I have learned that there is no failure in running, or in life, as long as you keep moving.

I always tell beginning runners: Train your brain first. It's much more important than your heart or legs.

Everyone stumbles at one time or another. It's the human condition

We have all learned everything we know physically—from walking to running a marathon—by trial and error, so there's no reason to become our own worst enemies when we suffer a setback. From time to time everyone falls short of their goals. It's an illusion to believe that champions succeed because they do everything perfectly. You can be certain that every archer who hits the bull's-eye has also missed the bull's-eye a thousand times while learning the skill.

You have to want it, you have to plan for it, you have to fit it into a busy day, you have to be mentally tough, you have to use others to help you. The hard part isn't getting your body in shape. The hard part is getting your mind in shape.

Success does not come to the most righteous and rigorously disciplined but to those who continue running.

This wasn’t just an attack against the Boston Marathon... It was an attack against the American public and our democratic use of the streets. We have used our public roadways for annual parades, protest marches, presidential inaugurations, marathons, and all manner of other events. The roads belong to us, and their use represents an important part of our free and democratic tradition.
