Alien Run is a 25+- MTB single-track and oil-field road mountain bike ride in Aztec, New Mexico.
The ride is named after the fabled Hart Canyon UFO Crash site. Little green men – or women, whomever you prefer.

The ride / race course is accessed through Aztec New Mexico. We started at the Aztec Motocross track for about 8 miles of Mountain View trail before we got to the Alien run trailhead. From there it was an 8 mile loop. Sandy, twisty singletrack with some slickrock then back to the moto track via Mtn View. Total ride time about 2.75 hrs easy with breaks.

Back to the Mentmore trail…basically the best ride we did in the three days we were there. Fast, hard pack singletrack. Its like riding on a sidewalk at times. Roll with some semi-slicks and you can really haul.
The Mentmore trail is where they hold the Dawn-till-Dusk 12-hour mtb fest in the spring.
