Kent’s Dina Asher-Smith says she remains unfazed by her Olympic rivals after winning the British 100m title.

The 25-year-old from Orpington took the crown in 10.97 seconds at the British Athletics Championships in Manchester.

World 200m champion Asher-Smith had earlier set a new championship record with a dominant run of 10.91 seconds in the semi-final.

She goes to the Tokyo Games next month with 100m favourite Shelly-Ann Fraser-Pryce, who earlier this month set a world-leading 10.63 seconds and won the Jamaica Olympic trials in 10.71 seconds on Friday.

Asher-Smith said: “I’m in great shape, I know we all run in different continents and different conditions but when you all meet that’s what really matters.

“It (seeing other races) does give you indicators of where you are and what you can do but the true test is when you’re all together and what you perform like under the circumstances.

“I have faster in me. I’m in good shape. I’m a championship performer.”

The trackside timer initially clocked her final run at 10.71 seconds – a new British record – but was quickly changed to her official time.

“There are a few things I did wrong so when I crossed the line I was a bit like, ‘wow, okay,” said Asher-Smith.

“Maybe I can go so much faster because that wasn’t the perfect race, so I’m not entirely surprised to see the clock was not 10.71 but a win is a win at the Olympic trials.”

Asha Philip and Daryll Neita were second and third respectively but Asher-Smith underlined her dominance over her British rivals ahead of the start of the Olympics next month.
