White Tank Mountain Regional Park, Waddell, AZ

Vertigo is the fifth race in the Insomniac Night Trail Run Series

This race is now part of a five-race Series Pass! DETAILS HERE!

For 2019, with Saturday night offering a full moon and peaking at 3:00 a.m. we are adding in two additional races where you’ll get to run under the full moonlight crossing the midnight hour! Whether you were able to join us for the Sinister Night Runs Full Moon Wave or not, this is a really fun opportunity to run under an actual full moon in the beautiful White Tank Mountain Regional Park!
A new distance added specifically for this race, the 20 Km, will get the Wave kicked off at 11:00 p.m. and the 10 Km (11:30 p.m. start) will count under separate results from the normally scheduled races. Each of these distances will run the same course as the earlier start times.

Double Down!
In 2019, this race will have the unique opportunity to “double down” with our Full Moon Wave races that will begin at 11 p.m. and 11:30 p.m. respectively to give runners a chance to actually run under a full moon at its peak brightness.

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.
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.

Race Timing
We will be utilizing a chip timing system at this event to record your time at the finish. You will be provided with a timing chip attached to the back side of your race bib. It is important to not crease, or fold the the timing chip to ensure your finish time is read.
