When you go into a world championships it can get very tense, very hostile, but at the same time I've got to remember why I started it, and that was just because I loved racing. I love winning and I don't want to take that fun out of it.

Athletes are always entitled to freedom of speech and when we detect that something is wrong and there's cheating, then why shouldn't we have a voice? any doping in the sport is a straight no from me.
