Matthew Carter: I remember seeing Ayana doing this for the first time. Still blows my mind the gap she pulls out. Different level

Brendan Foster
Olympic medallist and BBC commentator on BBC One

"We have never seen anybody destroy a field as Ayana has done here. You look at that time and you wonder 'can she keep going at this pace?'"

Steve Cram adds: "I think she is going for a new world record which is the most number of athletes lapped."

If Almaz Ayana can maintain this pace, this will be the most jaw-dropping performance of the championship no matter what happens for the rest of the week.

She has obliterated a top-class field. She is more than 200m ahead of a chasing pack that includes the legendary Tirunesh Dibaba.

Fiona Lapham: The lead Ayana has is absolutely insane! Absolute doff my cap to distance runners, I'd struggle to do a lap!

The United States Jarrion Lawson closes the gap on leader Luvo Manyonga with an 8.47m.

That is just a centimetre off the South African, but an inch is as good as a metre in the long jump.

"I thought the thee Kenyans may give Ayana a race for her money tonight but she's way, way out on her own."

Brendan Foster adds: "Remember she did something similar in Rio and did come back. But at the moment she is absolutely destroying this field."

Bryan: Great form from Ayana in the 10000m; long, easy, fluid strides...

We have not seen her all year but Almaz Ayana has emerged for the first time in 2017 and looks in the same sizzling form that shredded record books in Rio.

The Ethiopian throws a dizzying 2:49 kilometre into the midpoint of the race and the rest of the pack have nothing in response.

The Olympic champion has a 40m advantage.

Ayana is faster over the last 3km than most of these girls are capable of. It is no wonder they are not tried to go with her. Dibaba never reacted. She knew what the plan was and what Ayana was going to do.

Luvo Manyonga goes big in the second round in the long jump.

The white flag flies north and we await the digits.

Here they come...

8.48m takes the lead!

London 2012 Olympic champion Greg Rutherford misses the long-jump with injury of course but is watching as the athletes begin the final.

He tells BBC Sport he will return to the sport soon and will take the indoor season seriously in his bid to get back to winning titles.

"I'm going to take the indoors seriously for once," he says. "That might sound strange but normally I compete in summer and train all winter. I'm going to go for it at the World Indoor Championships. I've held all four major outdoor titles. I don't have the world indoor or European indoor, they are coming over he next two years.

"If I can win those two, there is nothing I haven't won in the sport."

Rutherford, 30, says he may use the Glasgow Indoor Grand Prix as a warm-up for the world indoors which will be held in Birmingham.

If Usain Bolt and Christian Coleman are playing out the establishment v iconoclast narrative in the 100m, there is something similar going on in the discus.

Poland's Piotr Malachowski is the world champion,but Sweden's Daniel Stahl is threatening to rip up the ancien regime.

The 24-year-old Swedeproduced the farthest discus throw in the world for four years in June, frisbeeing his way out to 71.29m.

Three-time world champion Robert Harting - whose London 2012 gold-winning celebrations involved falling asleep on the train and getting locked out of the athletes village, external - will also hope to reassert his dominance after missing out on a medal two years ago.

The biggest shock on the opening day of competition came in the long jump pit where a shell-shocked Jeff Henderson failed to make it through qualifying.

The American Olympic champion's early exit may well leave the way clear for South Africa's Luvo Manyonga to take gold.

Manyonga - who took silver in Rio - has the four longest leaps of the season. But the fact that he is involved in top-levelsport at all is probably a bigger triumph than any he could pick up today.

After finishing fifth in the 2011 world championships as 20-year-old. Manyonga slipped into crystal meth addition on his return to his township neighbourhood.

He copped an 18-month ban for testing positive, but has fought his way back and shaken his demons.

No Greg Rutherford for Great Britain after an ankle injury knacked the 2012 champ. Instead the main threat to Manyonga is likely to come from his compatriot Ruswahl Samaai.

In all probability, they will be dancing on the streets of Addis Ababa this evening.

Ethoipia have turned the women's 10,000m final into pretty much a domestic championship such is their strength in depth.

Almaz Ayana has the pedigree with victory at Rio 2016 and the world record on her CV, but not the form. Shehas been injured for much of 2017 and this will be her first competitive race of the year.

Compatriot Tirunesh Dibaba, triple Olympic champion, was rumoured to be attempting the marathon but instead goes for a fourth 10,000m World Championships gold.

And just to cap it all off, Dera Dida is the fastest of any of the field this year.

British trio Jess Martin, Charlotte Taylor and Beth Potter have their work cut out.
