Kent’s Dina Asher-Smith says her focus is now all on the run-up to the Olympics in 2020 after she confirmed an historic golden sprint treble at the European Championships in Berlin.

Asher-Smith, 22 from Orpington, guided Great Britain’s women’s 4x100m relay team to the title on the final night of the competition, overtaking three athletes in a devastating final leg to come home in a world-leading time of 41.88 seconds.

In leading home the team of Asha Philip, Imani Lanisquot and Bianca Williams, Asher-Smith added to the 100m and 200m titles she won earlier in the week, becoming the first British woman to secure the sprint treble at a major championships.

“I’m happy but it’s all about moving to Tokyo, you’ve got to use it and push yourself onto a platform for Doha and Tokyo and beyond,” Asher-Smith said.

“The British athletes have had the Commonwealths and Europeans this year, so we’ve had to peak.

“Half the American people aren’t even running. While it’s great for me this year it doesn’t forecast how the next two years are going to go.”

Later Great Britain secured top spot on the athletics medal table on a pulsating final night of the new multi-sport championships.

Scotland’s Laura Muir became the first British woman to win 1500m gold ahead of compatriot Laura Weightman, who took bronze.

Muir had never won a major outdoor competition going into the race but but settled in after a slow start and — supported by Weightman — made a brave break to split the field before holding on in the home straight.

Great Britain was also victorious in the men’s 4x100m relay with CJ Ujah, 100m champion Zharnell Hughes, Kent’s Adam Gemili and Harry Aikines-Aryeetey crossing the line in an impressive 37.80 seconds.

Elish McColgan won silver in the women’s 5000m to make it seven golds, five silvers and six bronze medals for Great Britain.
