9 October Trail Races Worth Running for the Name Alone
Somewhere out there, a race director sat down with a blank registration form and a serious question: what do we call this thing? And then, bless them, they chose chaos.
October is peak season for it. The heat breaks, the leaves turn, and the trail calendar fills up with events that sound less like athletic competitions and more like dares from a friend who’s had two beers. We went through the whole month and pulled the nine names that made us laugh out loud, then dug into where each one came from. Every race on this list is real, and every one of them is a better story than “Fall Trail Half Marathon.”
A quick note before you scroll: it’s October. Mornings on these courses start in the 30s and 40s, hands go numb by mile two, and you’ll want them back by the time the sun comes up. Plan accordingly. Now, the names.
Javelina Jundred
A 100-mile Halloween party in the Sonoran Desert. Runners lap McDowell Mountain Regional Park through the night while a tent city, a DJ, and roughly a thousand people in costume keep the finish line loud until sunrise. Aravaipa Running calls the whole thing “Jalloween,” and there’s a Best Costume award, which is why you’ll see inflatable dinosaurs and full Elvis at mile 80.
The name: A javelina is the bristly, pig-shaped peccary that wanders the park. Co-founder Geri Kilgariff says a friend nicknamed “Woofie” coined “Javelina Hundred,” and it became “Jundred” purely for the fun of it. Everything since has followed the J rule: Jalloween, Jeadquarters, and the September warm-up race, the Jangover.
Anne’s Get Your Fat Ass Off The Couch Run
Okay, it’s Canada, but this one earns its spot. Club Fat Ass puts on North Shore trail runs under a creed of “No Fee, No Aid, No Course Marking, No Wimps.” You show up at published coordinates, run rainforest singletrack, and look after yourself. The club hands out points for getting lost, spending the longest on course, helping other runners, and picking up trash.
The name: “Fat Ass” is real ultrarunning slang from 1979, when Californian Joe Oakes put on a free, unofficial run for people who’d overdone the holidays. Club founder Ean Jackson brought the format to Vancouver in 1993 as a New Year’s Day hangover cure. Anne’s run is the club’s blunt October reminder to get moving before winter does.
Hairy Gorilla Half Marathon & Squirrelly Six Mile
Twenty-two years running, this Halloween trail race in Thacher State Park starts on gentle grassland, drops into technical singletrack, climbs past an escarpment overlook, and rolls downhill to the finish. Runner’s World named it the “Best Costume Trail Race in America.” Volunteers dress up, the course is decorated, and there’s a graveyard with pre-registered runners’ names on the headstones.
The name: Pure Halloween silliness from organizer ARE Event Productions. The course promo promises “gorillas that have gone bananas” and “nutty squirrels” along the route; the Squirrelly Six is the shorter, twistier option.
Lastest Not Fastest
A last-person-standing race in the Columbia River Gorge. Everyone starts a flat 4.13-mile loop on the hour, every hour. Finish inside 60 minutes and you line up again; miss it and you’re done. Fast runners get more rest, slow runners get less, and it rolls through sunset and sunrise over the river until exactly one person remains.
The name: The format flips everything you know about racing, and Go Beyond Racing says it best: “You don’t have to be FAST, you just have to be LAST.”
Will Run for Coffee/Beer 5K
A riverside trail 5K along the Shiawassee that finishes at a gym with a mobile coffee bar and a beer tent waiting. Dogs, strollers, and kids are welcome. At registration you declare your allegiance, and your finisher shirt, your mug or pint glass, and your post-race pour all match it.
The name: A joint production of a gym, a coffee roaster (Foster Coffee Co.), and a bar (The Sideline). The slash is the whole joke. You’re running for one or the other, and the race would like to know which.
No Name Trail Races
Runnable climbs, winding singletrack, steep fire-road ascents, and long smooth descents through Cheeseboro Canyon in the Santa Monica Mountains. The 50K packs in 4,416 feet of gain; the 10K gets you 871. It’s a low-key, locals-first event with multiple aid stations and none of the big-race production.
The name: Billed as “The Outlaw Race with No Name,” a wink at Clint Eastwood’s Man With No Name and at the race’s no-sponsor, no-pressure ethos. Not naming it became the name.
Cactus Rose
A 25-mile loop through Hill Country State Natural Area with roughly 2,500 feet of climbing per lap and almost nothing flat. The organizers describe the footing as “rocks…lots and lots of rocks.” Aid stations hand out water and ice, and that’s it; everything else you stage yourself in drop bags. It’s self-supported suffering in the most Texan way possible.
The name: The trails are lined with sotol, a spiky desert plant that slices shins, and the “rose” is the sarcastic part. The race promises something beautiful and delivers something that draws blood. Tejas Trails says it plainly: “This race was designed to test runners over rugged technical terrain.”
Hoofin’ It for Hunger
A rural Montana run put on by county Farm Bureaus, with every dollar of proceeds going to local food pantries. Past courses have wound through corn fields, under cottonwood canopy along the Yellowstone River, and across open pasture. The organizers’ own pitch: “We are rural and we love it that way!” Check the course map before you commit; some years lean more dirt road than trail.
The name: “Hoofin’ it” is old ranch slang for going on foot, and the pun lands twice. It’s a farm-country run, and the money feeds people. Easily the friendliest name on this list.
Red Dirt Rambler
A 9-mile loop through the pine woods at 1North Adventure Trails, repeated as many times as your distance demands. Texas Outlaw Running Company runs it, and the format means a whole crew can race different lengths on the same day and meet back at the same finish.
The name: The soil in this corner of Louisiana is famously rust-red and stains everything it touches. “Rambler” sells the vibe: a long amble through the woods rather than a race against the clock. By the finish your shoes will match the trail.
Dates above are confirmed for 2026 except where noted. Always double-check the race site before registering, because race directors who name things like this are also the kind who move dates on a whim.
