A fourth class of racing in BMX which are held at local and national events are called Opens. Opens are largely exhibition and are a chance to test yourself and practice against better competition without jeopardizing your point standings. You must be registered to race in a points race to sign up for the Open events. No points are awarded for Opens although trophy places are and the moto qualification rounds are similar to the point races. These are races with more flexible skill level and age requirements. In Opens there are no Novice, Intermediate and Expert divisions. All amateur skill levels are free to participate. The age groupings are generally broader, for example 13-14 open class as opposed to 13 Intermediate and 14 Intermediate being separate groupings for those ages in the points races. Girls may also participate in the male Open class within the proper age ranges. However expert boys are not allowed in these "Mixed" opens. Then an Expert Open is held in that event. The pros are excluded from racing with the amateurs if enough pros are at hand to race that a separate Pro-Open class can be created. If not, then the pros can race in the amateur Open with some restrictions. This is called a Pro-Am event. Except for the Pro-Am exception the Expert racers usually wins the open class. Even if there are Pros in the Open, it is not unusual for an older Expert-17-18 age class for example-to win since many have the talent and speed to be a pro but have not yet taken the opportunity, partly because once you go Pro, you can go back to amateur only under very strict circumstances.
