You need to do at least one session of races a day (5 + 2 from ads).

However, to get subgoals, you need to do at least 2 sessions a day (10 + 2 from ads).

You need subgoals to get extra rewards. You already get rewards, but subgoals give you more, especially boxes.

1671 is too low; you're going to need to be around 1720 or higher to finish the event, I think.

You need 26 engines to get to 10-0-10-0. You may need more for nitro upgrades if you're having difficulty.
