I always try to do better than I have before, so I think it would be good to break the world record.

My goal in Korea is to win. There's no timetable when to set the American record.

It's something special to break the world record at the Olympics.

An Olympic medal is much better than a world record, and so is a world championship or Commonwealth Games medal.

I'm probably a lot more closer in the 1500m to the world record than I am in the 5000m.

I think watching multi-events is much worse than competing. Especially when you have vested interests because you go through the emotional ups and downs.
