Course Summary

Sinister kicks off our 2020 Insomniac Night Trail Run Series. The first of eight night runs, come run all summer with us!

All races are held on a 9 kilometer loop of the San Tan, Hedgehog & Littleleaf Trails. The 27K runners will complete 3 loops, 18K is two loops, while the 54K ultra division will complete 6 loops, passing through the start/finish line after each lap! The course features a mix of smooth runnable trails with just a few rollers and rocks for fun.
Our new 5 Km course will utilize Littleleaf, San Tan and will cut back on Moonlight to the finish.


Expect warmer running conditions during the evening with temperatures typically starting in the 90’s & cooling as the night progresses. We will have plenty of ice and water at our aid stations.
