That was absolutely remarkable.

The entire race the men were still in a massive group, with eight men a realistic chance of winning still.

And yet it was probably the ninth man in that group, Jimmy Gressier of France who came from absolutely nowhere in the home straight to win gold! What a finish!

Yomif Kejelcha claimed silver for Ethiopia with Andreas Almgren earning the bronze for Sweden.

The top six were separated by less than a second.

What a race.

My goodness.

Interesting.

That second semifinal was so physical that the Italian Marta Zenoni has been disqualified, according to our timing screens.

I can't imagine why they singled her out... But perhaps it's worth re-posting this photo...

Nele Weße has been reinstated for the final, while Sarah Healy of Ireland has snuck in as well.

Jess Hull has been speaking to David Mark in Tokyo.

She paid credit to her gym work for keeping her strong when the race is as physical as that - but she is also more than capable of dealing with the rough and tumble of a middle distance race. 

"I think, just with experience, you just become a little bit more conscious of, OK, it's going to be pushy, it's 1,500, we're all trying to run for the same position," she says.

"Especially when there's spots in the final on the line.

"Women know that tonight is their final and they run it like it's everything for them, so you'd just better be a little bit more aware in these rounds. 

"And I think I've just faced everything I could possibly in terms of different styles of races now in my career that I've just got to roll with what's coming at me."

Here is Linden Hall, speaking to David Mark with ABC Sport in Tokyo.

"I probably 90 per cent ran it to plan," she says.

"I tried to make a big move 600 out. But Faith was not one to give up the lead easy ... she wanted to stay at the front and I think I wasted a lot of energy trying to make that move and get past her.

"I would have liked some of that energy in the last 50 metres were I just didn't quite have the response when the girls came up.

"150, 100 to go I thought we were chilling, and then all of a sudden I wasn't and it was over."

Tellingly, she admits that it was probably a tactical error that cost her.

"I'm a bit mad at myself," she says.

"The last few months have been really great for me ... to fall just short is really disappointing."

In a brutally physical race, Jess Hull has made it through to the 1,500m final.

It was such a slow race that there were so many problems.

"That was like dodgem cars," says Bruce McAvaney on SBS.

He's not wrong.

With two laps to go there was a very solid shove that saw Nele Weßel almost lose her footing and Hull was so lucky to avoid that.

There were a couple of other issues too.

Nelly Chepchirchir wins, Hull second, Nikki Hiltz third, with Klaudia Kazimierska, Gabriela Debues-Stafford and Marta Zenoni the other qualifiers.

Oh that's a huge blow for Linden Hall.

She did everything so well, pushing the pace on the outside but has been swamped down the home straight.

Freweyni Hailu fell inside the first lap! It's so tight and that could have been a disaster for plenty of athletes.

Hall shadowed Faith Kipyegon through the opening half of the race.

The Aussie and the Kenyan ran side by side with a third of the race distance to go.

Hall pushed the pace and keeping that pace high, just pushing the superstar as they hit the bell.

Dorcus Ewoi moved into second ahead of Hall as they travelled down the back straight for the last time.

And Ewoi gets second behind Kipyegon, Hailu recovers from her fall to finish third, then it's Sinclaire Johnson of the USA, Marta Pérez of Spain and the Frenchwoman Sarah Madeleine.

Hall is seventh and will miss the final.

Linden Hall is in action in this first semifinal.

She will be up against Faith Kipyegon, among others.

A big test.

Gift Leotlela false starts the third semifinal!

The 27-year-old South African had a faster reaction time than is allowed.

However, it's Andre De Grasse who is given a warning for being unstable on the blocks.

We'll try again.

Oblique Seville has a great run, looking across the line from the outside lane at his rivals. It's 9.86! That's solid!

The posturing is so elite in these situations. You've got to love it. The mind games. The mental disintegration that needs to take place in order to get every little advantage.

Letsile Tebogo comes in second place in 9.94, with Leotlela sneaking in third in 9.97 to take a spot in the final.

That's really good news for Yual Reath.

He jumped his equal season's best of 2.25 at the second attempt to reach the final.

Kenny Bednarek and Kishane Thompson have dead-heated that semifinal at 9.85!

A good run, they both looked at each other there as they ran over the line.

Zharnel Hughes and Jerome Blake also dead heated with 10.03.

That is a dead heat down to the thousandth of a second too.
