Chepkoech ensured Kenya's dominance of the 3,000 metres steeplechase continued, setting a personal best of 9min 27.4sec to claim gold.

Ethiopia's Zerfe Wondemagegn won silver in a time of 9:35.22, while Kenya's Faith Cherotich secured bronze in 9:44.76.

In the men's long jump, Konate produced an under-20 world-leading jump of 8.12 metres. 

He led Jhon Andres Berrio of Colombia, who jumped 7.97m, and Kavian Kerr of Jamaica on the podium, the latter reaching 7.90m with his third jump.

The other finals in the field in the evening session saw the Czech Republic's Jan Doležálek win the men's hammer, throwing an under-20 national record of 77.83m, 18-year-old Maja Åskag of Sweden take women's triple jump gold with 13.75m and Janne Läspä winning Finland's second gold of the championships in the men's javelin with a throw of 76.46m.

In the morning session, Belarus' Matvei Volkov took a dramatic gold in the men's pole vault, which was delayed from yesterday due to weather issues. 

"I like pressure," said Volkov, who cleared 5.45m with his final attempt. 

"I felt by myself what I needed to change [for the final attempt] and my father just gave me a kick, 'let’s jump.'"

In the women’s discus final Violetta Ignatyeva, competing with Authorised Neutral Athlete status, was a dominant winner, eventually throwing 57.84m to claim gold.

"I’m really grateful to my coaches and the entire team that made it possible to take part in this," Ignatyeva said. 

"It’s even better that I managed to win gold."

South Africa’s Mine de Klerk threw an African under-20 record of 53.50m to claim silver.

Those were the only gold medals decided today, but perhaps the best performance came in the 110 metres hurdles.

Frenchman Sasha Zhoya qualified fastest from the semi-finals in the evening, breaking the under-20 world record with 12.93sec.

Zhoya flirted with the record in the morning's session, running 13.12 in the opening heats.

Udodi Chudi Onwuzurike of Nigeria qualified fastest in the men's 200m, with 100m champion Botswana's Letsile Tebogo in second, setting a personal best of 20.31.

In the women's 200m, Namibia's Beatrice Masilingi, who was one of the favourites entering the 100m final before finishing second, qualified fastest in 22.19, setting a championship record in the process.

The first day of the decathlon also came to a close, with Jente Hauttekeete of Belgium leading the way.

The 19-year-old won three of the four disciplines to open up a clear lead of more than 200 points ahead of František Doubek of the Czech Republic.
