| Course file (GPX) | 7,092ft | -7% |
| USGS lidar, 1 m | 7,594ft | 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 26, 2026. The planner still uses the course file.
