Laura Muir bounced back from her Olympic disappointment by smashing her own British record by an astonishing two seconds with a brilliant 1500 metres victory at the Diamond League meeting in Paris.

After finishing seventh in the Olympic final, she underlined her class by delivering a last lap surge to obliterate a field that included Rio 2016 champion Faith Kipyegon and bronze medallist Jenny Simpson. Punching the air in delight, her time of 3:55.22 is the quickest in the world this year - just a month after she beat Kelly Holmes’ long-standing UK mark in London.

Muir is now second in the overall Diamond Race standings behind Kipyegon with one more appearance in Zurich on Thursday.

Meanwhile, Ruth Jebet of Bahrain broke the 3000m steeplechase world record with victory in 8:52.78 and Desiree Henry produced the third quickest 200m of all-time by a Briton with a time of 22.46 secs to finish second to Olympic silver medallist Dafne Schippers.
