Josh Kerr ended a sensational season by being crowned Britain’s first winner at the Ultimate Championship with a dominant 1500m victory – and earning $150,000 – as the inaugural edition of athletics’ new global event concluded in Budapest.

Kerr smashed the 27-year mile world record at the London Diamond League and won Commonwealth Games gold in Glasgow this summer, after beginning an outstanding year by reclaiming the world indoor 3,000m title.

In the shape of his life, Kerr swept past American Yared Nuguse on the back straight in Hungary and would not be denied once he had made his move to the front, taking victory in three minutes 29.35 seconds.

“I am a major championship guy and I will always be that,” Kerr, 28, told BBC Sport.

“From seven weeks ago in London, I went home, I chopped wood and carried water and I was ready to go again.

“Sometimes you have to come out of it to dig deeper inside and go further in life. Two weeks before [a race] I try to do something to get me out my routine and then I push myself for the last couple of weeks.

“I had a great build and, if I didn’t finish with a win, then that was on me.”

The 2023 world champion did not qualify by right for the Ultimate Championship, which is reserved for reigning global champions, Diamond League winners and others based on world ranking.

He was instead awarded an exceptional invitation by World Athletics, alongside rival Jakob Ingebrigtsen – although the pair’s eagerly anticipated reunion did not transpire after the Norwegian withdrew following his 5,000m win on Friday.

Kerr was peerless as he seized the opportunity to put on one final show this season – and take his share of the biggest prize pot in the sport’s history.

Over the past three nights, the world’s top athletes competed for a new title and a total prize fund of $10m (£7.4m) at the innovative event, which World Athletics president Lord Coe hopes can play a key role in shaping the sport’s future.

Speaking after his victory, Kerr referenced the “stick” he receives for not competing as much as others.

But he is in no doubt that it is because of that approach that he is able to seize the career-defining moments when they arrive.

In response to criticism from Ingebrigtsen over his decision to skip the European Championships in Birmingham, Kerr said he “was not a robot” and would continue to approach each season by targeting only a few competitions to avoid injury and maintain consistent high levels of performance.

While the Ultimate Championship was not one of those dates at the beginning of the year, it was no surprise that World Athletics made sure he could be present – nor that Kerr took the sport’s governing body up on the offer.

Kerr is, after all, blockbuster. He underlined his position as one of the sport’s biggest draws when he boldly announced his record-breaking intentions months in advance before delivering his historic mile performance in front of 60,000 British fans in July.

There were also no mistakes in Scotland, despite the pressure which came with his role as headline act in front of an expectant home crowd.

It is just 12 months since Kerr’s world title defence was ended by a calf tear in Tokyo.

But, having recovered to reach career-best fitness, the next three years now provide him with the opportunity to cement himself among the all-time greats.

With two World Championships – the second potentially in London – either side of the next Olympic Games, Kerr will continue to ignore the outside noise and follow his established winning formula.

“Obviously I get a lot of stick for not racing so much,” Kerr said. “But it allows me to come here fresh and ready to go.”

Amy Hunt produced a season’s best time in the women’s 200m final to end her championship on a positive note following disappointment in the 100m.

The 24-year-old, winner of four European golds last month, said she did not feel she had done herself “proud” after placing eighth in the 100m final on Saturday.

But Hunt improved to fourth in the 200m, in a time of 22.10 seconds, as American Melissa Jefferson-Wooden became the third-fastest woman in history in completing her sprint double.

“Yesterday was bad but I came back today and used it as fuel and motivation,” Hunt told BBC Sport.

“It was incredible to be part of an incredible race. This is what women in sport looks like; muscles, blood, sweat, tears.

“It has been really special to prove myself against the best in the world. It was the first time I have won a world semi-final. It is a massive confidence boost.”

After running the joint-seventh fastest 100m by a woman in history just 24 hours earlier, world champion Jefferson-Wooden, 25, produced the fourth-fastest women’s 200m time ever recorded with 21.47secs in the final event of the weekend.

“I did not see 21.47 coming tonight!” Jefferson-Wooden said. “I was thinking I could run this fast in maybe two years, but not tonight. I really have no words. This result is a good inspiration for the upcoming years.”

Earlier, GB’s mixed 4x400m relay quartet finished second to the USA following a superb anchor leg by Charlotte Henrich.
