Hills are speedwork in disguise.

Right now, after having had back surgery, I am finally back to running again.

I plan to be running as long as I can and have no plans to stop.

Yes, winning the gold medal was undoubtedly the biggest day of my career - mostly because I won the way I had prepared to run it. It was a totally satisfying experience.

You have to know your body. It's part of the beauty of the training process, and once you've determined how much your body and mind can take, you can then begin to reach your potential.

I think it is that parents just don't kick their kids out the door as much as they used to. I think the demise of sandlot sports has had a lot to do with it.

As I've been able to once again gain the benefits of speed work, I'm enjoying my running more and more.
