Britain's Jemma Reekie won the 800m at the World Athletics Indoor Tour meeting in Lievin, France.
The victory comes a month before the World Athletics Indoor Championships in Glasgow where the 25-year-old Scot is targeting a medal.
She recorded a time of two minutes 0.40 seconds, with Benin's Noelie Yarigo second in 2:01:19 and Swiss Audrey Werro third with 2:01:43.
Reekie came second in the 800m in last week's tour event in Metz, France.
She told the BBC last September that it would "would be amazing" to start this year with a world indoor medal in March before she attempts to improve on her fourth-place finish at the Tokyo 2020 Olympics at this summer's Games in Paris.
