Registration will be posted at 12:00p (noon) MST on September 19th. GPX downloads are temporarily disabled as the route is being finalized. Couple of major changes on Mt. Lemmon: The AZT has officially been moved off upper Oracle Ridge over the the adjacent Red Ridge using Catalina Camp as a connector back to Oracle Ridge at Dan Saddle. Mining operations in the area necessitated the need for a permanent change. 800 riders will now use the Lemmon Pusch route while ascending Mt. Lemmon. 300 riders will continue to use the paved Catalina Hwy.

GPX files have been published for the October Grand Depart. The 300 file, v4, should be the final version. For the 800, v6 can be used for planning, but it is NOT the final version as construction continues on the Highline trail re-routes. That is anticipated to be completed during the summer months.
In the meantime, there are 7 other updates to the route since last October, 5 along the 300 and 2 farther north for the 800, not including the upcoming Highline changes. Below are maps showing the changed areas. The pink line is the new route for 2023, blue was the published route for 2022. I’ve also included the route mile marker, MM, at which each new section begins.

GPX files have been updated and posted for any spring ITTs. So far, only minor changes. One short re-route near Cott Tank in the Canelo Hills for both the 300 & 800. A 3 mile re-route just north of Sunflower on the 800. If the Temporal Gulch re-route project wraps up during the spring ITT window, look for another update. No ETA on that currently.
September 24, 2022
GPX update to the 800 files. No change to the 300 files. The Coconino Nat’l Forest updated the Pipeline Fire Closure and the AZT is now open on the north side of Mt. Elden, no reroute required for this area. Also, a small reroute near Sunflower on the north side of AZ87 has been added.

REGISTRATION CHANGE!! For anyone who plans to sign up for the Grand Depart on October 20, I had to move the registration back 4 hours on September 20. Sign-up will go live at 11am AZ time (Mountain Standard/Pacific Daylight Savings). I had a conflict with my new work schedule and can’t guarantee I’d be available to post the link at the previous time. I’ll post this elsewhere, but please help spread the word. This does not affect the start of the ride, only the registration for the Grand Depart.
For anyone planning to ITT the route, please reach out to me directly for a separate registration link. Thanks.

The AZTR Rules have been updated. Please review if you plan to take on the AZTR Challenge. It is the rider’s responsibility to know the rules and inform family & friends of what is expected.
Registration will be posted on September 20, 2022 at 11am AZ time (MST) on this website, the Facebook AZTR page (Arizona Trail Race (mtb)), the Instagram account (@azt300_800) and the Ultra Racing Forum page on Bikepacking.net. Remember, there is a 60 rider limit combined for both the 300 & 800.
For those wanting more of a challenge, the southbound versions of both the 300 & 800 have been altered for additional difficulty. Tracks have not yet been finalized and are only available as ITT attempts. These additions only make routing sense in the southbound direction.
Questions? A great place to start is the FAQ page: https://azt300-800.com/faq/
