"One of the perks of the job of heading the IAAF is that Lord Coe can choose which medal ceremony he conducts, and he will take a lot of pride in hanging that gold medal around Mo Farah's neck."

As has become tradition at major championships in recent years God Save the Queen rings out for the 10,000m winner. Farah gazes at the Union flag which is being raised. There's no singing from the Briton. Energy must be preserved for the 5,000m heats, I suppose. 

It's a marvelous looking medal, a massive circumference, the sort of thing which could be used in a weight-lifting session. 

But let's stop chatting about the sprinters for the moment because a distance running great, Mo Farah, is ready to collect the 10,000m gold medal he won on Saturday night. 

Lord Coe, the president of the IAAF, is the man who will be hanging the precious metal around the Briton's neck. Lovely.

Bethan Rudge:  You have to give @JohnsonThompson, external credit, she wanted that Gold and probably missed out by 0.1cm! She'll be back.

Leon Mann: Gutted for KJT, + coach Mike Holmes, after she fails to register mark in long jump.

Little Frank:  Strange competition overall from KJT. Increased pressure from the return of Jess perhaps?

Jamie Goodenough: Way to go Martyn Rooney.

"On a scale of one to 10, right now I'm at a 12 looking forward to the men's 100m final later."

For those of you who have not heard, there's a little race happening this afternoon called the men's 100m. 

Good, so they say, will attempt to overcome bad. The man labelled as the saviour of the sport is set to come up against a two-time drug cheat. It's Usain Bolt versus Justin Gatlin and we simply cannot wait. 

The semi-finals will be at 12:10 BST with the final two hours later at 14:15. Exciting, isn't it.

You won a gold last night, you say? The fourth world title of your career, you say? Well done, but I don't suppose you could take this picture for us? Many thanks.

Other things happened during the unwelcome hours, such as the men's 400m heats which were super-fast.

Britain's captain Martyn Rooney produced a personal best of 44.45secs - the fastest time ever run by a Briton at a Worlds - to qualify, although the extraordinary level of competition meant that time was only enough to see him through as a fastest loser.

As 18 men went under 45 seconds, Rooney finished fourth in a heat won in 43.93secs by Yousef Masrahi, with British champion Rabah Yousef also through by virtue of winning heat five in 45.24secs.

Before we move on to other matters, I present you a table with names and numbers which make up the heptathlon standings as we go into the final event this afternoon. Peruse at your leisure.

As Gabby Logan points out in her tweet, you can watch heptathlon highlights, as well as live action, from 11:00 BST on this page - or on BBC2. 

It doesn't make for comfortable watching, but you can watch Johnson-Thompson's long jump heartbreak by clicking here. 

Officials spotted the tiniest scuff mark in the plasticine beyond the take-off board. Johnson-Thompson protested. There were three minutes of argument before officials decided her third effort would not be measured.

It was not how the day was supposed to unfold for the Briton who was second overall after day one.

What exactly happened overnight in the heptathlon? Why isn't Katarina Johnson-Thompson in contention anymore? I'll begin at the beginning... 

Johnson-Thompson, last year's world number one, fouled out of the long jump, ending her hopes of winning a first senior World medal [sigh].

The 22-year-old recorded no jumps in the first two of her three attempts, appeared to have rescued it with a huge leap in the third only for that also to have been ruled a foul too. 

No points from the fifth discipline effectively means no medals. She's now in 29th place.

"Jessica Ennis-Hill has one hand on heptathlon gold with just the 800m to go," says Tom Fordyce, our chief sports writer in Beijing. 

The final event of the heptathlon will be at 12:40 (BST) so we've only got under two hours to wait - and the Briton has a cushion of just under six seconds going into her final event.

That's even better than it sounds because Ennis-Hill's personal best is three and a half seconds faster than Netherlands' Nadine Broersen, who is second overall, and more than a second faster than that of Canada's Brianne Theisen-Eaton in third.

Hello! Welcome to the second day of the World Championships. What World Championships? The Athletics. Where? Beijing. And there's been good news while you were sleeping (if you were sleeping) because Olympic champion Jessica Ennis-Hill looks set to become a two-time world champion, which sounds rather splendid.
