A big night for Irish athletics
Rhasidat Adeleke has quickly established herself as one of the top sprinting stars in the world since turning professional after a brilliant colleagiate career.
The Tallaght runner holds national records over 60m, 100m and 200m, but her speciality is the 400m, in which her personal best of 49.07 puts her in contention for a medal.
But the 21-year-old won't be looking beyond tonight's semi-final and a quality field at the Stade de France.
Adeleke is set to run in the first of the semi-finals. Stay with us for all the action....
