Is Usain on the right track?

He has totally dominated the 100m and 200m sprints over the last two years and no one on the planet is going to bet against him doing exactly the same in the smallest of the middle distances.

Traditionists would even argue that the rangy Bolt is actually designed for the distance, rather than the sprints he has dominated.

But Bolt seems to be someone who enjoys tearing up the rules and creating new ones.

There's no doubt he has the speed, it's just a question of stamina over that longer distance.

But when he looks round the wide curve of the track on February 13, a thought about Michael Jordan might flash across his mind.

Bolt's decision to expand his repertoire isn't the first time that a major global sports star has changed disciplines, and not anywhere near as dramatic.

Jordan, at the height of his powers, quit basketball and fulfilled a lifelong dream to play baseball for Minor League side Birmingham Barons.

It was a totally forgettable move and he quickly returned to basketball, where he went onto dominate the NBA for the next six years.

We'll wait and see whether Bolt further cements his place in history, or enjoys a minor distraction before going back to leaving his competitors in a trail of dust in the sprints.

The whole John Terry affair
It was tempting to write my blog about John Terry this week, as you can see I have failed in resisting the urge.

I'm not going to say much on the subject as the entire country seems to have held lengthy debate on the matter.

I couldn't give a fig if he remains England captain, but there is no way he's going to be dropped from the squad because he's a vital player for England.

Wayne Bridge's decision to boycott England only ends his hopes of adding more caps.

No one seems bothered that he's betrayed his wife, more that he's broke some unwritten ethical code by sleeping with a teammate's partner.

John Terry is a cheat, that's a fact, being England captain is totally unrelated, no matter who he's slept with.
