One of the first things you should do is, well, go straight for the circle. In Soaring 50s, the final circle will be in place pretty much from the beginning.

Sorry, this means you won't be able to explore season 6's new areas in this mode, maybe try Playground mode for that one.

Though it does also mean you're in for an intense battle - if the enemy battle bus ends up soaring over the circle before yours, or you jump out at a distance from it, you could find yourself in a risky situation.
