I believe it is just 1,000KM between all of your mileage put together and no it doesn't have to be on the same track.
You do have to do it where mileage is actually put on your car such as A/B Spec and practice mode.
I thought it was 2,000 kmYou can also earn a 1000 ticket by winning an event 100 times in any car, and it doesn't have to be on one event.
So it does have to be he same track then yeah?
