There is a number of different "runs" that are pre-set, I think. Restoring to an earlier race in a run will make you run the same challenges again to the point where you had restored. As someone on the actual page said, the rolling of events is probably just for show.

I expect standard bot behaviour applies and winning big will make events harder, especially as there isn't an opportunity to slow bots down without spending Gold.

What I know is that there is a list of descriptions (i.e. "Win this challenge") that can be applied to any event and track. Boss challenges are always limited to "Win this challenge", Head to Head and Cup events.

Rewards are dependent on your Rank/Car Rota.
