Black Canyon Ultras
The Black Canyon Ultras present point-to-point trail races on the non-motorized Black Canyon National Recreation Trail in Arizona. The event includes two distances:
- 100K (62.2 miles)
- 50K (32.2 miles)
Both courses begin near Spring Valley at Mayer High School and follow the Black Canyon Trail through the Sonoran Desert. The 100K finishes at Emery Henderson Trailhead near New River; the 50K finishes at Deep Canyon Ranch in Black Canyon City. The routes combine singletrack, jeep roads, and sections of an old stagecoach route, and include multiple creek crossings and an out-and-back at the Black Canyon City aid station on the 100K.
Key statistics are provided for each distance, including time limits (100K - 20 hours; 50K - 11 hours) and estimated elevation changes. The 100K lists +5,219 ft gain and -7,337 ft loss; the 50K lists +2,004 ft gain and -4,005 ft loss. Aid stations supply water, electrolyte drinks, GU Roctane and gels, Gatorade, salt tabs, and a range of food options; spacing ranges roughly 4.5–9 miles on the 100K and 4.5–8 miles on the 50K. Drop bags and crew access are allowed at specified stations; pacers are permitted for the 100K starting at Deep Canyon Ranch with one pacer at a time. The 100K is a Western States qualifier and an associated Golden Ticket allocation is noted for top finishers. Visit the organization's website for the most recent information.
