Summary
Kirani James was the Olympic champion in 2012 and was in good form before the competition with a run of 44.08 seconds placing him second on the global rankings. The 2008 Olympic champion LaShawn Merritt topped the lists for the season as the only man under 44 seconds. Wayde van Niekerk ranked third and was the 2015 World Championships winner. At that competition the trio had all run under 44 seconds for medals (a first for the sport) and were the principal challengers to the Olympic title. Two younger athletes, Baboloki Thebe and Machel Cedenio, were the next fastest athletes to enter. James was the fastest in the first round with 44.93 and Cedenio was the other heat winner under 45 seconds. The 2016 World Indoor Champion Pavel Maslák, David Verburg and Rafał Omelko qualified as fastest losers. Former European champions Martyn Rooney and Kevin Borlée were eliminated.
In the semi-finals, James had a season's best time of 44.02 to win the round nearly two tenths ahead of Merritt. Cedenio won the 2nd semi final ahead with van Niekerk second. Bralon Taplin won the third semi final. Fastest loser qualifiers Karabo Sibanda, Matthew Hudson-Smith and Ali Khamis all set personal bests.
In the final, the three favorites James, van Niekerk and Merritt were drawn in lanes 6, 8 and 5 respectively and led from the start. By the end of the turn, van Niekerk had a clear 2 metre lead, Merritt just slightly ahead of James who had closed the gap during the turn. Cedenio was another four metres back, with Taplin another metre back. In the home straight van Niekerk increased his lead while James overtook Merritt, finishing 2nd and 3rd. Cedenio was 4th, Taplin faded and in lane 1, eighteen year-old Karabo Sibanda finished fifth.
Van Niekerk set a new world record of 43.03 seconds, beating Michael Johnson’s previous record set at the 1999 World Championships by 0.15 seconds. No other athlete had won a major championship from lane 8. Johnson was in the stadium, working in the British commentary booth.
Cedenio set the national record for Trinidad and Tobago and Ali Khamis in sixth set the national record for Bahrain.
