In my very humble opinion, it is the most beautiful place in the country.
As a town, it is probably not to the liking of most. It is in many ways very stark. Despite what most know about it--fantastic ski town, artist community, several famous residents--it is a poor town. One of the last vestiges of the Old West. Not always openly hospitable at first, once you settle in, the communities within take great care of their own. A wide variety of characters live there. You find in Taos a live-and-let-live philosophy deeply rooted in the history of the place.
As a place to run, probably not the liking of most. Very small--very few runners at all. Shorter and Pre trained there, so you run in the footsteps of greatness. The Pueblo Revolt of 1680 began there, so you run in the footsteps of history. If you don't mind running solo 98% of the time, then it is a great place to explore. There are many trails and dirt roads to spend your hours. (Don't run on the Mesa, where they don't take kindly to, well, anyone.)
The winters can be snowy at times, but nothing out of the ordinary. A big snow will often be gone in a few days, at least around town.
The summers can be hot, but morning or evening runs are quite beautiful.
Work there is often hard to find. Several friends work two or three jobs to feed their ski/bike-bum lifestyle, and prefer it that way. So to make a living there often takes some creativity.
It is my favorite place in the world.
