400m

400m (or 400m Dash) is an Athletics event in both versions of the game, Mario & Sonic at the Olympic Games and can be found in the "Track" section of the "Athletics" category. The goal of the event, is to reach the finish line first. The smaller version of this event is 100m.

Wii Version
Racers will begin the race at their respective starting line. When the announcer announces On Your Marks and Get Set pressing "B" on the Wii-mote will cause the character to ready him/herself and build up for a Start Dash. Once Go appears on the screen, releasing "B" and swinging down the wii remote will give the player a boost. Running is controlled by alternating the movement of the wii-mote and Nunchuck (or just the Wii Remote if not using the nunchuck). Pacing oneself is the key to this event. A gage appears above the controlled character and when the racer begins to sprint (the speed meter is full and the character gains a bluish glow) their stamina begins to drain. If a character's stamina is depleted, he/she will slow to a walk until their meter replenishes. At the last 100 meter (straightaway) the participants will sprint their way to the finish line.

DS Version
The event properties are the same in the DS version. The start dash however is preformed by touching the touch screen with the Stylus and then releasing it when the gunshot is heard. Running is controlled by rubbing the stylus across the touch screen. The speed of the runner is determined by how fast the stylus is swiped across the screen.

Description
Wii version: ''From a staggered start, kick off from the starting blocks, then endure a 400 meter run to the finishing line. The final 100 meter stretch should be sprinted to get you ahead of the competition, but take it slower at the start to avoid wearing yourself out.''

DS Version: In the 400m, it is vital to pace your stylus control so your character does not over exert themselves and lose speed.
