Editing 400m (Mario & Sonic at the Olympic Games for Nintendo DS)

This event starts with the characters and their randomly chosen lane positions being announced, before showing the player in their starting position. When "Ready?" appears on the screen, the player is then able to touch and hold the stylus to the Touch Screen to charge up power, allowing them to perform a faster start. Once "Go!" appears, the player can slide to the right to start running in the event. If the player slides too early, the player will commit a foul and the event will be restarted, though if they perform a foul twice they will be slowed down by a [[Boo]]. Once the player has started the race, they must constantly slide left and right on the touch screen to build up speed. Sliding faster will cause the character to accelerate, while releasing or sliding slower will cause their speed to decrease. The player only has a limited amount of stamina, and if it is all used up the character will stagger, causing them to lose most of their speed but fully refilling the stamina level. The speed at which the character is going is indicated by a meter in the top left corner of the upper screen, with a yellow line and purple section near the end indicating the speed at which the character will begin to lose stamina, touch running at a lower speed than this will not decrease the character's stamina at all. During the final sprint, the stamina meter is removed and the player is able to run as fast as possible without losing stamina. Just before the finish line, the player is also able to tap the touch screen to lead with their chest and give them a slight boost as they cross the finish line.
