Next, register for the event by prepaying at There is typically a registration limit of 70 drivers, but we do accept walk-up registration at the event.

The event registration fee ranges from $65 to $75 for PCA members. Entrants are not required to perform a work assignment. A “gourmet” food truck will be available and at least an hour lunch break will be provided.

Each contestant must wear an approved helmet in good condition. Acceptable approvals are the latest or next two most recent (2015, 2010, 2005) SA, M or K Snell Memorial Foundation, FIA 8860, SFI 31.1 and BS6658-85 Type A-FR approvals. Loaner helmets are available free of charge. If you do not have a helmet, there are “loaner” helmets available free of charge at the event.

If you want to purchase a helmet, consider contacting Lone Star Region’s partner, PerformanceStop. They will bring samples to you and fit the helmet.

Before each event begins, there is a guided course walk that takes beginners step-by-step through the driving line and explains how to navigate through the cones. This is especially helpful for first-timers and those that want a second perspective. The course layout changes each event.

Finally, all cars must have a technical inspection at Lone Star Region PCA events prior to the first-course run. Tech is done at the event site.

There will be 6-8 competition runs and the event will usually conclude by 3:00 pm.

We provide trophies for every class with three or more participants.
