Let's explore the different run groups for a typical Porsche Club of America (PCA) event. In this specific case, we're looking at the Kentucky PCA region event at NCM Motorsports Park in Bowling Green, KY. The event is set up to take a driver from the beginning stages of an HPDE, (where passing is limited and speeds are slower), to advanced running, (with higher speeds and open passing).

The KYPCA event is fairly typical for both Porsche events as well as other club events. Some groups add or subtract run groups, but all HPDEs, (High-Performance Driving Events), follow a similar template.
