Jamaica’s Adelle Tracey and Natoya Goule-Toppin finished third and ninth respectively in the women’s 800 metres at the Wanda Diamond League in Zurich, Switzerland on Thursday.

With none of the medallists from the World Athletic Championships in Budapest present, the event was left for the pickings, and it was Great Britain’s Laura Muir that proved best of the lot on the day, as the Jamaicans produced contrasting performances in their bid.

Muir, who assumed the lead at the 200m mark, left the field in her wake, as she went on to win in 1:57.71, ahead of Australia’s Catriona Bisset (1:58.77) and the fast-finishing Tracey (1:59.05), who left it late.

The front-running Goule-Toppin, who took the lead at the bell, faded into ninth in 2:00.10.
