Arizona ultramarathon calendar
Compare a selective calendar of Arizona multiday and long-ultramarathon races—from short supported loops and invitation-only track racing to high-country trails, self-supported stages, and desert-to-mountain crossings. Use the table to shortlist race systems, then verify the current rules with each organizer.
Start with the operating model, terrain, cutoff, and edition status. Then open a race record for aid, crew, elevation, weather, logistics, caveats, and organizer sources.

A supported short loop can simplify navigation, resupply, and crew access. A point-to-point crossing adds transport and withdrawal logistics, while a self-supported stage race shifts much of the problem toward pack weight, recovery, and mandatory equipment.
Desert Solstice is different again: it is a small, qualification-based track event. Compare entry rules and support systems before comparing headline distance alone.
The listed venues span metropolitan desert loops, the Mogollon Rim and Flagstaff high country, remote plateau terrain, and routes that climb from Sonoran desert toward mountain towns.
Those settings can create very different altitude, exposure, footing, and overnight-layering problems. Treat the event notes as planning context, then use the current route guide and local forecast for final decisions.
The current listed editions cluster from September through May rather than peak summer. That reduces neither heat nor weather risk: daytime exposure, cold desert nights, high-country storms, and wind can still affect the same race weekend.

No. The listed events include desert and mixed-surface loops, mountain and high-country trails, a track race, self-supported stages, and long point-to-point crossings.
The current registry includes fixed-time, 100-mile, 200-plus-mile, stage-race, and fixed-distance options. Some festivals offer several formats under one event record.
Each event record shows the organizer sources used for its review, while the directory scope note displays the review-date range. Dates, permits, routes, registration, and rules can still change, so confirm them with the organizer before making plans.
