The sanctioning bodies (NASA and SCCA) publish event weekend detailed schedules, with run groups. Each sanctioning body will have the latest version of their event schedule and supplemental rules.
Note: Test Days precede almost all Spec MX-5 Challenge weekends. These are sometimes run by the track, not the sanctioning body. They are sometimes run by a track day operator.
REMEMBER: all drivers must enter each race in which they intend to compete. This is done with the sanctioning body for each race (SCCA or NASA).
REMEMBER: to earn points, drivers must be entered in the run group that has the SMX or Spec MX-5 class. Drivers may also run in STL (SCCA) or ST5 (NASA), but unless they are running the Team Series, STL and ST5 are not points-scoring races.
REMEMBER: to score points, drivers must register their points with Spec MX-5 Challenge, LLC, the Series operator. This is completely separate from entering the races.
REMEMBER: points that apply to the championship can only be scored on Spec MX-5 Challenge Marquee weekends.
