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

Asher-Smith, 22, guided Great Britain's women's 4x100-meter relay team to the title on Sunday, 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 Lansiquot and Bianca Williams, Asher-Smith added to the 100-meter and 200-meter 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 multisport championships.

Scotland's Laura Muir became the first British woman to win 1,500-meter gold ahead of compatriot Laura Weightman, who took bronze.

Muir had never won a major outdoor competition going into the race 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 4x100-meter relay with CJ Ujah, 100-meter champion Zharnel Hughes, Adam Gemili and Harry Aikines-Aryeetey crossing the line in an impressive 37.80 seconds.

Eilish McColgan won silver in the women's 5,000 meters to make it seven golds, five silvers and six bronze medals for Great Britain.

In the same race, Israel's Lonah Salpeter suffered a disastrous loss when she celebrated what she thought was a silver medal a lap early.

Salpeter powered into second on the penultimate lap and raised her hands in triumph only to quickly realise the race had not yet finished. She ended up missing out on a medal.

Swedish teenager Armand Duplantis became the youngest ever European champion in a field event by winning the pole vault.

The 18-year-old surmounted a height of 6.05m on the way to the title.
