Summary

Isaac Makwala (Botswana) had qualified for the final, but was barred from competing as he was under quarantine due to the norovirus outbreak in one of the athletes' hotels. ^[2] Steven Gardiner (Bahamas) started fastest, with Wayde van Niekerk (South Africa) equal to him by about 200 metres, and going on to build a lead through the final turn. Van Niekerk had time to slow down, winning comfortably ahead of Gardiner, with Abdalelah Haroun (Qatar) finishing quickly from dead last off the turn to claim bronze. ^[3]
