The true but rare runner's high is a zone that we enter when everything seems to click perfectly, when time stands still, and when we can run almost without effort.

Don't get discouraged. As far as I'm concerned, a positive attitude is the most important attribute any runner can have. You'll need it often. Every runner has bad days, every runner has occasional injuries, and every runner eventually slows down (take it from someone who has slowed down a lot). But as long as you maintain a positive attitude, you'll find ways to overcome the obstacles and continue running. After all, running offers countless rewards. It's simply up to you to find the ones that have the most meaning for you.

Best wishes for a great marathon. Be sure to savor it. The first marathon is something special. Run long and healthy.

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.

Winning is not about headlines and hardware [medals]. It's only about attitude. A winner is a person who goes out today and every day and attempts to be the best runner and best person he can be. Winning is about struggle and effort and optimism, and never, ever, ever giving up.

I like to say, and I truly believe, that every run brings new experiences. You just don't know what they might be until you actually do the run. That's one of my major reasons for pushing out the front door as often as I do-the adventure of it all.

It's wrong to believe that you need a certain physical body type to run. All body types can run. It's not about your legs, muscles, or cellulite. It's not about the physical side of things. If you train your brain, your body will follow. It's that simple. The hard part isn't getting your body in shape. The hard part is getting your mind in shape.
