The United States was favored, with the other medals expected to be contested by Jamica, the Bahamas, and Belgium, who ran three Borlée brothers. All four teams made the final, as expected. Isaac Makwala put Botswana into a surprising lead, with the US second on the first leg. Tony McQuay ran 43.5 on the second leg to move the US into the lead, which they would not relinquish. Botswana remained in a surprising second through three legs, but struggled on the final leg, and finished fifth. The US won gold with LaShawn Merritt running a 43.97 anchor as Jamaica took the silver medal and the Bahamas the bronze, narrowly beating out Belgium.
