Summer McIntosh Breaks 400M Individual Medley World Record, Extends Historic Week | NBC Sports

Canadian swimmer Summer McIntosh broke her second world record this week, lowering the 400m individual medley mark on Saturday.

McIntosh, a 16-year-old who trains in Sarasota, Florida, clocked 4 minutes, 25.87 seconds at the Canadian Championships in Toronto.

She took down Hungarian Katinka Hosszu‘s world record of 4:26.36 from the 2016 Rio Olympics. Before Saturday, McIntosh had the fourth-fastest time in history of 4:28.61.

“It’s always nice to set world records,” McIntosh said.

On Tuesday, McIntosh broke the 400m freestyle world record, becoming the youngest swimmer to break a world record in an individual Olympic event since Katie Ledecky in 2013.
