The Alien Run trails fly way below the radar, but mountain bikers in the know rave about this small trail system as one of the best in northwestern New Mexico. While the High Desert Trails near Gallup tend to get more acclaim (partially since they’re located right off I-40), mountain bike explorer extraordinaire John Fisch says he “found Alien Run to be even more entertaining."

“The singletrack here is the real draw as it offers everything from wicked fast juniper dodging on fast and flowy trails to major rock obstacles on the 'Black Hole’ trail,” writes Fisch. "If you’re intrepid enough to find this very remote place, you’ll likely have it all to yourself,” he concludes.

The system is broken into three different loops: The Short Loop, Long Loop, and Outer Limits. The route mapped here incorporates all three loops into one big ride, but note that you can choose to shorten this ride dramatically depending on your fitness, time constraints, and whether or not you’re jiving with the quirky desert singletrack.




Mostly stable trail tread with some variability featuring larger and more unavoidable obstacles that may include, but not be limited to: bigger stones, roots, steps, and narrow curves. Compared to lower intermediate, technical difficulty is more advanced and grades of slopes are steeper. Ideal for upper intermediate riders.
