I only really care about the sprint events - 100m, 200m, and 4 x 100m relay.
Long jump, high jump & triple jump are also interests of mine.
I want Usain Bolt to retain his 100m, 200m & 4 x 100m Golds.
The 100m is my main even in athletics though, so it's the one I'm most interested in.
Yohan Blake has the psychological edge at the mo after the Jamaican trials and the World Leading 100m time, but if Bolt runs confidently, he can break his own World Record.
I hope he gets a 9.4 , think he'll get a 9.48 or 9.49 IF he maintains his training and focus.
Think the Jamaican men will get Golds in all 3 sprint events.
Shall be a good watch!
