The British quartet of Dina Asher-Smith, Imani Lansiquot, Amy Hunt and Daryll Neita secured women’s 4×100 metres silver at the Stade de France.
Team GB won bronze in the same event for the last two Olympics and were one of the favourites on Friday night.
They looked like they might be on course to secure gold before a messy handover between Hunt and anchor Neita cost them time.
The United States’ Sha’Carri Richardson took full advantage to pip the Brits to the line by seven one hundredths of a second in 41.78.
The British men followed the women’s silver immediately with 4×100 metres bronze.
Zharnel Hughes, who had pulled out of the men’s individual 200 metres due to hamstring tightness, returned to anchor a line-up also featuring Jeremiah Azu, Louie Hinchliffe and Nethaneel Mitchell-Blake.
It was a season’s best for the British men’s quartet in 37.61, who finished behind Canada, champions in 37.50, and South Africa, who claimed silver.
