Test your endurance on a 25 mile loop rolling through McDowell Mountain Regional Park. Whether you tackle the full 100 mile solo, one of our relay events, or just get the gears rolling with the 10 miler, we want to get you out on the trails to ride with us! Utilizing some of the local favorites, the loop will ride portions of Escondido, Pemberton, and the Long Loop trails. Welcome the cooler weather and race through the gorgeous Sonoran desert landscape, with some of the valley’s more iconic peaks in the background. We aim to have the right distance for anyone, so find the ride that suits you best, and saddle up for a great time in the desert!

Back for Year Two!

The Frenzy Gravel Grinder features the best of McDowell Mountain Park with less of the technical and rocky parts. Choose one loop for 25 miles or go two for 50. Can you hang with the big dogs? We have a 100 mile Gravel option as well. New for 2024…we are offering 50 mile duo as well as 100 mile duo and quad Gravel relay categories. Gravel bikes with drop bars are required for all of the gravel categories.



Experience the magic of night trail riding in the Sonoran desert at the Adrenaline Night Trail Rides held on a rolling 9.5 mile loop at McDowell Mountain Regional Park. This is a perfect beginner night ride with distances for all. Ride past towering saguaro cactus under the night stars!

This race is the 2nd in the Insomniac Night Trail Ride Series with events across the greater Phoenix, Arizona area. Join us and “Carpe Noctem” to “seize the night”!
