One of the autographs that Katie Ledecky signed in the summer of 2014 was for a 12-year-old Australian named Lani Pallister.
“Dream big!” Ledecky inscribed in a small spiral notebook, an image that for a time was Pallister’s screen saver.
Tonight, Pallister will dare to dream big.
The last session of the Pan Pacific Championships, the biggest meet of 2026 for Americans and Australians, features potentially the most seismic swim of the year. Coverage airs at 10 p.m. ET on Peacock and NBCSN from Irvine, California.
Pallister has a chance to become the first swimmer to beat Ledecky in an 800m freestyle championship final.
The 800m free is Ledecky’s favorite event, the one she took ownership of at the 2012 Olympics as a 15-year-old. That ignited a streak of winning it 13 consecutive years at each season’s biggest meet (save 2020, when COVID postponed the Olympics).
“Even in practice, if I’m doing 800s, I kind of tell myself that — I kind of have this fake rule that I don’t lose 800s,” Ledecky said at the 2025 World Championships, according to World Aquatics. “So whenever we’re doing 800s in practice, that’s when I really try to get up there with (training partner and Olympic gold medalist) Bobby (Finke), and I tell myself that.”
At those 2025 Worlds in Singapore, Pallister came the closest of anybody in history to Ledecky in a distance race at a major international meet.
She charged home in the 800m free final with the fastest last 50 meters, touching just 36 hundredths behind the American legend in an eight-minute race. Pallister took 4.86 seconds off her Australian record time.
“Getting the silver behind the greatest distance (swimmer) is wicked,” she said then, according to World Aquatics.
Swimming Australia
Pallister is the latest swimmer to shift from childhood Ledecky fan to a bona fide rival.
Fellow Australian Ariarne Titmus, then 15, marveled at Ledecky’s four-gold-medal performance during the 2016 Rio Olympics.
“I remember watching her races thinking, like, this chick is nuts,” Titmus said in 2020. “She’s just doing stuff that no one’s gonna get near.”
Three years later, Titmus ran down Ledecky in the last 50 meters of the 400m free at the 2019 World Championships. She became the first woman to beat Ledecky in a 400m in seven years, then did it again at the Olympics in 2021 and 2024 before retiring last year.
Titmus’ coach, Dean Boxall, famously shouted Ledecky’s name during practice as Arnie the Terminator swam laps.
Boxall now coaches Pallister, who was formerly coached by her mom, Janelle Elford, who at the 1988 Seoul Olympics swam the 400m free (fifth place) and 800m free (sixth).
“I’ve pretty much had the playbook to success for me,” Pallister said of her mom. “She’s done everything that I have just 32 years prior.”
Pallister remembers her mom being the medal presenter for Ledecky after the 800m free at the 2014 Pan Pacs in Gold Coast, Australia, where Ledecky broke that world record for the third of six times in her career.
Pallister also remembers attending the 2014 U.S. Championships — at the same Irvine pool as these Pan Pacs — and watching Ledecky break the 400m free world record for the first of three times.

Around the time Titmus was in awe over Ledecky’s dominant victories, a preteen in Toronto put a Ledecky quote on her bedroom wall.
Summer McIntosh said it was something along the lines of, “Every race is a sprint. Some are just longer than others.”
McIntosh went on in February 2024 to become the only woman to beat Ledecky in an 800m free at any level in the last 16 years, doing so at a local meet in Central Florida.
McIntosh also led the 800m free final at the 2025 Worlds through 700 meters before Ledecky and then Pallister passed her.
As McIntosh shifted her focus to shorter races in the last year, Pallister continued her emergence.
Last October, Pallister broke Ledecky’s world record in the short-course 800m free -- in a 25-meter pool, rather than the 50-meter pools used at major meets like the Olympics, worlds and Pan Pacs. Ledecky has rarely raced short course, but Pallister did take a sizable chunk off Ledecky’s record from 2022 (3.42 seconds).
Then this past Wednesday at Pan Pacs, Pallister came the closest of any woman to Ledecky in a championship 1500m free in 13 years — 2.53 seconds behind. That swim came two hours after Pallister won the 200m free over McIntosh.
“My quad and hip flexor starting almost cramping at 1,000 (meters), so it was kind of just survival mode,” Pallister said.
On Friday, Pallister earned her first career win over Ledecky, doing so in the 400m free. It wasn’t surprising at the shorter distance, but it did add anticipation for Saturday’s 800m.

“HOPE ISN’T A STRATEGY” is tattooed on Pallister’s left arm.
She got it after a trying 2021 — she had heart surgery for supraventricular tachycardia (SVT, which can cause an irregular or elevated heartbeat), dealt with an eating disorder and missed the Tokyo Olympic team.
“I kind of just hoped everything would work itself out and sort itself out in the long run,” she said Friday. “It wasn’t until I kind of sat down, spoke to my psych and the network around me and actually talked about all the things that had kind of gone wrong that it’s not a strategy to just kind of coast through life. I think that year taught me a lot in resilience, and it’s definitely made me who I am now.”
