The first round consisted of nine heats, with qualification for the first two in each heat and the sixth fastest losers. However, due to a dead heat for second in Heat 7, three runners qualified automatically, and the fastest losers places were reduced to five. Adam Gemili was the fastest qualifier from the first round, at 10.15 seconds.
Three semi-finals were held, with automatic qualification restricted to the first two finishers in each heat, and the next two fastest athletes across the three semi-finals. Kemar Bailey-Cole was the fastest qualifier in 10.00 seconds.
