• Controversial start-up reaches out to British athletes

• Olympic swimmer Ben Proud became first Briton to join

British athletes across multiple sports are being targeted by the Enhanced Games after the US sprint star Fred Kerley became the biggest name yet to sign up for the controversial event.

Kerley, the world 100m champion in 2022, said he was joining the Enhanced Games, which allows athletes to take performance-enhancing drugs that are banned in official events, to become the fastest man ever.

• Silver medal for Briton in Tokyo as injury thwarts Kerr

• Just 0.02sec separates first from second in 1500m final

When Jake Wightman sat on the bus to the 1500m heats at the World Athletics Championships on Sunday, he told himself that if he failed to make it through he was done. He was 31. His body was breaking down so often that he felt he had post‑traumatic stress disorder. And he feared his best days were behind him. Yet, just three days later, what had seemed like a final hurrah became a glorious resurrection.

What a fighter. What an athlete. What a 1500m final. Most expected this to be a shootout between Britain’s defending champion, Josh Kerr, and the young Dutch star Niels Laros. Instead the script was flipped on its head and ripped into pieces. Twice.

• Former sprinter claims he is facing own financial losses

• ‘Michael has asked for patience while we try to fix this’

Michael Johnson’s Grand Slam Track organisation has denied the former American sprinter has pocketed $2m from the series while athletes have gone unpaid, calling the speculation “categorically false” – and claimed he was facing financial losses himself.

Johnson is facing the prospect of legal action from athletes, agents and the suppliers who helped stage three GST meetings, with sources claiming they are owed as much as $19m (£13.9m). It is understood that two athletes claim they had to withdraw from buying a house when prize money was not paid, and many privately believe they will never receive their money.

• American is targeting the 40-year 400m world record

• Kipyegon is first woman to win four 1500m world titles

First Tokyo witnessed the spectacular. Then came a divine act of Faith.

In the women’s 400m, Sydney McLaughlin-Levrone ran one of the fastest times in history, easing down, to raise the question of whether one of the oldest – and most controversial – track and field records might fall this week.

• World champion says ‘only matter of time’ to run 9.6sec

• Seville dismisses effect of Noah Lyles’s mind games

On Sunday night, Oblique Seville became the first Jamaican to win the men’s 100m world title since Usain Bolt. But it turns out the 24-year-old’s mind is just as quick as his blistering leg speed.

In an interview to celebrate his victory, Seville was asked if he were to design a sprinter what would he look like. The questioner expected a long answer. Perhaps Justin Gatlin’s start, Michael Johnson’s mentality, and Bolt’s leg speed. But one word came back from Seville’s mouth almost instantaneously. “Usain.”

• Swede clears 6.30m to claim gold in Tokyo

• Shoes with metal spike enable faster run-up

The pole vault competition was two hours and 20 minutes old when Mondo Duplantis finally got serious at these World Athletics Championships. The bar had just been raised to six metres. So Mondo reached into his kitbag and dug out the Claw.

It is his weird looking special shoe, with a spike protruding from the front of it like a medieval torture implement – and the 25‑year‑old Swede takes it out only on those occasions when he sniffs a world record in the air.

• He says his generation ‘just more talented’ than today’s

• Legendary sprinter no longer runs and is ‘into Lego now’

Usain Bolt made his comeback to the world of track and field on Sunday night and, for a moment, it was like the good old days. There was his trademark To Da World pose before the 100m finals. The cheers and adulation of 60,000 fans in Tokyo’s National Stadium. A reminder of glories past.

The 39-year-old Jamaican had not watched athletics at all since retiring in 2017 until seeing Melissa Jefferson-Wooden and Oblique Seville win gold. And, as he also admitted, he now spends his time streaming movies and building Lego – and even gets out of breath when he walks up stairs.

• Kishane Thompson takes silver with Lyles landing bronze

• Usain Bolt watches on in delight with Jamaican one-two

When Oblique Seville was 10, he told his mother he wanted to be trained by Usain Bolt’s coach Glen Mills. That came to pass when he joined the famous Racers Track Club in Jamaica. Now, on a night of exhilarating speed and twisting drama, he achieved a far bigger dream and emulated his hero by becoming the 100m world champion.

To make it even sweeter, he deli­vered the greatest performance of his career in front of Bolt himself, who was cheering and ­punching the air like a superfan as Seville ran down his ­fellow Jamaican Kishane ­Thompson in the final metres to secure gold in 9.77sec.

• Peres Jepchirchir denies Tigst Assefa to claim gold

• Julia Paternain learns of medal after crossing the line

Julia Paternain wasn’t sure where she had finished after a punishingly hot women’s marathon at these World Athletics Championships in Tokyo. So, as she crossed the line, she asked an official.

The answer had Paternain, the world’s 288th-ranked marathon runner, staring back at him in disbelief. She had won a bronze medal, Uruguay’s first ever at a world athletics championships.

• Beatrice Chebet roared on to 10,000m gold in Tokyo

• Kishane Thompson and Julien Alfred shine in 100m

There was a moment on the opening night of the World Athletics Championships when the bottled-up frustration of missing out on a full-fat Tokyo Olympics – with crowds and fun and unbridled joy – suddenly seemed to be unleashed. It came at the end of the women’s 10,000m, a roar that could have been heard on Mount Fuji, a vast outpouring of appreciation and pride.

At the front of the pack, four contenders were whittled down to two before the Olympic and world champion, Beatrice Chebet, took off with Italy’s Nadia Battocletti in pursuit. It was like watching Wile E Coyote chasing Roadrunner.
