Editing 4x100m Relay (Mario & Sonic at the London 2012 Olympic Games for Wii)

This events starts with each of the players' team leaders being announced, before showing them on the starting line. Before the race starts, the player is able to hold {{button|wii|B}} to charge up and get a short boost. When the word "Go" appears on screen, the player must swing down the Wii remote to start the event. Doing so with perfect timing grants the player a starting dash. The player must then constantly shake the Wii remote as fast as possible to cause their character to run. The player is also able to perform a special dash at any point in the event to give their character a short speed boost by pressing {{button|wii|A}}. All four team members can do this in a single race. When the player approaches another player, the one receiving the baton will start running. During their start, the baton is passed from one player to the other. However, if the player does not swing the Wii Remote down, it is passed automatically, but with a speed drop. When the player approaches the finish line, they can press {{button|wii|B}} to lead with their chest which also provides a small speed boost. [[Toad]] and [[Espio]] appear as referees in this event and alternate between being at the start and end of the running track.
