Great Britain's Zharnel Hughes will begin his bid for World Athletics Championships glory in Doha on Friday as the competition begins.
The 100m heats also contain the controversial Olympic champion Justin Gatlin and the favourite, fellow American Christian Coleman, who has come under scrutiny in the build-up due to missed drugs tests.
Elsewhere Britain's Holly Bradshaw will begin her campaign in the women's high jump, while her team-mate Morgan Lake will start qualifying for the women's high jump final.
The women's marathon will go ahead at midnight, despite the safety concerns over the intense heat and humidity in Qatar this evening.
