SYNOPSIS
Can Britain's first female global sprint champion, Dina Asher-Smith, make more history with Olympic gold in the 200m final? Asher-Smith has gone from carrying the athletes' kit as a volunteer at the 2012 Olympics to becoming one of Britain's outstanding medal prospects in the sport. Her 2019 world title came in the absence of the brilliant Bahamian Shaunae Miller-Uibo, who prioritised the 400m in Doha. This time, it is expected that Miller-Uibo will give up her defence of the Olympic 400m title.
