Been watching this - probably more people in the local pub than actually in the stadium in Doha (an omen for the 2022 World Cup!?) Dina Asher Smith is a star of the future - a sliver in the 100m in a national record/personal best time at the age of 23. Only beaten by a true legend of the event in Fraser Pryce. They had a mixed 4x400m relay which like in swimming seems to be the vogue these days.
