Embrace the unique challenge and magic of the Adrenaline Night Runs on May 23, 2026, held amidst the stunning nocturnal Sonoran desert of Fountain Hills, Arizona. Offering distances for every trail runner, from a 6K introduction to a demanding 50K ultra, alongside 10K, 15K, and 25K options, this event is a highlight of the Insomniac Night Trail Run Series. Typical race day conditions see temperatures starting in the low 90s Fahrenheit and cooling into the upper 60s as the night progresses, with minimal chance of precipitation, providing a refreshing escape from the daytime heat.

The courses, staged out of McDowell Mountain Regional Park's Four Peaks Staging Area, navigate rolling desert single-track trails like Escondido, Scenic, Cinch, and Shallmo. Runners will encounter a blend of fast, smooth sections and more challenging mountainous terrain, sometimes featuring rocky, narrow paths with cacti and dusty stretches, particularly in later miles. Headlamps illuminate your way, revealing the desert's beauty under the stars and providing a truly immersive experience. Aid stations, including a fully stocked main hub at the start/finish and remote stations, offer water, ice, electrolyte drinks, snacks, fruit, and even hot food; however, runners must bring their own reusable cup for this cupless event.

Adrenaline Night Runs has earned a reputation for its excellent organization and vibrant atmosphere, drawing between 100-500 participants annually. Runners consistently praise the unforgettable experience of twilight starts, sunset views over the mountains, and the serene quiet of night running, often describing it as "magical". It's an opportunity to test your limits, connect with the trail community, and discover the desert in a spectacular new light.
