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 174.8 km against the 175.1 km the roadbook prints, and 821 m of climbing against a published 850 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 44 m (worst 44 m). Climbing total disputed: ASO 850 m against PCS 701 m.
