Antelope Canyon Ultras runs out of the Page Sports Complex in Page, Arizona, on a course of deep sand, open slickrock and slot canyons above the Colorado River. Four distances share the one start line: 50 Mile, 55K, 30K and a trail half marathon. The two long courses drop into narrow canyons on fixed ladders and cable-assisted sections, cross open desert near Horseshoe Bend, Marble Canyon and Lake Powell, and finish on the Page Rim Trail. It is run in early March, and the race says the terrain shows no mercy: deep sand, rising slickrock, and more sand waiting on the other side.
The first Antelope Canyon 50 Mile was run on 1 February 2014, with Matt Gunn as race director. Gunn had founded the Ultra Adventures series two years earlier with the Zion 100. The race sat in February through 2018 and has been held in March since 2019. The 2026 edition was put on by Vacation Races, and from 2027 the race is run by Aravaipa Running, which now directs Ultra Adventures.

These are other people's work and we link straight to them. Watching costs nothing and needs no account. More of them: every race we hold, on film.
Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
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.
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.
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.
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.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
