Emmanuel Wanyonyi and Marco Arop in a previous race/ HANDOUT

Olympic 800m champion Emmanuel Wanyonyi will rekindle his fierce rivalry with Olympic silver medallist Marco Arop of Canada at the star-studded Monaco Diamond League meeting this Friday. 

The much-anticipated clash marks their first head-to-head since the Kingston Grand Slam on April 6. ‎In that race, Arop edged Wanyonyi to win in 1:45.13 with Wanyonyi settling for second place in 1:46.44. ‎American Bryce Hoppel was third in 1:47.02.

‎With both athletes firmly eying this season’s ultimate prize, the Tokyo World Championships, the Monaco duel will serve as a critical dress rehearsal and Wanyonyi is keen to land a psychological blow with his first win over Arop this year.

The two middle-distance titans delivered a series of electrifying encounters last season, headlined by their Olympic final thriller in Paris on August 10. 

‎Wanyonyi stormed to Olympic gold in 1:41.19, just a whisker ahead of Arop’s 1:41.20. 

‎Algeria’s Djamel Sedjati clinched bronze in 1:41.50. Twelve days later, the duel resumed in Lausanne, where Wanyonyi again had the upper hand, clocking 1:41.11 to Arop’s 1:41.72. ‎France’s Gabriel Tual was third in 1:42.30.

‎Their rivalry remained intense in Silesia three days later, where Arop hit back with a commanding 1:41.86 victory as Wanyonyi faded to second in 1:43.23. But the Kenyan had the last laugh at the Brussels Diamond League final, capturing the trophy in 1:42.70 ahead of Sedjati (1:42.86) and Arop (1:43.25).

‎Fast forward to 2025 and Wanyonyi has already stamped his authority on the Diamond League circuit with commanding back-to-back wins, leading the standings with 22 points.

After a sluggish start in Rabat on May 25, where he finished third in 1:43.37 behind Botswana’s Tshepiso Masalela (1:42.70) and Britain’s Max Burgin (1:43.34), the 2023 World silver medallist bounced back emphatically. ‎He clocked 1:42.78 to win in Oslo on June 12, then followed it up with a 1:41.95 victory in Stockholm on June 15, holding off Sedjati (1:42.27) and American Josh Hoey (1:42.43).

‎Despite his win in Stockholm, Wanyonyi highlighted a need to sharpen up on his speed. ‎"I have a lot of mileage in my legs and need to start speedwork to improve my finish," Wanyonyi said post-race. ‎"I was very happy to run under 1:42 especially so soon after winning in Oslo," he added.

‎Arop, meanwhile, will be making his Diamond League season debut in Monaco. ‎His last 800m outing came at the Philadelphia Slam, where he cruised to victory in 1:43.38, ahead of Americans Hoey (1:44.41) and Yared Nuguse (1:45.36). Adding more depth to the star-studded cast in Monaco are Sedjati and Americans Hoey and Hoppel.

‎Also in the fold are Tual of France, Britain's Burgin, Spain's Mohamed Attaoui, Algeria's Slimane Moula and Poland's Patryk Sieradski.
