Arizona's 100-mile options are deliberately spread across different settings and times of year. Low-desert exposure, cool nights, higher-elevation terrain, wind, and storms can produce very different race plans even within one state.
Treat the event record as comparison context rather than a forecast. Use the organizer's latest runner guide and a current local forecast for final clothing, water, cooling, and travel decisions.
A looped race may simplify access to food, shoes, and crew, while a remote trail course can make aid gaps, vehicle access, pacers, drop bags, and withdrawal transport more important.

The count shown at the top is generated from the source-checked event registry. It can change as editions are verified, archived, added, or removed.
No. The listed races include short desert loops, point-to-point mountain crossings, and forest or high-country trails. Compare terrain, elevation, season, aid access, and course model on the individual event pages.
The directory does not rank races as easiest. A flatter loop may simplify navigation and supplies, but heat, repetitive loading, cutoffs, entry standards, and personal experience can still make it unsuitable for a particular runner.
