Dina Asher-Smith claimed her third medal at the World Championships, as she took silver in the women's 4x100m on the penultimate day in Doha.
Asher-Smith, Asha Philip, Ashleigh Nelson and Daryll Neita produced a season’s best time of 41.85s, just 0.08 seconds outside of the British record, to clinch 4x100m silver behind Jamaica, while the USA completed the podium.
Imani-Lara Lansiquot was due to run in the final but had to pull out with an injury during the warm up and, despite a last-minute change, Asher-Smith believed it was a demonstration of the understanding between the team.
“I think we all handled the pressure between us which is testimony to how much experience we have got as a squad,” Asher-Smith said.
“We almost ran a PB without practicing any of the changes in the warm-up area. It's been a good champs but obviously it's a team event.”
Nelson, who was particularly proud of the achievement, added: “Yesterday I was laughing and today I'm crying because it’s my first time running real in a champs since 2014, it means a lot to me, my coach and my family.”
Defending champions in the men’s 4x100m, Adam Gemili, Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake gave a good defence of their title but were beaten to the line by the USA.
The quartet produced a British and European record time of 37.36 seconds to claim the silver medal while Japan rounded out the top three.
Hughes injured himself during the final while running the second leg but carried on and was delighted to help the squad win a medal.
“Tonight I came out here and gave it my very best regardless. I think I strained my hamstring maybe,” Hughes said.
“I pulled it just before I handed over the baton but I knew I had to give it to Richard regardless because I wanted the guys to get a medal.
“I did my best and the guys came away with a medal. I'm happy, we're going back home with something around our neck.”
Anchor leg runner Mitchell-Blake trusts this silver medal will spur the squad to perform better in Tokyo.
"Phenomenal effort by the guys,” Mitchell-Blake added. “I'm proud of the boys. It gives us fuel for the fire for next year. Let's enjoy the moment right now though."
Laura Muir missed out on the podium in the 1500m, fading in the last 100m to fifth – although she did secure a season’s best time of 3:55.76.
However, after missing a few months on the season with a calf injury, the European Champion was amazed at her performance, which bodes well for 2020.
“I don’t know what to say, I was fifth in 3:55,” Muir said. “I just tried to cover the moves the as best I can. I think I lost a gear in the last 100 but to run 3:55 when I have missed so much training, I am just speechless but I am so proud of myself.
“I clocked it at 800m that it was fast, I expected people to die a bit but they must have kept the pace fast or faster.
“I could not have asked more of myself to do that. If I can run that sort of time off the minor training I’ve done, if I’m 100% fit, I can be confident going into next year.”
