Karsten Warholm came to Stockholm Stadium to challenge the world record of 46.78 by Kevin Young. The Norwegian kept his promise - he gave the iron.

Warholm flew forward under 400 meters hurdles and finished in a time of 46.87. It is a new European record, and only nine seconds behind Young's world record.

Shivers. It is standing fur all over the body, says SVT Sports expert Kajsa Bergqvist.

- He's absolutely incredible. He is in a class of his own, which race he does.

Young set the world record during the 1992 Olympics.

Second in today's race was Wilfried Happio, he ran 49.14. The Swede Carl Bengtström ran 50.21, which is the best year for him.
