Cheruiyot still at the front but Taoufik Makhloufi is pushing him on as they come around the final bend.

A big pack coming together at the front as the finish line approaches...

At 800m down, Cheruiyot is still setting the pace but Alexis Miellet is pushing him on.

Ingebrigtsen is on the Kenyan's inside with Neil Gourley in about seventh with one lap now to go.

They are tough rounds. It was great to see all the British boys run so well. I'd like to see them run the same tonight. The quality and calibre of the distance racers, they all have tough asks. There are no easy semis tonight.

Timothy Cheruiyoit is at the front of the pack in these early stages, with Craig Engels and Neil Gourley at his heels.

Kalle Berglund is also in the mix at the front, as is Filip Ingebrigtsen.

Let's get this show on the road.

We are under way.

I'm not sure how Filip Ingebrigtsen avoided being eliminated. The leg contact is arguably accidental. The punch isn't. you need a certain arrogance to win at that level, but you cannot believe you can do things and getting away with things that are outside the rules.

Filip was disqualified in Rio and again in the indoors. You have to be able to control that aggression and anger - it's fine if you channel it into racing. Nobody should be above the rules.

So first up, we've got the men's 1500m semi-finals.

There are two semi-finals taking place, with the first five in each qualifying for the final and then the next two fastest.

In semi-final numero uno, we've got three-time major championship silver medallist Timothy Cheruiyot in lane two, while former European champion Filip Ingebrigtsen (lane three) is also involved, having escaped disqualification for punching Ethiopia’s Teddese Lemi (who is also in this semi-final) in the back during Thursday’s heats.

British champion Neil Gourley (lane seven) is also in this one.

Where have you all been?!!

KJT will be in the studio with Gabby and co a little later on tonight, but before then, we've got plenty of action coming up.

That includes the men's and women's 4x100m relay heats, and British Athletics have named the quartet flying the flag for GB in the latter.

• Imani-Lara Lansiquot
• Ashleigh Nelson
• Daryll Neita

How brilliant are these photos?

This will delight Liverpool fan KJT. Reds boss Jurgen Klopp has had his say on her golden moment:

"I have to say congratulations, brilliant. I knew about her relationship to Liverpool before, I didn’t watch it last night but I saw it this morning first thing in the newspapers.

"It was really great, well done."

I don't know about you but if I was in that friendship group, I'd feel pretty inadequate...

If ever there was a good excuse to crack out the old school photos, winning a world title is probably it.

I think that's a no...

Tonight's action in Doha gets under way in around 25 minutes. Before then, let's rewind the clock to last night.

World Championship gold and a new British record. It was a night to remember for Katarina Johnson-Thompson.

There is a duty of care because of the spotlight athletes live their life under. I think it's really important for federations to help athletes understand that sport is what you do - it is not who you are.

It can be lonely - you have friends and family around you and they're typically not in the same space as you. It can be difficult to go to your teammate - someone who is handling [the pressure] well.

Sport is about being able to have that sense of perspective. Sometimes that can take time. You have to be able to make that distinction - this is sport and this is real life.

Like Tom says, it's about being able to be OK in your own skin, and being happy. Without a doubt after what Tom has been through, he's become a much stronger person.
