She started running to lose five pounds gained on a vacation.
Four decades later, Jeannie Rice is holding two marathon world records, has logged over 130 races, and just became the subject of a landmark scientific study that left researchers genuinely stunned.
At 77 years old, her aerobic capacity rivals that of a healthy 25-year-old woman — a finding so extraordinary it made headlines across the global running community.
Her secret has nothing to do with elite genetics or cutting-edge training technology, and everything to do with habits so simple they almost feel like a dare.

From Five Unwanted Pounds to Marathon World Records
Rice was born in South Korea in 1948, moved to Mentor, Ohio as a teenager to study nursing, and later built a career in real estate. She was 35 years old when she laced up her first pair of running shoes — and her motivation was spectacularly unambitious.
I was hoping to drop the five pounds I had gained on a recent vacation.
That was the plan. Lose a little weight, move on.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Instead, she never stopped. Rice went on to complete more than 130 marathons, earn the World Marathon Majors six-star finisher status, and regularly beat every male runner in her age group. She didn’t start setting world records until she turned 70 — which raises an obvious question: what took so long?
She simply hadn’t aged into the right division yet.
The Records That Rewrote the Rulebook
At the 2019 Berlin Marathon, Rice clocked 3:24:48 — a W70 age-group world record that still hasn’t been touched. Then, three days after her 75th birthday, she crossed the Boston Marathon finish line in 3:33:15 to claim the W75 world record as well.
And it’s not just the marathon. She holds world age-group records across the 1,500 meters, 5,000 meters, and 10,000 meters — a range of distances that elite athletes half her age rarely master simultaneously.
She trains without a coach. When asked how she plans to top a world record, her answer was characteristically blunt.
How do you get faster than a world record?
The Science That Stopped Researchers in Their Tracks
In April 2024, Rice traveled to Loughborough University in Britain for a comprehensive physiological assessment. What the lab found was unlike anything previously recorded for a woman her age.

Her VO2 max — the gold-standard measure of aerobic fitness — came in at 47.8. Published in a 2025 case report in the Journal of Applied Physiology, that figure represents the highest ever recorded for a woman aged 75 or older.
For context, 47.8 is the average score for a healthy woman in her mid-twenties.
Her max heart rate registered at 180 beats per minute — again, numbers that belong in a college athletics lab, not a 77-year-old’s medical chart. Fascinatingly, her running economy tested as completely unremarkable. She isn’t naturally efficient.
She’s just relentlessly powerful.
The Five Habits Behind One of Sport’s Most Extraordinary Bodies
Strip away the records and the research papers, and Rice’s daily routine is almost shockingly ordinary. Here’s exactly what she does — and what any runner can borrow from her playbook.
She Hasn’t Cut Back Her Mileage — Not Once
Rice runs approximately 50 miles every week, year-round. When a major marathon is approaching, that climbs toward 60 miles. Each training block includes four or five 20-mile long runs, and that structure hasn’t changed in four decades.

- Comfortable grip that makes high-rep workouts easier to handle
A lot of other runners decrease their training as they get older. But I haven’t done that.
That single decision may be the most important one she’s ever made.
She Lifts Weights — But Only From the Waist Up
Twice a week, Rice hits the gym for light upper-body strength training. Her legs, she reasons, already have all the stimulus they need from 50 miles of weekly running.
She also rows, aqua-jogs, downhill skis, and plays golf. Cross-training, in her world, is simply anything that isn’t another run.
Her Diet Looks Like a Korean Grandmother’s Meal Plan
Rice has been a pescetarian her entire life. Her favorite meal is a salad with roasted salmon — the kind of food she grew up eating in South Korea.
She avoids sweets, drinks wine occasionally, and has maintained a weight between 100 and 103 pounds for 40 years without ever counting a calorie or tracking a macro. No trendy protocols. No supplements. Just whole food.
She Trains Alone but Never Runs Alone
Rice has never worked with a coach. She joined the North Cleveland Runners Club 41 years ago and absorbed nearly everything she knows from running alongside its members.

- Full-body training with one weight using swings, squats, and presses

Her current training partners are women in their mid-to-late 50s — roughly two decades her junior. She keeps up just fine.
They say I’m inspiring them. I say that they’re keeping me young. It’s good for all of us.
She Simply Refuses to Think About Her Age
In more than 40 years of running, Rice has suffered exactly one injury — a banged knee from tripping. She doesn’t credit luck or divine intervention.
I don’t think much about my age. It’s just a number.
Her next target is the 80–84 age division, with the Masters World Championships in Korea already circled on her calendar. Of course it is.
Why This Story Is About So Much More Than One Runner
Rice isn’t alone in redefining what aging looks like on a track. Italian sprinter Emma Maria Mazzenga set a W90 world record in the 200 meters at 91 years old and is still chasing faster times.
Together, they represent a growing body of evidence confirming what sports scientists are increasingly vocal about: endurance and speed don’t have to collapse after 60, 70, or even 80.
What typically falls off is consistency. Rice never let hers falter — not for a season, not for a year, not for a single decade across four of them.

She picked up running to shed five vacation pounds. She ended up rewriting what the human body is capable of at 77 — and she’s nowhere near finished.
