The trail-running world is mourning the loss of one of its brightest stars.
Megan Kimmel, the American ultrarunner who dominated skyrunning circuits across the globe and shattered records on some of the most punishing mountain terrain on earth, has died at the age of 46.
The Skyrunning Federation broke the news on Instagram, sending shockwaves through a tight-knit community that had come to regard the Silverton, Colorado native as far more than just an elite competitor.
No cause of death has been reported — but what is already clear is that the void she leaves behind is immeasurable.

From Trail Runner to World Champion
Kimmel first laced up for trail running back in 2003, but it was a decade later that her career truly ignited.
When she stepped into the skyrunning scene in 2014, she didn’t ease her way in — she arrived with force.
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
In her very first season on the circuit, Kimmel claimed a silver medal at the 2014 Skyrunning World Championships in Chamonix, France — a staggering debut that signaled to the world exactly who they were dealing with.
Then came 2015, and a performance that still hasn’t been topped.
Kimmel set the Dolomites SkyRace course record at 2:57:57 — a mark that remains unbroken to this day, a testament to just how far ahead of the field she was running.
By 2016, she had claimed the ultimate prize: the Skyrunner World Series Championship, cementing her place among the sport’s all-time greats.
An extraordinary athlete and true skyrunner whose legacy will live on.
The Record That Took 39 Years to Fall
For anyone who thought Kimmel’s best days were behind her after 2016, she had a very clear answer waiting at the top of a Colorado mountain.
At the 2018 Pikes Peak Marathon in Manitou Springs, Colorado, Kimmel didn’t just cross the finish line first — she obliterated a record that had stood for 39 years, clocking an astonishing 4:15:04.

Nearly four decades of history, rewritten in a single race.
Her momentum carried into the following year, where she claimed victory at the 2019 Broken Arrow 52K in Squaw Valley, California, finishing in 5:30:43 and adding yet another iconic win to an already remarkable résumé.
More Than a Champion — A Community Builder
Records and titles only tell part of Kimmel’s story.
Those who ran alongside her — or looked up to her from the sidelines — describe a woman who gave as much to the people around her as she did to the sport itself.
Known for mentoring younger athletes and fostering genuine connection within the ultrarunning world, Kimmel’s influence extended well beyond race day. Even after she retired during the COVID-19 pandemic, she remained a beloved and active presence in the community.
The tributes pouring in across social media paint the picture of someone who made everyone around her feel like they belonged.

There aren’t words yet to describe the enormous void she leaves behind in Colorado’s San Juan Mountains and the mountains beyond. We’re really not sure what the world is going to do without you, Megan. You will continue to be so loved.
Those words, shared on Instagram by ultrarunner and journalist Meghan Hicks, captured what so many in the community are feeling but struggling to express.
Fellow elite ultrarunner Ragna Debats offered her own deeply personal farewell, recalling what made Kimmel so singular — not just as a competitor, but as a human being.
Very sad to hear. Megan was the person who made me feel competing was a game rather than a fight. I have so many good memories of sharing a room, running and chatting with her. She’ll always live on in my heart.
A Legacy Written in the Mountains
Megan Kimmel spent her career racing across some of the world’s most unforgiving terrain — the Dolomites, the Rockies, the Sierra Nevada — and she made it all look like something close to poetry.
She was 46 years old. A world champion. A record-breaker. A mentor, a friend, and by every account, the kind of person who made the mountains feel a little more welcoming for everyone who followed in her footsteps.
The trail-running community’s loss is immeasurable — but so, too, is the legacy she leaves behind.
