Dina Asher-Smith (16/1 100m Gold Medal) says she has “another level” ahead of her 100m semi-final appearance at Tokyo 2020.
The 25-year-old – who is the fastest British woman in history – did just enough in her heat after setting a time of 11.07.
She qualifies as the 11th fastest from the heats and will be up against some very stiff competition in Saturday’s semis before she, hopefully, reaches the final, which takes place at 13:50.
Asher-Smith, who is the reigning world 200m champion, says she can improve further.
“It felt good to be out here and to finally get going, and it’s just great to finally get my Olympics underway,” said the Briton, whose season’s best in the 100m is 10.91.
“I was just thinking about making it through to the next round safely, at the same time as knowing I’ve got another level to give.
“I am really happy. And I do have another level – of course I do, it’s an Olympics.”
Winning a gold medal will be very difficult for Asher-Smith, as she is likely to be up against Jamaican world record holder Shelly-Ann Fraser-Pryce (10/11 fav), who picked up gold in 2008 and 2012.
Elaine Thompson-Herah (15/8) is also a contender but Nigerian Blessing Okagbare is out after failing a drugs test.
Elsewhere, British trio Jemma Reekie, Keely Hodgkinson, and Alex Bell are competing in Saturday’s 800m semi-finals after coming through their heats (Gold medal – Reekie 12/1, Hodgkinson 20/1, Bell 100/1).
Reekie was one of just two athletes to run her semi in under two minutes while Hodgkinson is the current European indoor champion.
And, Team GB will also compete in the new 4×400 mixed relay final although it looks a tall order to bring home a medal.
