Melissa Jefferson-Wooden is in a class of her own!

"Woahhh!" she says as she crouches to the ground and tries to take in what she has just done.

A sensational time of 21.47 seconds leaves Olympic champion Gabby Thomas unable to get close despite a strong finish.

Another sprint double for the USA.

Great Britain's Amy Hunt clocks a season's best 22.10 for fourth, behind another American in Kayla White.

It's the final event of the first ever Ultimate Championship.

And it's all set up for a big finish.

World champion Melissa Jefferson-Wooden. Olympic champion Gabby Thomas. European champion Amy Hunt.

On your marks...

Amy Hunt produced an impressive win in her 200m semi-final a little earlier this evening.

Having been left disappointed by her performance in last night's 100m final, that will have put the 24-year-old in a much more positive frame of mind before her latest bid for a major title.

The competition, including 100m winner Melissa Jefferson-Wooden, is fierce, however.

Complete dominance from Kenneth Bednarek!

The American clocks a world-leading 19.52 seconds as he charges away from his rivals.

Letsile Tebogo cannot get close, crossing the line in 19.76, with American Courtney Lindsey third in 19.79.

That's a sprint double for Bednarek - and a whopping $300,000 from those two victories in addition to his two Ultimate trophies.

Not a bad weekend's work...

This should be a brilliant dust-up.

Who will take the men's 200m title?

Saly Sarr has got a big future ahead of her, she is just 23 years of age and the ultimate champion.

Nobody can surpass Saly Sarr's leading leap in the final round of the women's triple jump final!

The Senegal athlete's first-round best of 15.06m takes her to the title.

Gianmarco Tamberi can't produce the personal best leap over 2.41m he desperately hoped to produce for his engaged audience, but the men's high jump Ultimate champion still sprints off to celebrate with the crowd afterwards.

What a show he has put on.

Two more exciting finals to come on the track, before the curtain falls on the inaugural Ultimate Championship.

The men's and women's 200m are not far away, with Great Britain's Amy Hunt involved in the final race of the night at 19:49 BST.

We're down to the final four in the women's triple jump final.

Saly Sarr, of Senegal, still leads after her opening leap of 15.06m.

But Cuba's Davisleydi Velazco is within two centimetres of that before the final round...

That was a piece of supreme 1500m running.

Josh was totally in control, he didn't have to make many moves.

But, when he did, it was the right one.

A huge grin on the face of Josh Kerr as he lifts his Ultimate trophy.

What an incredible year it has been for him.

World indoor gold, the mile world record, Commonwealth gold on home soil, and now the first 1500m Ultimate champion.

He knew he was never letting anyone deny him today.

Gianmarco Tamberi is proving the star of the show in his end of the sold-out arena!

The Italian goes clear at 2.37m to put the title out of reach for American JuVaughn Harrison, who finishes with a best of 2.30m.

Tamberi calls for the bar to be raised even higher!

It's going to 2.41m - a height cleared by only six men in history.

He made that look so good. Josh Kerr grabbed hold of the race and in the form he is in now, it is going to be really hard to get past him.

Never in doubt!

Josh Kerr will not be denied as he takes control before powering to victory in three minutes 29.35 seconds.

Australian Cameron Myers is the only one who can get remotely close in the end.

Yared Nuguse continues to push the pace at the front.

Josh Kerr moves on to the American's shoulder...

And now Kerr hits the front before the final bend!

Josh Kerr begins to work his way through the pack.

The race win predictor has Josh Kerr projected to finish 13th, based on world rankings in 2026. Hmm.

Kerr does not race often, instead prioritising a few big moments each year, and required an exceptional invitation to this event.

Away they go!
