Women's high jump final
For those of you asking, we won't hear the Russian anthem for 'neutral' winner Maria Lasitskene. She'll get the IAAF anthem at her medal ceremony.
Sing along at home.

A bit late thanks to the Mo Farah appreciation lap, but the decathletes are away.
Kevin Mayer will win gold here unless something extraordinary happens.

Image source, ReutersThere are athletes out there who have won more medals, but the quality of those medals and for Mo to have led an event on his own... wow. I don't know how you can't see him as our greatest ever athlete.
At times, people have questioned things about him. He hasn't run crazy times, he has just been consistently able to perform against the world's best at big championships. Your legacy in this sport is always down to medals. Records are broken. Nobody ever remembers who had the record before it was broken.

Britain's Andrew Butchart, who finished eighth in the men's 5,000m, speaking with BBC Radio 5 live: "The race went as my coach said it would but I didn't react. They were too quick for me. I am happy with it. It was my first world champs final so I have to walk away pleased.
"I'm gutted for Mo, but he is the best in the world. Look at what he has done. He leaves a legend. I know he will be upset."

Olympic heptathlon gold medallist on BBC TVIt takes a little while to digest this.
He doesn't look happy right now and you can understand this. But when he goes home tonight, hopefully he can take a beat and say to himself, "yes I am great".
He has been very blessed to be able to finish his track career in this stadium in London. It's incredibly poetic.

There's a hug for London Mayor Sadiq Khan too as he completes his lap. What a pro, what a champion.
His retirement from the track leaves a gaping hole in British sport.

One more lap. Make it 301.
Mo Farah does a lap of honour, posing for pictures with his adoring public. Do they wish he had won gold? Of course they do.
Do they still love him? 100%.

Chief sports writer at London StadiumThe stadium stunned, the great champion dethroned at last. Like Usain Bolt, his partner in track hegemony, Mo Farah proves himself mortal after all. Time catches up with even the fastest men.

BBC athletics expert on Radio 5 live sports extraSince 2012, Mo Farah has been a machine. What he has learned to do is win. They have criticised him for not doing world records but that is ridiculous. Tonight he got beat by the better guy, who is 23 (Mo is 34).

What a great race. We have not seen Mo Farah dropped to the extent that the two Ethiopians managed at the start of that last lap. A decisive, clinical move.
