Katie Ledecky is showing off Olympic form at this week’s Tyr Pro Meet, the biggest stage she’s been on since winning two gold medals and four medals overall in Paris last summer.

The legendary swimmer posted the second-fastest 400-meter freestyle time of her career on Thursday when she outlasted Canada’s Summer McIntosh at Fort Lauderdale, Fla.

Ledecky, 28, passed McIntosh in the final 50 meters to win in 3 minutes, 56.81 seconds, just shy of her American record 3:56.46 set when she won the event at the 2016 Olympics at Rio de Janeiro.

“I don’t know if I ever thought I would be 3:56 again,” Ledecky said of the time that rates as seventh best in history. “All the credit to Summer. It’s always a great race when we’re next to each other. I’m just really happy with all the work that I’ve put in to get to this point.”

McIntosh finished in 3:58.28 while American Claire Weinstein was third in 4:01.26.

The result comes one day after Ledecky turned in a spectacular performance in the 1,500-meter freestyle.

Ledecky recorded the second-fast 1500 free time in history by finishing in 15:24.51, nearly 40 seconds ahead of second-place finisher Jillian Cox of the United States.

Ledecky owns the 22 fastest 1,500 free times in history, topped by a 15:20.48 in 2018.

The meet runs through Saturday.
