Go to the city of Whiterun. Move through the town until you reach Dragonsreach, which is the castle. While standing on the steps looking at the doors to Dragonsreach, look to your right. There should be a building that resembles a ship's hull. This is where the Companions are located. Go and join them. After a few quests you are given the chance to become a werewolf. To use your new ability, go to "Magic", then "Powers", then "Beast Form". Beast Form can be used once a day. You will turn into a werewolf and friendly humans will attack you. You will have increased speed, health, damage, and stamina. You cannot pick up objects. If you kill a human you can "Feed" on the corpse to regain some health and extend the duration of Beast Form. This is also useful for traveling great distances on foot. When the werewolf sprints, it runs on all fours, and moves much faster than a horse. The werewolf's stamina also regenerates very quickly.
