Emmanuel Wanyonyi at the Monaco Diamond League/ HANDOUT

After what has been a mixed bag of results in his Diamond League campaign, World and Olympic 800m champion Emmanuel Wanyonyi will be keen to produce a statement victory when he renews his long-standing rivalry with Canada’s Marco Arop at the Lausanne Diamond League on August 21.

Wanyonyi launched his 2026 campaign over 1,500m at the Kip Keino Classic on April 24, delivering a commanding display to claim victory in 3:34.11. He finished ahead of world bronze medallist Reynold Cheruiyot, who clocked 3:34.73, while Daniel Munguti completed the podium in 3:36.21.

The middle-distance ace then opened his Diamond League campaign in Rabat on May 31, where he was forced to settle for second place over his preferred 800m distance, timing 1:43.56. England’s Max Burgin stunned the Kenyan star to race to victory in 1:42.98, as Algeria’s Slimane Moula completed the podium after clocking 1:43.73.

In his second Diamond League race of the year in Oslo, Wanyonyi was once again forced to settle for second place, clocking 1:42.09, just one hundredth of a second behind American Cooper Lutkenhaus, who snatched victory in 1:42.08.

However, Wanyonyi hit back emphatically in his third Diamond League outing in Monaco, obliterating the men’s 1,000m world record.

In Monaco, the Kenyan sensation erased the 27-year-old world 1,000m record of 2:11.96, set by compatriot Noah Ngeny in 1999, storming across the finish line in a breathtaking 2:11.83.

The stunning run saw Wanyonyi finish comfortably clear of Britain’s Jake Wightman, who clocked 2:12.77, while Algeria’s Djamel Sedjati settled for third in 2:13.94.

His most recent Diamond League appearance, however, failed to yield the desired result as he finished fourth over 800m in London, clocking 1:43.31.

That race saw American Brandon Miller claim victory in 1:42.19, as Ireland’s Mark English placed second in 1:42.97, with Burgin completing the podium in 1:43.30.

In recent years, Wanyonyi has admitted that the men’s 800m is becoming increasingly competitive, with the margins between victory and defeat growing ever thinner. “It’s not easy to be consistent, to win the 800m, because it is so competitive,” Wanyonyi said in a previous interview with World Athletics.

Wanyonyi now heads to the Lausanne Diamond League, a track where he has produced some of the most eye-catching performances of his burgeoning career. It was at the 2024 Lausanne meeting, where the 22-year-old timed 1:41.11 to post the joint second-fastest time in history alongside Wilson Kipketer.

Wanyonyi’s mark fell just shy of the world record of 1:40.91 set by Kenyan legend David Rudisha at the 2012 London Olympic Games.

The Kenyan will also be hoping to improve on his 2025 outing in Lausanne, where he had to settle for second place in the 800m after clocking 1:43.29 behind American Josh Hoey, who stormed to victory in 1:42.82.
