People say who is next? Who is next for what? Who's going to fill the void as the best or the most track and field athlete? Someone will always fill that role but no one is going to be the new Usain Bolt and have that presence outside this sport.

You have to be unique. Usain has brought people into the sport who wouldn't be here. You have to transcend the sport in order to do that and be your own brand. He is extremely unique as an athlete and a person and that doesn't just automatically happen.

Let's see how this goes.

Usain Bolt is on the scene.

The Jamaican showman has been twerking around the warm-up track, plugged into his own tunes, oblivious to the star-struck fellow athletes who are attempting and failing not to stare at the ringmaster.

Bolt appears in the 100m heats at 20:20 BST.

The weather is pleasant now but it was very wet in the days leading up the Championships as some of the international athletes were welcomed to a traditional British summer!

London 2012 Olympic heptathlon champion on BBC TV

It's a very strange situation to get a medal like this. I am grateful to receive my medal here in London on Sunday, but those moments of celebration are taken away from you at the time.

Thankfully I was able to go and win more medals, but for some it was their only chance to win a medal and be in the limelight.

Usain Bolt has only raced three times over 100m this year but he clocked 9.95 seconds to win the 100m in Monaco last month.

Has he still got the power in his legs to hold off his rivals?

We'll have a better idea when we see the 100m preliminaries at 19:00 and the first round at 20:20.

The semi-finals and final are on Saturday.
