Catch them if you can.

IF you saw Usain Bolt smash the sprint world record at last year's Olympic Games, you'll already be aware that planet Earth is currently home to a man who could catch a bullet while wearing flip-flops and, quite possibly, carrying a wardrobe.

After all, he crossed the finish line so far in front of his competitors, he had time to slow down and wave his arms. The only way he could have looked any more at ease is if he pulled his mobile phone out of his leotard and took a picture of himself crossing the line.

But the blue riband event at this month's 12th IAAF World Championships, which starts on BBC2 at 10.30am, is by no means a onehorse race. It's the setting for one of the most eagerly anticipated battles in sport.

The triple Olympic champion, Bolt will be eager to show the world he is still the man to beat as the 100m heats get under way, but current 100m, 200m and 4 x 100m relay world champion Tyson Gay of the USA has been in fine early-season form and will be reluctant to give up any of his crowns without a fight.

The 100m final is at 8.35pm tomorrow.
