Unfortunately, I don't usually get to see much outside the Olympics as I compete almost every day. I have been to Rio a few times and got a tour of the sites. It is a spectacular city.

I am doing what I do [athletics] because the fans love it and it's a part of me, it's my personality. I think people come to see you run fast, but they also come to see a show, a performance. They want to see a personality, and that's what I give them.
