Each Challenge of the Americas weekend will consist of a Friday practice day, which is divided into sessions by class.

If necessary, transponders will be used in the final hot pit session of the Friday practice day to set qualifying groups for any classes over 25 entries.  After the session, those classes, like all others, will be ranked according to fast time.  The fastest 50% of the field will be listed as Group A and the rest will be listed as Group B.  In the event there are an odd number of participants, Group A will have the greater number of participants by one competitor.  These will be the qualifying groups for both days.  Group B will qualify first and Group a will qualify second each day.

Saturday and Sunday are race days.  Each race day will consist of a warmup session, a qualifying session, a prefinal and a final for each class.
