1500m

1500m is an Athletics Event that exclusively appears in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games. The aim of the event is to be the first to reach in the finish line in the fastest time by using the panels on the ground and repeatedly pressing the Dash button. The starting World Record for this event is 3:26:00, while the starting Olympic Record is 3:32:07.

Gameplay
The event starts at the last 400m at 2:40, and tells the player the first set of controls, with one button for dash and a button each for left and right. The player must repeatedly tap the dash button to increase and maintain their character's speed, which will drop if they stop pressing the button, and use the left and right buttons to change lanes to move to the ones with panels in. The panels boost the character's speed for a short period of time, however the character must be mostly in the lane for the effect to work. Every 100m, the controls change, meaning that one or more of the previous buttons swaps to another control, for example the dash button may change from A to X.

Controls
1) Dash & 2) Move sideways: A/B/X/Y Button and up/down/left/right on +Control Pad. Run over the panels for a boost!
