Neil Gourley goes into races with a huge confidence. He always puts himself in the best position possible.

He spoke in his British team captain speech about this being the only week that matters and telling the athletes they should go out and give it their all.

Here's Jakob...

GB's Neil Gourley is among those who will try to stop him.

An intriguing long jump final is emerging meanwhile, as Olympic champion Miltiadis Tentoglou only jumps 7.91m with his second effort, leaving him down in seventh.

Mattia Furlani of Italy is the current leader.

That was an incredible collision between Sander Skotheim and Johannes Erm there, the pair all but came to blows as they went around that final lap.

They seem to have made up quickly however, shaking hands and now posing together with their respective national flags.

Onto the final lap, and the two leaders clash!

Sander Skotheim and Johannes Erm literally go shoulder to shoulder around the bend, a bit of argy-bargy there.

Skotheim will win gold, but Erm quite literally going down fighting.

They are away. Johannes Erm, currently second overall, needs to finish four and a half seconds ahead of Sander Skotheim to take gold.

It would be amazing if the Estonian managed that.

Sander Skotheim leads the field into the 1,000m, and this is one of the Norwegian's strongest events. He has the quickest personal best of anyone in this field.

The Brit is ninth of the 15 competitors so far, and needs to up his game to be in with a shot of a medal.

The first round of jumps have been completed, and Australia's Liam Adcock is the early leader with a distance of 8.28m.

Australia have enjoyed a strong championships with five medals so far.
