Overview

The Barr Lake 50k, organized by Aravaipa Running, is a fixed-distance event that has been held 2 times, most recently in 2026. With 34 finishers in its latest edition, its field size is larger than 47% of 50k races.

The race takes place on a road loop shorter than 5 km, offering continuous views of the water and the front range. Runners have 9 hours to complete the 50 km course, requiring a pace tighter than 60% of 50k races. This means a pace of 10.8 minutes per kilometer or faster is needed to meet the cut-off.
