The two dominant 400 metre runners over the last few years had been Grenadian Kirani James and American LaShawn Merritt. Merritt was Olympic gold medallist in 2008, and World Champion in 2009 and 2013, while James was 2011 World Champion and 2012 Olympic Champion. At the 2015 World Championships, both were upset by South African Wayde van Niekerk. The Rio Olympic final was expected to be a battle between the three, but most expected the battle to be between James and Merritt.
James and Merritt were in the first semi-final and pushed hard, James winning in 44.02 to Merritt’s 44.21. In the second semi van Niekerk trailed Trinidadian Machel Cedenio, who ran 44.39 to van Niekerk’s 44.45.
In the final, James and van Niekerk, running in lane eight, led on the first turn, but Merritt took the lead at 200 metres, passing in 20.4. On the final turn, van Niekerk powered ahead, reaching 300 metres in 31.0 to 31.2 for his two adversaries. Many thought he had gone too hard and would struggle on the run-in, but he never slowed, increasing his lead and finishing his gold medal run in a world record time of 43.03, with James second in 43.76, and Merritt taking bronze in 43.85. Cedenio finished fourth in a national record time of 44.01.
