Relatively well marked and clean. The trail is particularly smooth.

Well maintained!

My friend and I ride this trail from Alameda to Rio Bravo and back, about 32 miles. We started a long time ago when it was first opened, back then only a handful of people would be riding, walking, roller blading along it. I went recently and was blown away by how popular it has become. I strongly recommend going early in the morning. Be sure to put slime in your tires, bring a snack and water. I love that no motorized vehicles are allowed as I'm too old for that, lol. Enjoy your ride/walk just please keep an eye out for old farts like me.

On a vacation from southern California, we rode the trail on a beautiful weekday morn in October of 2015. We parked at the north trailhead, pedaled down as far as the Botanic Garden, then headed back.
We pretty much had the trail to ourselves on a perfect fall day. The trail was flat, straight, smooth, and ideal for those looking for a fast paced workout. Being out-of-staters we were looking forward to majestic views of the mighty Rio Grande, but we were denied due to all of the trees between the river and the trail. On the bright side, at least some fall color was beginning to appear on those trees.
I think the highlights for us were admiring the grand estates that line the trail, and checking off another state on our quest to bike all fifty.

Goes from Unser to Mariposa Park. From there you can take a trail west to Boca Negra Canyon or get on the Riverside trail.

Like was said more of a street tour. Get off just past Montano and go into the Boca Negra Canyon. Try going up the hill inside the canyon. If you can do it you're in good shape. Wide bike lane but be careful..you're in Albuquerque.

We road our mtb bikes therefore able to explore the many multi-use trails that shoot off the paved trail into Rio Grande Valley State Park. There were so many choices of paved, gravel and dirt trails. We did not have any issue with goathead spurs.

Sept 2018: Nice ride, quite flat except for underpasses. It was unexpectedly busy for a Sunday morning, but the first day the ride was great. Loved the scenery, the long straight sections and even the temperature of mid 80s was a relief for us on our two CatTrikes . We parked at Central Ave and rode north and then turned around and headed south, then back to the parking area. A nice ride to work the kinks out after sitting on a tour bus for a week. On the second day, we headed south first just to be different. We didn't make it back to Central before the goat head got me on the left front tire. At home, I normally ride some fairly rough surfaces but I don't usually worry about flat tires. I keep good rubber on all three tires and "thornproof" innertubes on my Cattrikes. Big Mistake! Goat heads are very plentiful and super tough. Ayway, after three days and three flats, we gave up. I think I will investigate airless tires. That would make the riding in that area much more enjoyable. A bit of research on the internet convinced me that the goat head problem will be a continuing problem far into the future. Perhaps a bit of warning to folks coming in from other parts of the country would be in order.

This is more of a sidewalk by a super busy street. You would have to make quite a few stops in your run/walk or ride as there are many street crossings. Nothing scenic about this trail south of I40 unless you like watching cars race.
