- HPDE 2
- HPDE 3
- HPDE 4


- HPDE 2
- HPDE 3

NO TT FOR THIS WEEKEND. But we have Open Track on Sunday!


Do not choose "instructor" below. One will be assigned to you automatically.


HPDE 2 is for drivers that have been signed off to drive on their own, but just want more time in HPDE 1. So, Group 2 is Group 1 (and runs with Group 1), but they have no instructor assignment. Please see this notice before signing up


There will be at least four 20-minute sessions. Please see the prerequisite page to make sure you are eligible.
Sunday only entrants MUST have completed a prior Sunday HPDE3 event to be eligible.


There will be at least four 20-minute sessions. Please see the prerequisite page to make sure you are eligible.



MIXED CLASS RACING MARATHON. No points, just fun racing in one group. All racing registrations will fall under this single run group.

Proposed schedule for this group:

Saturday: 20 min warmup, 20 min qual, 30 min race 

Sunday: 20 min warmup, 30 min qual, 30 min race, 30 min race, 30 min race (that's THREE races)

Weekend total is 210 minutes, or 3.5 hours of track time.  As much as the enduro!!!


Anyone may supersize into Open Track that has done at least one day at Sonoma with open passing rules. (excludes HPDE 1/2, and some 3 level drivers).


There is a 3.5 hr endurance race. A separate warm-up will be included.  Please see the new classing based mostly on Super Touring mapping.  



There is a STRICT sound limit of 101 dBA measured 50’ from the line on driver’s right, apex of T12.  Attempts to fool the meter or lift will easily be detected by the track’s dedicated sound person (they hate that!).  So, please prepare to adjust your muffling system if necessary.  This is the same standard that has been in place for years.
