The course

Where it goes loop · 6 aid stations · rust marks a stop your crew can reach

Course line from the race's own GPX. Source file. Year of this file not known.

A 50K route from Kentucky Camp with a scenic out-and-back section to Box Canyon before it rejoins the main course. It starts at 6:00 a.m. with the 50 Mile, on its own marked course with its own cutoff: finish by 4:00 p.m.

Rocky, rutted climbs and descents on Forest Service roads, singletrack and the Arizona Trail, with an out-and-back to Box Canyon. The race says it is very runnable in places and that the elevation changes and rugged footing make it a challenge for runners of all abilities.

The race

What this one is

Old Pueblo Endurance Runs is a trail ultra in the Santa Rita Mountains of southern Arizona, with a 50K and a 50 Mile. Both start and finish at the historic mining site of Kentucky Camp and run on Forest Service roads, singletrack and sections of the Arizona Trail, under Mt. Wrightson. It is the last leg of the Southern Arizona Triple 50, and the 50K is part of the Southern Arizona 50K Trifecta.

Old Pueblo began in 1985, started by a group of local trail runners who are still friends. It has had different routes, starts, finishes, distances and race directors over the years, but has always been run on the flanks of the Santa Rita Mountains.
