True elevation on that ride is basically non-existant.
When I lived there I did a century called the highlander that was quite the ride. Pretty tough climbs, some being 23% grade at the most for a mile long. At time I would do portions of that ride maybe 60-80 miles of it for training. Great ride, beautiful ride, with some of the longest descends in NY (The catskills and adriondecks probably have better ones). Still its one of the most fun rides out there.
