Events Calendar

Diablo HPDE: Thunderhill (3 Mile)
Event Date: Friday 07 May 2021
Start Time: 8:00AM

This event is open to all Porsche drivers.  Only Porsche cars are allowed.

We are a Porsche club, not a driving school or a driving business.  We run several safe, fun and friendly track events each year. We do not race, time trial or time laps. We limit this event to 25 cars per run group so that we can offer plenty of room on track and lots of track time. The DE team will review all registered drivers and will confirm the run group classification for each driver based on overall track experience.  During the event the DE team will work to accommodate drivers wishing to change run groups, subject to approval by our Chief Driving Instructor (CDI).  

4 Run Groups: Beginner Lead/Follow, Beginner Solo, Intermediate, Advanced/Instructor 
(Note: Run group classifications may change depending on the number of cars registered)
  • Beginner Lead/Follow: Drivers with 5 or less track days, or have not been cleared to drive solo FULL
  • Beginner Solo or Intermediate: Drivers with 19 or less track days and have been cleared to drive solo
  • Advanced: Drivers with 20 or more track days or Instructor experience

Registration Fee: $425 for Beginner Lead-Follow Drivers, $375 for Solo Approved Drivers

  • Registration will close when the maximum driver count is reached, or on midnight April 30, 2021, whichever is earlier.
  • All registrations are considered preliminary until confirmed by the DE committee.  You will be notified once your registration is confirmed, or if you are wait-listed, or if we were not able to accommodate your registration for this event.
  • All refunds are subject to a $75 cancelation fee.  Sorry, no refunds after April 27, 2021.  
  • Instructors are $150  

Pre-Event Meeting

Our DE 101 pre-event Zoom meeting will be held on April 21 at 6:30pm.  Meeting details will be sent out via email.  We ask that every registered driver attend this event, but it is highly recommended for all new to DE drivers.

Safety Inspection Information:

All drivers must certify that their car has passed a safety inspection by an authorized person within 30 days of this event, per PCA guidelines.  The safety inspection form can be downloaded from our DE website ( All drivers must complete this safety inspection form to verify that the condition of their car is ready for the track. Well maintained Porsches should have no problem passing tech inspection if they have good brakes, tires, no oil leaks and no defects. If in doubt, have the experts look at your car.  

COVID-19 Related Changes:

Due to Covid-19 restrictions and requirements, this event will be run differently than pre-Covid-19 Diablo PCA DE events:

  • We are unable to provide in-car instruction due to COVID-19 social distancing requirements.  Instruction will be via Lead/Follow (Student following an Instructor driven car)
  • All participants will need to read, sign, and return specific waivers that will be provided before the event and also at the entrance of the race track.  
  • Event details, such as the DE 101/201 class, meals at the event, and general event logistics, will be communicated to registered participants as we get closer to the event date.
