Men's pole vault final
We're hanging on for one final world record attempt from Armand Duplantis.
Can he produce fireworks and bring the first day of the World Athletics Ultimate Championship to a close in style?
Don't go anywhere...
Men's 5,000m final
Fingers crossed Jakob Ingebrigtsen is good to go in the 1500m final on Sunday too. Everybody wants to see that showdown with Josh Kerr, but he'll obviously need to be careful as he continues his return from injury.
Men's 5,000m final
Jakob Ingebrigtsen speaking to BBC Sport after winning the men's 5,000m.
"It's amazing. I haven't had that big of a season. Not too many weeks ago, I agreed with my team that 2026 was far gone, but then it started to get a bit better, and there was a lot of hope.
"I just tried to do as good as I could each day, eventualy I got momentum going and I think I've had a lot to gain from the races I've had.
"I felt strong today, but still the 5,000m level this year has been through the roof. I'm extremely happy that I managed to get sub-13, I think I've only done it once before, so that's amazing.
"For me the physical ability to be able to run that fast is a great thing for me going into the next races and through the winter. You fear the worst, the worst case scenario am I able to run again at all at this level, so it's truly amazing."
While we wait for Mondo to recharge, let's get some reaction to the night's events.
Men's pole vault final
Not to be at the first attempt for Armand Duplantis at 6.32m.
A couple more to come, if he's up for it.

Jaz Sawyers, simply a fabulous person. Brilliant personality and shown such grit to fight back after so many injuries. Brilliant at commentating as well. With Molly Caudery out at the moment Jaz is clearly G.B's top field event competitor

Men's pole vault final
Now it's just Armand Duplantis and a world record height.
The whole stadium is fixed on him.
Just how he likes it. This is his stage. His song is even playing in the background.
Men's 110m hurdles final
A photo finish will be required to settle this one!
Cordell Tinch is certain he's won it. But no!
World record holder Ja'Kobe Tharp just pips him on the line. He can't believe that, he thought he'd left it too late.
The 20-year-old takes the crown in 12.94 seconds, with Tinch recorded at 12.95.
Men's 110m hurdles final
One last final to come on the track tonight and it's the men's 110m hurdles.
American 20-year-old world record holder Ja'Kobe Tharp will start as favourite in this one.
There are five Americans in this eight-man final.
Men's pole vault final
Emmanouil Karalis can't respond!
Another failure at 6.20m and the Ultimate title goes to Armand Duplantis.
The Swedish star has looked in superb form this evening. Surely a world record attempt is on the cards from here!

The Ultimate trophy goes to an emotional Larissa Iapichino. As the Italian is embraced by her fellow athletes by the sandpit, the cameras catch her telling them that she lost her Grandma this morning.
How well she has done to hold herself together and get the win tonight. The trophy and $150,000 are hers.

Athletes put blood sweat and tears into their careers, only to miss a big event due to injury or other circumstances. For them to earn more money and compete more in, all for it.

Women's long jump final
Here goes Jazmin Sawyers. 6.90m needed...
Oh it's HUGE!
What a sensational end to her season. A final leap of 6.78m is not enough for the win, but it means she finishes second at the end of a summer which also brought European and Commonwealth medals.
She only returned to competition last year after rupturing her Achilles on her take-off leg. What a comeback!

That looked effortless!
Armand Duplantis celebrates with the crowd after continuing his perfect card at 6.20m.
Can Emmanouil Karalis match his personal best to keep this competition going? The crowd will certainly hope so.

Jazmin Sawyers has put herself in contention for the title!
The Briton is through to the final four and has one last attempt to try and out-do Larissa Iapichino's leading 6.90m-jump.
A best of 6.59m so far for Sawyers.
This would be so special following the long road back from injury she has endured.
Men's pole vault final
Mondo Duplantis goes clear over 6.15m at the first attempt too!
Game on.

What an effort this is from Emmanouil Karalis.
The Greek must have taken a decent hit when he missed the landing mat earlier in the session, but he has since cleared 6.05m at the final attempt to keep the competition alive - and then raise the bar for Armand Duplantis to 6.15m at the first attempt.
Duplantis has another huge battle on his hands here.
Women's 100m hurdles final
We were treated to a spectacular conclusion to the regular Diamond League season in Zurich last month, with two world records falling in quick succession.
Not long after Alison dos Santos clocked a stunning 45.80 seconds in the men’s 400m hurdles, American Masai Russell ran 12.09 for the women’s 100m hurdles.
It's not quite as fast this evening from Russell, but it's enough to take the Ultimate title!
She wins in 12.22 seconds ahead of former record holder Tobi Amusan.

Women's long jump final
Over in the women's long jump, Jazmin Sawyers failed with her first attempt and needs to produce something on her second to stay in the competition...
The European and Commonwealth medallist stays alive with a 6.59m jump!
Italy's Larissa Iapichino leads with a best leap of 6.90m.

Keely Hodgkinson has been speaking to BBC Sport after her 800m semi-final win.
On Veronica Vancardo's fall: "This season we've had a fair share of people falling over, but she's still got all her teeth so she'll be ok.
"That's one of my worst nightmares, touchwood it hasn't happened to me so far. It's part of racing unfortunately."
On her race: "I'm happy with that, I'm glad to be back running. It was a lot of fun.
"It's been a month since I last raced so it's nice to get that run out through the legs, hopefully go a bit better tomorrow."
