Usain Bolt Vs Yohan Blake
That Usain Bolt is the world's fastest man used to be a no-brainer. But now he has been beaten in both the 100m and 200m events by fellow Jamaican Yohan Blake, at the Olympic trials. Don't be surprised if Bolt looks over his shoulder in London.
For world records, instead of Badminton, I think it would be interesting to drop into the Weightlifting venue, where records may go tumbling with this year's competition. The former being a foregone conclusion to the powerhouses from Asia, I don't think there will be anything else short of a winning performance.
