Insomniac Night Trail Run Series

The Insomniac Night Trail Run Series consists of eight runs throughout the Maricopa County Regional Parks plus one at Fort Tuthill County Park in Flagstaff. The series runs from April through December. It’s our way of escaping (some of) the summer heat while continuing to race at distances ranging from 5 kilometers to 75 kilometers and dusting off that sweet headlamp. While some of the trails in the Insomniac Night Runs share a few of the same trails as the Desert Runner Trail Series, we have made sure nearly all of the running you’ll do for this series is different from the day time counterpart.

Returning in 2019, our fantastic Insomniac Series Passes are here to save you some money, win some extra schwag, and explore more of the great trails around the valley–all at night! Check out the series pass below!
In addition to the current race perks, a unique Insomniac finisher medal will be awarded to anyone who completes five of the nine races within the entire Insomniac Night Trail Run Series!!

We are also excited to announce that all of our Insomniac Series Trail Runs will again be CUP FREE! We have teamed up with UltrAspire to offer Aravaipa branded reusable cups that will be available for purchase during registration and on race day or feel free to bring your own!

Series Passes

We’ve included the five core Insomniac trail runs that fall during the hottest parts of the Phoenix summer into a Series Pass this year. Choose from the short series (Jitters Pass), middle distance (Wingsuit Pass), trail distance (Vigil) or ultra distance (Delirium Pass).

If you are looking to build up to your first ultra marathon, we are also offering the “Evolution Pass” that will begin with the Sinister 9K in April and culminate with the Jangover 50K in September! Whether you’re looking for an excuse to “drop down” in distance to see what you can do, or looking for that extra push to get you into your first 50K, the Evolution Pass is perfect.

Finishers of all five races within each respective pass will earn an exclusive Insomniac custom finisher medal! If you happen to miss one of these “series” races you can substitute* one of our other insomniac events (Blackout, Thrasher, Punisher, or Mayhem) to still earn the Insomniac medal.

*Race substitution requires an additional entry fee to the above listed events*
**Each pass includes a discount for early bird pricing which will end on April 20, 2019**
