The AZT Oracle Rumble is a trail race held near Oracle, Arizona, north of Tucson along the Santa Catalina Mountains. This annual event features an ultra-marathon at its core, with 50-mile and 50K options. Shorter distances include a Half Marathon, 12K, and 5K, all utilizing the same desert trail system. C.O.D. Ranch presents the race, which benefits the Arizona Trail Association.
The majority of the running takes place on singletrack within Oracle State Park. The longer routes extend onto remote sections of the Arizona Trail. The course is consistently rolling, demanding consistent trail running ability even for shorter distances. The Half Marathon and 12K are contained entirely within the park and have time cutoffs; the 5K does not. Packet pickup occurs at Historic C.O.D. Ranch, a guest ranch adjacent to the park offering views of open land and mountains. The event is cupless, requiring participants to bring their own bottle or cup for aid stations.
