I want to be one of the greatest athletes ever to live, not only in track and field, but in all of general sport.

If I can stay [involved] with the sport, we can find different ways to motivate people and preach to them and explain to them that all they need is dedication to the sport.

I think the sport needs the help to continue to motivate athletes.

I've worked hard over the years, I've been injured and I've worked hard through it, and I've made it.

You have good days and bad days.

People always say I'm a legend, but I'm not. Not until I've defended my Olympic titles. That's when I've decided I'll be a legend.

Surprisingly, maybe the place I get recognised the least is the United States. America is not so big on track and field. Some recognise me there but lots don't.
