Monaco Diamond League 2023: Faith Kipyegon demolishes mile world record and Karsten Warholm scorches to 400m hurdles victory - as it happened

Faith Kipyegon broke her third world record of the year to steal the show at the Monaco Diamond League athletics meet on Friday (21 July).

Sifan Hassan held the previous best with 4:12.33 at this meeting four years ago, but the double Olympic 1500m champion - who set new marks in the 1500m and 5000m earlier this season - consigned it to history in emphatic fashion.

The Kenyan crossed the line in 4:07.64, more than four and a half seconds quicker than Hassan's mark, to cement her reputation as the greatest female middle-distance runner of her generation.

Karsten Warholm was almost as impressive in the men's 400m hurdles as he easily saw off the challenge of reigning world champion Alison dos Santos with the fourth fastest time in history.

There was a rare defeat for Mondo Duplantis as Chris Nilsen took the pole vault, but Shericka Jackson won the women's 200m and Nia Ali set a new world lead time in the 100m hurdles.

Ferdinand Omanyala capped an excellent night for Kenyan athletes with his first Diamond League victory in the 100m.

Read on to find out what happened, as it happened, on a spectacular night of athletics inside the Stade Louis II.

22:00 Omanyala scores another win for Kenya

Ferdinand Omanyala rounded off a great night for Kenyan athletes with his first Diamond League victory in the men's 100m.

A photo finish was needed to split him and Botswana's Letsile Tebogo, but Omanyala won in 9.92 with Tebogo clocking 9.93.

Ackeem Blake was third in 10.00 ahead of fellow Jamaican Yohan Blake.

Moments earlier, Hugues Fabrice Zango of Burkina Faso won the men's triple jump in dramatic fashion.

With the very last jump of the competition, Zango sailed out to 17.70m to deny 18-year-old Jamaican Jaydon Hibbert. Yasser Triki of Algeria was third.

21:45 Remember the name - Simon Koech

Kenya may have found someone to challenge Olympic steeplechase champion Soufiane El Bakkali in the form of Simon Koech.

The 20-year-old produced a strong front-running performance, pulling clear of compatriot Abraham Kibiwot to win in 8:04.19 and take more than 14 seconds off his personal best.

Abrham Sime was third, just ahead of fellow Ethiopian Samuel Firewu.

Jayden Hibbert passed in round five of the triple jump but is safely in the triple jump Final 3 thanks to his 17.66m in round four.

Yasser Triki (17.32m) and Hugues Fabrice Zango (17.15m) will join him in having sixth and final attempts.

American veterans Will Claye and Christian Taylor were seventh and eighth respectively in the eight-man contest.

The triple jump Final 3 will take place before the last event of the night, the men's 100m.

21:35 Shericka Jackson storms clear in women's 200m

Shericka Jackson finished powerfully to win the women's 200m in Monaco in a time of 21.86.

The reigning world champion was clear of young St Lucian athlete Julien Alfred who continues to make a big impression after her 100m defeat of Sha'Carri Richardson in Silesia on Sunday.

Dina Asher-Smith, world champion in 2019, ran a season's best in third with Olympic bronze medallist Gabby Thomas the disappointment of the race in seventh place.

In the men's triple jump, 18-year-old Jamaican Jayden Hibbert showed his prodigious talent with 17.66m in round four to take the lead.

Yasser Triki of Algeria is second with 17.32m ahead of Burkina Faso's Hugues Fabrice Zango.

Double Olympic and four-time world champion Christian Taylor lies eighth thanks to his second-round jump of 16.20m.

Nicola Olyslagers (formerly McDermott) took victory in the women's high jump after she cleared 1.99m with her third and final attempt.

The Australian was the only athlete to clear that height having also needed three goes at 1.96m.

Yaroslava Mahuchikh failed with her one attempt at 2.01m after seeing Olyslagers' successful clearance. She was third behind Iryna Gerashchenko on countback after both women cleared 1.96m.

21:20 Mondo Duplantis beaten in pole vault

There was a huge upset in the men's pole vault as Mondo Duplantis finished only fourth in the pole vault behind Chris Nilsen.

Sweden's world record holder failed twice at 5.92m with Nilsen clearing that height on his first attempt.

Duplantis and EJ Obiena both chose to have one attempt at 6.02m, and both failed as Nilsen scored a rare win over the world and Olympic champion.

Obiena was second on countback ahead of Kurtis Marschall with Duplantis tied for fourth place after a best clearance of 5.72m.

Hagos Gebrhiwet secured a gritty win in the men's 5000m, making his victory bid some 600m from home before kicking again with 300m to go.

Berihu Aregawi looked like he might catch his fellow Ethiopian, but the 29-year-old stayed clear to win in a personal best of 12:42.18.

Telahun Bekele was third in another personal best with Mo Katir fourth and Ugandan star Jacob Kiplimo only sixth.

21:00 Nia Ali sets another world lead on the night

There has already been a host of world-class performances at the Stade Louis II tonight with the latest coming from Nia Ali in the women's 100m hurdles.

The 2019 world champion clocked a world lead and personal best of 12.30 to edge out fellow American Keni Harrison by one one-hundredth of a second.

Ali also broke Gail Devers' meeting record of 12.42 set 21 years ago.

Alaysha Johnson was given third as she and Tia Jones both recorded times of 12.39 with Americans filling the first four places.

Iryna Gerashchenko of Ukraine leads the women's high jump after clearing 1.96m at the first attempt.

And could we be about to see an upset in the men's pole vault? Chris Nilsen leads after a first-time clearance at 5.92m with Mondo Duplantis only fourth at present.

The super Swede failed with his first attempt at 5.92m having skipped 5.82m which EJ Obiena and Australia's Kurtis Marschall cleared first time.

The men's 5000m is underway with 3000m world record holder Mo Katir and Jacob Kiplimo among those aiming for a fast time.

20:45 Faith Kipyegon smashes mile world record by over four seconds!

It's a third world record of 2023 for the incredible Faith Kipyegon.

Sifan Hassan set the previous best of 4:12.33 at this meeting four years ago. And when the second of two pacemakers left Kipyegon on her own in front with 600m to go, the Kenyan was well clear of the Wavelight showing world record pace.

Kipyegon was close to her own 1500m world record as she took the home turn, and her famed finishing kick saw her cross the line in 4:07.64, more than four and a half seconds inside Hassan's mark.

Ciara Mageean broke Sonia O'Sullivan's Irish record with 4:14.58 in second ahead of Ethiopia's Freweyni Hailu.

Laura Muir set a new British record of 4:15.24 in fourth ahead of Jessica Hull's Australian record and Nikki Hiltz's North American best in sixth.

20:30 Kaczmarek flies home in women's 400m; Kinyamal sets men's 800m world lead

With Sydney McLaughlin-Levrone missing due to a knee injury, another American hurdler - Shamier Little - looked like taking the women's flat 400m.

Out in lane eight, Little seemed to have the race in her grasp but faded badly in the closing stages with Poland's Natalia Kaczmarek coming home strongly to back up her victory on home soil in Silesia on Sunday.

Kaczmarek's winning time was 49.63 with Little clocking a personal best of 49.68 in second and Lieke Klaver (49.99) third.

Then there was a rapid men's 800m with Kenya's Wyclife Kinyamal moving to the front with 250m to go and staying clear to win in 1:43.22, the fastest time in the world this year.

Slimane Moula could not quite catch him and was second in 1:43.40 with Marco Arop third as less than three-tenths covered the top three.

There was no improvement in the men's javelin Final 3 with Jakub Vadlejch taking victory thanks to his opening throw of 85.95m. Julian Weber was second with Keshorn Walcott third.

20:15 Karsten Warholm runs fourth quickest 400m hurdles in history

Karsten Warholm was at his brilliant best in the first track event of the night, the 400m hurdles.

The Olympic champion and world record holder was up against reigning world champion Alison dos Santos who was making his seasonal debut in the event having ran a solid flat 400m at the weekend.

Warholm fairly flew out of the blocks in lane seven with the Brazilian trying to stay with him for the first half of the race.

And dos Santos faded as the Norwegian continued to pour it on at the front, crossing the line in a Diamond League record and 2023 world lead of 46.51.

It was Warholm's second fastest run of his career and the fourth quickest time in history.

Dos Santos clocked 47.66 with CJ Allen third in 47.84.

Mondo Duplantis and Sam Kendricks were among the four men to go over 5.72m first time in the men's pole vault.

Jakub Vadlejch still leads the men's javelin from Julian Weber, but Keshorn Walcott is into third thanks to his fifth-round throw of 81.31m, displacing world champion Anderson Peters from the Final 3.

20:00 Larissa Iapichino snatches long jump victory

The women's long jump Final 3 provided drama as Italy's Larissa Iapichino produced a personal best of 6.95m to take victory.

Tara Davis-Woodhall had to settle for second after failing to improve on her 6.88m from round five with Ivana Vuleta (6.86m) fouling her final jump to take third.

French veteran Renaud Lavillenie was an early casualty in the men's pole vault with the London 2012 gold medallist having three failures at 5.62m. Belgium's Ben Broeders is also out as eight men went over with the bar going up to 5.72m.

No change in the men's javelin with Jakub Vadlejch still in front with his opening throw of 85.95m.

The track action is about to get underway with Olympic 400m hurdles gold medallist and world record holder Karsten Warholm up against world champion Alison dos Santos.

19:45 Rojas only 10th in long jump as Jakub Vadlejch takes early javelin lead

With only the top eight in the long jump making it to round four, that was the end of Yulimar Rojas' night. She was 10th in the end with a best distance of 6.61m after Spain's Fatima Diame moved into the podium at the end of the third round with a jump of 6.74m.

Larissa Iapichino matched that distance in round four to move back into third place with a second-best leap of 6.72m.

But it was all change in round five as Tara Davis-Woodhall leapt 6.88m to take the lead from Ivana Vuleta (6.86m). And Iapichino made the top three for the final round with a jump of 6.81m to displace **Hilary Kpatcha (**6.77m).

Czech thrower Jakub Vadlejch took the early lead in the men's javelin with 85.95m. Julian Weber (84.23m) is second behind the Olympic silver medallist with double world champion Anderson Peters (79.64m) in third place after three rounds. There are just seven athletes in this competition.

The bar is at 5.62m in the men's pole vault with Americans Sam Kendricks and Chris Nilsen among those clear at the first time of asking. Mondo Duplantis is yet to open his account.

19:20 Ivana Vuleta leads women's long jump with Yulimar Rojas down in ninth

Yulimar Rojas is currently ninth in the long jump after fouling in round one, jumping 6.52m in round two and 6.61m in round three.

Ivana Vuleta (formerly Spanovic) has just taken the lead thanks to a third-round effort 6.86m which is a season's best for the Serbian.

France's Hilary Kpatcha is second thanks to her opening effort of 6.77m with Larissa Iapichino of Italy third on 6.72m. Jamaica's Ackelia Smith, who boasts the furthest jump of the world this year, lies fourth with 6.70m.

The men's pole vault has just started at an opening height of 5.42m. World and Olympic champion Mondo Duplantis is not expected to enter the competition until much later.

Monaco Diamond League 2023 preview

The ninth meet of the 2023 Diamond League athletics series is underway at Monaco's Stade Louis II on Friday (21 July).

Having already broken the 1500m and 5000m world records this season, Kenya's Faith Kipyegon sets her sights on Sifan Hassan's four-year-old mile mark of 4:12.33.

Sydney McLaughlin-Levrone was set to run in a competitive flat 400m against recent Silesia Diamond League winner Natalia Kaczmarek and Kenya's Commonwealth Games 800m champion Mary Moraa, but the 400m hurdles world record holder withdrew hours before the meet.

Before what was due to be her last race before next month's Budapest World Championships, McLaughlin-Levrone said on her Instagram Stories, "After discussion with my coach and doctor they have decided to pull me due to a reoccuring knee issue. My prayer is to get back to 100% health before the world championship."

The women's 200m features an intriguing clash between reigning world champion Shericka Jackson and USA’s Olympic bronze medallist Gabby Thomas. British pair Dina Asher-Smith and Daryll Neita, and St Lucia's young hopeful Julien Alfred - who defeated Sha'Carri Richardson in Silesia over 100m last weekend - are also in the line-up.

The men's 400m hurdles sees Olympic champion and world record holder Karsten Warholm go up against world champion Alison dos Santos with the Brazilian making his seasonal debut in the event having run the flat 400m at Silesia on Sunday.

In the field, pole vault king Mondo Duplantis is competing in what he says will be his last meet before the Worlds.

And triple jump superstar Yulimar Rojas is looking to achieve the World Championship long jump qualifying standard of 6.85m, with Jamaica's Ackelia Smith and USA's Tara Davis-Woodhall - two of the three women to exceed seven metres this season - also in the field.
