As mentioned by others this HAS been a great trail.
Currently the trail is in very rough shape due to horse traffic. The type of material used last year to resurface the trail is great for walking and wheeled traffic but is damaged when horses are ridden at a gallop.
Recent attempt to ride resulted in my wife and I leaving the trail and finding a paved road to ride back on rather than endure the constant pounding.
I am trying to contact Vermont Dept of Forest ,Parks, and Rec about this but so far have had no luck getting a response.
I will update this review if new info comes or if the status of the trail surface changes,

I do a lot of running and road biking. This trail is great for both. Rolling hill, scenic, great for distant ride/runs. Construction of the trail was completed Fall of 2020. By far my favorite trail in the capital region

First off — skip the northern part of the trail from the Hampton Manor Lake area if you are a biker — and start your trip at Miller Road (just of interstate 90). You will be greeted by a babbling brooks, rolling hills, and the smell of farms. As you head south through Nassau Lake you will have opportunities for food and drinks. This is a fun ride.

This trail is great. There are paved stretches (from East Greenbush to Nassau) with mostly unpaved from Chatham to Hudson (with short stretches of paved in that area). My favorite part is the Nassau area.

I congratulate all who were involved in developing this magnificent route. I rode it from Albany to Voorheesville and back. The way to Voorheesville is 9 miles of gentle up-hill grade until final few miles, which makes the return trip to Albany mostly a gentle downhill ride. This is "rail trail" at it's best!

I live this trail, especially the section from Miller Rd in Schodack to the columbia county line. It's nicely paved a few hills, but mostly flat from Nassau south. Looking forward to riding further into columbia county this year.

I enjoyed biking the trail. I was only able to do areas that construction was completed and the road sections. I used a road bike on the stone dust and did not have a problem. The spots I rode were recently completed and I wonder how the stone dust will fair over the winter. around the Kinderhook area there was a good portion available. Lots of walkers the morning I rode it. I am planning on purchasing a gravel bike with a little wider tires and this will be one of my first rides this summer. I will start in the middle and hopefully make it to both ends the same ride. I want to include both of the train stations in the video even though they are a quarter of a mile from the official endpoints.

I hope to do the complete trail and record sections with a Go Pro in June '21. It will be round trip ride, so it will be double the trail length of 35 miles.

New off road section was created along Broadway in Albany after coming out of the tunnel. Watch for the signs for the Empire Trail also

Starting at nearly sea level on Busy So. Pearl st (and there is new path linking the Mowhak Hudson Trail) you enter a curve which takes you on a bridge over So Pearl, and into unfettered nature. First the Normanskill rapids, pass under the Thruway and 9W, cross an 1850s railbridge over the Normanskill, and you begin segments of a 3-5% climb thru the backwoods of Delmar, probably as the Dutch saw it in the 1600s. There is a rest area by Stewarts where it crosses Delaware. By now you climbed about 200'. Then you continue and cross under the Cherry Ave Extension, to the Slingerlands Rest area. The rest of the trail passes thru Suburban backyards and subdivisions, fields, gradual grades, finally crossing rt 155 and vly creek, and ending at Grove and So Main Street in Voorheesville, elevation 330'. There is a replica train station there.

A great paved surface perfect for inline skating or biking. A true Treasure to the community, and there is some talk in planning materials about westward expansion.
