Sprinting

Sprinting is a feature in Beta 1.8, which allows the player to run two times faster than walking. The player sprints by double tapping (default) and then holding it. It will be possible to jump across four blocks horizontally (instead of the usual two blocks) by sprinting, however the jump will be no higher than normal.

Sprinting is unlimited so long as the Food Bar is above 30%, but will also drain the bar slowly. When a player sprints, particles will come from the player's feet. When a player hits any passive animal (excluding squid), the animal will start sprinting away from the player.

If you hit a mob while sprinting, the mob will fly back.

Sprinting stops when you run into a block or parry with a sword. You do not stop sprinting when you run into a mob. Also, the player will not be ignited when you run through up to four consecutive blocks of fire (the fifth block will ignite the player).

If you turn the FOV to the max and sprint, when you look down, it seems as the player is above ground.
