Old Pueblo Endurance Runs

Old Pueblo Endurance Runs is a trail ultramarathon held in Sonoita, Arizona on Saturday, March 6, 2027. The event features long-distance trail courses run on the flanks of the Santa Rita Mountains and along the Arizona Trail.

The race began in 1985 and has used different routes and formats over the years while remaining in the Santa Rita Mountains. The course starts at the historic mining site of Kentucky Camp and travels into the rugged terrain near Mt. Wrightson, which rises to 9452' and remains visible from much of the route. The event highlights local trail history and the same trails used by early Native Americans, ranchers, farmers, migrants, and miners.

Distances offered:

  • 50 miles
  • 50 kilometers (50K)

Old Pueblo is part of regional race series and partnerships. It is included in the Southern Arizona Triple 50 and the Southern Arizona 50K Trifecta, which recognize runners who complete multiple designated races in a season. The race is also a Sterling Silver Ticket partner with the Angeles Crest 100; the 1st and 2nd place male and female finishers in the 50 mile event receive Sterling Silver Tickets to Angeles Crest 100, allowing lottery bypass while still requiring registration fees. The event has a reciprocal entry partnership with the PhoMo 50K. Sponsors include local running and food organizations. Visit the organization's website for the most recent information.
