Race description: The Pemberton Trail 50k and 25k are run completely on trails in the beautiful McDowell Mountain Regional Park, 4 miles NE of Fountain Hills, Arizona. This is a fast course with gently rolling hills (no big climbs). You might set a PR here! You’ll also love the unique, keepsake trophies for overall and age-group winners. With our great volunteers, good food, mild weather and a fun, low-key vibe, it’s always a great day in the desert.
