During the first significant track meet following the Paris Games, Olympic champion Emmanuel Wanyonyi achieved the fourth-fastest 800-meter time in recorded history.

Wanyonyi completed the race in 1 minute, 41.11 seconds, surpassing his previous winning time in Paris by 0.08 seconds. This remarkable feat equaled Wilson Kipketer’s 1997 world record time. Notably, only Wanyonyi’s fellow Kenyan, David Rudisha, has surpassed this exceptional performance in the 800-meter event.

“I’m so happy to have run that crazy time here in Lausanne,” Wanyonyi said. “I really loved the crowd here.”

The Athletissima meet resumed after a brief hiatus for the Olympics, marking a swift and early commencement to the renowned Diamond League circuit.

Jakob Ingebrigtsen reasserted his dominance in the men’s 1,500-meter race, overcoming a surprising fourth-place finish in Paris to decisively defeat Olympic champion Cole Hocker by a significant margin of over two seconds.

In the men’s 200-meter event, Olympic champion Letsile Tebogo maintained his exceptional form despite a recent return trip to his home country of Botswana. He secured a remarkable victory with a time of 19.64 seconds, demonstrating remarkable composure and control as he approached the finish line.

“It was a great race for me here today,” said the 21-year-old Tebogo, who admitted on the eve of the race that he had not trained in the previous week.

Tebogo concluded the race with a time that was 0.14 seconds faster than Erriyon Knighton, who secured fourth place in Paris.

Noah Lyles, the Olympic champion in the 100 meters and bronze medalist in the 200 meters in Paris, opted out of the Swiss competition.

The highlight of the event was the impressive performance by 20-year-old Wanyonyi, who overtook Marco Arop on the back straight and finished 0.61 seconds ahead of the Canadian Olympic silver medalist.

Wanyonyi's time was just 0.20 seconds shy of David Rudisha’s world record of 1:40.91, which he set while winning his first Olympic title in London in 2012.

Ingebrigtsen achieved a winning time of 3:27.83, establishing a meet record in Lausanne, although this time would have only placed him fourth at the Olympics.

“For me, a lot of it has been mental including going home, taking some easy days and then getting back to work,” said Ingebrigtsen, who did win Olympic gold in the 5,000. “Tonight’s race gave me good answers.”

Hocker acknowledged the challenge of being announced as an Olympic champion, despite his impressive 3:29.85 time, which was the second fastest of his career after his 3:27.65 in Paris.

Dina Asher-Smith achieved her season-best time of 10.88 in the women’s 100-meter race. Notably, this time would have secured a bronze medal in Paris, where the British athlete unfortunately did not qualify for the final.

“After the Olympics I took some time to refocus and now I’m just enjoying running, feeling fit and injury free,” Asher-Smith said.

Olympic champions Yaroslava Mahuchikh in the women's high jump and Miltiadis Tentoglou in the men's long jump both secured victories once again.

Mahuchikh successfully cleared a height of 1.99 meters, while Tentoglou surpassed the eight-meter mark on his sixth attempt, achieving a distance of 8.06 meters.

This performance allowed him to claim victory over Wayne Pinnock, the silver medalist from Paris, who had initially led with a jump of 8.01 meters. It was a successful evening for Olympic bronze medalists, who also triumphed two weeks later.

In the 110-meter hurdles, Olympic gold medalist Grant Holloway was narrowly defeated at the finish line by the fast-approaching Rasheed Broadbell, who won with a time of 13.10 seconds, avenging his previous result in Paris.

Femke Bol triumphed in the women's 400-meter hurdles with a time of 52.25 seconds, following her third-place finish in Paris behind Sydney McLaughlin-Levrone's world-record performance. Jasmine Camacho-Quinn claimed victory in the women's 100-meter hurdles with a time of 12.35 seconds, while Mary Moraa won the women's 800 meters in 1:57.91.

The men's javelin competition reached its peak in the sixth and final round, showcasing season-best throws from Anderson Peters and Neeraj Chopra, who had finished third and second at the Olympics, respectively. Peters achieved a throw of 90.61 meters to maintain his lead, while Chopra followed closely with a throw of 89.49 meters.

Olympic champion Arshad Nadeem did not participate in the event on Thursday. In the men's 400 meters, Olympic silver medalist Matthew Hudson-Smith from Britain finished under 44 seconds, winning with a time of 43.96 seconds.

Similarly, Chase Jackson emerged victorious in the women's shot put after failing to qualify for her Olympic final, recording a winning mark of 20.64 meters, which was over three meters farther than her best effort in the Olympic qualifying round.

The Diamond League will continue with four additional meetings: on Sunday in Silesia, Poland; on August 30 in Rome; the Weltklasse meet in Zurich on September 5; and the finals meet in Brussels on September 13-14.
