No Crew, No Quit: Katie Gunvalson Sets Ouachita Trail FKT

Katie Gunvalson didn't grow up outdoors. Now she's rewriting the record books  and redefining what's possible for women in the FKT world.

Katie Gunvalson had never heard of a marathon until a friend dared her to run one after college. She wasn't an athlete. She didn't camp, didn't hike, didn't own trail shoes. Her family vacations were beach chairs and paperback novels, not summits and ridgelines.

Over a  decade later, in November 2025, she stood at the western terminus of the Ouachita Trail in Oklahoma; alone, self-supported, carrying everything she'd need to cover 223 miles and 35,000 feet of elevation gain across some of the most technical terrain in the country. Three days, twenty hours, and forty-two minutes later, she finished with the overall women's record. A record that was faster than the previous supported time set by an athlete backed by a large crew.

She did it alone.

From Road Runner to Record Setter

Gunvalson's path to the Ouachita didn't follow a straight line. After years of competitive road marathoning, the pandemic erased her racing goals overnight. She pivoted to the trails behind her Portland home and quickly became consumed by the world of Fastest Known Times.

What followed was a string of ambitious attempts and painful failures. Multiple Washington section bids fell short. A wildfire shut down her years-in-the-making PCT attempt on day one. An Arizona Trail effort ended with injury at mile 200. She won "Most Tragic FKT" at the 2024 Jeffrey Awards, and she'll tell you she earned it.

"I felt like I had no business being out there," Gunvalson says. "I had no idea what I was doing, especially when I wasn't successful."

But quitting wasn't in the playbook. After crewing for fellow FKTer Nick Fowler on his PCT attempt in summer 2025, she emerged trail-hardened and dialed. She set the Oregon Coast Trail women's overall record in July, running 50+ more miles than the previous self-supported record holder and averaging 54 miles per day. The Ouachita was next.

The Ouachita: A Different Kind of Hard

The Ouachita Trail doesn't get the name recognition of the PCT or Appalachian Trail, but it punishes with a relentlessness all its own. Rocky, technical terrain hides under blankets of freshly fallen leaves. Water sources run dry. Elevation is non-stop up and down.

Gunvalson spent half of every day navigating in darkness with only eleven hours of daylight and twenty-hour pushing days. Her legs were shredded by brambles. Her watch died with seventeen miles to go. She ran out of both food and water in the final push.

"It was totally different from the West Coast," she says. "The PCT is a highway compared to this."

The Fueling Problem No One Talks About Enough

For Gunvalson, the biggest threat wasn't the terrain but eating. Multi-day FKT efforts demand 200 to 300 calories per hour, but extreme exertion suppresses appetite and wrecks digestion. It's the paradox every endurance athlete knows: your body screams for fuel while refusing to accept it.

"I'm notoriously a bad eater on these things," Gunvalson admits. "I went through all of my liquid and gel calories and then had a whole bag of food I couldn't eat."

On the Ouachita, she relied on RecPak to bridge the gap between what her body needed and what her stomach would tolerate. She'd mix a pack in the evening, drink half before her three-hour sleep window, then finish the rest at first light, thus turning one pouch into both a recovery shake and breakfast.

"Whatever the nutritional makeup is, it's really satisfying," she says. "I actually feel full after I have it. I don't feel like I just had a sugary drink. It feels more sustaining and just more quality nutrition."

Each RecPak delivers 700 calories and 43 grams of protein in a no-cook, just-add-water format- exactly the kind of caloric density that keeps athletes moving when solid food fails.

What Comes Next

Gunvalson isn't slowing down. The Oregon Coast Trail and Ouachita records were breakthroughs, but she sees them as proof of what's still possible, not a finish line. She has big plans on the horizon, and if her track record is any indication, the failures that shaped her are about to pay serious dividends.

Her advice for anyone standing at the edge of something that feels too big: "Give yourself a chance. You don't know what you don't know. Just because you don't know something now doesn't mean it's not for you."
