Runners set out from Ruby Rider Ranch onto dirt roads toward Wire Mesa, passing the edge of the Smithsonian Butte Wilderness before transitioning onto singletrack. They complete a loop around Wire Mesa, then return via dirt roads to finish back at Ruby Rider Ranch.
Dirt road out to a loop of the flowing singletrack around Wire Mesa, and dirt road back.
The Zion Ultras run across high-desert mesas outside Zion National Park, linking long stretches of singletrack, slickrock and exposed desert trail. The courses are demanding and the terrain ever-changing: long sustained climbs, narrow rim sections, and stretches with technical footing. Everything starts and finishes from basecamp at Smithsonian Butte, at Ruby Rider Ranch in Apple Valley, Utah, with five distances sharing the same start line: 100 Mile, 100K, 60K, 30K and a trail half marathon. The 100 Mile is the race most runners know as the Zion 100.
Matt Gunn founded Ultra Adventures in 2012 with the Zion 100, and spent years building a series of races that opened up the Grand Circle to runners from around the world. Ultra Adventures is now run by Aravaipa Running, which directs the Zion Ultras alongside the Bryce Canyon Ultras, the Antelope Canyon ultras and the Tushars.

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.
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.
