RIO DE JANEIRO >> Katinka Hosszu finally claimed her first Olympic medal — and set a world record for good measure.

The Hungarian star, known as “The Iron Lady” for her grueling schedule, crushed the former mark in the women’s 400-meter individual medley Saturday night at the Rio Games. She led all the way and touched in 4 minutes, 26.36 seconds, easily eclipsing the record of 4:28.43 held by China’s Ye Shiwen.

Hosszu had time to turn toward the scoreboard and savor her triumph before Maya DiRado of the United States touched in 4:31.15 to take the silver medal. Mireia Belmonte Garcia of Spain claimed the bronze in 4:32.39.

This triumph was especially sweet for Hosszu, who had captured nine medals — including five golds — at the world championships but never won an Olympic medal.

Now, she has the best one of all.

Elizabeth Beisel of the U.S., the silver medalist at the 2012 London Games, finished sixth.
