  • HPDE 1 – This is where you need to be if you are new driver. HPDE includes a minimum of (4) 20 minute sessions, or (3) 30 min sessions. All HPDE 1 students will be automatically assigned an instructor for the weekend. This event will follow a lead follow format due to covid-19. This includes required download sessions following each event. Please print HPDE tech form below and bring it with you to the track.
  • HPDE 2 – For drivers that have been signed off to drive on their own, but just want more time with the novice group. Groups 1 and 2 run together. The only difference is that Group 2 has no instructor assignment.
  • HPDE 3 – Groups 3 and 4 may also run together, typically arranged by fastest vehicle. Saturday will work up to additional passing by the end of the day. Sunday will be a continuation, starting with limited passing in the first session and then adding more passing zones and picking up the pace as the group leader feels appropriate.
  • HPDE 4 – Open passing, still monitored by group leader. May run with Time Trials.
  • Time Trials (TT) – TT license is required to register. All TT participants must have a transponder and display proper NASA decals.
