Kneeling And Running
Kneeling and running means moving while kneeling (-2 Defense against melee attacks, +2 Defense against ranged). Running in this manner is awkward, and so turning costs 5 ft. (1 space) of movement. You cannot run full out while running in this manner without the Run feat (and even then, you only move three times base speed, not five times and it cannot be done in heavy armor.
