Who's going to Hell Creek 100?
Free. You can start with nothing.
Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this.
Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.
Distance
Our math
20 miles
The race says “The races consist of 20(ish) mile loops with no repetition. One loop for 20 milers, three loops for 100k runners, five…”. We worked the total out from that.

The course

One loop of the Switchgrass Mountain Bike Trail at Wilson State Park, the same loop the longer races repeat. Finishers get a medal, a shirt and a beer. Crew can meet 20 milers at the start/finish only.
The race
What this one is
A weekend of races on the Switchgrass Mountain Bike Trail at Wilson State Park, near Sylvan Grove, Kansas. Every distance runs on loops of rugged, exposed singletrack beside Wilson Lake: a 10K, a 20 miler, a 100K, a 100 miler, a five-person 100-mile relay, and the Pure Hell 140, which needs a previous 100-mile finish to enter. The 2026 edition is on Halloween weekend, with a costume contest.

every one of these is read by a person before it changes anything
Ran this race? Tell the next runner what you know.
Nobody sees it until we have read it. No account, no sign-in.
See something wrong or out of date? Suggest an edit.
This changes nothing on the page on its own. Somebody checks it against the race first.
Were you out there? Say which stops a text got out from.
Nobody sees it until we have read it. No account, no sign-in.
Seen a course preview or a film of this one? Send it over.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
Have the GPX? Send us the link.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
Are you the race director? Get in touch and we'll make it right.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
Where this came from.
Every fact on this page records its source and when we last checked it: 69 sources for this race. Hover a source link to read the sentence it came from.
31% of what we track for a course is filled in. The rest says "not checked yet" rather than guessing.
Ultras change. We will tell you when this one does.
Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.
No account, and nothing to cancel.
What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.
I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
