The climb
Col du Galibier climbs 17.7 km at an average of 6.9%, gaining 1,221 m to a summit at 2,642 m. It is neither relentless nor erratic: the kilometres move either side of the average by a point or two.
The hardest kilometre measures 9.7% and comes in the middle third of the climb, and 5 kilometres of the ascent average more than 8%. The final kilometre eases to 2.4%, which is where the climb gives something back.
Above 2,000 m the air is thin enough to matter: a rider who has not been at altitude loses power over the top of a climb like this regardless of how well it has been paced. It appears on 2 stages in ProPace's data, between 2024 and 2026; each one is listed below and can be ridden in the app.
