Men's 400m IM - Final



The United States is off an running in the best possible way.

The Americans swept gold and sliver, with Chase Kalisz, the Rio 2016 silver medalist, executing arguably the best race of his career to clinch gold and Jay Litherland closing hard in the final 50 meters to complete the 1-2 finish.

Kalisz turned at the 300-mark nearly 2.5 seconds ahead of top-seeded Kiwi Lewis Clareburt, who usually closes well. On commentary at that moment, Michael Phelps, a longtime friend and former training partner of Kalisz's, called it "The closest 400 IM I think I've ever seen."

But that comment would prove to be premature, as Kalisz won by over three-quarters of a second.

"It mean's the word," Kalisz said through the pain of lactic acid buildup. "This was the last thing I really wanted to accomplish in my swimming career. This is something that's been a dream of mine for as long as I can remember." 

Litherland, who was born in Osaka, Japan, was behind significantly heading into the final 50, but closed exceptionally well to take silver
