# 2016 IAAF World Indoor Championships – Men's 400 metres

The men's 400 metres at the 2016 IAAF World Indoor Championships took place on March 18 and 19, 2016.
All eyes were on Bralon Taplin, who had run the three fastest times of the year, including a win in the semifinals. He led from the break, closely followed by defending champion Pavel Maslák. For 350 metres, Taplin maintained his lead, but Maslák made his move with just 50 metres to go. In a few strides, Taplin was overtaken. Further back, Abdalelah Haroun executed a similar move, overtaking Deon Lendore. Taplin, exhausted, faded quickly. Haroun made a strong push to close the gap on Maslák but fell just short, finishing second. Maslák won with a time of 45.44, while Haroun claimed silver and Lendore took bronze.
