Summer McIntosh swam the fourth-fastest 400m individual medley in history on Friday, capping a year that already included world titles, Commonwealth Games titles and a victory over Katie Ledecky.

McIntosh, a 16-year-old Canadian whose mom swam at the 1984 Los Angeles Olympics, won the 400m IM in 4 minutes, 28.61 seconds at the U.S. Open in Greensboro, N.C. She prevailed by a Ledecky-like 13.24 seconds, breaking her own national record that was previously the fourth-fastest time in history.

“It’s still pretty early in the season, so I didn’t really know what to expect going into it,” she said on Peacock.

The only two women who ever went faster in the event known as the decathlon of swimming are Olympic gold medalists: Hungary’s Katinka Hosszu (world record 4:26.36 and 4:28.58) and China’s Ye Shiwen (4:28.43).

McIntosh has come a long way in a short time. Three years ago, she put all her eggs in the 1500m freestyle basket, thinking it was her best shot to merely qualify for the Tokyo Games in 2020. The one-year Olympic postponement was a blessing.

The rapidly improving McIntosh swam three individual events in Tokyo with a top finish of fourth in the 400m free, just missing becoming the youngest swimming medalist since 1996. She then told her coach she wanted to become an IMer.

At this past June’s world championships, McIntosh won two of the most grueling events — 400m IM and 200m butterfly — to become the youngest individual world champion since 2011. She also took silver to Ledecky in the 400m free, an event in which she later beat Ledecky in a short-course meet (25-meter pool rather than the 50-meter pool used for the Olympics).

A month after worlds, McIntosh swept the IMs at the Commonwealth Games, where she broke more world junior records and again took second in the 400m free (this time to Olympic champ and world record holder Ariarne Titmus of Australia).

McIntosh, who turned professional last year, now trains full-time in Sarasota, Florida, where she rents a house with her mom, Jill Horstead, who was ninth in the 200m fly at the 1984 Olympics (McIntosh, whose passions include the Kardashians and plants from Target, has seen video of her mom winning the B final at those Games). They’re a three-hour drive down Interstate 75 from Ledecky’s base in Gainesville.
