Ending wall-trick cut
Faster but riskier: trick onto the pink rail, trick off its end with a right air trick, charge jump on the landing and left charge jump off the ramp, then hold right to get onto the wall as high as possible. Skips the item box, so it is best reserved for front running; more coins make the wall landing easier.
First-ramp cookie-wall grind to the high path
Off the first ramp, veer left to grind the ice portion of the cookie wall, jump off the second wall to reach the high right-side area, then follow the right-side guardrails all the way to the next ramp section.
Middle-path box break
Take the middle path and break the boxes for a small shortcut down the center.
Coin rail path with far-left rail landing
Instead of the glider, take the alternate rail path tricking on every coin (tough to get all of them), then aim very far left and mini turbo trick so the rail catches you and fixes your alignment.
