| Source | Gain | vs lidar |
|---|---|---|
| Course file (GPX) | 1,958ft | -8% |
| USGS lidar, 1 m | 2,126ft | 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 23, 2026. The planner still uses the course file.

ETAs use the Run Planner’s effort model: climbs slow you, descents give a little back. Margins under 30 minutes are red, under 90 amber. Confirm cutoffs with the race.
