The Margonaut 2026

The Margonaut is a trail marathon held in the Granite Dells area of Prescott, Arizona, taking place in November. It is part of a series of Prescott trail events organized by the same local group, which also includes Sierra Prieta, a 50K, and Saddles, a 50- or 100-mile trail walk. The defining characteristic is the location: Granite Dells signifies a desert-rock trail marathon, distinct from a road race through the city. While specific race details are limited, they indicate a Prescott trail running schedule that spans from a summer 50K to a fall ultra-distance walk, culminating in this marathon-distance event.
