Newark's Amy Hunt breaks Dina Asher-Smith’s British under-20 record over 200m at the Mannheim Junior Gala in Germany

Amy Hunt set a new British record in the 200m sprint as she stormed to a stunning win at the Mannheim Junior Gala in Germany.

Hunt, 17, of Newark, crossed the line in 22-24 to break Dina Asher-Smith’s British under-20 record over 200m, which also ranked her as the third fastest time British woman over 200m of all time.

The time puts her joint 73rd on the all time senior women’s list ­— 0-9 seconds behind world record holder Florence Griffith-Joyner, who finished in 21-34 at the Seoul Olympic Games in 1988.

Hunt said: “I am still utterly in shock and haven’t quite processed what happened yet.

“I was really excited going into the race, but my main priority was to enjoy the race and gain experience, so I was completely mind-blown when I saw the time.

“The reaction to the run has been insane, but I know I’ve got to keep my feet on the ground and hopefully there’s even bigger things to come.”

Hunt travelled to Mannheim with a small contingency of GB Juniors, and competed against athletes from 18 other countries.

In 36° heat, Hunt opened her tournament in the under-20 4x100m.

Hunt’s team earned a new season’s best performance of 44-29 seconds, and with the Newark runner on second leg, she made up ground to overtake the early frontrunners, which set-up an impressive team performance and win.

The European under-20 leader in the 100m and 200m said she was pleased with her run and was excited at the prospect of the 4x100m final and the individual 200m the following day.

In the final, the GB relay team put in another strong performance to take gold, but there was no time to celebrate as Hunt rushed to start her preparations in the individual 200m race.

The GB junior got off to a flyer in the 200m, powering around the bend to the straight, creating a sizeable lead on the rest of the field.

Hunt continued to ruthlessly power down the straight to finish in 22-42 to take the win.

Claire Hunt, Amy’s mother, said: “The crowd reacted with great excitement to this as the time was so quick.

“Amy could not quite believe how the race went and the super quick time.”

To ratify the world record performance, Hunt had to go through anti-doping tests to ensure there was no controversy as to the performance, before flying home.

On a high from her best, Hunt said her focus has shifted to the European Junior Championships in Boras, Sweden on July 18 to 21.

“This is the main focus for the year,” she said.
