You'd like more people to recognise what you do is special. But I take the attitude that the best thing I can do for my sport is to be the best at it. The best way people will come to recognise that track and field is a great sport is to see athletes excelling at it. Which is what I intend to do.

You have got to believe in yourself every time you go out there and race. If you have no faith in your ability all that training has been a waste of time.

My stance has always been that there's no place in our sport for drug users. I've always said it's a ban for life if you come up positive. I stand by that.

In America, we have three major sports - baseball, football and basketball. They get the most coverage. Then there's things like golf which mop up most of what is left. But track and field? We are way at the bottom of the totem pole.

I've had bad jobs. Now I have a good one. I'm thankful.
