In this event, the player starts by charging up their character by pressing and holding when "Ready?" is displayed onscreen, and starts the race by releasing it once "Go!" appears. The longer the player holds the button, for the more speed the character will start the race with. The player can also perform a Rocket Start by releasing at the exact same time as when "Go!" appears, giving them a large speed boost to start the race. Once the event has started, the player must quickly press to cause their character to accelerate. Their speed is indicated by the color and type of trail following the character, with white smoke indicating a low speed, blue flames indicating a moderate on and red flames indicating the fastest. The player can also press to perform a Super Dash, which can only be performed once during a race and causes the character to quickly accelerate to maximum speed, indicated by the word "Max" appearing on their trail.
