Black Canyon Ultras : February 14–15, 2026
Black Canyon Ultras is a two‑day trail event featuring point to point 100K and 50K races on the Black Canyon National Recreation Trail in Arizona. The courses begin at Mayer High School in Spring Valley and finish at Emery Henderson Trailhead (100K) and Deep Canyon Ranch (50K). The route follows a mixture of single track, jeep roads, and sections of an old stagecoach road through the Sonoran Desert, with multiple creek crossings and several gates where runners must close them behind them.
- 100K : 62.2 miles
- 50K : 32.2 miles
Key course facts: the 100K has an estimated +5,219 ft elevation gain and -7,337 ft loss; the 50K has an estimated +2,004 ft gain and -4,005 ft loss. The 100K includes nine aid stations spaced about 4.5–9 miles and allows drop bags at Bumble Bee, Deep Canyon Ranch, Table Mesa, and the finish. The 50K includes six aid stations spaced about 4.5–8 miles and allows a drop bag at the finish. GU Roctane, gels, electrolyte drink, and a range of food options are listed at aid stations. Pacers are permitted on the 100K starting at Deep Canyon Ranch with one pacer at a time and a possible switch at Table Mesa; pacers must be on foot and sign a waiver.
Other logistics noted: both races are cupless, crew access is limited to specified aid stations, parking at Mayer High School is restricted, and shuttles run between the finish area and the Anthem Outlet Mall. Entry limits are 1,200 runners per distance and registration closes in early February. Visit the organization's website for the most recent information.
