How it was measured
The course comes from ASO's own published geometry, the same data that draws the stage map on letour.fr, not from a route planner joining towns. VeloWorkout measures 171.2 km from Le Bourg d'Oisans to Alpe d'Huez against the 170.9 km the roadbook prints, and 5,607 m of climbing against a published 5,450 m. Elevation is sampled from the Terrarium elevation model and smoothed, so digital-model noise is not counted as climbing.
Waypoint positions agree with ASO's separately published climb positions to a median of 126 m (worst 236 m).
