I have the PC version of Skyrim. I tapped the sprint button ( B ), and sprinted until my fatigue was empty, then I tapped B again and the sprint continued, but my weapons moved to the normal position they are in while at regular speed. I tested this again and it worked. I restarted the game, and it still worked. Am I supposed to have unlimited sprint, even after my fatigue has gone down completely? Has anyone else noticed this?
