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
