Well, my calculations said about 25 miles, but that was apparently "as the crow flies" and not the bike trail route. Great trail to Amsterdam and a nice lunch, right on the trail, at La Cucina Restaurant. No sign, but you'll see it at the parking area and there's a bike rack on the trail. Then several miles of Bike Route 5 along Route 5S. Yea, we hate road riding but we had to do it. In Rotterdam we picked up the Mohawk Hudson Bike Trail and cruised into the Rotterdam Kiwanis Park for a break. Then it was an easy paved trail ride into Scotia. Then a few city streets in Schenectady to our hotel in the Stockade section of Schenectady. A long, hot day but all's well that ends well.
