The courses travel through high country and backcountry terrain, including sections on the Continental Divide Trail and climbs that reach toward 9,000 feet. Runners move from high desert hills into ponderosa pine forest, providing a mix of desert and forest landscapes and extended scenic stretches. Terrain is described as rugged but runnable, and some sections are remote with true backcountry character.
Support on course includes well-stocked aid stations offering hydration, nutrition, and additional food at key locations. Conditions can include large temperature swings between warm daytime conditions and cooler nights. The start area is a few miles east of Silver City near historic Fort Bayard before entering the Gila backcountry. Registration for the event closes on October 15 at 11:59 PM Mountain Time.
