When running, you move five times your normal speed (if wearing medium, light, or no armor and carrying no more than a medium load) or four times your speed (if wearing heavy armor or carrying a heavy load). If you make a jump after a running start (see the Acrobatics skill description), you gain a +4 bonus on your Acrobatics check. While running, you retain your Dexterity bonus to your Armor Class.
