**We're super excited to announce our new 50k distance option for our March 6th 2027 event!** As part of our new 50k distance, we've once again joined forces with the Arizona Trail Association, and are offering the unique challenge of completing all three southern Arizona's 50k races, Colossal Vail, Oracle Rumble, and Old Pueblo. New course maps available soon!.
Starting at the historic mining site of Kentucky Camp the race takes you into the rugged, rocky shadow of Mt. Wrightson along the Arizona Trail. Looking down at you from 9452’, it is one of the tallest peaks in southern Arizona. You will seldom lose sight of it as you run the course. It is truly a beautiful area. The course itself, consists of a 25 mile loop on forest service roads and trails through the southeastern part of the Santa Rita Mountains (part of the Arizona Trail). Elevation at Start/Finish is 5142 and ranges between 4031 and 6232 with an average grade of 6%. Time limit: 7 hours for 25 miles and 15 hours for 50 miles.
Special awards will be given to the top three male and female finishers in each event. All finishers will receive awards plus plenty of Swag from our sponsors. Post race cookout also provided.
Old Pueblo is also part of the Southern Arizona Triple 50. Runners who complete three of Southern Arizona’s 50-mile ultra races within a single season are eligible for special prizes and a discounted rate. More information can be found here: https://runazt.org/southern-arizona-triple-50
