The Challenge Cup Series consists of at least 10 events per year. These autocross events are great fun for all types of drivers and cars. Your quickest time through a course is what is used to determine your finishing position. Then series points are applied based on your finish. Example: 1st place gets 10 points, 2nd place gets 9 points, etc.. The one with the most points in that class at the end of the year is the Challenge Cup Winner.
The Rapide PAX Series for 2021 provides more track time. This event is held at the same time as the Challenge Cup event and runs the same course but your fastest time is multiplied by an index. This index, (2021 PAX index ), is designed to equalize cars so that all cars can be compared to each other. Winners per event are awarded cash prizes for the first 20 places, (based on entry count), and points are applied toward year end series points.
