The Team GB quartet of Dina Asher-Smith, Asha Philip, Desiree Henry and Daryll Neita claimed Britain’s first Olympic medal in the women’s 4x100m relay for 32 years after storming to bronze at Rio 2016.

In perfect conditions at the Olympic Stadium, Team GB’s sprinters got off to a fast start through Philip and displayed slick baton changes throughout.

Asher-Smith ran the third leg and handed over to Lewisham-based Neita on the anchor leg who powered them across the line in a new British record of 41.77 seconds.

The run secured Team GB a podium spot alongside winners USA and silver medallists Jamaica and the first medal for the nation in the 4x100m relay at the Olympics since Los Angeles 1984.

Orpington sprinter Asher-Smith said: “We have worked so unbelievably hard as a team. We have had relay practices since January to get it right.

“This means an awful lot because not only have we worked hard to get faster as individuals, we have bonded and worked hard as a team.

“To be able to come out here when the pressure is on and it really matters and deliver the goods is absolutely incredible. I am so proud of the girls.”

Asher-Smith, who runs for Blackheath and Bromley Harriers, ran a season’s best to finish fifth in the women’s 200m final.

She recorded a time of 22.31 as Jamaica’s Elaine Thompson completed an Olympics double.

Asher-Smith had set her sights on a personal best but insisted she was pleased to mix it with the best athletes in the world on the biggest stage of them all.

She said: “I was quite happy with that, considering my rounds didn’t go exactly as my coach and I had planned. I pulled a fifth back and was mixing it until near the end. I was really happy and I’ll take that.

“Obviously I want to run a personal best every time and get faster and faster, but I don’t think anyone out there ran one, it wasn’t one of those races.”

Asher-Smith, 20, holds the British records for both sprint distances and is the reigning European Champion at 200m.

The former Newstead Wood School pupil admits her self-belief has improved this year and says she hopes to take her form into next season.

“This year I’ve learned not to freak out when I see other people go like that because it’s what they’re going to do,” she added.

“This year I’ve believed a bit more. Although I got exactly the same place [as last year] I’ll go again next year and the year after that.

“Next year I’m going to remember to relax for the last bit. As soon as you start thinking about catching the others you start thinking about having the wrong mentality.”
