NIWOT'S CHALLENGE
13th Annual
Saturday, May 2, 2026
Runner Capacity: 40
Start/Finish: Along the South Platte River || Sedalia, CO
Niwot’s Challenge is not a race. It’s a reckoning.
Somewhere in Colorado’s Front Range, where trail maps grow fuzzy and reason begins to rot, lies a sacred gauntlet cloaked in secrecy and mischief. Inspired by the Barkley Marathons and the infamous More and More Difficult 50K, Niwot’s is a grassroots trial of human potential, birthed from the wild heart of the ultrarunning underground.
Details? There are few. What you learn, you earn. The course remains unpublished. The Sacred Waypoints are not digital. And the only map you’ll ever fully trust is the one sketched into your soul “out there.”
Access is by invitation and acceptance only. You won’t find your way by scrolling. You’ll have to ask the right questions… or better yet, show up ready to become one.
⚠️ Warning to the Curious
Niwot’s is not for beginners, Strava chasers, or those who need aid every few miles or melt in the face of chaos. This is for edge-walkers, seekers, and nitwits willing to suffer on purpose.
Expect:
- Significant off-trail navigation
- Minimal aid and maximum autonomy
- Heavy reliance on a map, a compass, intuition, or a wiser fool ahead of you
- Shared irreverence, off-color humor, and a strong community of dirtbag philosophers
If you’re looking for comfort, keep scrolling. If you’re seeking transformation, welcome to the threshold. You have been warned.
ABOUT THE ADVENTURE
The Course
The Niwot’s course is a riddle written in rock, bushwhack, and bruises. You won’t find mileage stats or GPX files here. What you will find is an unforgiving journey that stitches together long stretches of off-trail navigation, the occasional scrap of dirt road, and a few humble trails that barely remember they exist. This is not a loop you run. It is a path you earn.
To complete the course, nitwits must travel the route exactly as designed and retrieve their unique code from each of the Sacred Waypoints. Miss one, and the spirits will know. Your Becoming will remain incomplete.
But this is no scavenger hunt. It’s a soul thesis.
A Graduate-Level Sufferfest
This is a doctoral dissertation in adversity.
You don’t just “run” Niwot’s. You endure it. You negotiate with it. You bleed into it. Participants are expected to have significant experience in ultrarunning, orienteering, adventure racing, or prolonged psychological unraveling in the wilderness. You will not “run” this. You will suffer it slowly.
There are no podiums here, only the slow erosion of identity until you either:
- Stagger into camp as a newly minted Chief,
- Attempt a Deity Finish and disappear into legend,
- Or stumble back with a crooked grin, proud to be a happy quitter.

The Entry Process
Entry Fee: FREE*
(*A donation is encouraged, monetary or otherwise. Surprise us.)
🛑 Let’s be clear: this is not a race.
It’s a sacred sufferfest. A navigational hallucination. An unsanctioned ceremony for the slightly unhinged. There are no t-shirts. There are no awards. There is only what you find “out there.”

Selection Ritual
Here’s how we draw the Circle of 40:
The First Five Chiefs who apply are accepted immediately.
- Up to 15 Returning Nitwits (those with past attempts but no finish)
- Up to 15 Virgins (first-time Niwot’s applicants)
- Five Wild Cards, hand-picked by The Lorax himself
- What If the Numbers Don’t Add Up?
If fewer than 40 apply:
- We follow the order above until those groups are full
- Then we accept all remaining Chiefs
- Then we alternate: one Returning Nitwit, one Virgin, until full
- After that, it’s first come, first served
If more than 40 apply:
- We fill the field per the order above
- Then initiate a waitlist, in order of received applications
⚠️ Warnings for the Unready
We reserve the right to refuse entry to any applicant without explanation.
This is a graduate-level event. You are expected to:
- Have legitimate experience in ultrarunning, orienteering, long-distance trekking, or adventure racing
- Know how to read a paper map and use a compass
- Or be actively learning those skills before race day
This is not a place for ego.
This is not a place to prove yourself to others.
This is a place to meet yourself, with scrub oak in your loins and no one coming to save you.
ADDITIONAL INFORMATION
Niwot’s Challenge is not led; it is guarded.
At its heart stands the Tribal Council: a circle of seasoned nitwits who’ve earned their scars “out there.” These elders oversee the spirit of the event, offering guidance on applicant selection, shaping the evolving lore, facilitating Vision Quests (solo missions or small-group trainings on parts of the course), and, when necessary, serving as the event’s disciplinary tribunal.
The Order of Becoming
Every participant enters Niwot’s known only by their Spirit Animal, a totem of the self they think they are.
Finish a full loop within 30 hours, and you’ll earn your Chief Name, a sacred rite of passage that marks your transformation.
Complete a full loop in each direction within 60 hours, a feat so daunting that only two have attempted, and you’ll step into the mythic unknown: the realm of the Deity. (None have returned… yet.)
Before You Arrive
In the weeks before the event, each accepted nitwit will receive digital dispatches containing:
- The official course map
- Crew and aid details
- Additional rules and rituals
- The sacred start time
These messages are not just logistics; they are invitations to prepare your body, your mind, and your spirit for what lies ahead. You will have time to study the terrain, gather your tools, and come to terms with the truth: you chose this.
