A record that had stood for nine years just got shattered — and it took one ultrarunner three attempts to finally do it.
Joe “Stringbean” McConaughy has officially rewritten history on the John Muir Trail, claiming the men’s supported fastest known time in a jaw-dropping 2 days and 16 hours flat.
The feat is the culmination of years of failed attempts, relentless preparation, and an almost obsessive familiarity with one of America’s most demanding trails.
Here’s how he did it — and why the endurance world is talking about little else right now.

Nine Years, One Record, Zero Challengers — Until Now
French ultrarunning legend François D’Haene set the previous men’s supported record back in 2017, clocking in at 2 days, 19 hours, and 26 minutes across the trail’s grueling 223-mile stretch through California’s Sierra Nevada.
For nearly a decade, that number stood untouched.
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
Plenty tried to crack it — especially during the FKT boom that exploded in popularity throughout the COVID-19 pandemic — but D’Haene’s mark proved bulletproof. Until September 2026.
McConaughy didn’t just edge past the record. He beat it by 3 hours and 26 minutes, finishing at the trail’s northern terminus at Happy Isles in Yosemite National Park early Wednesday morning, well before 6 a.m. local time.
Who Is “Stringbean” — And Why Is Everyone Talking About Him?
If you’re not already familiar with McConaughy, buckle up — his résumé is staggering.
The nickname “Stringbean” originated during his thru-hiking years, earned for his tall, lean frame, and it followed him seamlessly into elite trail running. He holds fastest known times on the Appalachian Trail, Pacific Crest Trail, Long Trail, and Arizona Trail, among several others.
On the racing circuit, he’s equally formidable. His credits include a win at the 2022 Cocodona 250 Mile, a third-place finish at the 2025 Black Canyon 100k, and a 14th-place showing at the notoriously brutal 2025 Western States 100.
This is someone who doesn’t just run long distances — he redefines what’s possible on them.

Two Failures Before the Breakthrough
McConaughy’s relationship with the John Muir Trail runs deep, and not always smoothly.
He made his first supported record attempt in 2022 — falling short. A second try in 2024 ended the same way. What he did walk away with from that 2022 run, however, was the men’s unsupported north-to-south record, a title he still holds today.
Beyond the record bids, McConaughy has spent significant time hiking and guiding on the trail itself. By the time he set off northbound from Whitney Portal on Sunday, September 20, 2026, at 1:47 p.m. Pacific Daylight Time, the route wasn’t just familiar — it was practically home.
Mile by Mile: How the Record Unfolded
The opening 100 miles told a fascinating story of two athletes separated by nine years, running almost identically.
Through Sunday afternoon and into Tuesday morning, McConaughy’s pace tracked almost perfectly alongside D’Haene’s historic run. That stretch included summiting Mount Whitney — the highest point in the contiguous United States at 14,505 feet — along with six additional mountain passes.
Then, around the 135-mile mark on Tuesday morning, something shifted.

McConaughy began pulling ahead — slowly at first, then unmistakably. At that point, he held roughly a two-mile lead over D’Haene’s historical pace. By Tuesday night, after covering an extraordinary 185 miles total, that gap had ballooned to over nine miles ahead of record pace.
Fewer than 40 miles remained. The record was within reach.
A Final Night Push Through the Sierra
That last stretch through the darkness went, as McConaughy’s tracker confirmed, smoothly.
There were fluctuations — at one stage, the gap over record pace narrowed to around four miles, likely reflecting differences in where each athlete chose to rest and resupply. But those are the variables of a supported effort spanning nearly three days across some of the most dramatic terrain on the continent.
When McConaughy crossed the finish line at Happy Isles, his tracker showed him 13 miles ahead of D’Haene’s pace. The clock read 2 days, 16 hours, 0 minutes.
The Numbers Behind the Feat
To appreciate just how remarkable this performance is, consider the scale of what the John Muir Trail demands from anyone who dares to run it.
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
- 223 miles of total trail distance through the Sierra Nevada
- Approximately 47,000 feet of total climbing
- High-altitude passes, granite domes, remote valleys, and unpredictable wildlife
- Mount Whitney summit at 14,505 feet — the lower 48’s highest peak
McConaughy averaged a pace of roughly 3.5 miles per hour across the entire effort — and that figure accounts for every logistical stop, nap, and crew resupply break along the way.
That’s not running. That’s a different category of human performance entirely.
What This Moment Means for FKT History
Fastest known times have exploded in cultural visibility over the last several years, drawing mainstream attention to athletes who operate at the furthest edges of endurance sport.
D’Haene is no ordinary record holder — he’s a globally competitive force in trail running who set his John Muir Trail benchmark at the height of his powers. The fact that his mark survived for nine years, through an era of surging interest and increasingly serious competition, says everything about its quality.
McConaughy didn’t just outlast the record. He hunted it across three separate years.
For anyone who has followed his journey — from the Appalachian Trail to the Pacific Crest, from failed JMT attempts to this triumphant Wednesday morning finish — the third attempt carries the weight of everything that came before it.

Stringbean finally got his record. And the Sierra Nevada will never quite look the same again.
