About the race

Sinister Night Runs is a series of night trail races held at San Tan Mountain Regional Park in Queen Creek, Arizona. The event is part of the Insomniac Series and routes run over the San Tan, Hedgehog, Littleleaf and Moonlight trails under nighttime conditions with visible saguaro cacti and rolling desert terrain.

Distances

  • 54K on a 9 km loop repeated six times
  • 27K on a 9 km loop repeated three times
  • 18K on a 9 km loop repeated two times
  • 9K single 9 km loop
  • 6K single lap using Littleleaf and San Tan with a cutback on Moonlight

Each course is run counter-clockwise and is well marked with orange plastic ribbons with black polka dots, reflective medallions, laminated signs, and blue and white checkerboard flagging for wrong way trails. There is one remote aid station on the loop called San Tan Aid which runners pass every lap; the main aid station is stocked with water, ice, electrolyte drinks, salty and sweet snacks, fruit, peanut butter and jelly, bean rollups, and hot items such as quesadillas and grilled cheese. Yeti coolers and buckets will be used on course.

The race is cupless so runners should bring a reusable cup or purchase one onsite. Crews are allowed at the start/finish and pacers are permitted only for 54K runners beginning on loop five. Drop bags are available at the start/finish. Medical staff are based at the start/finish headquarters. Parking at the park is subject to the park entry fee and pets are not allowed on-course.
