Running on empty?

In the movie Chariots of Fire, there are 2 runners. Harold Abrahams who says that he runs to ‘justify [his] whole existence’ where as Eric Liddell says that he runs because when he runs he feels God’s pleasure.

Why do we run?

Are we on the run to justify our existence? Do we run for acceptance? To make more money? For power? For status? Or do we run to feel His pleasure? How might this running transform our lives?
