The Sprint is a technique that appears in the Sonic Boom series. It is move where the user accelerates to high speeds.
When performing Sprint, the user starts running at noticeably higher speeds that they would not usually be able to reach otherwise. While moving at such speeds, the user leaves a color trail in their wake. The user will also automatically initiate the Sprint when utilizing Boost Pads. The Sprint is a vital move for clearing levels in record time.
Sonic Boom: Shattered Crystal
The Sprint made its first appearance in Sonic Boom: Shattered Crystal. In this game, the move's color trail depends on the character: Sonic's trail is blue, Tails' is yellow, Knuckles' is red and Sticks' is orange. To use Sprint in gameplay, the player has to press while moving; for as long as the user is moving on the ground and does not collide with a wall or takes damage after is pressed, Sprint will be used, even if is released.
Sonic Boom: Fire & Ice
In Sonic Boom: Fire & Ice, the Sprint is usable to Sonic, Tails, Knuckles, Sticks, Amy Rose, and the Bot Racers during Bot Racing. In this game, its color trail depends on whether Fire Mode or Ice Mode is active; in Fire Mode the trail is red and orange, and in Ice Mode it is blue and white. Like in Sonic Boom: Shattered Crystal, the player has to press while moving to use Sprint in gameplay; for as long as that button is held, Sprint will be used. The Mega Sprint upgrade also returns and can be bought from Tails in the Bot Racer Workshop for 700 Ragnium shards.
