100 Mile Races Near Me: Find One in Your State¶
NavRun's race catalog lists hundred-mile courses in 35 states and provinces, with Utah and Virginia holding the most. Each race page shows the time limit, the climbing, and whether crew and pacers are allowed.
Below is how to use it, what the numbers mean, and what the catalog does not know yet.
The catalog is at navrun.app/ultras. It is free and it does not ask for an account.
Are there 100 mile races in my state?¶
Probably. Hundred-mile courses in the catalog sit in 35 states and provinces. Utah and Virginia have six races each, which is the most of any.
If you are in Virginia, that is six hundreds you can drive to. If you are in Utah, the same count. If you are somewhere else, your state is one of the 35 or it is not, and the filter tells you in a second.
Here is how to find out in about a minute:
- Open the catalog.
- Pick your state or province in the State or province filter.
- Pick "100 miles and up" in the Distance filter.
- Open a few of the races it lists and read their pages.
The same two filters work for a runner who wants a hundred in a year and a runner who is only looking. You are allowed to look. A lot of runners read about these races for a year before they sign up for anything, and the page does not ask which one you are.
The catalog also has a Month filter. If you can only travel in September, or you want something cool, set the month and let the list shrink.
One note on the count. The catalog counts courses, and a race with a hundred-mile course sometimes has a shorter one on the same weekend. The 35 states and provinces and the six in Utah and Virginia are hundred-mile courses only. If you want a shorter distance instead, the Distance filter has bands from under 50K up, so the same search works at any length.
What does each race page tell you?¶
Open a race and the facts sit in a table at the top. The ones that matter most when you are choosing between two hundreds:
- Time limit. The overall cutoff for the course. A hundred with a thirty-six hour limit asks something different of you than one with thirty.
- Climbing. Elevation gain in feet. Two courses can both be a hundred miles and ask completely different things of your legs.
- Aid stations. How many, and where, with a cutoff at each one that has a published cutoff.
- Crew access. Which stops your crew can reach.
- Pacers. Whether they are allowed, and from which mile.
- Drop bags. Whether the race offers them.
Facts carry a link to where they came from, so you can check one against the race's own page. Where nobody has checked a fact yet, the page says it has not been checked. It does not guess.
That matters for the pacer and crew numbers below.
Which 100 mile races allow pacers?¶
Most of them. In the catalog, pacers are allowed on 54 of 71 hundred-mile course entries.
The other 17 are not all "no." In the catalog, a blank means nobody has checked, and "no" means someone read the rules and the race refuses pacers. Some of those 17 are the first kind. If a race you like shows an empty pacer field, go to the race's own rules page before you plan around it.
Where pacers are allowed, race pages also show the mile they can join from. That is the number a pacer actually wants. Someone joining at mile 52 needs to know when to be at the aid station, and a runner who is asking a friend to pace needs to know how far into the night the friend will be asked to run.
If you are the pacer, not the runner, the same page works for you. Read the pickup point, then read the cutoff at that station. If you are the one being asked, you will know what you are saying yes to.
Which 100 mile races allow crew?¶
More of them than allow pacers. In the catalog, 60 of the 71 hundred-mile course entries allow crew.
Same rule as above: the other 11 are a mix of "no" and "not checked yet."
The crew rules vary in ways that matter. At some hundreds your crew can reach many aid stations. At others they get a few, and some stops are reachable only by a long walk from parking. The race page marks which stops a crew can reach in the aid station table, and where the race has published directions, it lists them under "Driving your crew."
If you are the one who will be standing at a trailhead at 2am, the useful question is not "are crew allowed." It is "which stops, and how far is the walk." That is on the page where the race published it.
Two other posts go further on the crew side: when your crew should leave for the next aid station, and cutoff times at every aid station.
What 100 mile races are this weekend?¶
The catalog does not have a "this weekend" filter. It has a Month filter, and a status filter that includes registration open, lottery open, waitlist, full, course changed and cancelled.
For a race on a particular weekend, do this:
- Filter by distance and month.
- Open the race and check the edition date.
- Check the status. A race that is full may still have a waitlist.
- Confirm with the race director's own site before you drive anywhere.
That fourth step is the one the catalog asks of you too. Ultras change constantly, sometimes the morning of: a course reroute, a moved date, a closed trail. The catalog reads these off the race's own pages, and a race can change after we last read it.
Looking at next year's hundreds costs nothing, and it is how a start line stops being a someday.
Who this is for¶
The catalog is for the runner who has a hundred on the calendar and the runner who has only typed "100 mile races near me" into a search box and told nobody. It is for the runner on a fifth hundred and the runner who has finished a 50K and is wondering what the next step is. It is for the person who is crewing, the person who is pacing, and the person coming back after a year away who wants to know what is within driving distance.
You do not have to pick one. You do not have to pick a race today.
What the catalog does not know¶
I would rather say this plainly than let you find it.
- It is not every hundred. It is the hundreds NavRun has researched. A race that is missing is missing, not nonexistent.
- Facts go stale. Time limits, crew rules and dates change between years. The catalog shows where each fact came from so you can check it.
- Blank is not "no." A blank pacer or crew field means nobody has checked it yet.
- The numbers here are from one day. The 35 states and provinces, the six in Utah and Virginia, 54 pacer entries and 60 crew entries out of 71 are from a read of the catalog on October 2, 2026. The catalog grows.
If you find a wrong fact, the race page has a form to tell us. A person checks it against the race before anything changes.
