Bolt’s got another four or five years before he’s likely to be at his physical peak, so 9.4s is by no means an unrealistic target, but my one fear is that he may suffer from a lack of viable competition. The likes of Tyson Gay and Asafa Powell (himself a prodigy at one stage, though a completely different athlete since his ankle injury) aren’t going to get any quicker and there don’t appear to be many youngsters capable of laying up with the Jamaican.
If he isn’t pushed at some stage, will he keep improving?
I for one would love to see him (Bolt) take on the 400m. I know he hates the event, and that his speed over shorter distances marks him out as an effective non-stayer, but physically he’s perfect for it and could (if he trains correctly) annihilate Jackson and Wariner.
