Posting this basically just as a reference point for one of New Mexico's most iconic trails, the La Luz Trail.
Here is the Strava Link for a better quality map. My Suunto Ambit2 clocked the run at 12.3 miles with 3,346' elevation gain.
The route is from the La Luz sign at the parking area to the La Luz sign where the trail splits to the summit trail or the South Crest trail. The trail can also be part of the Sandia Watermelon Loop or shortened by riding the tram down the mountain.
