Old Pueblo Endurance Runs
Old Pueblo Endurance Runs takes place on March 6, 2027 near Sonoita, Arizona on the flanks of the Santa Rita Mountains. The event features two trail race distances and runs through remote, rocky terrain and historic landscapes.
The route begins at the historic mining site of Kentucky Camp and follows sections of the Arizona Trail beneath Mt. Wrightson (9452'). Courses traverse desert and mountain terrain that includes fences, gates, and sections of primitive forest and high desert.
Both distances start together and follow separate marked courses with independent cutoff rules. Key cutoff requirements include that 50K runners must finish by 4:00 p.m., and 50-mile runners must return to Kentucky Camp by 1:45 p.m. to begin a second loop; runners who miss required cutoffs will receive a DNF. Dropping from the 50 Mile to the 50K is not permitted.
Aid stations are spaced several miles apart and are stocked with water, electrolyte drink, potatoes, oranges, bananas, chips, m&ms, pretzels, pb&j sandwiches, Coke, ramen, and Scandinavian Swimmers. Drop bag service is available to 50-mile runners only; drop bags must be placed in the designated area and clearly labeled. Pacers are allowed for 50-mile runners aged 60 or older on the second loop and must begin pacing at Kentucky Camp.
Course marking uses flour and colored flagging tape; blue tape indicates incorrect turns. Participants are expected to pack out trash, bury human waste, close gates, and respect the adobe structures at Kentucky Camp. Camping in the national forest is allowed with no fires.
