Kristal Awuah, who won World Junior bronze over 100m in 2018, win the first heat in 11.58 seconds.
Nicola Caygill is second in a personal best of 11.82 seconds.
First up are the early stages of the 100m, the finals of which will be
contested shortly after 20:00 BST tonight.
In the womens’ event
we have two of the bright young things of British sprinting in 22-year-old
Imani Lansiquot (the fastest Briton this year in 11.16) and 18-year-old Amy
Hunt, who is a junior world record holder over 200m and has a personal best of 11.31 seconds over the shorter distance.
Dina Asher-Smith? The world champion has been keeping a profile lower than a limbo-ing python this season. Her only outing so far has been a 150m race at an open meeting hosted by her club Blackheath & Bromley. She is not on the startline in Manchester.
British heptathlon world champion Katarina Johnson-Thompson has just finished fourth in the 100m hurdles at the Diamond League meeting in Brussels.
The 27-year-old ran a seasons-best time of 13.57 seconds. Belgium’s Anne Zagre won in 13.21 seconds.
