Katie Ledecky touched the wall far ahead of everyone else at the U.S. swimming trials.

No surprise there.

But she was taken aback by the time. It wasn’t as fast as expected, raising the stakes for an expected showdown in Tokyo with the Aussie Terminator.

Ledecky earned a trip to her third Olympics with a never-in-doubt victory in the women’s 400-meter freestyle Monday night.

She was a good five body lengths ahead of runner-up Paige Madden, touching the wall in 4 minutes, 1.27 seconds.

But the winning time was far off Ledecky’s world record of 3:56.46, which she set almost five years ago at the Rio Olympics.

Another time on everyone’s mind: Ariarne Titmus won the 400 free at the Australian trials on Sunday with the second-fastest performance in history — 3:56.90.

Ledecky wasn’t close to Titmus’ performance, either.

“Very much a blur,” Ledecky said. “I thought I could go a little faster than that, so I’m a little surprised. But I’ll take it for now.”

Titmus, a 20-year-old known as “The Terminator,” has made it clear that she’s not intimidated by Ledecky’s longtime dominance in the distance events.
