Another European record for Karsten Warholm while Thomas Barr sixth in Zurich

Karsten Warholm has smashed the European 400m hurdles record again, recording the second-fastest time ever as Thomas Barr finished sixth in the Diamond League Final at the Weltklasse Zurich meeting.

Warholm surged to victory in a stunning 46.92 seconds, obliterating the 47.12 mark the 20-year-old Norwegian clocked in London five weeks ago, having first broken the European record with a 47.33 at the Bislett Games in Oslo in June.
