This page covers what's specific to the men's Tour edition. Data sources, the 50-year baseline method, WBGT estimation, and the pipeline-validation checks are shared across every edition on the platform — see the platform methodology page for the full method.
Stage times are computed in race-local time — Europe/Paris, or Europe/Madrid for the Spanish stages — which is what determines each stage's "today"/upcoming/ completed state.
Each completed stage's "Time on course" line — winner vs. last classified rider for road stages, fastest vs. slowest ride for the two time trials — comes from official published race results, displayed as-is alongside the measured conditions above. We don't compute an exposure window or a temperature range from it; it's shown for readers to weigh against the numbers themselves, not as a derived statistic.
This edition's route elevation follows the open-data method described in the platform methodology page — real intermediate towns densifying the path between known points, never traced from ASO's own profile graphics. We found this directly on stage 2, where a plain Tarragona-to-Sitges chord crossed open water before densification fixed it. A handful of this edition's most rugged mountain stages still retain a small residual overshoot beyond our normal validation tolerance after hand-placing waypoints — disclosed rather than hidden, not survey-accurate, and each stage's elevation profile is labelled as a schematic for exactly this reason.
