Bethan Morley put in a storming last leg to earn bronze for Great Britain in the mixed relay at the World Athletics Cross Country Championships in Belgrade, Serbia.
The British quartet were down in eighth at the halfway point with Kenya and Ethiopia well in front.
But Adam Fogg made up ground on the third leg, moving GB up to fourth.
Morley overhauled then third-placed American Katie Izzo on the final leg, giving GB a finish time of 23 minutes.
The British team were eight seconds clear of fourth-placed Morocco.
It is Great Britain’s first medal at the Championships since the junior women won bronze in Bydgoszcz in 2013
Kenya took victory in 22:15, 28secs ahead of Ethiopia whose final runner Birri Abera lost her shoe on the final changeover.
“We thought it might be possible to win a medal today,” said Fogg. “But we knew we were going to have to have a really good day and thankfully we pulled it together and got it done.
“I think that is more than we could have asked for.”
Morley added: “The American girl was in my sights early on, but I had to remain calm and not go off too quickly.
“Coming down the final ramp into the home straight I was just thinking: ‘Oh my god, I am going to be a world medallist, you’ve got to keep it going!’
“We thought on a very good day we could get a medal, and look, we had a very good day.”
