Climbs
biggest firstElevation gain, measured two ways
| Source | Gain | vs lidar |
|---|---|---|
| Course file (GPX) | 5,216ft | +9% |
| USGS lidar, 1 m | 4,801ft | 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 Nov 2, 2026. The planner still uses the course file.
Aid stations as published on the course file
