There’s A Half Marathon On The Western States Trail Where You Stop To Iron Your Shirt

Somewhere in the hills above Auburn, California, on part of the most hallowed trail in American ultrarunning, a group of runners recently completed a half marathon while carrying full-size ironing boards on their backs. This is Iron X, and no, it is not a joke. Well, it is, but it’s a real one.

The premise: run a half marathon along a stretch of the Western States 100 course, stopping at eight iconic locations to remove a button-up shirt, iron it, and put it back on. Miss a location or fail to document it, and you take a 10-minute penalty. The winning time in 2026 was Sean Thon’s 3:54:25, which tells you everything about how much the ironing slows you down.

Yes, Extreme Ironing Is A Real Sport

For the uninitiated: extreme ironing has existed since the late 1990s, generally credited to Englishman Phil Shaw, who reportedly coined the term after choosing to iron his laundry outdoors rather than face the chore inside. It grew into an actual pursuit with a 2002 world championship in Germany, a 2003 Channel 4 documentary, and a genuine record book. People have ironed at Everest Base Camp, 138 feet underwater, and while parachuting. Iron X simply welds this beautiful nonsense to a trail race.

The Eight Irons

The locations are half the fun, and pure Auburn-area trail folklore. Ironists must press their shirt at, among others, the old foundation at Robie Point, knee-deep in the river just south of No Hands Bridge, atop the remains of a dead car, and beside the historic courthouse. The most committed stop is arguably the river iron, because nothing says “well-pressed” like standing in cold water with a battery-powered iron.

The Rules Are Gloriously Specific

This is where Iron X reveals itself as the work of people who take their joke very seriously. The regulations, paraphrased only slightly:

• Your ironing board must be at least 3’3″ long and 11″ wide, with full-length legs. No tabletop boards, you cheat.
• Battery-powered irons only (for reasons that should be obvious on a trail), with an ironing face of at least 4.5″ by 9″. Plastic irons are permitted.
• You carry your own board, iron, fuel, and water the entire way. No muling.
• Every iron must be photographed or filmed, geo-tagged, with the location, ironist, iron, and board all clearly visible.

The organizers even offer earnest advice on how to carry an ironing board for 13.1 miles, suggesting snowboard-mountaineering packs or rigging shoulder straps directly to the board. This is, in the truest sense, a “fatass” as organizers described: no course markings, no medals, no aid to speak of, just a group of people who decided a half marathon wasn’t quite absurd enough on its own.

Why This Is The Most Running Thing Ever

It would be easy to file Iron X under “internet weird” and move on. But it’s actually a perfect distillation of trail running’s soul. This is a sport that already sends people over 100 miles through canyons in the July heat for a belt buckle, that invented the fatass so friends could suffer together for free, and that has always prized creativity and self-reliance over medals. Strapping an ironing board to your back and pressing a shirt in a river is just that spirit turned up to eleven.

Iron X 2027 is already on the calendar for July 10 in Auburn. And somewhere out there, someone is training with an ironing board on their back, wondering if they can shave a few minutes off the river iron. Run happy, ironists. Run wrinkle-free.
