Rome - Britain's Dina Asher-Smith will be looking to continue her astonishing start to the season and build towards the world championships in Doha next September when she takes to the track for the women's 100 metres at the Diamond League meeting in Rome on Thursday.
Asher-Smith, the triple European champion, underlined her world title ambitions by leaving the reigning Olympic and world champions in her wake with a stunning 200m victory in Stockholm last week.

"At the same time I have trained very well, continuously, without a hitch, with a lot of recovery to cope with this extended season," he added.In the 400m hurdles American Raj Benjamin, who equalled Edwin Moses’ historic 47.02 career best last year, will be in the spotlight.Benjamin ran his Diamond League race in Shanghai, where he set the second best performance of his career with 47.80.
