The dynamic has really changed in the U.S. Americans believe they can be competitive, that they can win medals.

I'm interested in Dathan Ritzenhein's future in the marathon, and I believe that's where we need to address some issues he seems to have. He's had good marathon coaches - both Brad Hudson and me. He's figured out the fueling. He's got this incredible aerobic engine. But something's still wrong.

Early in my career I was accused of being overconfident and even cocky, but I really was confident that I had done the training and didn't see any other reason to say otherwise.

I think in running, to be honest, that even though athletes are very dedicated and are willing to train and do whatever they need to do to prepare, more often than not they're not in a very professional environment where you've got a high performance director and a coach that are really monitoring your daily activities.

I am still competitive and I still want to win,

I want to win medals for myself.
