What is with these Cone Challenges? I can't seem to be able to beat the, on higher levels. How do I get better Kudos scores in these Challenges?

The trick is to not break combo during the entire lap, the bulk of the points will come from the multiplier. There will be a few places where combo cannot be kept ordinarily, so you will have to learn where these are and do some sort of slide to keep it alive.

Controlling your speed is also important. You need to keep it fast enough to make the next cone gate, but not so fast you lose control.

Cone challenges are hard but the trick is to keep a constant kudos going
