This is unknown.

The in-game text does say that you'll get a chance to win all 4, but, if you only unlock 1 stage per day (for all the cars) there's not enough time in the advertised window to run it 4 times.

The last NASCAR event (FAP400) only allowed us to unlock 1 stage per day for all 4 cars.

The previous event which was similar (Le Mans: POV) did allow later run-throughs to be completed more quickly and stages were automatically unlocked (for cars 2 and 3).

Given the lack of information on this from FM we probably won't know until Monday when the first group of people get to finish their first run through.

Either way (stage per day or auto-unlock), you should have enough time to run through at least 3 times.
