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 174.9 km from Chambery to Voiron against the 174.7 km the roadbook prints, and 2,350 m of climbing against a published 2,200 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 169 m (worst 231 m).
