Bolt will need to be nothing short of his best to win, a prospect he has never been faced with before. We could very well see some world records broken in Beijing, as well as returning to the classic era when a victory was taken by a hundredth of a second, not a metre. But who will be the one crossing that lines first. For once, that is very much open to debate.
This week an Usain Bolt film has been announced, made by the men behind Class Of '92, Ben and Gabe Turner at Fulwell 73. The film will follow Usain as he heads towards the Rio Olympics next year and his retirement season in 2017. The story line above could well be what we see played out in this movie.
After Bolt's experience in Glasgow he might well decide it's just not worth risking a casual chat with a journalist, or even making a joke for fear it be twisted. If that were to happen he will become what every sports journalist loathes: someone who trots out the same, safe, coached clichés which offer neither insight nor entertainment.
Here I go... I'm Conrad Williams, British 400m and 4x400m track & field athlete. As a late bloomer I started athletics at the age of 20. Before that I was just playing a bit of football and basketball, until one day walking through the park I saw the running track in my local area of Lewisham. It wasn't long until I joined my local club, Kent AC.
