Sprint

Sprinting is a feature introduced in GTA III and is continued furtherwards except GTA: Chinatown Wars. Sprinting allows the players to run faster, in order to sprint on Playstation, X must be held down, Xbox requires A to be held and on PC, Left or Right Shift is usually used. If sprinting for a certain amount, the player will tire out so sprinting will be canceled out and if not moving, he will show his exhaustion. On GTA IV, Lost and Damned and The Ballad of Gay Tony, Sprinting allows the player to run faster and even though it seems like that it's unlimited. But if you keep Sprinting for a while, you will see that the game won't allow anymore sprinting, but if you stop moving, you will see that the player won't show his exhaustion.
