Two-time European champion Sergey Subenkov is the world number one and is in absolutely blistering form.

The Russian clocked 12.92 - a new personal best - in Hungary last month. It was one of three sub 13-second trips this year.

No one else has been broken that barrier globally in 2018.

Good luck to the rest in this first semi-finals. France's Aurel Manga and Germany's Gregor Traber will lead the chase.

Kat's had a great day so far today.

Coming away from the javelin with a smile is incredible for KJT.

It's also a huge relief for Kat to put a 6.44 out there on the long jump straight away.

I saw Thiam do what she has done with that javelin in Rio, and that was with a strapped up arm.

She is an incredible thrower and we'll have to see what happens in the 800m.

Here are some of the highlights from the morning session of the heptathlon as Katarina Johnson-Thompson extended her lead in the long jump...

...then launch a personal best in the javelin as Nafi Thiam struggled in her first two throws....

...but Thiam produced an extraordinary final effort of 57.91m to swing things on their head and give her a lead worth around 13 seconds heading into tonight's final 800m.

KJT joined the sporting applause, but I think her face told the real story.

Triathlon winner Pierre Le Corre speaking to BBC Sport: "I feel really great. It was really tough today with Alistair Brownlee. I was scared of him because he is an opponent that is hard to beat but today it is my day and I'm really happy.

"I was scared of Alistair - but he's not in shape right now, I could see it but he will be back for sure."

Britain's Barclay Izzard, 20, speaking to BBC Sport after finishing ninth in the triathlon: "I came into this race for experience, I sat in there on the bike as knew Alistair Brownlee was up there so there was no point helping the rest to chase him down. Then I tried to race the run and I'm super happy with that.

"This race was mainly for experience and to come in the top 10 is surreal. I didn't expect to do that. I had a foot injury for six weeks so I've not run much - so to do that with minimal running, I'm real happy with that."

There is so much athletics goodness on offer tonight in Berlin that BBC Two crew stretched the programme over two on-screen graphics.

The highlights from a British perspective include Katarina Johnson-Thompson in the heptathlon, Matthew Hudson-Smith in the 400m, Dina Asher-Smith in the 200m semi-finals and Morgan Lake in the high jump.

Mark your cards.

Alistair Brownlee speaking to BBC Sport after finishing fourth in the triathlon: "I knew I was going to struggle on the run as I've not done enough sessions yet, but I enjoy racing.

"The swim was really hard, I got really beaten up at the start but that's all part of it. On the bike I got a group working but I couldn't really do anything on the run."

On not having his brother Jonathan to work with: "Most of the guys wanted to ride, they just don't know how to make a group go faster so some of them just get in the way. But it was a hard course and it was difficult to get a group moving on it.

On his preparations: "I have had a terrible six months. I've literally had a handful of run sessions and so off that I can be quite pleased. I'm just happy to be racing.

"I didn't really know what to expect, I've been training hard and so I knew I was going to be tired going into it."

Here's the medal table heading into the nine athletics finals in Berlin.

Can Great Britain close the gap on Russia?

Here's the winning moment from the triathlon.

Great Britain's Marc Austin - hampered by a heavy fall on the bike - has battled home five minutes and 34 seconds behind the leaders in 35th place.

Great Britain's Barclay Izzard finishes in a very creditable ninth, two minutes and two seconds off the pace.

Scotland's Marc Austin is still out there after a heavy crash on the bike stage, fighting for a finish on home turf.

Alistair Brownlee finishes 55 seconds behind winner Pierre Le Corre and in fourth behind Fernando Alarza and Marten van Riel.

The trademark searing run stage is not quite there yet after a lack of race practice.

Fernando Alarza gobbles up Marten van Riel like an orca swallowing a seal.

He is up into silver. He has Pierre Le Corre to aim at. Can he overhaul him?

Marten van Riel of Belgium is still ahead of Fernando Alarza in the second.

But the Spaniard - just out of shot in the picture above - is breathing down his neck.

Leader Pierre Le Corre is grimacing and gurning with effort.

Who's your pick?

France's Pierre Le Corre has left Belgium's Marten van Riel behind.

He has upped the pace to try and stave off the threat of the fast-closing Fernando Alarza.

it is boiling up into a tremendous finish. It won't involve Alistair Brownlee though.

The good thing about Brownlee is he looks sound and he doesn't look injured.

I just think this is all about lack of races this season.

He is definitely on his way back to the form we would like to see him.

That gold medal is under threat with Alarza's pace.

I'm not sure there's a lot the two leaders can do to stop him.

He's just finding form in this race it appears.

Fernando Alarza breezes by Alistair Brownlee and barely breaks stride.

The Spaniard has his eyes on gold.

Twenty-two seconds separate him from the leading pair of Pierre Le Corre and Marten van Riel.
