McDowell Mountain Regional Park
Fountain Hills, AZ

Experience the beauty of McDowell Mountain Regional Park on an array of fun and fast courses at the Adrenaline Night Runs. Our new 6K distance is perfect for first time night trail runners and the challenging 10K will push those ready for a new challenge.

2019 Full Moon Waves!
We rolled these races out in 2018 and we’re excited to be offering them again this season! The Full Moon Waves at Adrenaline will allow runners to head out under a peak “Flower” full moon on either the long (10 mile) loop, or the short (10Km) loop. It’s a unique opportunity to run in the middle of the night without a headlamp on!

This race is part of the 2019 Insomniac Night Trail Run Series with events all across the state of Arizona. Join us and “Carpe Noctem” to “seize the night”!

Registration for the 2019 event closes on Tuesday, May 14 at Midnight.

    Trail Etiquette
    -Remember to always remain on designed trails, no short cutting.
    -If you decide to use headphones, please be respectful of runners behind you attempting to pass. -Also, remove ear buds as you approach aid stations or a road crossing.
    -Please do not listen to music on course with a speaker. We know, you listen to the best music- but please use headphones for music.
    -This course includes some legit single track. If you are fast and attempting to pass, please alert the runner in front of you before flying past them. Likewise, if you hear a runner approaching you from behind, attempt to find a spot to allow the runner to pass.

    As a general rule, when passing a runner, announce, “on your left.”
    Uphill runners/hikers have the right of way to downhill runners. Remain in control as you descend and respect the other runners.
    Everyone is after the same goal here so let’s be respectful of each other’s races and have fun. Please.

    For the safety of all runners, no pets are allowed on-course at the night runs. Any pets at the race must be on a leash at all times, respect park rules, and be supervised.
