Elevation gain, measured two ways

Source	Gain	vs lidar
Course file (GPX)	3,238ft	+31%
USGS lidar, 1 m	2,467ft	reference

They differ because a GPS file picks up noise on every wiggle and often takes its heights from a coarse terrain model, while lidar maps the ground itself to about a metre. We sampled this route every 98 ft against USGS 3DEP and counted each rise of 10 ft or more, on Oct 30, 2026. The planner still uses the course file.
