Mayhem Night Trail Fort McDowell, AZ   Dec 6, 2025

The McDowell Mountain Frenzy Trail Runs has a corresponding night race – and the Mayhem Sunset Runs will be the third and final race in the Fall Sunset Series! Runners will get to experience the competitive track on a cool December night, providing a unique trail experience as you share the trail with 50 mile runners from our day race, Frenzy, on your way to the finish line.

The 25 Km, 10 Mile & 5 mile courses will all stay within the competitive track trails featuring winding single track trails and short but steep climbs and drops.

Two races, one day! This race will be held on the same day as the McDowell Mountain Frenzy Trail Runs, part of the Desert Runner Trail Series. Finish any distance in both the Frenzy & Mayhem Trail runs to win a unique medal!
