Have you checked your key mapping, yet? In the character selection screen there is an Option button. On the following panel select Configure Keyboard... in the Controls section.

The entry Sprint can be found at the bottom of the right column. In standard configuration you have two possibilities:

1) V (with FPS and RPG)
2) X (with MMO)

However, you can assign this key as you see fit.

Ingame you might already have a Sprint icon in your quickbar. If not you can drag the Sprint button from the command menu while holding the Shift key. If the command menu is not displayed you can enable it on the Attributes page (standard keys: P, O, or Ctrl+T - according to your key mapping).

To start running either press the correct key or use the icon in the quickbar.
