BUDAPEST, Hungary – Katie Ledecky has extended her record haul of medals from the world championships to 21, two more than any other female swimmer managed before.

All but three of them are gold.

Ledecky, 25, claimed her 18th gold at a worlds on Wednesday as the United States won the women’s 4x200 freestyle relay final, clocking the fastest split – 1:53.67 – to help the Americans triumph in a championship record 7:41.45.

Claire Weinstein, Leah Smith, Ledecky and Bella Sims finished 2.41 seconds ahead of the Australian team and 3.31 ahead of the Canadians.

“It’s awesome,” Ledecky said. “It’s so easy to get up for these relays and just not think and go. I had so much trust in these three and I think that we’re always counted out and we always deliver, so I am so proud of this group.”

Ledecky had already won gold medals in the 1,500 freestyle Monday and 400 freestyle Saturday to add to the 15 gold she had coming into the competition in Budapest.

Her 21 medals at a worlds are two more than compatriot Natalie Coughlin managed (seven gold, seven silver, five bronze) between 2001 and 2013.
