Suffering is an extraordinary teacher.

It takes faith and the courage to risk failure in order to realize one's destiny. Having had my share of failures throughout my career I know that it is well worth the risk.

You dream about the Olympics for so long and you have that one day, then it's over, and when you don't run well there is this huge letdown. It took me years to deal with that. I feel like I almost had to cleanse myself of that experience.

I may not drink an electrolyte beverage during the race. If I am running in an hour, I won't need one. But if you're running an hour-and-a-half to two hours or more, maybe you need a little bit of the electrolytes.

It took years, honestly, to deal with the disappointment of Beijing.

I don't think about the miles that are coming down the road, I don't think about the mile I'm on right now, I don't think about the miles I've already covered. I think about what I'm doing right now, just being lost in the moment.

It's a long, hard road and it's going to have its bumps; there are going to be times when you fall and times when you don't feel like going on anymore, times when you're just crazy tired but it takes focusing on that one step you're taking. That's what I'm trying to do with the marathon; I don't think about the miles that are coming down the road, I don't think about the mile I'm on right now, I don't think about the miles I've already covered. I think about what I'm doing right now, just being lost in the moment.
