We run when we're scared, we run when we're ecstatic, we run away from our problems and run around for a good time.

Running should be free, man.

Running is the heart of what it means to be human.

We've got a motto here-you're tougher than you think you are, and you can do more than you think you can.

Everyone is built for running.

We are the biggest sissies in the jungle. Every other animal is stronger than we are - they have fangs, they have claws, they have nimbleness, they have speed. We think Usain Bolt is fast - Usain Bolt can get his ass kicked by a squirrel.

The only way to truly conquer something, as every great philosopher and geneticist will tell you, is to love it.
