Six months ago, Orpington athlete Dina Asher-Smith could barely even walk after breaking her foot - now she has a World Championships silver medal around her neck after a remarkable comeback.

It seemed like 21year-old Ms Asher-Smith’s season was in tatters when she fractured her navicular bone in February.

But the plucky 21-year-old opted to have a screw put into her foot in the hope that she might be able to compete.

She went on to win a silver medal in the women's 4x100m Relay with Asha Philip, Desiree Henry and Daryll Neita on Saturday (August 12), after finishing fourth in the individual 200m event by running a blistering season's best 22.22 seconds.

The British team lost to the USA but beat the Jamaican team. They won bronze at the Rio Olympics last year and so the silver medal is a step up.

Ms Asher-Smith said: “I’m still in a dream phase, because I didn’t even know if I was going to be at the World Championships.”

“Suddenly, when I started running again, I was thinking maybe I could go and do the relay, and hopefully get a run.

“So to transform from that into getting a world silver, which is the highest medal we have ever won, is absolutely incredible.

“I’m still very much in a dream state - it just shows that you should never give up.

“I won my first world medal in Moscow, so I’m building up a little collection. We’ll have to wait and see when the gold is coming,” she added.

Ms Asher-Smith also came fourth in the 200m sprint with a season’s best time of 22.22 seconds.

After the race, she said: "I had no idea I could do that time. I was enjoying it, having fun and I got round the bend and I was like ‘I’m doing well’ but I’m a bend girl so I’m normally doing well on the bend.

“I got to 50m to go and I was ‘I’m still doing well, what’s this!?’ I got to 30m to go and then I saw her (Miller-Uibo) in the corner of my eye and I was like ‘damn’.

“I didn’t know I could do 22.2 so to do that, faster than I did in an Olympic year, I’m over the moon.

“There’s always ‘what ifs’ in everything. I lay with the cards I’m dealt. Fourth is the best I’ve ever finished. To finish fourth in a world final after having a broken foot is really good.”

On Twitter, Ms Asher-Smith said: “4th in the world over 200m with a huge SB of 22.22 and winning a world silver with the ladies!!! Over the moon and can't stop smiling.

"If this champs and year has taught me anything it's that anything is possible through hard work, self belief and trusting the process"

Ms Asher-Smith attended Newstead Wood School in Avebury Road and is the current British record holder for the 100m and 200m, making her Britain’s fastest woman.

After her success, Orpington 1st tweeted: "Congratulations, @dinaashersmith - Orpington is so proud of you!"

Her achievements include coming first in the 200m at the 2016 European Championships in Amsterdam. She also won gold in the 100m at the 2014 World Junior Championships in Oregon.

She is a member of the Blackheath and Bromley Harriers AC and has been competing for the club since 2007.

Pat Calnan, British league team manager at Blackheath and Bromley Harriers AC said: “To see someone progress from a talented schoolgirl to an international athlete is quite amazing and shows what can be done with hard work, talent, good coaching and family support.”

Asher-Smith was one of two medalist for Blackheath and Bromley Harriers, with Dartford sprinter Adam Gemili - who himself missed out on selection for the 200m after an injury ravaged season - claimed gold with the men's 4x100m relay team.

Mr Calnan said he was happy that Gemili had won a medal as he faced injuries in the run up to the championships.

He said: “It was a tremendous performance given it was the third fastest time ever and a British record.

"I’m very pleased for Adam as he had some injuries and so he didn’t compete as an individual in the championships.

“Everybody in the club is delighted by his performance at the championships. He is a great ambassador of the club and we are very proud of him.”
