Here is some helpful advice for the skating events in the game if you plan to run any of them.

Speed Skating 500m - To be near the top, you should be able to mash L and R really quickly. Keeping up a good rhythm is also really important. Ignore the CPU in the opposite lane, as it can't affect your run. Turns are done automatically in this event, so you don't need to worry too much about that. You are able to dash up to two times depending on how fast you are out of the corners, as well as a final dash on the last straight, so be ready to react fast when the game tells you to dash.

Short Track 500m - This track has shorter straights, is narrower, and isn't as reliant on speed. The most important part I think is being able to get the best exits from cornering. Go as wide as possible in a turn, without hitting the wall, then turn as tightly as possible, although going too tight is actually slower, as you would hit an invisible barrier on the inside of the track. You are given the ability to dash on the final lap, however, don't use it until the last turn. You may also have to hope on a little bit of RNG, as if you are unfortunate, the CPUs might get in your way and slow you down.

Intense Short Track - Mashing speed and good rhythm are probably the most important parts of this one. Tight turning is again important however. Here you are given a special dash. You are limited to how many times you can do this by a heart depletion, but there's heart refills throughout the track. The CPUs can create bottomless pits near the end of the course, however you should be able to easily dodge them. There's also a massive hole near the start, which is covered off on the first lap, but you may need to change it's pattern on the second lap by going over a switch.

Hope this helps you.
