Back on the London track where he won World Championship gold last summer, along with producing one of the images of the year with his eyes almost popping as he triumphed, Karsten Warholm was in dreamland again today.
On an amazing weekend for Norwegian athletics, Warholm smashed his own 400m hurdles national record and European U23 record with a glorious one-man show just weeks away from the European Championships in Berlin.
Running powerfully and fluently from lane seven in the second IAAF Diamond League meeting in less than 24 hours, Warholm won in 47.65. His time lowered the old national best of 47.81 which he had run in Stockholm last June and it was also a meeting record.
As he crossed the line, he punched the air with his right arm and pulled his bottom lip to extend his facial celebrations of delight, even though he could not quite match the extraordinary expressions of 11 months ago.
"I love this stadium and I love London," said Warholm, who beat defending European champion Yasmani Copello from Turkey in 48.44 and Ireland's Thomas Barr in 48.99.
"I am hoping to run my best in Berlin. I hate talking about medals but I have goals. I felt good today. It went exactly how I wanted it. I had good strides, good rhythm and if there was ever a good time to run a time like that, it was today," added Warholm.
Still only 22, Warholm will now head to the European Championships looking for his third gold medal in a year after his success also last summer at the European U23 Championships in Bydgoszcz.
Hughes clocks 9.93 in the 100m
The battle for European 100m supremacy will be something special in Berlin and Britain's Zharnel Hughes put down another marker on Saturday, even though he did not win.
Hughes did not make the best of starts in the final but came through superbly from lane five, but it was never going to be enough to catch American Ronnie Baker in lane seven as he stormed away to win in 9.90.
But Hughes' smile told the story as he finished second in 9.93 in a summer where he shares the European lead with France's Jimmy Vicaut, both men having run 9.91. Hughes said: "I am really happy with that. I am not technically a 100m runner and this helps my composure."
Imani-Lara Lansiquot has all but secured the third and final spot in the British women's 100m team for Berlin after a blistering run in a final won by Jamaica's double Olympic champion Shelly-Ann Fraser-Pryce in 10.98. Lansiquot was fifth in 11.11, breaking her personal best of 11.17, her time putting her joint sixth on the all-time British lists.
In the long jump, Shara Proctor chose the right time to produce a season's best performance as she defeated European leader and teammate Lorraine Ugen. Proctor had a superb series, with 6.82m, 6.80m and 6.87m building towards her fourth round 6.91m which brought victory. Ugen having only two legal efforts, the first of 6.68m before her last of 6.88m to take second spot.
Katarina Johnson-Thompson, who will chase heptathlon medals in Berlin - but not before she competes in tomorrow’s high jump - was fifth with a season's best of 6.70m from round three.
Lavillenie edges out Duplantis in the pole vault
The pole vault in Berlin could well become a duel between France's Renaud Lavillenie, who is seeking his fourth title, and Sweden's Armand Duplantis, the newly crowned World U20 champion.
Today Lavillenie edged ahead of Duplantis but they had to settle for second and third respectively as America's world champion Sam Kendricks won with 5.92m. Lavillenie and Duplantis both cleared 5.86m with the world record-holder, who was wearing the French football kit, finishing second on countback.
The programme started with a world best in the 3000m race walk for Tom Bosworth who clocked 10:43.84 to smash the long-standing mark of 10:47.11 set by Giovanni De Benedictis in 1990.
Bosworth won the Commonwealth silver medal in the 20km race walk in April and he is aiming for another podium finish at the European Championships in Berlin next month. “That’s a big confidence boost because we used the indoor season to boost me for the Gold Coast and I came home with a silver medal there. We’re trying to replicate that a little bit and these shorter races get the legs going,” he said.
