Course Summary

It’s happening! Our McDowell Mountain Frenzy Trail Runs has it’s own corresponding night race. New in 2017, our Mayhem Night Runs will complete our Insomniac Night Series! We have set the course up to run the opposite direction of it’s day counterpart, providing our runners a new and unique trail experience into the cool December nights!

Expect cooler conditions during the evening with temperatures typically in the 60’s and low’s that could dip into the 40’s as the night progresses. Please be prepared for “cold” Phoenix conditions during the night. We will have plenty of ice and water but highly recommend that you bring clothing that keeps you warm.

In addition, blue & white checkerboard plastic flagging will be hung to designate non-race or “WRONG WAY” trails. All runners are responsible for understanding the layout of the course. Please familiarize yourself with the course maps on our website prior to race day and/or print a map to bring along with you.

Each site has a large parking area to accommodate up to a 45′ RV and is a “Developed Site,” with water and electrical hook-ups, dump station, a picnic table and a barbecue fire ring. All restrooms offer flush toilets and showers. The south loop of the campground also offers handicapped-accessible restrooms. All sites in the campground may be reserved online at
