Longer than the published length

The line in the dataset measures 674.0 km against a published 576 km (+17.0%).

OpenStreetMap measures 674.0 km against the 576 km (about 358 mi) the Trail Conference publishes to Thacher State Park: the relation carries on past the published terminus over the Adirondack extension, about 108 km, and that extension is not marked as a side route. The line is kept whole.

GPX is simplified to 5 m for devices. GeoJSON is the full-resolution line as published in this dataset. Neither carries elevation.
