxville Raceway is known as the sprint car capital of the world, which has earned the track a solid reputation as the fastest half-mile dirt track in the nation. The last AMA Pro Half Mile National Championship was held in 1996 and won by Nine-Time Grand National Champion Scott Parker. Due to construction and time concerns the opening round in Daytona Beach originally scheduled as a TT event has been replaced with a Short Track National. The all new quarter-mile dirt track at Daytona International Speedway located outside NASCAR turns 1 & 2 will have seating for more than 5,000 spectators and will have lighting provided by Musco Lighting."Since we released the first 2010 AMA Pro Flat Track Grand National Championship schedule, we’ve received even more interest to be part of our growing series," said Mike Kidd, Director of AMA Pro Flat Track. "The addition of Castle Rock helps our mid-season west coast swing and including Knoxville is certainly going to enhance the series."2010 AMA Pro Flat Track Grand National Championship ScheduleMarch 3DAYTONA® Flat Track (Daytona Beach, Florida) Short TrackMarch 4DAYTONA® Flat Track (Daytona Beach, Florida) Short TrackMay 1Yavapai Downs (Prescott, Arizona) MileMay 29Illinois State Fairgrounds (Springfield, Illinois) TTMay 30Illinois State Fairgrounds (Springfield, Illinois) MileJune 5Gas City I-69 Speedway (Gas City, Indiana) Short TrackJune 19The Red Mile (Lexington, Kentucky) MileJune 26Allen County Fairgrounds (Lima, Ohio) Half-MileJuly 10I-96 Speedway (Lake Odessa, Michigan) Half-MileJuly 25Castle Rock Fairgrounds (Castle Rock, Washington) TTJuly 31Calistoga Fairgrounds (Calistoga, California) Half-MileAugust 7Hagerstown Speedway (Hagerstown, Maryland) Half-MileAugust 14Beulah Park (Grove City, Ohio) MileAugust 22Peoria Race Park (Peoria, Illinois) TTAugust 28Indiana State Fairgrounds (Indianapolis, Indiana) MileSeptember 4Illinois State Fairgrounds (Springfield, Illinois) Short TrackSeptember 5Illinois State Fairgrounds (Springfield, Illinois) MileSeptember 11Canterbury Park (Minneapolis, Minnesota) MileSeptember 18Knoxville Speedway (Knoxville, IA) Half-MileOctober 9Yavapai Downs (Prescott, Arizona) Short TrackOctober 10Yavapai Downs (Prescott, Arizona) MileAMA Pro Racing is the premier professional motorcycle racing organization in North America, operating a full schedule of events and championships for a variety of motorcycle disciplines.
