100m Freestyle

100m Freestyle is a real-life olympic event that can be played in Mario & Sonic at the Olympic Games. It is under the "Aquatics" category, along with 4x100m Freestyle, and plays very similar to the 100m event in "Athletics". The goal of the game is swim two lengths of the pool first. The event relies on both Speed and Stamina.

Wii Version
The controls of the game are very similar to that of the 100m Dash event. The Wii Remote can be used on its own, or with the Nunchuk. Before the event starts, the player is given a certain swimming style (example, Vector has the Crocodile paddle). The way to swim is to steadily move the Remote and Nunchuk back and forth in a certain direction (e.g. Crocodile paddle is Left and right). There are five swimming styles.
 * Crawl – Forward and back alternately.
 * Breaststroke – Left to right alternately.
 * Butterfly – Up and down together.
 * Dog paddle/Underwater running – Up and down alternately.
 * Crocodile paddle – Left to right together.

When the event starts, the player has to hold while READY appears on the screen, to build up energy. When GO appears, the player has to release and flick the Wii Remote down, to get a speed boost. The sooner this is done, the better the boost, but doing it before GO appears will result in a Foul, and will slow down the player, rather than speed him/her up. Once in the water, the player has to use one of the above swimming styles, which will be shown when the player starts swimming. The faster the controllers are shaken, the faster the player will swim. However, more energy is used up the faster the player swims, and if all of the players energy is burned up, they will stop in one spot, and waste time. To combat this, the player has to press before the Stamina meter drops to zero. Perfect timing will give the player more speed, but bad timing will slow him/her down.

DS Version
The event is the same in the DS version of the game. Controls however are different. Instead of shaking the Wii Remote (and/or nunchuk) different ways of rubbing the touch screen make the character swim in their specific style. The beginning speed boost is controlled by pressing down with the stylus on the screen and releasing it when the event begins.

Description
''Dive in on the start signal and swim two lengths of the pool in the fastest time to win. Don’t forget to breathe, or it will cost you valuable seconds in recovery time!''

Trivia

 * Sonic wears a life jacket in this event, a reference to his inability to swim.
 * Vector is the only swimmer to use the Crocodile paddle, most likely due to the fact that he is a crocodile.
