Kenya&rsquo;s world 5000m finalist Nicolas Kimeli won the men&rsquo;s 10,000m at the Gouden Spike meeting in Leiden, clocking a world-leading PB of 26:58.97.
The 21-year-old, contesting his first 10,000m race in three years, ran alongside compatriot Solomon Kiplimo Boit during the early stages, passing through 3000m just inside 8:12. Kimeli broke away from Boit just a couple of laps later and set off in pursuit of a sub-27-minute time.
Kimeli&rsquo;s lead grew with each lap, while Boit continued running in no-man&rsquo;s land. Further behind, Dutch runner Mike Foppen, making his debut over 10,000m, gradually detached himself from the main chase pack.
Kimeli forged on and started to sprint on the final lap when he realised a sub-27-minute performance was a possibility. He crossed the line in 26:58.97 to smash the meeting record by almost half a minute.
Boit finished second in 27:41.10, while Foppen placed third in 27:59.10. It was Foppen&rsquo;s eighth PB of the year, having set two at 1500m, one at 2000m, two at 3000m, plus national records for 5000m and 5km.
In fourth, Swedish teenager Emil Millan de la Oliva clocked a national U20 record of 28:23.21, just one second shy of the European U20 record of 28:22.48 set by Italy's Christian Leuprecht back in 1990.
As is tradition at this meeting, a golden spike trophy is presented to the top performer of the night. Unsurprisingly, Kimeli scooped that accolade.
Elsewhere in Leiden, Menno Vloon won the pole vault with 5.76m, the second-best clearance of his career after his 5.85m national record in 2017.
<h3>Warholm and Ingebrigtsen dominant at Norwegian Championships</h3>
Some of the country&rsquo;s biggest stars turned out in Bergen for the Norwegian Championships, which concluded on Sunday (20).
Just three days after winning in Rome with a meeting record of 47.07, two-time world champion Karsten Warholm won the 400m hurdles in 48.23, finishing more than five seconds ahead of the rest of the field.
Jakob Ingebrigtsen completed a middle-distance double, taking the 1500m title in 3:33.93 on Saturday &ndash; winning by 13 seconds &ndash; and then winning the 800m in 1:48.72 on Sunday.
A week after setting a world U18 heptathlon best of 6301, 17-year-old Henriette J&aelig;ger won the 400m in 52.90 and the 200m in 23.60 (-2.0m/s). She was also third in the long jump (6.04m).
Elsewhere, Amalie Iuel won the women&rsquo;s 400m hurdles in 55.63 and Zerei Kbrom Mezngi took the men&rsquo;s 10,000m title in 28:04.29.
<h3>Yamanishi impresses in Kumagaya</h3>
World champion Toshikazu Yamanishi stepped down in distance at the Japanese Inter-Corporate Championships in Kumagaya and won the 5000m race walk in 18:34.88, the fastest ever clocking by an Asian race walker.
Yamanishi had Eiki Takahashi, Tomohiro Noda and Satoshi Maruo for company in the early stages, but he gradually dropped them one by one before going on to win by almost 17 seconds. Takahashi finished second in 18:51.25.
Yamanishi&rsquo;s winning time is four seconds faster than the Asian record set by Yusuke Suzuki back in 2015, just three months after he set a world record over 20km.

In a high-quality men&rsquo;s 10,000m race, 2015 world U18 champion Richard Kimunyan emerged the winner in 27:01.42, finishing just one second ahead of Benard Koech (27:02.39) with Bedan Karoki a close third (27:02.80). Kimunyan&rsquo;s time was a world lead but lasted just eight hours at the top of the world list before it was bettered in Leiden.
The women's 5000m was similarly speedy, won by Kenya's Rebecca Mwangi in 14:55.32. National half marathon record-holder Hitomi Niiya was a close second in 14:55.83, while Ririka Hironaka placed third in 14:59.37. Niiya and Hironaka moved to second and third respectively on the Japanese all-time list.
On the infield, Tomohiro Shinno produced a lifetime best of 2.31m to win the men's high jump title, moving to fourth on the Japanese all-time list in the process. National record-holder Haruka Kitaguchi threw a season&rsquo;s best of 63.45m to win the women&rsquo;s javelin.
