Point-to-point 50K on the Black Canyon National Recreation Trail from Mayer High School (Spring Valley, AZ) to Deep Canyon Ranch (Black Canyon City, AZ), run the day after the 100K on the same opening ~19.4 miles of trail. Not a Western States qualifier and carries no pacers.
Same opening trail as the 100K. The first ~20 miles are fast and downhill; the race advises saving energy for the final stretch after Bumble Bee Ranch aid station.
Point-to-point 100K and 50K ultramarathons on the Black Canyon National Recreation Trail through Arizona's Sonoran Desert, both starting at Mayer High School in Spring Valley, AZ. The 100K (Saturday) finishes at the Emery Henderson Trailhead near New River; the 50K (Sunday) finishes at Deep Canyon Ranch near Black Canyon City. Race directed by Aravaipa Running, presented by HOKA, and a Western States 100 Golden Ticket race.
First run in 2014. Originally paired the 100K with a 60K second distance; the second distance was later changed to a 50K (the site's own Course Records section separately lists a retired '60K (Old Course)' record, last set 2024). A 'High Water Reroute Course' record also exists from 2019, indicating the course has been altered at least once for high water on the Agua Fria/Black Canyon crossings. Became a Western States 100 Golden Ticket race and, per the race page and UltraSignup listing, joined the World Trail Majors collection.

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.
