Now, to these Games, I'm happy again. In a way I was not from the period between 2007 and 2009, which was the best of my career

The 200m (world record) is definitely on the ‘to-do list’ for me, so I’m really focused on getting that done

I’m putting my body through hell every day to make sure I do myself proud in Rio

Rio is amazing, perfect for holding such a big event. The people’s passion and the beautiful locations will make the Games very special
