Gameplay
The event starts with the characters lining up on the starting line preparing to run. During this time, the player can hold to charge up their character. If they charge their character for long enough, they will perform a Start Dash. When the announcer says go, the player must release to start. The order in which the runners release the A Button determines their starting position at the end of the race. The camera then turns to depict the runners from the side, with the player who released A first leading, and the player must then quickly press to sprint to the finish. However, if they press the A Button too quickly too fast, their character will slow down again before they reach the finish, but will keep on running.

Controls
1) Start: Hold the A Button, and then release. 2) Final Sprint: Tap the A Button repeatedly. But sprint too much and you'll lose speed before the goal.
