This site is an informational portal for informal trail runs in the mountains of New Mexico, Southern Colorado, and West (far far west) Texas.

The runs are informal, small-group activities intended to encourage camaraderie rather than competition. There is no sponsoring organization, just a loose-knit group of interested trail runners who enjoy running trails across the landscape of New Mexico (and adjacent parts of Colorado and Texas).

The purpose of this website is to provide coordination and information for those interested in joining the runs.

NOTE: Please contact the Race Directors beforehand of your plans to attend, or you may show up at the start alone.

NOTE: I am in the process of moving the Mountain Trail Series from this blogspot format to a Facebook Group. If you would like to join the group, send me an invitation request (the group will be closed to avoid spamming). During the Spring of 2014 I'll post notices here but eventually all activity will move to Facebook. If you don't "Facebook" and would like email notices, send me a note at --- Thanks! David

For those who can't set up a car shuttle - consider running an out-and-back along the Crest Trail from Placitas at some point you'll run into the crossers. North-end Trail head: Drive 5 miles east of I25 towards Placitas to the Tunnel Spring road then going south and up 1.5 miles till you get to the trail head parking. South-end Trail head: I-40 to the Tijeras exit (as if going to Cedar Crest). Go right towards south 14 road then immediately turn left under the freeway. Drive north a half mile up through the Canyon Estates subdivision to get to the trail head. or 505-695-4839 for further coordination. Hope to see you on Sunday!
