I have had enough rest and enough training.

I don't want to leave the sport saying I could have run faster. I just want to be tapped out, like I gave it my all.

People mistakenly believe that if you do nothing but train you can only get better. You've got to work hard, but the harder you work the harder you must rest and relax.

Double gold means I'm king of the sprints. It shows I'm the best sprinter around.

I ran like a champion. It is a great consolation to show how dominant I am. I am the Olympic champion and the world champion, but I want Justin Gatlin to be the champion of everything.

I have had enough rest and enough training.

I look at myself as the 'Batman' of track -- a vigilante. You may not like me, but I'm needed.
