Shroomless gap jump after the first right split
Take the right path, release an orange mini-turbo around the turn, steer left and trick off the road edge to land on the other path - a fast path switch that becomes basically unfailable if you charge jump the gap instead.
Ending wall-and-pole turn skip
Near the end, land from the big glider section on the far left as early as possible, neutral charge jump off the road edge, right trick onto the right wall, trick off its highest point, left trick off the pole and land back on the road - the biggest time save on the track and the most important cut to learn. A safer variant keeps the glider along the left wall before tricking onto it.
Warp star glider dip
Going into the warp star after the neon section, hold down on the glider so it lifts you slightly; a small but race-deciding time save.
Hidden cut and post-split path switch
After the trick, drift and mini turbo trick using a mushroom to cut the corner.
Section-2 feather turn skip
On the section-two split paths, stick left, set up wide-tight-wide, sharp left drift, trick off the ledge and feather for an effective turn skip. Lakitu is very strict here, so it takes practice.
Post-item-set feather skip
Right after the item set, charge jump off the ledge and feather in the air for a very simple turn skip, with another item box available right after.
