Transcription:

To qualify for the AMA Amateur National Motocross Championship at Loretta Lynn Ranch you must participate in the twostep qualifying process: the Area Qualifiers and the Regional Championships. To understand how the qualifying system works, it helps to know that the United States is divided into seven different geographical regions consisting of the Northeast, Southeast, Mid-East, North Central, South Central, Northwest and Southwest. STEP 1 - THE AREA QUALIFIERS In each of the seven regions there are a maximum of eight Area Qualifiers. Riders must attend an Area Qualifier and finish in an advancement position (see advancement chart below) to guarantee a spot into the Regional Championships. At each Area Qualifier all classes will be offered and a two moto format will be conducted. Classes, however, may be divided between the two days, such as, limited classes on Saturday and modified classes on Sunday, so it is not necessary to be at the event both days depending on the class qualifying for. Riders may attempt to qualify in as many Area Qualifiers, in as many regions, as they choose. If a rider qualifies for the Regional, however, he/she must attend the Regional Championship for the region in which they qualified (see example below). The finishing positions guaranteed to advance to the Regional Championships from the Area Qualifiers are listed in the advancement chart below. IMPORTANT: Riders must receive a finish position in at least one moto in order to advance to the Regional Championship. STEP 2 - THE REGIONAL CHAMPIONSHIPS The Regional Championships are the 2 nd step in the process to make it to the "big show" at Loretta Lynn Ranch. Riders who place in an advancement position at the Area Qualifiers are invited to the Regional Championship, but must preregister with MX Sports by the deadline to keep that guaranteed spot. With the exception of the Northwest and Southwest regions, the Regional Championships separate the National classes into two different events: the Youth Regional and the Amateur Regional. The reason for the class separation is to accommodate the amount of riders that attempt to qualify, as well as the unique (3) three-moto format** at the Regionals. As a result, riders must attend both Saturday and Sunday to ensure all motos are counted towards an overall score. The finishing positions guaranteed to advance to the National Championship from the Regional Championships are listed in the advancement chart below. IMPORTANT NOTES: In some geographic regions there may be more than 40 riders eligible to participate in the Regional Championship. If there are more riders at the Regional than the starting gate can accommodate, then qualifying races will be run. Riders must receive a finish position in at least one moto in order to be considered as an Alternate for the National Championship. Riders who earn a guaranteed position in more than one Regional Championship will advance to the National from the rider's "home" region. If the rider did not qualify from his home region, then the selection will be from the region in which the rider had the better finish. If there are multiple equal finishes, then the rider will be selected from the region in which he first qualified. All riders will advance one position in a region in which an advanced rider qualifying in more than one region participated, whether selected from that region or another. **Northwest and Southwest Regional Run a (2) two-moto format.
