Who's going to Norris Ultra Dam Hard Trail Race?
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.

The course
Where it goes
loop · 5 aid stations
One lap of the same loop the 50k runs twice, out and back from the pavilion near the Tea Room, on single track trails and jeep roads through Norris Dam State Park and the Norris Municipal Watershed.
Single track trails and jeep roads across both Norris Dam State Park and the Norris Municipal Watershed. Runners know one climb by name: Butt Slide, which is also where one of the two aid stations sits.
The race
What this one is
A 50k and a 25k on single track trails and jeep roads through Norris Dam State Park and the Norris Municipal Watershed in East Tennessee. Both races leave from the pavilion near the Tea Room and run the same loop, one lap for the 25k and two for the 50k. The Knoxville Track Club has been putting it on as part of its Treadin' Trodden Trails season for well over a decade, and the aid stations sit on roads, so the people who came to support a runner can reach them.

- Cutoff philosophy
-
Four hours and forty minutes. A sweeper travels with the back of the field, and the race asks everyone to keep moving quicker than 18 minutes a mile, so that its volunteers are not out in the woods far longer than they should have to be.

What you know
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See something wrong or out of date?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.
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: 71 sources for this race. Hover a source link to read the sentence it came from.
29% 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.
