Overview
The Pemberton Trail 50 km runs in Fountain Hills, AZ, following the established paths of McDowell Mountain Regional Park. With an 8-hour time limit requiring a minimum pace of 9.6 minutes per kilometer, its cut-off is tighter than 84% of 50k peers and more generous than just 16%, leaving little cushion for extended stops or a slow back half.
Dating back to 2017 with 10 past editions, the event draws a mid-sized group. The field is bigger than 47% of 50k events and smaller than 52%, meaning runners experience an uncrowded route along the park's marked trail system. Entry fees range from 75 to 90 $.
