The Granite Mountain Grind Ultra 50K Trail Race returns to Prescott, Arizona on September 26th, offering a challenging experience for seasoned runners seeking adventure in rugged terrain.
Located at the heart of Prescott’s granite landscape, the race starts from the Almosta Ranch Road area and winds through the scenic trails surrounding Granite Mountain. Runners will encounter rocky climbs and fast descents over pristine singletrack paths surrounded by towering boulders and juniper-studded landscapes. The setting is raw and technical, providing a stark contrast to more manicured running environments.
Established in 2026 as an inaugural event limited to just 100 participants, the Granite Mountain Grind aims to provide a high-quality trail-running experience that respects both nature and competitors' hard work. Each year’s race supports local causes through entry fees and participant engagement, fostering community involvement and appreciation for Arizona's unique outdoor spaces.
The course covers rugged terrain with rocky climbs, fast descents on singletrack paths, and stretches of dry trails under juniper trees in the Prescott area. The route is well-marked with aid stations strategically placed along the way to ensure runners remain hydrated and fueled throughout their journey. With three fully stocked aid stations and two additional water stops interspersed across the course, participants are assured support as they navigate this challenging landscape.
Weather conditions on race day typically see an average temperature of 21.5°C with a range from 15.8°C to 27.2°C, making for comfortable running despite occasional wind speeds averaging at around 9.7 km/h and minimal rainfall risk. The course is expected to be dry and hard underfoot, enhancing the technical challenge but providing clear visibility of trail markers.
