No stopping Tom Walsh however, whose final throw is simply a lap of honour.

Walsh's opening throw of 21.65m could not be matched, a season best effort when it mattered. It seals gold, his 10th major championship medal.

The man from New Zealand tops a podium with Americans in second and third - silver to Roger Steen, bronze to Adrian Piperi.

Into the final round of throws, with just the top six men remaining in the competition.

American Roger Steen pulls out a mighty last-gasp effort, 21.62m to lift him into the silver medal spot.

Olympic champion Miltiadis Tentoglou has finally woken up just a little bit in this finall.

The Greek's fourth jump is his best so far, 8.14m to lift him to fifth.

He is 0.16m behind the leader, Mattia Furlani of Italy.

Britain's Georgia Hunter Bell speaking after her 1500m bronze: "1500m is like a riddle, it can go any way, and no-one knows until we start. The Ethiopians went off really fast from the start. Fair play to them for changing the tactics and keeping us guessing. I'm really happy.

"With training, I'm very in tune to what four-minute pace feels like. It started off very quick. I wanted to stay patient, bide my time and back that I'd be able to finish strong.

"The Europeans was the biggest loss in my career so far. I was so inspired by some of the performances on the team - what Amber did last night, I just saw Neil get his medal. I just wanted to contribute.

"It's a huge learning curve. My lowest finish ever in a Team GB vest has been fourth. I have to give myself a bit of grace, but there's a lot more to come.

"If I look back to where I was this time last year, I couldn't break 4:03 indoors. Here I've gone nearly four seconds quicker indoors, so hopefully that bodes well for the summer."

We've had the 1500m finals, now let's have the 800m medal races.

The men are up first, with USA's Josh Hoey the favourite. He's aiming to break the world record in this event, which has stood for 28 years.

Into the final two rounds of the shot put, and no-one has got close to the 21.65m set by Tom Walsh with his very first effort.

Gold looks to be heading to New Zealand unless someone can pull out something very special.

We nearly had an almighty shock in the men's long jump, where Olympic champion Miltiadis Tentoglou no-jumped with his third effort.

The Greek was ninth after three jumps, with only the top 10 progressing to the latter stages.

Neil Gourley speaking to BBC Sport after winning men's 1500m silver: "It feels really good. A couple of weeks ago I came away really disappointed with the European indoors race and I came here with a point to prove, just to myself.

"It was a change in tactics today. It was a case of if you can't beat him [Jakob Ingebrigtsen], join him. It worked out better today because it meant I fed off his momentum and I felt much better doing it that way. I just left a little too much to do in the home straight to catch him.

"This time last year I watched the world indoors because I was really injured, I could barely walk, and it was in my hometown in Glasgow. Anything else was a bonus today, I went with the mentality of anything is possible."

Arguably the most impressive individual showing of these championships comes from Gudaf Tsegay, who crushed the field by four and a half seconds.

The Ethiopian came home in 3:54.86, a new record for the World Indoors.

Another runner from Ethiopia, Diribe Welteji, took silver as she narrowly held off Britain's Georgia Hunter Bell.

Hunter Bell, the Olympic bronze medallist, matches that achievement here with a fine run to help scrub the memory of her fourth place in Glasgow last year.

Final lap, and Gudaf Tsegay is only getting quicker.

Hunter Bell is up to third!

Gudaf Tsegay virtually has the gold sewn up, it is about the other places now.

There is a pack of three competing for silver and bronze, Georgia Hunter Bell is among them.

Four laps to go, and Gudaf Tsegay is fully 30m ahead of the rest of the field. Dominant.

Georgia Hunter Bell is currently fourth.

Wow, Gudaf Tsegay has really sprinted away. She's already got clear air between her and the field.

Her fellow Ethiopian, Diribe Welteji, is currently second.

Away we go.

Gudaf Tsegay is the favourite and the Ethiopian wangts to lead from the front, immediately taking the lead.

So, we've already had one British medal on the track. How about a second?

Georgia Hunter Bell is on the start line for the women's 1500m final.

We have some bad news to bring you from the shot put however.

Britain's Scott Lincoln fouled on his second and third efforts and was 12th after three throws. With only the top 10 continuing in the final after that point, it means it is all over for Lincoln unfortunately.

A slightly awkward celebration from Jakob Ingebrigtsen, miming starting a motorbike after taking the gold.

He's a better runner than he is an actor.

Neil Gourley lifts the British flag aloft with a huge smile on his face.

He ran a brilliant race there and pushed one of the best to ever do it all the way. No shame in finishing second to Jakob Ingebrigtsen.
