If you can travel faster than the speed of light, it doesn\'t matter how long you can run before you have to stop because in any time greater than zero you will be across the galaxy, and anything you touch will be launched in the opposite direction at an enormous velocity. The earth (if you were on it, and traveling at exactly the speed of light) itself, assuming you were about .75 kilograms would move backwards at a velocity of 3x10 to the -16 meters per second with each step you made. This isn\'t that much, but then you factor in the fact that you make over infinity steps in the couple second period of time, the earth would shoot backwards (or the stalactite would wrip right off the cave roof) at infinite speed. So, I don\'t recommend you move faster than the speed of light.
