The 5.6 mile length of this trail makes it perfect for a short afternoon ride. Excellent surface of fairly new pavement on the entire trail. Fairly scenic with a few very nice vistas, and rest areas with benches at several points. Just be aware the the trail is downhill all the way from Marlborough to Hudson. I started in Marlborough, and the grade didn't seem that steep as I was heading out. On the the return trip, I realized that even a moderate grade can be pretty demanding when you're climbing it for 5 miles without any level breaks. Maybe next time I'll start in Hudson, and get my work out on the way out, then enjoy the downhill coast on the return trip.

Rode the trail on my bike yesterday and it was a nice ride. Parked in Hudsn in the Wilkins St lot and rode it to the end in Marlboro. It was approx 10.5 miles round trip. The trail is well marked and somewhat easy to follow except for 1 intersection when you stop and have to try to figure out which way to go. One section was under repair and had to ride in the street but not for long and you were back on the trail. It's a well kept and clean trail. Would ride it again.

Rode from Hudson to Marlboro & return. One bridge just about finished and another across the river on Rt.62 they just started the work on. Nice tunnel under Rt.209 and some very nice views. All nicley paved. Will be great when it is finished to Acton.

We live in Marlboro and riding from our house to the trail makes it a nice ride for after work. My only complaint is that people walking need to make sure they don't walk 5 or 6 across blocking both sides of the trail. Stay to the right...
