Sophie Hahn added a second Paralympic medal to her impressive collection, but she had to settle for silver in the 4x100m relay.
The 19-year-old, who has cerebral palsy, was hoping to win a second gold after becoming the T38 100m champion six days earlier.
But the GB team were pipped by China in the women’s relay for T35 to T38 category runners.
The British quartet won the relay gold at the world championships in Doha last October, and this time set a new British record in Rio as Hahn anchored the team of Kadeena Cox, Maria Lyle and Georgina Hermitage to a time of 51.07secs.
But the Chinese were in impressive form to take the win in a world record time of 50.81secs.
Despite the unaccustomed second place, former Brooksby Melton College student Hahn was satisfied with her week in Brazil.
And she already has her sights set on avenging the result at the World Championships, in London, next summer.
“I’m just so delighted – it has been an amazing Games,” she said. “These girls are incredible and we are very lucky to be representing our country.
“Hopefully we have done everyone proud and we can come away with the gold next year. I’m looking forward to experiencing that home crowd spirit.
“China put up a fantastic time, I wanted to catch them but there’s always next year in London and we want to do better then.”
