Summer McIntosh Ends Katie Ledecky's 11-Year U.S. Winning Streak in 400m Freestyle

The Canadian teenager won the race at the U.S. Open championships with a meet record time, marking Ledecky's first loss in this event on American soil in over a decade.

Canadian teenager Summer McIntosh defeated Katie Ledecky in the 400-meter freestyle race at the U.S. Open championships, marking Ledecky's first loss in this event on American soil in 11 years.
McIntosh won with a meet record time of 3 minutes, 59.42 seconds, beating Ledecky by nearly 3 seconds.
This is not the first time McIntosh has bested Ledecky; in March, she ended Ledecky's nine-year U.S. win streak in the 200 freestyle.
McIntosh previously held the 400 free world record for three months before it was reclaimed by Australia's Ariarne Titmus.
Ledecky, who holds two world records in 800 meter and 1,500 meter freestyle, remains unbeaten domestically in those two races for the past 13 years.
