Usain Bolt answered the press

When you’re on top of the world with records in your name and having four of the 10 quickest 100m times in history, and five of the 10 quickest time in 200m, well you’re abound to fuel suspicion.

Usain Bolt iterates he’s clean.

Usain Bolt, “I’ll continue running fast, I am clean without a doubt. As soon as you start running fast there’s going to be a problem. It’s going to take a couple of years for people to start believing that you’re actually clean.

If you continue running fast and doing it clean then over a period of time all the tainting will go away. People will continue to say it until that period of time. I’ve been saying this all season.

People always say things, athletics has been through a lot, but it’s changing, definitely. The IAAF is doing a very good job of cleaning up the sport.”
